Generally RAM (random access memory) is measured in:
- (A) Bytes
- (B) M bytes
- (C) K bytes
- (D) Both b and c
- (D) Both b and c
More RAM can make computer:
- (A) Expensive
- (B) Run faster
- (C) Run slower
- (D) Powerful
- (B) Run faster
RAM is called volatile memory because the data stored in it:
- (A) Do not disappear whenever the computer turns off
- (B) Disappear whenever the computer turns off
- (C) CPU can directly access the RAM
- (D) It is very fast
- (B) Disappear whenever the computer turns off
A variation of ROM is:
- (A) Flash memory
- (B) Cache memory
- (C) Programmable read-only memory (PROM)
- (D) Direct access storage
- (C) Programmable read-only memory (PROM)
The number of jobs completed by a computer system per unit time is called:
- (A) Throughput
- (B) Nibble
- (C) Instruction cycle
- (D) Firmware
- (A) Throughput
The memory used to supplement the capacity of main storage:
- (A) Random Access Memory
- (B) Read Only Memory
- (C) Secondary memory
- (D) Cache memory
- (C) Secondary memory
We can search any item by simply specifying:
- (A) The Hard Disk Tracks
- (B) ROM Size
- (C) Address in direct access storage
- (d) None of the above
- (C) Address in direct access storage
The surface of a hard disk is logically divided into:
- (A) Firmware
- (B) SIMMS
- (C) Physically marking tracks
- (D) Pie-shaped sectors
- (D) Pie-shaped sectors
The number of sectors of a hard disk depends upon the:
- (A) Density of the disk
- (B) Speed of the motor
- (C) Number of read/write heads
- (D) Capacity of RAM
- (A) Density of the disk
Typically, the storage capacity of a sector can be:
- (A) 512 bytes or its multiple
- (B) 512 kilobytes
- (C) Always 2 bits
- (D) 1/2Â the capacity of RAM
- (A) 512 bytes or its multiple
