Do registers have addresses?

Registers are the internal processor storage. They do not have memory addresses, because they do not reside in memory. You identify them by their names: EAX, for example.

What is an address register used for?

Address registers are designed to make it easy to index into the array of constant registers. The address registers allow you to provide a signed integer offset into the constant registers.

What is the purpose of the data register and address register?

For example, a data register may store individual values referenced being by a currently running program. An address register contains memory addresses, which reference different blocks of memory within the system RAM.

What is meant by address register?

A. A high-speed circuit in a computing device that holds the addresses of data to be processed or of the next instruction to be executed. The number of bits in the register determines the amount of memory that can be addressed. For example, a 32-bit register can address 4GB.

What do you mean by address bus?

computers. : an element in a computer CPU that transmits the location of stored information The address bus allows the CPU to send the address to RAM, and the data bus allows the actual data transfer to the CPU.

What is the role of an address bus?

An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.

What is the main purpose of an address bus?

The sole purpose of an address bus is to identify the address of the location in cache or main memory that is to be read from or written to. Each location in memory will have its own unique address, this is known as addressability.
