  • 00:00:06
    good day Learners and welcome to module
  • 00:00:08
    1.1 of your grade
  • 00:00:10
    10 cat textbook okay so we're going to
  • 00:00:14
    be starting with an introduction to
  • 00:00:17
    computers and let's see what we have
  • 00:00:20
    install for you today so we're going to
  • 00:00:21
    be looking at what a computer is in
  • 00:00:23
    introduction to Windows bit of Hardware
  • 00:00:26
    software um and the information
  • 00:00:28
    processing cycle um so let's get stuck
  • 00:00:31
    in now the first question we need to ask
  • 00:00:34
    here is well what is a
  • 00:00:37
    computer I mean many of us see all of
  • 00:00:39
    these devices but what exactly is a
  • 00:00:41
    computer how do we Define it because it
  • 00:00:44
    could be a laptop it could be a
  • 00:00:47
    smartphone it could even be a
  • 00:00:49
    tablet in the past this is what we
  • 00:00:52
    defined as just being a computer but
  • 00:00:56
    obviously things have changed technology
  • 00:00:58
    has moved forward
  • 00:01:00
    um we talk about
  • 00:01:02
    desktops that we used to work with but
  • 00:01:04
    now you can see we have moved onto a lot
  • 00:01:07
    of the newer Technologies but when we
  • 00:01:09
    talk about a computer we're talking
  • 00:01:11
    about something that is multi-purpose
  • 00:01:13
    which means it can do more than one
  • 00:01:14
    thing it's an electronic device and many
  • 00:01:18
    of them like these over here are
  • 00:01:20
    portable now portable in when we talk
  • 00:01:22
    about computers doesn't mean that I can
  • 00:01:25
    just pick it up and I can walk around
  • 00:01:26
    with it no that's not what it means it
  • 00:01:29
    means means that it can operate on a
  • 00:01:32
    battery or using a battery so I can work
  • 00:01:35
    with it on the goal I can't do that with
  • 00:01:37
    this okay so when we use the general
  • 00:01:42
    term computer we're talking about all of
  • 00:01:44
    these devices so there is a typical one
  • 00:01:48
    and we can Define it this way we can say
  • 00:01:51
    that a computer is an electrom
  • 00:01:53
    mechanical device that does a job of
  • 00:01:57
    work for the user okay does that
  • 00:02:01
    computer do something on its own no it's
  • 00:02:02
    actually doing something for the user so
  • 00:02:05
    that's one way of uh defining our
  • 00:02:08
    computer also it consists of two main
  • 00:02:11
    parts and that's namely your Hardware so
  • 00:02:14
    that's the physical things we're talking
  • 00:02:16
    about here things that you can touch
  • 00:02:19
    things that you can see and then
  • 00:02:21
    software which is related to the
  • 00:02:23
    programs that are going to be running on
  • 00:02:26
    this piece of Hardware okay now let's
  • 00:02:30
    look at some of these here we first of
  • 00:02:32
    all going to look at the hardware and
  • 00:02:33
    like I just mentioned Hardware are those
  • 00:02:36
    parts that are physical they can be seen
  • 00:02:39
    they can be touched so we've got things
  • 00:02:41
    like our power supply our printers our
  • 00:02:43
    monitors keyboard mouse hard drive
  • 00:02:46
    optical drive and don't stress when you
  • 00:02:48
    see all these things because we will be
  • 00:02:50
    going through these things in detail and
  • 00:02:52
    all of these components are found inside
  • 00:02:56
    this box okay so this is what we mean
  • 00:02:58
    when we talk about
  • 00:03:01
    Hardware software is a little different
  • 00:03:04
    software is basically coded instructions
  • 00:03:06
    that run all aspects of the computer in
  • 00:03:10
    other words these are
  • 00:03:12
    instructions that tell the hardware that
  • 00:03:15
    tells this
  • 00:03:16
    hardware and other software what to do
  • 00:03:20
    so it's one thing to have these pieces
  • 00:03:23
    of Hardway in place but you are going to
  • 00:03:25
    need a program um that tells the
  • 00:03:29
    computer what it actually needs to do
  • 00:03:31
    with that right I mean it's like you're
  • 00:03:32
    taking a printer you plug it in and then
  • 00:03:35
    what it doesn't just work you need a
  • 00:03:38
