A.Read each statement and decide if it is true or false.
1.Secondary storage devices for large computers consist of removable packs , fixed disk drives , and RAID storage systems ( )
2. Hard Disks may be affected by a head crash , when particles on the read / write heads come into contact with the disk‘s surface( )
__________________________________________________ _____________
B.complete the following with the suitable words.
1. The term primary storage refers to --------- --------- where both data and instruction are temporarily held for immediate access and use by the microprocessor .
2. primary storage is considered ---------------- of storage meaning that the data and instructions are lost when the computer is turned off.
3. Secondary storage refers to ------------- ------------- or any storage device designed to retain data and instructions in a relatively permanent form.
4. Secondary storage is----------,meaning that saved data and instructions remain intact when the computer is turned off.
5. -------- -------- are files containing software instruction where ------------- ------------ are files that contain data .
6.A ----------- ---------- is a removable round flat piece of plastic that stores data and programs as magnetic spots.
7. A----------- ----------- is a device that holds, spins, and read data from and writes data to a floppy disk .
8.---------- means the disk drive copies data stored as magnetic slots from the diskette.
9. -------- means the disk drive transfers data represented as electric signals within the computer memory onto the disk.
10.The device by which the data on a disk is transferred to the computer ,and from the computer to the disk, is the disk‘s----------------------
11.On a diskette,data is recorded in rings called -----------------.
12.-------------------refers to the number of bytes per inch that can be written onto disk surface.
13.The -------------------------------feature allows you to protect a disk being over written .
14.--------------------------- are thin but rigid metal patterns covered with a substance that allows data to be held in the form of magnetic spots.
15.An------------------------ is a removable disk on which data is written and read through the use of laser beams.
16.-------------stands for compact disk-read-only-memory.
17.---------Refers to technology that presents information in more than one medium, including text graphics, animation,video,sound,and voice.
18.------------- is a method of removing redundant elements from a computer file so that it requires less storage space.
19. All disks must be---------------- Before they can store data.
