00:01:20
in our previous episode we discussed the
00:01:22
different types of computers based on
00:01:24
the principles of operations
00:01:26
like the analog digital and hybrid
00:01:28
computers
00:01:29
we also discussed the types of computers
00:01:31
based on the sizes and functionalities
00:01:34
such as the mainframe mini computers
00:01:36
servers and microcomputers
00:01:38
and talking about the different types of
00:01:40
microcomputers we have desktops
00:01:43
laptops netbooks personal digital
00:01:46
assistants and wearable computers
00:01:48
if you want to go back and watch our
00:01:50
previous episodes all you need to do is
00:01:52
go to our official debit tv youtube

00:01:55
don't forget to subscribe as well okay
00:01:58
thank you for calling tech computer and
00:02:00
services my name is michael how could i
00:02:02
help you
00:02:03
hi i am having problems with my computer
00:02:06
i was also trying to save a document and
00:02:09
it says my memory is full
00:02:11
i don't know what is going on sure let
00:02:14
me help you with your concern
00:02:16
one of the possibilities why your
00:02:17
computer is slow is probably because the
00:02:19
hard disk drive is already full
00:02:22
wait what what is a hard disk drive
00:02:25
sorry i'm not very familiar with the
00:02:27
other parts of the computer
00:02:29
a hard disk drive is one of your storage
00:02:31
devices in your computer
00:02:33
where all the files are being saved you
00:02:36
have probably used up all the storage
00:02:38
space making it difficult for you to
00:02:40
save more files
00:02:41
one of the best things you can do is to
00:02:43
remove unnecessary files that you don't
00:02:45
choose
00:02:46
or if you think all your files are
00:02:48
important you may want to get an
00:02:50
external hard drive you can use to save
00:02:52
up your files and service your backup
00:02:55
oh ok thank you very much for your help
00:02:58
let me work on it today and just in case
00:03:01
it's still slow you can drop your
00:03:03
computer at any tech
00:03:04
center close to you and our computer
00:03:06
technicians will help and fix your
00:03:08
problem
00:03:09
oh that's great i appreciate that a lot
00:03:12
it's always a pleasure to serve you
00:03:14
as a contact center practitioner or even
00:03:17
as a student
00:03:18
it is important that we are familiar
00:03:19
with the different parts of a computer
00:03:21
system
00:03:22
why because by knowing the computer
00:03:25
parts
00:03:25
you will be familiarized with some of
00:03:27
the computer terminologies
00:03:29
at the same time learning the parts may
00:03:32
lead the way for you to soon be able to
00:03:34
fix
00:03:34
upgrade and even perform a maintenance
00:03:37
performance of your computer
00:03:39
students are you familiar with some of
00:03:42
the basic parts of a computer system
00:03:45
if yes well that's good i'm sure that
00:03:47
you have already discussed them in your
00:03:49
previous years at school
00:03:51
if not do not worry because we will
00:03:53
review them and try to see if you still
00:03:55
remember the basic parts of a computer
00:03:57
system
00:03:59
we can categorize computer systems into
00:04:01
three components
00:04:03
we have the hardware the software and
00:04:05
the people where
00:04:07
hardware is the physical or tangible
00:04:09
part of the computer
00:04:11
when you say tangible these are the
00:04:13
parts you can touch
00:04:14
some examples are the monitor keyboard
00:04:17
and mouse
00:04:18
next we have software software is also
00:04:21
known as a program or application that
00:04:24
runs on a computer
00:04:25
it also enables a computer to perform a
00:04:28
specific task
00:04:29
there are two classifications of
00:04:31
software the system
00:04:33
and application software system software
00:04:36
performs
00:04:37
all the operations the computer needs to
00:04:39
run
00:04:40
a perfect example of this is your
00:04:42
operating system like windows for
00:04:44
microsoft
00:04:45
and mac os for apple while application
00:04:48
software performs specific functions
00:04:50
like word processing
00:04:52
video editing and internet browsing
00:04:55
just remember the physical parts of the
00:04:56
computer that can be touched is called a
00:04:59
hardware
00:05:00
and a part of the computer that cannot
00:05:02
be seen or touched is called
00:05:03
software but to make the hardware work
00:05:07
you will need the software in it lastly
00:05:10
we have the peopleware peopleware refers
00:05:12
to the person that chooses the computer
00:05:14
in the development of software and
00:05:16
hardware systems
00:05:18
this includes computer engineers website
00:05:20
designers
00:05:21
computer technicians software designers
00:05:24
and engineers and server administrators
00:05:28