    piece of software that's going to tell
  • 00:03:39
    the PC listen this is a printer this is
  • 00:03:41
    what it does um and then you can start
  • 00:03:44
    working with
  • 00:03:45
    it now we also have different types of
  • 00:03:47
    computers for example you have something
  • 00:03:49
    called a super computer now these are
  • 00:03:53
    high powerered large computers and we're
  • 00:03:56
    talking about a lot bigger than your
  • 00:03:58
    normal desktops
  • 00:04:00
    right um there are large computers used
  • 00:04:03
    by big corporations and governments for
  • 00:04:05
    example NASA uh different universities
  • 00:04:08
    whenever you need to do massive amounts
  • 00:04:11
    of
  • 00:04:12
    calculations okay think about that huge
  • 00:04:15
    calculations does NASA need to do that
  • 00:04:17
    yes do some of our government
  • 00:04:19
    institutions need to do that yes then
  • 00:04:22
    you also have something called a main
  • 00:04:25
    frame I want you just to get your head
  • 00:04:27
    around all these different types of
  • 00:04:30
    computers these are also very powerful
  • 00:04:33
    computers but they are used to control
  • 00:04:36
    major networks for example Banks also
  • 00:04:40
    universities large companies right
  • 00:04:43
    especially when you have companies um
  • 00:04:45
    that span a large over a large area as
  • 00:04:48
    well um so just get to grips with the
  • 00:04:51
    difference between your main frame and
  • 00:04:54
    your supercomputer then the one that we
  • 00:04:57
    really uh chat about quite a lot are the
  • 00:05:01
    servers now again a server is going to
  • 00:05:04
    be more powerful than your general
  • 00:05:07
    desktop machine all right so that's the
  • 00:05:10
    first thing but what does the server do
  • 00:05:12
    as the name implies if someone is a
  • 00:05:15
    server it means they are rendering a
  • 00:05:17
    service so this is a powerful computer
  • 00:05:20
    that provides services for a network and
  • 00:05:24
    that's why it's called a server their
  • 00:05:27
    services include things like printing
  • 00:05:30
    email and storing files this is a
  • 00:05:32
    definition that's going to stick with
  • 00:05:33
    you all the way through to grade 12 so
  • 00:05:37
    do not forget what a server is and some
  • 00:05:41
    of the services that it
  • 00:05:42
    renders now most of us are familiar with
  • 00:05:45
    this we see the gaming PCs the gaming
  • 00:05:49
    desktops and this is really what we call
  • 00:05:51
    our our personal computer it is a single
  • 00:05:55
    computer for home or office use whether
  • 00:05:57
    you are doing gaming at really doesn't
  • 00:05:59
    matter um but you are still using it at
  • 00:06:02
    home or office use and it's usually
  • 00:06:04
    found on a
  • 00:06:05
    desktop so guys this is why this type of
  • 00:06:09
    computer uh is called a desktop machine
  • 00:06:12
    because it's usually found on top of the
  • 00:06:14
    desk okay uh it sounds silly but that's
  • 00:06:18
    that's why they've named it that um
  • 00:06:21
    think about a laptop where do you use
  • 00:06:23
    the laptop most on your
  • 00:06:26
    lap okay
  • 00:06:28
    um Right Moving On we then also have our
  • 00:06:32
    mobile devices now most of us have
  • 00:06:35
    mobile devices and yeah they tell us and
  • 00:06:37
    we know that they are electronic devices
  • 00:06:39
    we don't have an issue with that usually
  • 00:06:41
    handheld now look at that
  • 00:06:44
    portable right do not forget that that
  • 00:06:46
    is something that is very important it's
  • 00:06:48
    something that does come up you do get
  • 00:06:49
    questioned on that quite a bit what does
  • 00:06:52
    the term portability mean when it comes
  • 00:06:55
    to mobile devices now this helps the
  • 00:06:58
    user with the diary dates calendars
  • 00:07:03
    notes I mean these days with your
  • 00:07:05
    smartphones and tablets you can do so
  • 00:07:07
    much more but what you need to remember
  • 00:07:09
    is if it's a mobile device it's an
  • 00:07:12
    electronic device first of all and it is
  • 00:07:15
    portable so all of these devices work
