They are becoming cheaper day by day.Nowadays you can get a 2GB PEN DRIVE for less than 20euros.

Printers

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.

OPTICAL MICES

Optical mouse: ( Laser mouse )
An optical Mouse is more sensitive than a wheeled mouse, because it does not have moving parts.
The dirt can not enter the mouse so it has a better response

I advice you to buy an optical mouse because it's better.




Led mouse:
I don't prefer the Led mouse , because the Led mouse is less sensitive than the Optical mouse.

It has a higher chance of failure in subtle surfaces like shiny, slick or highly polished wood and rough surfaces.








Laser Mouse/Led Mouse are both optical mice but the Laser mouse is better than the led mouse.
That's why I prefer the Laser Mouse.
