Pen drives

The pen Drives

You need usb port. They have different capacities from 128 mb to 4gb. The standard capacity is 1 or 2 gb, so they have much more capacity than a floppy disk.
They are faster and very easy to carry. You can store all kind of files and folders. You can also store programes, so you can install them ir another computer or in the pen drive itself. They are becoming cheaper and cheaper day by day. Nowadays you can get a 2gb pen drive for less than 20 €.

CD'S

Our book needs a bit of updating. You have to
rewrite the paragraph on CD-ROM.
Talk about capacity
Revise and change the following sentences
“they are usually read-only”.
Talk about CD-ROM R/WR and DVD R/WR.
Here you have a useful sentence: “They can hold from …MB to …MB”

We need a printer...

Claire: I need to print in colour, but I don’t mind if it is not fast. What kind of printer should I buy?

- You should buy an inkjet printer. Because the inkjet printer is more cheaper than laser printer but it is more slowlier.




Marshall: I need to print really fast. I’m not going to use colour or images. Shall I buy an inkjet printer?

- Don't buy an inkjet printer because it is slowlier. You should buy a laser printer because it is faster.

What are they for?

I want to talk about the output and input devices of PC:

Keyboard.









You can input dates with keyboard.

A mouse is used to move the cursor rapidly.

Using Scanner you can introduce documents in pc.

Joystick.












Joysticks are used in many games to control the game screen.

Microphone.

The most freaky mouse is..

The best mouse

Laser mouse and LED mouse

The laser mouse has less problems with sutle surfaces, like shining surfaces, slick or hightly polished wood and rough surfaces becouse a laser mouse is more sensitive than a LED mouse.





Laser mouse









LED mouse









In my opinion the laser mouse is better than other mouses.

The best computer is..
