Tape drive is connected to and controlled by _______

a) Interpreter
b) Tape controller۔
c) CPU
d) Processor

Magnetic tapes are sequential access devices. They are the secondary storage devices and are used to store large amounts of data

The secondary memory which allows us to store a large amount of data is often referred to as the auxiliary memory

The MAR stands for memory address register. It holds the address of the active memory location.

What is the location of the internal registers of CPU?
a) Internal
b) On-chip
c) External
d) Motherboard

The internal registers are present on-chip. They are therefore present inside the CPU. L1 cache is also present on-chip inside the CPU

Which of the following is independent of the address bus?

a) Secondary memory.
b) Main memory
c) Onboard memory
d) Cache memory

The secondary memory is independent of the address bus. It increases the storage space. It is implemented in the form of magnetic storage devices.

RAM contains the current data and programs and ROM contains permanent programs like BIOS

The main memory mainly consists of RAM and ROM

The size of the main memory depends on the size of the address bus of the CPU.

Registers are the small memory locations which are present closest to the CPU.

Which of the following is the fastest means of memory access for CPU?
a) Registers
b) Cache
c) Main memory
d) Virtual Memory

Cache Memory is the memory closest to the CPU
