What Does MAR Stand For in Computer Science?

Computer science is a rapidly-changing field, with new technologies and terminology being introduced at a rapid pace. One of the terms that is often used in the field of computer science is MAR, which stands for "Memory Address Register". In this article, we'll discuss what MAR stands for in computer science and how it is used.

What Is MAR?

MAR stands for Memory Address Register, and it is a type of register used in computer systems. The MAR is a special type of storage location on a computer processor that holds the address of a memory location. It is also known as a Memory Address Pointer. The MAR is used to keep track of memory addresses. It is usually set to the start address of a memory block, which is a group of bytes in memory. The MAR can then be incremented or decremented to move to different addresses in the memory block.

How Is MAR Used?

The MAR is an important part of the memory system in a computer. It is used in several different functions and operations, including:

Accessing data in a memory block: The MAR is used to keep track of the address of a memory block. It keeps track of the current address being accessed in the memory block, and it can also be used to move to different addresses in the memory block.
Storing instructions: The MAR can be used to store instructions in memory. This allows the computer to quickly access and execute instructions.
Managing memory: The MAR is used to manage memory, including allocating and deallocating memory blocks.

Conclusion

MAR stands for Memory Address Register and it is a type of register used in computer systems. It is used to keep track of memory addresses, store instructions, and manage memory. MAR is an important part of the memory system in a computer, and it is used in several different functions and operations.
