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 a memory mapped register?
A memory mapped register is a register that has its specific address stored in a known memory location.
How does fetch decode cycle work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.
How does the Fetch Decode Execute work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.

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 memory address register of Intel 8085?
8 bits
What are the Functions of the memory buffer register?
In other words, MAR holds the memory location of data that needs to be accessed. When reading from memory, data addressed by MAR is fed into the MDR (memory data register) and then used by the CPU. When writing to memory, the CPU writes data from MDR to the memory location whose address is stored in MAR. The Memory Address Register is half of a minimal interface between a microprogram and computer storage. The other half is a memory data register. Far more complex memory interfaces exist, but this is the least that can work.
How would you use indirect address?
An indirect address is an address contained in a register or memory location, instead of in the instruction itself. In the 8085, the most common form is to load or calculate an address in the HL register, and then access the memory pointed to by HL using the M register designation, such as MOV A,M.
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.
What is address register?
this is the memory that hold data temperaly and can be used in future
What is the specific purpose of hl register?
HL is a general purpose 16 bit register. It is also the address in memory of the M register.
