What are the two memory register called?
Memory buffer register (MBR), also known as Memory data register (MDR) Memory address register (MAR)
Which is correct for memory address register?
The memory address register is half of a minimal interface between a microprogram and computer storage; the other half is a memory data register. In general, MAR is a parallel load register that contains the next memory address to be manipulated. For example, the next address to be read or written.
What are the types of register memory?

What are the two major categories for register?
The two main categories of processor registers are shown below: Memory Address Register (MAR). Memory Buffer Register (MBR).
Why are special registers needed?
We have discussed general purpose registers as being discrete memory locations within the CPU used to hold temporary data and instructions. A special purpose register is one that has a specific control or data handling task to carry out. There are a number of special purpose registers within the CPU.
What is the function of the memory address register?
memory address register (MAR) – holds the address of the current instruction that is to be fetched from memory, or the address in memory to which data is to be transferred. memory data register (MDR) – holds the contents found at the address held in the MAR, or data which is to be transferred to main memory.
What is register how many types?
There are two types of registers. Some registers are internally in the processor while the other one is user-accessible. These two types of registers differ in their accessibility to computer architecture.
What is a register and its types?
Registers are a type of computer memory used to quickly accept, store, and transfer data and instructions that are being used immediately by the CPU. The register holding the memory location is used to calculate the address of the next instruction after the execution of the current instruction is completed.
What is the purpose of IP register?
A special-purpose register, usually called the instruction pointer (IP) or program counter (PC), keeps track of what instruction is being executed.
What is register and examples?
The definition of a register is a book, list or record of dates, events or other important pieces of information. An example of a register is a listing of people married in a specific church. An example of to register is to sign up for a class.