now that we have discussed the three
00:05:30
components of a computer system
00:05:32
let us now have a closer look at the
00:05:34
basic parts found in your computer
00:05:36
system
00:05:38
we have the system unit monitor
00:05:41
keyboard mouse central processing unit
00:05:45
random access memory read only memory
00:05:49
motherboard hard disk drive power supply
00:05:52
unit cooling fans and optical drive
00:05:56
let us have a closer look at each one
00:05:59
the system unit also known as a tower or
00:06:01
the computer case is the main part of
00:06:03
the computer system
00:06:05
it is made of metal or plastic which
00:06:07
holds the computer's main components
00:06:09
including the motherboard central
00:06:12
processing unit or cpu
00:06:14
random access memory read-only memory
00:06:17
ports and power supply also known as a
00:06:20
computer screen or visual display
00:06:22
monitor
00:06:23
the monitor is a standard output device
00:06:25
in a computer
00:06:26
as it displays the image video and text
00:06:29
on the screen
00:06:31
from an old cathode ray tube or crt
00:06:33
monitor
00:06:34
people now want or look for bigger
00:06:36
monitors that have a high definition
00:06:38
resolution display
00:06:40
perfect for an excellent viewing or
00:06:42
gaming experience
00:06:44
what do you use if you want to message
00:06:46
your friends on social media
00:06:48
you use a keyboard the keyboard is the
00:06:52
most commonly used input device and is
00:06:54
divided into four parts
00:06:56
alphanumeric function keys control keys
00:06:59
and numeric keys
00:07:01
in our future episodes we will be
00:07:03
discussing more of the keyboard
00:07:04
and i will also give you some tips on
00:07:06
how to practice and type
00:07:08
without looking at the keyboard so you
00:07:10
better watch out for that
00:07:13
next we have a mouse a computer mouse is
00:07:16
a pointing device that lets you point to
00:07:18
objects on the screen
00:07:20
select open a program click on a folder
00:07:23
scroll and move files around what's good
00:07:26
about the mouse is it gives the user
00:07:28
more freedom to move your cursor in any
00:07:31
direction on the monitor
00:07:33
you can open a file by double clicking
00:07:35
it close or open a document with a
00:07:37
single click
00:07:38
drag a photo to its folder and much more
00:07:41
the mouse just made the computer much
00:07:43
easier to use
00:07:46
remember when i mentioned about the
00:07:47
system unit or do you still remember
00:07:49
some of the parts that i have mentioned
00:07:52
if you do very good because that is what
00:07:54
we are going to have a look at now
00:07:56
let us now check some of the parts that
00:07:58
are found inside the system unit
00:08:01
first we have the cpu or the central
00:08:03
processing unit
00:08:05
the central processing unit is also
00:08:07
called a processor and is considered the
00:08:09
brain of the computer
00:08:10
why because it controls the operation of
00:08:13
all the parts of the computer
00:08:15
the purpose of a processor or the cpu is
00:08:18
to perform the actual calculations
00:08:20
done by the computer they carry millions
00:08:23
of calculations per second
00:08:25
it's quite impressive when you think of
00:08:27
it a memory is just like the human brain
00:08:30
it can store information events
00:08:32
knowledge that we can use in the future
00:08:35
similarly the computer's memory is used
00:08:37
to store programs
00:08:38
and data computer memory also has two
00:08:41
types
00:08:42
the primary and the secondary under the
00:08:45
primary storage we have the random
00:08:47
access memory and the read only memory
00:08:50
random access memory is also called the
00:08:52
main memory ram is used to store the
00:08:55
programs and data being used by the cpu
00:08:57
in real time
00:08:59
the data on the ram can be read written
00:09:02
and erased any number of times ram is a
00:09:05
volatile memory which means once the
00:09:07
system
00:09:08
shuts down all data stored in the memory
00:09:10
will be lost
00:09:12
the other type of memory is the
00:09:14
read-only memory it is used primarily in
00:09:16
the startup
00:09:17
process of a computer system rom is a
00:09:20
non-volatile storage and it does not
00:09:22
require constant power to retain
00:09:24
information stored on it
00:09:26
when the power is lost or turned off a
00:09:29
rom chip will still keep the data stored
00:09:31
on it
00:09:32
so again remember read only memory is
00:09:34
only used in the startup process of your
00:09:37
computer
00:09:37
while random access memory temporarily
00:09:40
stores
00:09:41
files you are currently using like
00:09:43
writing a document
00:09:45
editing photos and videos for your blog
00:09:47
or even playing online games on your
00:09:49
computer
00:09:50
however under the ram once you switch