  • 00:07:17
    with
  • 00:07:21
    batteries then another one our
  • 00:07:23
    smartphone again a term that comes up
  • 00:07:26
    often smartphones or devices that com
  • 00:07:29
    Bine functions of a phone with Computing
  • 00:07:32
    abilities have you ever looked at a
  • 00:07:34
    Smartphone when you when you go and buy
  • 00:07:36
    it and you see the same specs as you do
  • 00:07:39
    with a computer you're looking at the
  • 00:07:41
    CPU you're looking at Ram you're looking
  • 00:07:43
    at all these pieces of Hardware um
  • 00:07:45
    that's no different from the hardware
  • 00:07:47
    that's now found in our computers okay
  • 00:07:50
    so these devices bring all the functions
  • 00:07:53
    of different devices into a single
  • 00:07:55
    device now think about that what can
  • 00:07:58
    your smartphone do can you use a camera
  • 00:08:02
    on it do you have a video camera do you
  • 00:08:05
    have an audio recorder do you have a
  • 00:08:09
    calendar um you know there's there's
  • 00:08:11
    just so so many other features but these
  • 00:08:14
    and and this is why they call it
  • 00:08:15
    converging devices or the term
  • 00:08:17
    convergence which just means that we
  • 00:08:20
    bringing um the functions of separate or
  • 00:08:23
    different devices into a single device
  • 00:08:25
    in the past you had a dedicated digital
  • 00:08:28
    camera on its own a video camera on its
  • 00:08:30
    own um a music player on its own now our
  • 00:08:35
    smartphones have everything built into
  • 00:08:38
    it okay so um for test and exam purposes
  • 00:08:42
    please always remember what a smartphone
  • 00:08:43
    is and then this term
  • 00:08:45
    convergence as
  • 00:08:47
    well then let's take a deeper dive into
  • 00:08:49
    our hardware and software now we already
  • 00:08:51
    said that Hardware um is dealing with
  • 00:08:54
    the physical parts of a computer that we
  • 00:08:56
    can touch and see things like our mou
  • 00:08:59
    Mouse monitor keyboard printer and the
  • 00:09:01
    parts inside this computer box those are
  • 00:09:03
    all the things um the physical parts
  • 00:09:06
    that we can touch and see our software
  • 00:09:09
    here we see examples of our software we
  • 00:09:11
    said these are coded instructions or
  • 00:09:13
    Specific Instructions that we give the
  • 00:09:15
    computer to get it to do something
  • 00:09:18
    useful we use Microsoft Word to do what
  • 00:09:22
    to be able to in its simplest form type
  • 00:09:24
    out letters right so we are using this
  • 00:09:27
    piece of software to do something
  • 00:09:29
    useful um we also have multi-purpose
  • 00:09:32
    tools means there is the ability to run
  • 00:09:35
    different types of programs okay so just
  • 00:09:39
    understand the difference between
  • 00:09:41
    hardware and software so having said
  • 00:09:45
    that why then is a smartphone or why um
  • 00:09:49
    Can a smartphone also be regarded as a
  • 00:09:52
    computer and here has a little
  • 00:09:54
    screenshot of a few of the icons and
  • 00:09:56
    apps on a
  • 00:09:58
    smartphone now we need to remember that
  • 00:10:01
    each one of these apps on your phone
  • 00:10:04
    they enable it to do much more than just
  • 00:10:06
    make calls right remember in the past
  • 00:10:09
    your old cell phones were just there to
  • 00:10:13
    send a message and to make a phone call
  • 00:10:15
    that was it the reason we now call these
  • 00:10:18
    new devices smartphones is because they
  • 00:10:19
    can do so much more and the apps or
  • 00:10:22
    programs or software applications enable
  • 00:10:26
    it to do much more than just make calls
  • 00:10:28
    I mean yeah you've got messenger you can
  • 00:10:29
    check in with a school with a D6 you can
  • 00:10:32
    go and have a look at what's um you know
  • 00:10:34
    some of your hobbies and favorite things
  • 00:10:35
    on Pinterest uh send a message or video
  • 00:10:38
    call Via WhatsApp so all of those things
  • 00:10:43
    um enable us to call a smartphone or
  • 00:10:46
    regard a smartphone as a computer has it
  • 00:10:49
    got the same Hardware as a computer the
