Explain volatile memory and non volatile memory?
Volatile memory means when the system power is off the data is lost.Where as non volatile means the data is not lost when the system is powered off.

Draw the block diagram of ram and explain its operation?
Memory is technically any form of electronic storage. Personal computer system have a hierarchical memory structure consisting of auxiliary memory (disks), main memory (DRAM) and cache memory (SRAM). A design objective of computer system architects is to have the memory hierarchy work as through it were entirely comprised of the fastest memory type in the system.
What is the advantage of storing information in primary memory rather than secondary memory?
The details stored on the RAM will only be gone when the system is spoilt but the ROM, the CD or flash drive can get lost and vital details will be lost. Yomi
Explain the components of operating system?
There are several components of the operating system which facilitate the proper functioning of a computer system. The main component if the kernel which is broken down into CPU, memory and other devices.
What is Chache memory and how can it be used?
The chache memory is a memory that mostly resides inside the processor's chip, this will make the processing a lot faster because the memory (chache) is nearer that the main memory of the system. btw, chache is a mispelling of cache, go to http://keywordspeak.com/?p=1234 for more details.

How paging is used to manage memory explain with examlpe?
Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory, thereby reducing fragmentation. In this system, the process's virtual memory is divided into fixed-size blocks called pages, which correspond to blocks of physical memory called frames. For example, if a process requires 8 pages and the system has 4 frames, the operating system can load 4 pages into memory while keeping the rest on disk until needed. This allows for efficient use of memory, as pages can be swapped in and out as required, facilitating multitasking and efficient memory utilization.
Explain the concept of virtual memory and why it is needed?
In order to free up space in memory, an operating system with a virtual memory capability transfers data that is not immediately needed from memory to the HDD; when that data is needed again, it is copied back into memory. That is, when all of the RAM is being used (e.g., if there are many programs open simultaneously or if one very large program is in use), a computer with virtual memory enabled will swap data to the HDD and back to memory as needed, thus, in effect, increasing the total system memory.
