Registers are used for performing the various operations.
How does a register work?
Registers are temporary storage areas for instructions or data. ... Registers work under the direction of the control unit to accept, hold, and transfer instructions or data and perform arithmetic or logical comparisons at high speed .
What is general purpose register?
General purpose registers are used to store temporary data within the microprocessor . ... It is of 16 bits and is divided into two 8-bit registers BH and BL to also perform 8-bit instructions. It is used to store the value of the offset. Example: MOV BL, [500] (BL = 500H) CX – This is the counter register.

How many registers does a CPU have?
The CPU has 8 general- purpose registers, each capable of storing 32-digit binary numbers.In addition to 32-bit data, they can also store 16- or 8-bit data.
Are registers and cache the same?
Cache is a smaller and fastest memory component in the computer. Registers is a small amount of fast storage element into the processor. ... Cache memory is exactly a memory unit .
Which registers can interact with memory?
Which registers can interact with the secondary storage? Explanation: MAR can interact with secondary storage in order to fetch data from it.
What is DMA explain?
Direct memory access (DMA) is a feature of computer systems that allows certain hardware subsystems to access main system memory (random-access memory) independently of the central processing unit (CPU). ... DMA can also be used for “memory to memory” copying or moving of data within memory.
What are the 5 types of shift register?
- Serial in Serial out (SISO) Shift Register.
- Serial in parallel out (SIPO) Shift Register.
- Parallel in Serial out (PISO) Shift Register.
- Parallel in Parallel out (PIPO) Shift Register.
What is difference between register and counter?
Register – is a group of flip-flops. ... Counter – is essentially a register that goes through a predetermined sequence of states . The gates in the counter are connected in such a way as to produce the prescribed sequence of binary states.