  • 00:10:51
    same things it's also got Ram CPU um
  • 00:10:55
    hard drive all of these things so that
  • 00:10:57
    is why it falls within that term now
  • 00:11:01
    here's something that's going to be with
  • 00:11:03
    you all the way through until grade 12
  • 00:11:06
    in fact all of this stuff um and this is
  • 00:11:08
    the information processing cycle so this
  • 00:11:11
    is how information is processed when it
  • 00:11:14
    comes to any Computing device we start
  • 00:11:17
    with the input so this is really talking
  • 00:11:21
    about how the data is you know put into
  • 00:11:26
    the device if I'm for example and I'm
  • 00:11:28
    going to use the example of um entering
  • 00:11:31
    someone's number on your phone what do
  • 00:11:33
    you do you first have to type that
  • 00:11:35
    number out then the processing of the
  • 00:11:38
    data takes place this is now where the
  • 00:11:41
    person as they type in the number the
  • 00:11:44
    cell phone checks to see if you've
  • 00:11:46
    already got that
  • 00:11:49
    number do you have it maybe you do maybe
  • 00:11:52
    you don't the output is the result so
  • 00:11:55
    now we see okay I've now got that yeah I
  • 00:11:57
    can see the number I can see the
  • 00:11:59
    person's name and once I save it I've
  • 00:12:02
    then got my storage here as well okay
  • 00:12:05
    this you must know we need to know the
  • 00:12:09
    steps we also need to be able to
  • 00:12:11
    identify certain devices with this um
  • 00:12:14
    and it is something important especially
  • 00:12:16
    in grade 12 okay so here we go again and
  • 00:12:20
    this is why I'm showing you different
  • 00:12:22
    things so that you can get your head
  • 00:12:23
    around the information processing cycle
  • 00:12:26
    the input this is the data I spoke about
  • 00:12:29
    right the processing this is where we
  • 00:12:31
    dealing with our Ram in other words our
  • 00:12:35
    our hardware and just in very simple
  • 00:12:38
    form our output will display the results
  • 00:12:42
    so whatever we do here with the
  • 00:12:44
    processing the results fall under
  • 00:12:47
    output let's use the example again
  • 00:12:50
    there's your cell phone you adding a
  • 00:12:52
    contact to your smartphone with the
  • 00:12:54
    input you are typing in the context
  • 00:12:55
    details using the keyboard process where
  • 00:12:59
    the smartphone checks if it is
  • 00:13:01
    already um saved on the phone you can
  • 00:13:05
    then store it in other words save it and
  • 00:13:09
    then your with your output of message is
  • 00:13:11
    displayed on the screen showing that the
  • 00:13:13
    contact either exists or it's now been
  • 00:13:17
    added because you've saved it because
  • 00:13:18
    it's a new contact right now this is all
  • 00:13:23
    based on the following for grade 10 you
  • 00:13:26
    must know the difference between between
  • 00:13:29
    data and information so
  • 00:13:34
    data it's defined in two words it's just
  • 00:13:37
    raw facts unprocessed facts so giving me
  • 00:13:42
    somebody's cell phone number no name
  • 00:13:44
    nothing you just give me a cell phone
  • 00:13:46
    number that is just
  • 00:13:47
    data right it's raw when I when I take
  • 00:13:51
    that and I add that with maybe the
  • 00:13:54
    person's name their address things like
  • 00:13:56
    that then it becomes more useful ful to
  • 00:13:59
    me and then it becomes information so if
  • 00:14:03
    this is
  • 00:14:04
    unprocessed facts then here we're
  • 00:14:07
    talking about it now being processed and
  • 00:14:10
    it becomes useful that's when it now
  • 00:14:13
    becomes information so data raw facts
  • 00:14:17
    information some have defined it as
  • 00:14:20
    processed um facts or useful or our data
  • 00:14:25
    that has been turned into a more useful
  • 00:14:27
    form and that's where we get
  • 00:14:30
    information right now when we look at
  • 00:14:35
    windows I mean most of us have phones
  • 00:14:37
    tablets laptops desktops when you switch
  • 00:14:40
    it on you know you either have Windows
  • 00:14:43
    or some other kind of operating system
  • 00:14:45
