What is a Register?

Skill/Topic: Memory, Abstract Data Types, and Addresses
A) A register is a small amount of memory within the CPU that is used to temporarily store instructions and data.
Explanation: Random Access Memory is also called a Main Memory. It is called a Volatile memory because; instructions and data contained in main memory are lost once the computer is powered down.

Register is the smallest and fastest unit of memory. Registers reside on the CPU chip and typical size of a register is 32 bits. They hold the current instruction and data required for the current instruction.

A register is a set of bits in micro processor.They store current instructions & store addresses also.

A Register is a group of Flip Flops-each flip flop stores a single bit of memory The Register size is variable depending on number of flip flops.Hence a Register is a small storage device placed closest to cpu

Any CPU has ALU, Memory and IO Units. That memory is the set of Regidters within the CPU. It is to store the data (may be values, addresses and Instruction) Temporarily.

its a collection of flip-flops which r basic memory elements

depending upon the number of flip-flops used size of registers varies.

A register is nothing but a combination of number of flip-flops that has the capacity of storing one bit of information.

Register is a valuable small collection of memory in 2 D.
It is constructed by the numbers of capacitor+transistor+resistor-> (MOSFET)

register basically a group of flip flop . flip flop is the single bit storage cell or it is the smallest memory  cell .
so register is no of flip flop arranged in sequence, if there is 5 flip flop then register is called 5 bit register .
