Updating our storage devices

CD-ROM
CD-ROM disks are very common and conform to a standard. They are removable. They are also cheap to make.They used to be read-only but now there are different types of CD-ROM:
CD-ROM R (Read Only Memory) Capacity from 700 MB o 800MB
CD-ROM RW (ReWritable) Capacity from 700MB o 800MB
DVD-ROM R (Read Only Memory) Capacity from 4,7GB o 8GB
DVD-ROM RW (ReWritable) Capacity from 4,7GB o 8GB

Pendrive
We need a USB port. They have a different capacitites from 128MB to 4GB. The standard capacity is 1 or 2GB. So the 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.Yoc can also store programs.So you can install them in another computer or in the pen drive itself.They are becoming cheaper amd cheaper day by day.Nowdays you can get a 2GB pen dirve for less than 20 euros.

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 inject printer, because it is cheaper than a laser printer.










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

You shouldn't buy a printer inject printer because is slowier. You shoul buy a laser printer it is faster.

The Frikyest Mouse

The best mouse

LED mouse
The LED mouse is less sensitive than the laser mouse.

The LED mouse has more problems with suble surfaces, like shining, slick and highly polish surfaces and rough surfaces can be a problem too.


I recommend you the laser mouse because you will have fewer problems with the surfaces.
