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)

Thanks!
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second 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.

A newly created process is in main memory.
By "main memory" I assume you mean Primary Storage. This would be your RAM (Randon Access Memory)
False. The main or primary memory is the Random Access Memory that is both readable and writable.
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..
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
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. Some examples of auxiliary memory would be disks, external hard drives, USB drives, etc.
main memory is fast ans you cant lose any parts to it
the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU. the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU.
