What is the location of the FSB?
The front-side bus is where your main memory lives.
Where the printf statements are stored in memory?
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; }
Is cache memory is main or sec memory?
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
Physical address and logical address?
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.
Is the root directory of a disk should be placed at a fixed address in main memory?
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
Why do we need computer RAM?
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).
What is a difference between register and a memory location?
difference between register and memory location
What is the difference between main and auxiliary memory?
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.

Write short notes on different types of RAM?
Basically main memory is referred as Random Access Memory (RAM) because it is possible to randomly select and use any location of this memory to direct store and retrieve data and instructions.
When does the operating system creates virtual memory?
when the actual memory is full
Is newly created process is in main memory or in secondary memory?
A newly created process is in main memory.
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.
