B RAM

C Non-volatile memory

D PROM

5. The computer memory that needs to be updated is ______?

A DRAM

B SRAM

C ROM

D PROM

6. The memory space of a computer is used to ______?

B keep information temporarily

C provide additional speed when needed

D All the answers are true

7. In a computer, RAM contains data and instructions ___?

A temporarily

B permanently

C for a few minutes

D for one day

8. The computer’s memory is composed of ______?

A set of wires

B set of circuits

C cells

D set of ports

9. If the computer’s memory location is to be read, the CPU places the address in ______?

A MAR

B MBR

C PC

D DOS

The Memory Address Register (MAR) is the CPU register that stores the memory address from which data will be fetched from the CPU or the address to which data will be sent and stored. MAR contains the location of the data in the memory to be accessed. When reading from memory, the data addressed by MAR is fed into the MDR (data register) and then used by the CPU. When writing to memory, the CPU writes the data from the MDR to the memory location with the address stored in the MAR.

10. In a computer, the output of the compiler is called ______?

A program

B source code

C linked code

D object code

Object code is a set of instructions understood by a computer at the lowest hardware level. Object code is usually produced by a compiler that reads higher-level computer language source instructions and translates them into equivalent machine language instructions.
