Opening slide
(Slide) |
Welcome to the Spoken Tutorial on Getting to know Computers |
Learning Objectives
(Slide) |
In this tutorial we will learn about
We will also learn to connect the various components. |
Show image of a desktop and laptop
one after the other |
Generally, there are 2 types of computers -
|
Show image of a tab PC | Now-a-days, tablet PCs or tabs for short, are also quite popular. |
Slide | Functions of a computer.
A computer performs five major functions irrespective of their size -
|
Show block diagram on slide | Basic organisation of a computer is as shown in this block diagram.
Program Results & Data
Mouse Storage Unit Monitor Camera Control Unit Arithmetic Logic Unit |
Slide | The Input unit helps to
|
Show images of keyboard, mouse, camera and scanner | Keyboard, mouse, camera and scanner are some of the input devices. |
Slide | The Central Processing unit
|
Show 3D model of CPU
|
Typically, the Central Processing unit or CPU looks like this.
|
Slide | It takes data and instructions, processes them and gives the output or results.
|
Show image of monitor and printer | The unit that supports the process of producing results from the data, is the output unit.
|
Show image of a desktop with the 4 components mentioned | Typically, a desktop computer has 4 main components
|
Show image of printer and scanner connected to a PC | A camera, printer or scanner can also be connected to a computer. |
Show image of monitor
(blank interface) |
This is a monitor or the computer screen, as we call it.
|
Image of Monitor
(with the Ubuntu interface (3 secs) and with the Windows interface (3 secs)) |
It displays the computer's user interface.
|
Image of Keyboard >> then zoom in closer>> place a red border around the character keys and next around the number keys | The keyboard is designed to enter text, characters and other commands into a computer.
|
Image of Mouse
(Point to the 2 buttons and the scroll button with a big red arrow) |
This is the computer mouse. Typically, it has 2 clickable buttons and a scroll button in between.
|
Show a finger clicking the left-mouse button | Pressing the left mouse button, activates most actions.
|
Show a finger clicking the right-mouse button | Pressing the right mouse button, activates more non-standard actions like shortcuts. |
Show the scroll button moving back and forth | The mouse wheel is used to scroll up and down, by rolling the scroll button. |
Image of Mouse | The computer mouse is an alternative way to interact with the computer, besides the keyboard. |
Now, let us see the various parts of the CPU. | |
Front part of the CPU >>Red arrow pointing to the POWER ON switch | There is a prominent button on the front of the CPU which is the POWER ON switch. |
Red/Blue lights appear on the POWER ON switch | To turn on the computer, one needs to press this switch. |
Red arrow pointing to the reset button | There is a reset button, too, which helps us to restart the computer if required. |
Red arrow pointing to the USB ports switch and DVD/CD-ROM reader. | Also, on the front side, you will notice 2 or more USB ports and a DVD/CD-ROM reader-writer.
|
Zoom into the USB ports and show a pen-drive connected to it. | The USB ports are used to connect pen-drives to the computer. |
Show the DVD/CD-ROM reader opening >> and show a CD placed in it >> show closing of the reader. | And the DVD/CD-ROM reader-writer is used to read or write a CD or a DVD. |
Rotate the CPU model to show the back side of CPU | Now let's look at the back of the computer. |
Zoom in to show the USB ports | The ports at the back, are used for connecting the CPU to the other devices of the computer. |
Show 1 or 2 types of cables | This is done using cables. |
Show the internal components of the CPU | There are many components inside the CPU.
|
Show the fans by pointing with a red arrow >> show curved arrow to indicate air flow | Fans at the back provide the air flow required to cool the components.Otherwise, overheating can cause damage to the CPU, often leading to data loss. |
Show the case cooling fan | This is the case cooling fan.
