The front-side bus is where your main memory lives.
MAR (Memory Address Register) holds the address of the memory location to be accessed or written to in the memory unit, whereas MDR (Memory Data Register) holds the actual data that is to be written to a memory location or data read from a memory location. MAR is used to specify the address, while MDR is used to temporarily store the data during memory operations.
Try this: #include <stdio.h> int main (void) { printf ("printf is at location %p\n", (void *)printf); printf ("main is at location %p\n", (void *)main); return 0; }
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
A variable typically consists of a name, a data type, a value, and a memory location where the value is stored. The name is used to reference the variable in the code, the data type defines the type of data the variable can hold, the value is the actual data stored in the variable, and the memory location is where the value is stored in the computer's memory.
A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.
Most modern computers use Random Access Memory for their main memory. However you don't need Random Access Memory, Sequential Access Memory is perfectly adequate and has been used in many computers in the past for main memory (it just happens to be much slower to access than Random Access Memory as you need to wait for the location to come around again).
NO.. it can be at any address in main memory.. But is should be at fixed location on hard disk because root directory needs to be loaded every time the pc boots.. thus it is kept at fixed location in disk to avoid the searching for it at every boot
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing.

difference between register and memory location
A newly created process is in main memory.