    so let's just get to grips with this the
  • 00:14:48
    first thing we need to know is the
  • 00:14:50
    following when we press that power
  • 00:14:52
    button and everything begins to load
  • 00:14:55
    this is what's known as the booting
  • 00:14:57
    process this is where the operating
  • 00:14:59
    system Windows or whichever one you have
  • 00:15:02
    whether it is your smartphone as well
  • 00:15:04
    and you're using iOS or Android or
  • 00:15:07
    whatever it is the operating system is
  • 00:15:09
    automatically loaded when the computer
  • 00:15:11
    is switched on right you restart your
  • 00:15:14
    phone the same thing is happening that
  • 00:15:16
    is called the booting
  • 00:15:20
    process when I get past this process I
  • 00:15:24
    get to a point where I need to start
  • 00:15:26
    entering my details and then I can log
  • 00:15:30
    onto the system I can log on to my
  • 00:15:33
    smartphone desktop laptop with a
  • 00:15:36
    username and a password and this then
  • 00:15:38
    gives me access to my own files and data
  • 00:15:44
    okay so always just know the difference
  • 00:15:47
    between logging on and booting up to
  • 00:15:52
    totally different
  • 00:15:54
    things and then we have our desktop so
  • 00:15:57
    for those not famili familiar with this
  • 00:15:59
    this is really the first look at a uh
  • 00:16:02
    Windows desktop this is and sometimes
  • 00:16:05
    this is the question that comes up what
  • 00:16:07
    is the first screen that you see after
  • 00:16:10
    you log on or log in um and that is your
  • 00:16:14
    desktop you can see that we also have
  • 00:16:17
    icons on our desktop we've got a start
  • 00:16:20
    button um Windows 10 Windows 11 a lot of
  • 00:16:24
    them use this layout you can change it
  • 00:16:27
    but these are not known as your tiles
  • 00:16:30
    you've also got a quick launch taskbar
  • 00:16:32
    which is customizable so you can pop in
  • 00:16:35
    the programs that you use quite often um
  • 00:16:39
    and you can then just click on that and
  • 00:16:41
    it'll open that particular program and
  • 00:16:43
    then on the right hand side this is
  • 00:16:46
    where we have our notification area so
  • 00:16:49
    let's just go into some detail
  • 00:16:50
    again as we look at the taskbar now
  • 00:16:53
    remember the taskbar is this bottom
  • 00:16:55
    section
  • 00:16:56
    right so what we want to see here again
  • 00:17:00
    from the left far left will always be
  • 00:17:02
    your start button then like I said
  • 00:17:04
    you've got your quick launch icons and
  • 00:17:06
    this is customizable this whole bar down
  • 00:17:10
    here is our taskar right this area is
  • 00:17:15
    just a quick launch area or our quick
  • 00:17:18
    launch taskbar area and this section of
  • 00:17:21
    the taskbar is our notification area and
  • 00:17:24
    then all the way over to the right hand
  • 00:17:27
    side we have our date and time um and
  • 00:17:31
    well in this case they just mention in
  • 00:17:33
    the clock but you can see we've got the
  • 00:17:34
    date as well okay now we can use the
  • 00:17:40
    start menu to do many common things and
  • 00:17:43
    I'm and I'm taking you through this so
  • 00:17:44
    we just have the basics um in place we
  • 00:17:48
    can start programs we can open commonly
  • 00:17:51
    used files we can search for files um we
  • 00:17:54
    can log off we can switch off the
  • 00:17:57
    computer uh there are a number of things
  • 00:17:59
    you can see when this one was opened it
  • 00:18:01
    gives us all of this it shows us the
  • 00:18:02
    various programs here as well um so we
  • 00:18:05
    can do all of those things now when we
  • 00:18:08
    open up a normal um let's say folder or
  • 00:18:11
    window we end up getting
  • 00:18:14
    this and in this case this person opened
  • 00:18:17
    up the
  • 00:18:19
    documents um folder and we can see this
  • 00:18:24
    details pane which shows us what is in
  • 00:18:27
    that particular folder
  • 00:18:28
    now this will be the same if I double
  • 00:18:30
    click on a folder on the desktop and it
  • 00:18:32
    opens up like this I'll have my details