|
Zoom out from previous image >>
Red arrow pointing to the PSU |
Power Supply Unit, also called PSU, supplies power to the computer. |
Now, let's learn how to connect the various components to the CPU. | |
Show all the components on a table | Place all the components on the table, as shown. |
Show all the cables on a table | Place all the cables on the table, as shown. |
Rotate the monitor and show back side. | First, let's connect the monitor to the CPU. |
Show the power cable >> Show the blue part being connected to the CPU
(zoomed in animation to show the part clearly) |
Connect the power cable to the monitor, as shown. |
Show the power plug being connected to a power supply socket. | Now, connect the other end to a power supply socket. |
Show the CPU power cable >> connect it to the CPU | This is the power cable of the CPU.
|
Show the power plug being connected to a power supply socket. | Then, connect it to a power supply socket. |
Show the keyboard cable >> Show the cable head part being connected to the CPU
(zoomed in animation to show the part clearly) |
Next, connect the keyboard cable to the CPU, as shown.
|
Show the mouse cable >> Show the cable head part being connected to the CPU
(zoomed in animation to show the part clearly) |
You can connect the mouse to the port which is “green” in colour. |
Show the mouse cable >> Show the cable head part being connected to the CPU
(zoomed in animation to show the part clearly) Red arrows pointing to the other USB ports |
Alternately, you can connect the USB keyboard and mouse to any of the USB ports.
|
Red arrows pointing to the other USB ports | The remaining USB ports can be used for connecting pen drive, hard disk etc. <PAUSE> |
Show the lan cable | This is a lan cable. |
Show the lan port >> Show the lan cable head part being connected to the CPU
(zoomed in animation to show the part clearly) |
And this is a LAN port.
|
Show the other end of the lan cable head being connected to a wi-fi modem
(zoomed in animation to show the part clearly) |
The other end of the lan cable is connected to a modem or a wi-fi router.
|
Show the blinking led light on/near the lan port. | The led light will blink, when the lan port is active and receiving activity.
<PAUSE> |
Red arrows pointing to the other serial ports | You may notice that there are other serial ports on the CPU.
|
Red arrows pointing to the other parallel ports | You will also notice that there are some parallel ports on the CPU.
|
Red rectangle around the 3 audio jacks | Now, let's look at the audio jacks. |
Red arrow pointing to the pink port | The port in “pink” is used for connecting a microphone.
|
Red arrow pointing to the blue port | The port in “blue” is for connecting a line in, for eg- from radio or tape player. |
Red arrow pointing to the green port | The port in “green” is for connecting headphone/speaker or line out. |
Zoom out and show the back side with all the cables connected as per requirement. | Now that we have connected all our devices, let's turn on the computer. |
Show the power supply buttons on the wall being switched on | First of all, switch on the power supply buttons of the monitor and the CPU. |
Show the switching on of the ON button on the monitor | Next, press the POWER ON button on the monitor. |
Switching the ON button in CPU | And then press the POWER ON switch, on the front of the CPU. |
Show the opening screen when the computer is switched on
You will find images on the net... use it but animate it |
Usually, you will see a string of words on a black screen, when your computer first turns on.
BIOS is the software which gives the CPU its first instructions, when the computer is turned on. |
The whole process of loading the operating system is called booting the computer. | |
Show the desktop interface in Ubuntu | When all the necessary checks are done, you will see the operating system's interface.
|
Show the desktop interface in Windows | If you are a Windows user, you will see this screen.
|
Now, let us briefly look at a laptop. | |
Show image of a laptop | Laptops are portable and compact computers. |
Show image of a laptop on a person's lap | A laptop is small and light enough to sit on a person's lap while in use.
|
Red arrow pointing to the various components as per narration | It has most of the same components as a desktop computer including
built into a single unit. |
Red arrow pointing to the lan port and USB ports as per narration | It also has a lan port and USB ports. |
Red arrow pointing to the video port | There is a video port, using which one can connect a projector to the laptop. |
Red arrow pointing to the mic and earphone icons | The audio jacks are easily identifiable, with respective icons for mic and headphones. |
Red arrow pointing to the cooling fan | This is the inbuilt cooling fan in the laptop.
|
