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.

What is stored in main memory?
Memory is used for the purpose of running programs, for example, your text editor. The text editor stores the file you are editing as what is known as a 'buffer' in your memory instead of modifying the file in-place. This is what makes undo/redo possible.
Is cache memory faster than CPU registers?
what is the difference between cache & register ? Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory. The register is a small set of data holding places that are part of a computer processor . A register may hold a computer instruction , a storage address, or any kind of data (such as a bit ..."
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
What is main memory in computer architecture?
main memory is RAM.The words Memory,Buffer,Cache are all refers Ram. Which is Nearly 11,000 times faster than secondary memory (Hard Disk) in Random Access.
What component has the fastest speed on computer?
Register. The memory hierarchy in the decreasing order of speeds: 1. Register 2. Cache 3. Main memory 4. Disks 5. Auxiliary memory
What is the purpose of a ram chips?
it's main purpose is to work with the temporary memory.
Main memory is located on the CPU chip?
The only memory located on a computers CPU chip is called the cache.... typically about 1-8MB in size it acts as a rapid access 'buffer' for immediate actions.The main memory is usually termed the RAM and sit's nexto the CentralProcessorUnit - connected by the FrontSideBus (board circuitry), size.... well depending on age anything from a few MB to 16GB (dependant on a number of factors).Actually, the term "main memory" is reserved for the primary location where active work is stored. In modern computers, "main memory" consists of DRAM chips mounted somewhere near the CPU. Thus, "main memory" is never on chip. The reason for this is cost - providing memory inside the CPU is hideously expensive, there is a limit to how much can be put there, and the amount can never change. Off-chip main memory allows very significant cost savings, and allows the amount of memory to be adjusted freely.There are generally TWO types of memory that are located on-chip, however. Cache memory (which can come in various "levels", describing how far away from the main CPU each memory bank is) is used to keep copies of data from the main memory in a location that is "closer" to the CPU, and thus faster to access and use. Registers are memory located directly inside the CPU's execution units - think of them as scratch space where the CPU can temporarily store small amounts of data while it does a calculation. For instance, if a CPU is asked to do: A+B=C, it will have to load A into a register, then load B into a register, then do the calculation, saving the result into a register, then finally load the "results" register value back into C.
What is the main purpose of a core dump action?
The main purpose of a core dump action is to record the content of the process and also the useful information related to it, for example the processor register's value.
