Registers are very fast computer memory components. They are also listed on the top of the speed chart of the memory hierarchy. Generally, we measure a register by the number of bits they can hold; for example, an 8-bit register and a 32-bit register hold 8 bits and 32 bits of memory respectively. General Purpose, Segment, EFLAGS, and index registers are the different types of relevant registers we have in the system. They are responsible for performing almost every function in the system, as they hold all the values to be processed. Let's see their types:
