What is the difference between memory address and memory addressability?

A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.


What do you mean by MAR and MBR in computer organization?

MAR-memory address register used stored the address of the memory loaction MBR- memory buffer register is the actully data.


What is the purpose of the direct mapped cache tag in a computer system's memory management?

The purpose of the direct mapped cache tag in a computer system's memory management is to quickly determine if a requested memory address is stored in the cache memory. This helps improve the system's performance by reducing the time it takes to access data from the main memory.


How does the virtual address to physical address mapping work in computer systems?

In computer systems, the virtual address to physical address mapping works through a process called address translation. The operating system manages this mapping by using a page table, which stores the correspondence between virtual addresses used by programs and their corresponding physical memory locations. When a program accesses a virtual address, the operating system translates it to the corresponding physical address to retrieve the data stored in memory. This allows programs to efficiently access and manipulate data without needing to know the physical location of the memory.


What is an Address space?

An address space is a range of discrete addresses, all of the address locations available in a particular named subset of a computer's memory.

What is the meaning of computer memory?

Computer memory is what data the computer can keep stored. A computer can return to your favorite web address because it is stored in it's memory for example.


What is the role of an address when used in the context of computer memory?

In the context of computer memory, an address is used to access the computer's primary storage memory. These addresses consist of fixed-length digits displayed as unsigned integers.


What is meant by memory address?

A memory address is an identifier for a memory location, at which a computer program or a hardware device can store data and later retrieve it.

What does it means by relocatable address?

What is memory address register?

Whenever anything is stored in the memory of your computer (RAM) it is stored at a specific place. Each specific place in your memory has its address that can be used to tell computer programs to go to those addresses to perform actions on the object stored at that address. It is similar to how you have your house number.


What is the memory's addressibility?

HI I am Ahtarva,The addressibility is how many bits does that particular processor or micro-controller's architecture use to specify the address of a memory location in the memory. For example if someone say that addressibility is 8 bit then your memory address contains 8 bits and at maximum you have 2^8 different memory locations (or say memory addresses in your device). Here 2^8 is called Address space.

A computer has 64MB megabytes of memory Each word is 4 bytes How many bits are needed to address each single word in memory?

The memory address space is 64 MB, which means 226. However, each word is 4 bytes, which means that you have 224 words. This means you need log2 224 or 24 bits, to address each word.


Function of a MAR and MDR?

The Memory Address Register (MAR) holds the memory address that is currently being accessed or written to in the memory. The Memory Data Register (MDR) holds the data that is being read from or written to the memory at the address stored in the MAR. Together, the MAR and MDR facilitate the communication between the CPU and memory in a computer system.
