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.
What is fixed partition main memory management technique in operating systems?
A partitioned memory management technique is when the operating system loads more than one application program into memory at the same time, they share memory space and cpu time. The main memory (which is the volatile memory where active programs and data are held during use), is divided into partitions that different processes that are running can fit into. The partitions sizes can either be fixed, or they can change to encompass the size of the process that is to be run. So, a fixed partition main memory management technique is when the main memory is divided into partitions that do not change based on the size of the process, they are a fixed size. And a process is loaded into a partition big enough to hold it.
What is the difference between Page and Frame?
Ø In a paging system, programs and data stored on disk are divided into equal, fixed sized blocks called pages, and main memory is divided into blocks of the same size called frames. Exactly one page can fit in one frame. Physical memory is divided into parts called FRAME and logical memory is divided into parts called PAGE.

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.

Is newly created process is in main memory or in secondary memory?
A newly created process is in main memory.
What type of memory is called the main memory?
By "main memory" I assume you mean Primary Storage. This would be your RAM (Randon Access Memory)
Read-only memory is also referred to as main memory or primary memory?
False. The main or primary memory is the Random Access Memory that is both readable and writable.
What is main memory?
Main memory:Main memory is the computer's internal memory. It is an extension of the Central Processing Unit (CPU).Its function is controlled by the Control Unit (CU) that sends READ or WRITE signal for the appropriate memory location. Main memory accepts data and instructions from the input unit, exchanges them with other parts of the CPU for processing. It stores those instructions and data, which are currently being used by the CPU or awaiting for immediate execution.Semiconductor memories are the widely used forms of main storage. The capacity of a storage device is normally expressed in bytes, characters or bits. Computer's main memory is further divided into random access memory (RAM) and read only memory (ROM)By Professor MUHAMMAD SHOAIB BILALEmail: Shoaibbilal64@yahoo.comThanks!
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
What are interleaved memory organization?
interleaved memory organization is divided into memory banks.in sequential address space......
Is cache memory is the main memory of cmputer system?
NO...The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.Thus Cache memory is not main memory of computer system.--- form Wiki
