Question: 145   The ALU of a computer normally contains a number of high speed storage elements called

  1. semiconductor memory
  2. registers
  3. hard disk
  4. magnetic disk
  5. none of the above

Question: 146   Memories in which any location can be reached in a fixed(and short) amount of time after specifying its address is called

  1. sequential -access memory
  2. random-access memory
  3. secondary memory
  4. mass storage
  5. none of the above

Question: 147   Which of the following is the fastest

  1. CPU
  2. magnetic tapes and disks
  3. video terminal
  4. sensor, mechanical controllers
