Updating our storage devices

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”

Write a complete new paragraph talking about pen drives.

Your paragraph should include:

• You use it for …

• It is easy/difficult to carry data

• Capacity

• Price (expensive/cheap)

If in doubt go to page 35.
