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 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.
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 .
