Time Narration
00:01 Welcome to the Spoken Tutorial on Getting to know Computers.
00:06 In this tutorial, we will learn about
00:09 the various components of a computer.
00:11 We will also learn to connect the various components.
00:15 Generally, there are 2 types of computers -
00:18 Desktop or Personal Computer and Laptop.
00:23 Now-a-days, tablet PCs or tabs for short, are also quite popular.
00:31 Functions of a computer-
00:33 A computer performs five major functions irrespective of its size:
00:40 It accepts data or instructions by way of input
00:45 It processes data as required by the user
00:50 It stores data
00:52 It gives results in the form of output
00:56 It controls all operations inside the computer.
01:01 Basic organization of a computer is as shown in this block diagram.
01:08 Input unit , 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 organized 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 CPU
02:40 Keyboard 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 the 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, 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
10:23 and how to connect the various components of a desktop.
10:28 Watch the video available at the following link.
10:31 It summarizes the Spoken Tutorial project.
10:34 If you do not have a good bandwidth, you can download and watch it.
10:37 The Spoken Tutorial project team: conducts workshops using spoken tutorials.
10:42 Gives certificates for those who pass an online test.
10:46 For more details, please write to: contact@spoken-tutorial.org
10:52 Spoken Tutorial Project is a part of the "Talk to a Teacher" project,
10:56 supported by the National Mission on Education through ICT, MHRD, Government of India.
11:01 More information on this mission is available at the following link.
11:06 The animation and 3D modeling for this tutorial is done by Arthi.
11:11 This is Nancy Varkey from the spoken tutorial project, IIT Bombay, signing off.
11:16 Thanks for joining.