  • 00:18:35
    section where I can see exactly what is
  • 00:18:37
    inside that folder on the left hand side
  • 00:18:39
    I've got my navigation pane so that will
  • 00:18:41
    tell me exactly where I am and I can use
  • 00:18:44
    this to move between different uh areas
  • 00:18:48
    of my PC as well then over here I've got
  • 00:18:52
    my toolbar so the toolbar is up there
  • 00:18:55
    and this displays buttons and menus for
  • 00:18:58
    commment commands things like printing
  • 00:19:00
    emailing creating a new folder Etc I've
  • 00:19:03
    also gotten the top left hand corner my
  • 00:19:06
    back and forward button so maybe I
  • 00:19:08
    opened this and I went into this
  • 00:19:10
    particular folder I can just click back
  • 00:19:12
    to go to the previous area I was in
  • 00:19:15
    whether that be a folder or wherever on
  • 00:19:19
    top I've got my address bar so this
  • 00:19:21
    displays the location of the folder
  • 00:19:23
    that's currently open and you can see
  • 00:19:25
    this one shows us that we are in the
  • 00:19:27
    library
  • 00:19:29
    section and inside that we are in the
  • 00:19:31
    documents folder so that we know exactly
  • 00:19:33
    where we are right we also have our
  • 00:19:36
    title bar here on top where we can click
  • 00:19:39
    on this and move the window um we've got
  • 00:19:42
    our minimize maximize and close buttons
  • 00:19:44
    and we've got our search box to search
  • 00:19:47
    for any items within the particular
  • 00:19:50
    folder that we have
  • 00:19:53
    open okay hope we still
  • 00:19:55
    together then we will always talk about
  • 00:19:59
    you know computers servers and users so
  • 00:20:02
    just so you understand a user is someone
  • 00:20:05
    who utilizes a computer or network
  • 00:20:08
    service they simply use the computer as
  • 00:20:11
    a tool to provide a service so if I want
  • 00:20:14
    to type out my assignment or if I want
  • 00:20:16
    to create a letter what am I doing I'm
  • 00:20:18
    going to be using the computer as a tool
  • 00:20:21
    in order to get that letter right so
  • 00:20:26
    please do not forget what a user is we
  • 00:20:31
    also need to understand each user using
  • 00:20:33
    a computer can be distinguished from one
  • 00:20:36
    another how because they have their own
  • 00:20:40
    user profile so when you log into a
  • 00:20:43
    computer you log in with your username
  • 00:20:45
    and password you'll have certain
  • 00:20:46
    shortcuts you'll have certain folders
  • 00:20:48
    based on what you did on that PC things
  • 00:20:51
    you've saved things you've moved around
  • 00:20:54
    Etc when somebody else logs into that
  • 00:20:57
    it's going to be be set up for their
  • 00:20:59
    particular profile based on what they
  • 00:21:02
    have done on that computer now in a
  • 00:21:05
    Windows envirment a user profile is a
  • 00:21:08
    record of as I mentioned user specific
  • 00:21:12
    data right user specific data that
  • 00:21:16
    defines a user's working environment so
  • 00:21:18
    two people can log on to the same
  • 00:21:20
    machine at different times and they
  • 00:21:22
    might have different backgrounds they
  • 00:21:23
    might have um different folder
  • 00:21:26
    structures based on the specific data so
  • 00:21:30
    the users the person using it but the
  • 00:21:32
    way they've customized how they use the
  • 00:21:34
    PC within windows that is going to be
  • 00:21:36
    the user profile okay now in order for
  • 00:21:40
    us to log in we we use passwords and
  • 00:21:43
    this is something that I know many
  • 00:21:46
    people have a tough time with because we
  • 00:21:49
    have so many things that we log
  • 00:21:51
    into what happens with passwords we
  • 00:21:54
    often forget them right now
  • 00:21:58
    that is normal so what do we do to
  • 00:22:01
    actually count it that we create one
  • 00:22:03
    password that will remember and we use
  • 00:22:05
    it on all of devices that is not right
  • 00:22:10
    okay I know I'm guilty of that myself
  • 00:22:12
    but that is actually not right your your
  • 00:22:15
    username and your password authenticates