00:09:53
off the computer
00:09:54
all the information is lost unless you
00:09:57
store all your files in your secondary
00:09:59
storage
00:10:00
like your hard disk drive a hard disk
00:10:02
drive sometimes abbreviated as the hard
00:10:05
drive
00:10:05
hd or hdd is a non-volatile data storage
00:10:09
device
00:10:10
again when we say non-volatile it refers
00:10:13
to the data or
00:10:14
information that stays in the computer
00:10:17
even when it's switched off
00:10:19
hard drives are commonly used as the
00:10:20
main storage device on a computer
00:10:23
it stores your operating and system
00:10:25
software and other files on your
00:10:27
computer like
00:10:28
photos videos office files
00:10:31
music and so much more over the years
00:10:34
the demand for higher storage space has
00:10:36
increased
00:10:37
and now most computers have a storage
00:10:39
capacity as much as
00:10:40
one terabyte that is like 250 000 photos
00:10:45
taken with a 12 megapixel camera
00:10:48
250 movies or 500 hours of high
00:10:50
definition videos
00:10:52
or 6.5 million document pages and it is
00:10:55
also equivalent to 1
00:10:57
300 physical filing cabinets of paper
00:11:00
that is massive a motherboard is the
00:11:04
main circuit board and one of the most
00:11:06
essential parts of the computer system
00:11:09
the motherboard connects all of the
00:11:10
computer's parts such as the central
00:11:12
processing unit
00:11:14
memory hard drives and other ports and
00:11:16
expansion cards connected to the
00:11:18
motherboard directly
00:11:20
or via cables and because it holds all
00:11:22
the pieces together
00:11:24
we can also call the motherboard the
00:11:26
backbone of the computer system
00:11:29
since the computer is an electronic
00:11:30
device electricity is needed for it to
00:11:33
work
00:11:33
and that's when the power supply unit
00:11:35
comes in
00:11:37
found on the back of the system unit the
00:11:39
power supply unit is the piece of
00:11:41
hardware that converts the power
00:11:43
provided from the outlet into usable
00:11:45
power for the many parts of your
00:11:46
computer
00:11:48
cooling fans a cooling fan is a hardware
00:11:51
device that keeps the overall
00:11:52
temperature of a computer
00:11:54
by circulating air to or from the
00:11:56
computer
00:11:57
the cpu handles millions of calculations
00:12:00
every second
00:12:01
this is the reason why a cooling fan is
00:12:03
necessary to disperse
00:12:04
that heat maintaining your computer's
00:12:06
cooling system can increase their lives
00:12:09
and reduce the chance of damage to the
00:12:11
other parts inside your system unit
00:12:14
and lastly we have the optical disk
00:12:16
drive
00:12:17
a type of optical drives reads and
00:12:20
writes data from
00:12:21
optical disks through laser beam
00:12:22
technology
00:12:24
this type of drive allows a user to
00:12:26
retrieve
00:12:27
edit and delete the content from the
00:12:29
optical disk such as a compact disc
00:12:32
digital versatile disk or dvd and
00:12:35
blu-ray disc
00:12:36
optical drives are among the most common
00:12:39
computer components
00:12:40
although optical disk drives are still
00:12:42
in existence today
00:12:44
they have become less used since
00:12:46
software movies and music can often be
00:12:48
downloaded from the internet
00:12:51
well there you have it students i hope
00:12:52
that you're able to understand our topic
00:12:54
about the basic parts of the computer
00:12:57
and if you are still a little bit
00:12:58
confused let me summarize it for you in
00:13:01
an infographic
00:13:02
here are the three components of a
00:13:04
computer system we have
00:13:06
the hardware the software and the people
00:13:08
where
00:13:09
any computer part that can be touched is
00:13:11
considered hardware
00:13:13
and parts of the computer that can be
00:13:14
seen but cannot be touched are software
00:13:18
under software we have two types the
00:13:20
system software and the application
00:13:22
software
00:13:23
lastly we have the peopleware who uses a
00:13:26
computer
00:13:27
in developing software and hardware
00:13:29
systems
00:13:31
now let us move on to the basic parts of
00:13:33
the computer system
00:13:34
let us first look at the parts that we
00:13:36
see on the outside
00:13:37
like the monitor keyboard mouse
00:13:40
and a system unit when we look at the
00:13:43
computer parts found
00:13:44
inside a system unit you will find the
00:13:47
following
00:13:48
like motherboard central processing unit
00:13:51
read only memory random access memory
00:13:55
cooling fan power supply unit hard disk
00:13:58
drive
00:13:59
and optical drive if you want to get a
00:14:02
copy of this infographic
00:14:04
you can go to our tle9 facebook page
00:14:06
that you see on the screen
00:14:08
