| 00:06
| இந்த டுடோரியலில் நாம் கற்க போவது

|-
| 00:09
| ஒரு கணினியின் வெவ்வேறு பாகங்கள்.

|-
| 00:11
| அந்த பாகங்களை இணைக்கவும் கற்க போகிறோம்.

|-
| 00:15
| பொதுவாக, இருவகை கணினிகள் உள்ளன

|-
|00:18
| ''' டெஸ்க்டாப்''' அல்லது '''பெர்சனல் கம்ப்யூட்டர்''' மற்றும் '''லேப்டாப்'''

|-
| 00:23
| தற்போது, '''tablet PCகள்''' அல்லது சுருக்கமாக '''tab'''களும், மிக பிரபலமாக உள்ளன.

|-
| 00:31
| ஒரு கணினியின் செயல்பாடுகள்.

|-
| 00.33
| ஒரு கணினி அதன் அளவு எதுவாக இருந்தாலும் ஐந்து முக்கியமாக செயல்படுகளை செய்கிறது-

|-
| 00.40
| இது உள்ளீட்டின் மூலம் '''data''' அல்லது ''' instructionகளை''' ஏற்கிறது.

|-
| 00.45
| இது '''data''' ஐ பயனருக்கு தேவையானபடி செயல்படுத்துகிறது

|-
| 00.50
| இது '''data''' ஐ சேமிக்கிறது

|-
| 00.52
| இது வெளியீட்டு வடிவில் முடிவைத் தருகிறது

|-
| 00.56
| இது கணினியின் உள்ளே உள்ள அனைத்து செயல்பாடுகளையும் கட்டுப்படுத்துகிறது

|-
| 01:01
| Basic organisation of a '''computer''' is as shown in this block diagram.

|-
| 01:08
| '''Input unit '''

|-
| 01:09
| '''Central Processing unit '''

|-
| 01:11
| '''' Output unit '''

|-
|01:14
|The ''' Input unit''' helps to

|-
|01.16
|enter the '''data''' and '''programs''' into a '''computer''' system in an organised manner

|-
| 01.23
| ''' Keyboard, mouse, camera''' and '''scanner''' are some of the '''input devices.'''

|-
| 01.31
| The ''' Central Processing unit '''

|-
| 01:33
| performs '''operations''' like '''arithmetic''' and ''' logical''' operations and

|-
| 01.38
| stores '''data''' and '''instructions '''
|-
| 01.41
| Typically, the ''' Central Processing unit''' or '''CPU''' looks like this.

|-
| 01.48
| It has many ''' ports''' in the front and at the back of the '''unit. '''

|-
|01.53
|We will learn about them in a little while.

|-
| 01.57
| It takes '''data''' and '''instructions''', processes them and gives the '''output''' or results.

|-
| 02:05
| The task of performing '''operations''' is called '''processing. '''

|-
| 02:11
| The '''output''' is then stored along with the '''data''' and ''' instructions''' in the '''storage unit. '''

|-
| 02:18
| The unit that supports the process of producing results from the data, is the '''output unit.'''

|-
| 02.26
| '''Monitor''' and '''printer''' are some of the '''output devices. '''

|-
| 02.33
| Generally, a '''desktop computer''' has 4 main components

|-
| 02.38
|'''Monitor'''

|-
| 02.39
| '''CPU'''

|-
| 02.40
| ''' Keyboard'''

|-
| 02.41
|and '''Mouse '''

|-
| 02.43
| A ''' camera, printer''' or '''scanner''' can also be connected to a computer.

|-
| 02.50
| This is a '''monitor''' or the '''computer screen''', as we call it.

|-
| 02:55
|It looks like a '''TV screen.'''
|-
| 02.57
|It is the '''visual display unit''' of a '''computer. '''

|-
| 03.02
| It displays the '''computer's user interface. '''

|-
| 03.05
|*One can open various '''programs''' and interact with the '''computer''', using the keyboard and mouse.