  • 00:22:17
    you as a valid user on that particular
  • 00:22:20
    um laptop desktop on your phone those
  • 00:22:24
    type of things now when it comes to pass
  • 00:22:28
    words we need to Bear the following in
  • 00:22:31
    mind we should be changing them
  • 00:22:34
    regularly they should consist of um
  • 00:22:38
    numbers and letters there should be some
  • 00:22:40
    uppercase and lower case like here for
  • 00:22:42
    example um you can see lowercase in
  • 00:22:45
    other words small letters uppercase
  • 00:22:48
    capitals um it should be a minimum of
  • 00:22:50
    six but no more than
  • 00:22:52
    30 and the same character cannot be used
  • 00:22:55
    consecutively for example flaw so we've
  • 00:22:58
    got the two o's there um but I know as
  • 00:23:01
    as as much as I say these things it is
  • 00:23:05
    difficult to remember all of these
  • 00:23:07
    passwords if you are having a different
  • 00:23:09
    password for everything you log
  • 00:23:11
    into and you're changing them every
  • 00:23:15
    month okay so but this is what we should
  • 00:23:18
    be doing this is also a typical test
  • 00:23:21
    question and exam question all the way
  • 00:23:23
    through from grade 10 to grade 12
  • 00:23:26
    looking at um what is some of the
  • 00:23:28
    recommendations for having a strong
  • 00:23:33
    password this is what you will
  • 00:23:36
    use right now the one thing that Windows
  • 00:23:39
    does is it gives us what's known as a
  • 00:23:42
    graphical user interface this means the
  • 00:23:45
    way we work with Windows is through
  • 00:23:48
    Graphics right now we are able to use a
  • 00:23:54
    mouse that Mouse allows us to click and
  • 00:23:57
    double click and right click and drag
  • 00:24:00
    and
  • 00:24:00
    scroll so while we are working with
  • 00:24:04
    these icons you know like your folders
  • 00:24:07
    and your uh little icons for files and
  • 00:24:09
    things we can use the mouse then to
  • 00:24:12
    click on those things double click right
  • 00:24:14
    click drag
  • 00:24:16
    Etc now when it comes to Windows there
  • 00:24:19
    are some common features of programs so
  • 00:24:24
    you know that within cat we work a lot
  • 00:24:27
    with Microsoft Office now Microsoft
  • 00:24:30
    Office consists of word excel PowerPoint
  • 00:24:32
    and and access those are the main four
  • 00:24:36
    that we end up working with but have a
  • 00:24:38
    look at this if you look at this this is
  • 00:24:41
    an Excel spreadsheet that is a Word
  • 00:24:44
    document this is Microsoft Paint and
  • 00:24:48
    what do we see do all of them have a
  • 00:24:50
    title bar yes do all of them show us the
  • 00:24:53
    active window yes do we have a taskbar
  • 00:24:57
    do we are we able to resize or move a
  • 00:25:00
    window right we we've got all these
  • 00:25:03
    things there's minimize maximize close
  • 00:25:05
    I've got it through all those windows
  • 00:25:06
    I've got the title bar over there um I
  • 00:25:08
    can move back and forward I can save do
  • 00:25:11
    you see that there are common features
  • 00:25:14
    within Windows through all of their
  • 00:25:16
    programs right they do this purposefully
  • 00:25:20
    so that it's easy for you to work with
  • 00:25:24
    the
  • 00:25:26
    software
  • 00:25:28
    okay then probably one of the most
  • 00:25:31
    important items is saving your work I
  • 00:25:34
    mean there's no point you do an entire
  • 00:25:36
    presentation or an entire um assignment
  • 00:25:39
    and you don't save it now the current
  • 00:25:44
    work that you are doing on a computer is
  • 00:25:47
    kept temporarily in memory and when we
  • 00:25:51
    go further into hardware and software
  • 00:25:53
    you'll understand more in terms of what
  • 00:25:55
    we are speaking about there
  • 00:25:58
    but to keep that work you have to save
  • 00:26:01
    it to some sort of permanent storage and
  • 00:26:03
    this is where we save our documents our
  • 00:26:06
    presentations whatever it is onto the
  • 00:26:09
    actual computer that we are working in
  • 00:26:12
    we
  • 00:26:13
    save these you know whether it's files
  • 00:26:17