|-
| 03.13
|The ''' keyboard''' is designed to enter text, characters and other commands into a '''computer.'''

|-
| 03.21
|This is the '''computer mouse.'''
|-
| 03.24
| Typically, it has 2 clickable buttons and a '''scroll''' button in between.

|-
| 03.31
| Pressing the ''' left mouse button''', activates most actions.

|-
| 03.35
| Pressing the ''' right mouse button''', activates more non-standard actions like shortcuts.

|-
| 03.43
|The '''mouse wheel''' is used to scroll up and down, by rolling the '''scroll button. '''

|-
| 03.49
| The ''' computer mouse''' is an alternative way to interact with the '''computer''', besides the ''' keyboard. '''

|-
| 03.57
| Now, let us see the various parts of the '''CPU.'''

|-
| 04:02
| There is a prominent button on the front of the '''CPU''' which is the ''' POWER ON''' switch.

|-
| 04:08
| To turn on the '''computer''', one needs to press this switch.

|-
| 04.14
| There is a '''reset''' button, too, which helps us to restart the '''computer''', if required.

|-
| 04.21
| Also, on the front side, you will notice 2 or more ''' USB ports''' and a ''' DVD/CD-ROM reader-writer. '''

|-
| 04.30
|The ''' USB ports''' are used to connect ''' pen-drives''' to the ''' computer. '''

|-
| 04.35
| And the ''' DVD/CD-ROM reader-writer''' is used to read or write a ''' CD''' or a '''DVD.'''

|-
| 04.43
| Now let's look at the back of the ''' computer. '''

|-
| 04.48
|The '''ports''' at the back, are used for connecting the '''CPU''' to the other devices of the '''computer. '''

|-
| 04.55
|This is done using '''cables.'''

|-
| 04.58
|There are many '''components''' inside the '''CPU. '''

|-
| 05:02
|When the ''' computer''' is on, all these components work and generate heat.

|-
| 05:08
|Fans at the back provide the air flow required to cool the components.

|-
| 05.14
|Otherwise, overheating can cause damage to the '''CPU,''' often leading to '''data''' loss.

|-
| 05:21
|This is the '''case cooling fan. '''

|-
| 05:23
|It keeps the temperature of the '''CPU''' normal and prevents overheating.

|-
| 05:30
|''' Power Supply Unit,''' also called '''PSU''', supplies power to the computer.

|-
| 05:37
|Now, let's learn how to connect the various components to the '''CPU.'''

|-
| 05.42
|Place all the components on the table, as shown.

|-
| 05:46
|Place all the cables on the table, as shown.

|-
| 05:51
|First, let's connect the '''monitor''' to the '''CPU. '''

|-
| 05:55
|Connect the '''power cable''' to the ''' monitor''', as shown.

|-
| 06.00
|Now, connect the other end to a '''power supply socket'''.

|-
| 06.04
|This is the '''power cable''' of the CPU.

|-
| 06.08
|Connect it to the '''CPU,''' as shown.

|-
| 06.11
|Then, connect it to a '''power supply socket'''

|-
| 06.14
|Next, connect the ''' keyboard cable''' to the '''CPU,''' as shown.

|-
| 06.19
|The '''port ''' for the ''' keyboard''' is usually “purple” in colour.

|-
| 06.23
|You can connect the mouse to the port which is “green” in colour.

|-
| 06.28
|Alternately, you can connect the ''' USB keyboard''' and '''mouse''' to any of the '''USB ports. '''

|-
| 06.35
|The remaining ''' USB ports''' can be used for connecting ''' pen drive, hard disk''' etc.
|-
| 06.42
|This is a ''' LAN cable.'''

|-
| 06.44
|And this is a '''LAN port.'''

|-
| 06.46
|It is a ''' wired connection''' that allows a '''computer''' to connect to a '''network'''.

|-
| 06.52
|The other end of the ''' LAN cable''' is connected to a ''' modem or a wi-fi router. '''

|-
| 06.58
|You will learn about configuring ''' wi-fi connections''' in another tutorial.