    whatever we we we are busy with
  • 00:26:18
    presentations Etc and we try to organize
  • 00:26:22
    those files into
  • 00:26:24
    folders we also want to look at giving
  • 00:26:27
    our file and folders meaningful names I
  • 00:26:30
    mean let's say you did an assignment
  • 00:26:33
    on weather
  • 00:26:35
    patents and you save it as
  • 00:26:40
    Gio now when you forget where you put
  • 00:26:42
    the document and you do a search what
  • 00:26:45
    are you going to be searching for you're
  • 00:26:46
    going to be searching for weather
  • 00:26:47
    patterns but it's going to find nothing
  • 00:26:50
    because we haven't given it a meaningful
  • 00:26:53
    name okay so remember when we save our
  • 00:26:56
    work what we are currently working on
  • 00:26:57
    before we save it that sits in memory
  • 00:27:00
    then we save it to storage so that it's
  • 00:27:02
    there
  • 00:27:03
    permanently and we then save those files
  • 00:27:07
    into folders and we make sure that our
  • 00:27:09
    files and folders have meaningful names
  • 00:27:13
    now I'm sure you've heard of um computer
  • 00:27:18
    keyboards being a quiry keyboard I know
  • 00:27:21
    when some of the the first cell phones
  • 00:27:23
    that had like full keyboards on them I
  • 00:27:25
    think the old blackberries were one of
  • 00:27:26
    the first
  • 00:27:28
    um they always mentioned that they had
  • 00:27:29
    quy keyboards now that is just a
  • 00:27:33
    reference to the fact that it's a full
  • 00:27:35
    keyboard number one but it's in
  • 00:27:38
    reference to the first six letters that
  • 00:27:42
    we see on the top row of our keyboard
  • 00:27:45
    that's that's really what they're
  • 00:27:46
    talking about and a keyboard is used
  • 00:27:48
    there to do what to input data right
  • 00:27:53
    when we input data into our
  • 00:27:56
    smartphone there we see see and this is
  • 00:27:58
    probably one of the worst features when
  • 00:27:59
    it comes to smartphones is that your
  • 00:28:01
    keyboard is
  • 00:28:02
    displayed um by software on the screen
  • 00:28:05
    it takes up half of your screen but it
  • 00:28:07
    can display letters alphabetically
  • 00:28:09
    rather than in a quity layout so you'll
  • 00:28:11
    see that layout is different to what our
  • 00:28:15
    traditional keyboard is like
  • 00:28:19
    okay now keyboard skills and I hope your
  • 00:28:22
    teachers are going to be going through
  • 00:28:24
    this with you um ideally when you type
  • 00:28:27
    out on a keyboard and I'm talking about
  • 00:28:30
    a physical keyboard that you have um
  • 00:28:33
    with your laptop
  • 00:28:35
    desktop uh if you're going to be using a
  • 00:28:37
    USB or wireless keyboard the this is
  • 00:28:40
    really where your fingers should be so
  • 00:28:43
    from your left hand little pinky it
  • 00:28:45
    should be on a s DF your thumbs are on
  • 00:28:49
    the space bar then we continue with your
  • 00:28:51
    right index which is on J then K then L
  • 00:28:57
    and and then our semicolon now you might
  • 00:28:59
    be asking okay but sir why do we find
  • 00:29:04
    three letters the the idea is when you
  • 00:29:07
    are comfortable with this you should be
  • 00:29:11
    able to use your little finger on the
  • 00:29:14
    left hand just as an example you should
  • 00:29:17
    be able to use it not just for a but to
  • 00:29:20
    go to q and
  • 00:29:23
    z are you with me let's let's let's take
  • 00:29:26
    another one
  • 00:29:29
    um let's use our index on the left hand
  • 00:29:33
    side do you see that your index should
  • 00:29:35
    be able to while you're starting on if
  • 00:29:38
    you should be able to reach r v g t and
  • 00:29:44
    B okay and this is why when you start
  • 00:29:47
    practicing this and you get this right
  • 00:29:50
    you will be able to type on a keyboard
  • 00:29:52
    without even looking at
  • 00:29:55
    it right and so attend that brings us to
  • 00:29:58
    the end of our first module we looked at
  • 00:30:00
    what is a computer the introduction to
  • 00:30:02
    Windows saving our work and also an
  • 00:30:06
    introduction to our
  • 00:30:13
    keyboard