|-
| 07.03
|The ''' LED light''' will blink, when the ''' LAN port''' is active and receiving activity.

|-
| 07.10
|You may notice that there are other '''serial ports''' on the '''CPU. '''

|-
| 07.15
|These are used for connecting ''' PDAs, modem''' or other '''serial devices.'''

|-
| 07.21
|You will also notice that there are some '''parallel ports''' on the '''CPU.'''

|-
| 07.25
|These are used for connecting devices like ''' printer, scanner''' etc.

|-
| 07.31
|Now, let's look at the ''' audio jacks.'''

|-
| 07.34
|The '''port''' in “pink” is used for connecting a '''microphone.'''

|-
| 07.38
|The '''port''' in “blue” is for connecting a '''line in,''' for eg- from a radio or tape player.

|-
| 07.45
|The ''' port''' in “green” is for connecting '''headphone/speaker''' or '''line out.'''

|-
| 07.51
|Now that we have connected all our devices, let's turn on the '''computer. '''

|-
| 07.57
|First of all, switch on the '''power supply''' buttons of the '''monitor''' and the '''CPU.'''

|-
| 08.03
|Now, press the ''' POWER ON''' button on the '''monitor.'''

|-
| 08.07
|And then press the ''' POWER ON''' switch, on the front of the '''CPU.'''

|-
| 08.12
|Usually, you will see a string of words on a black screen, when your '''computer''' first turns on.

|-
| 08.18
|This is the '''BIOS system''' displaying information about

|-
| 08.22
|the '''computer's central processing unit, '''

|-
| 08.25
|information about how much memory the '''computer''' has,

|-
| 08.28
|and information about the hard disk drives and floppy disk drives.

|-
| 08.33
|'''BIOS''' is the software which gives the '''CPU''' its first instructions, when the '''computer''' is turned on.

|-
| 08.41
|The whole process of loading the '''operating system''' is called '''booting''' the '''computer. '''

|-
| 08.48
|When all the necessary checks are done, you will see the '''operating system's interface. '''

|-
| 08.54
|If you are an '''Ubuntu Linux''' user, you will see this screen.

|-
| 08.58
|And If you are a '''Windows''' user, you will see this screen.

|-
| 09.02
|Now, let us briefly look at a '''laptop.'''

|-
| 09.06
|'''Laptops''' are portable and compact '''computers. '''

|-
| 09.09
|A ''' laptop''' is small and light enough to sit on a person's lap, while in use.

|-
| 09.16
|Hence, it is called a ''''laptop. '''

|-
| 09.18
|It has most of the same components as a ''' desktop computer''' including

|-
| 09.23
|a '''display, '''

|-
| 09.24
|a '''keyboard, '''

|-
| 09.25
|a ''' touchpad,''' which is the pointing and navigating device

|-
| 09.29
|a ''' CD/DVD reader-writer''' and

|-
| 09.32
|'''mic''' and ''' speakers''' built into a single unit.

|-
| 09.36
|It also has a ''' lan port''' and ''' USB ports.'''

|-
| 09.40
|There is a ''' video port,''' using which one can connect a ''' projector''' to the '''laptop. '''

|-
| 09.46
|The ''' audio jacks''' are easily identifiable, with respective ''' icons''' for ''' mic''' and '''headphones'''.

|-
| 09.53
|This is the inbuilt ''' cooling fan''' in the '''laptop. '''

|-
| 09.57
|This helps to keep the ''' laptop''' from overheating.

|-
| 10.01
|A ''' laptop''' is powered by electricity via an ''' AC adapter''' and has a ''' rechargeable battery. '''

|-
| 10.09
|Hence, it is portable and can be used away from a power source.

|-
| 10.16
|Let us summarize. In this tutorial we have learnt

|-
| 10.20
|about the various components of a ''' desktop''' and ''' laptop '''

|-
