Answer 1

There are so many types of computer memory first is tape backup
 2. hard drives
 3. usb
 4. ram (random access memory
 5. processor cache
 6. processor registors.

Answer 2

A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in computer where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address which varies from zero to memory size minus one. For example if computer has 64k words, then this memory unit has 64 * 1024=65536 memory locations. The address of these locations varies from 0 to 65535.

Memory is primarily of three types

Cache MemoryPrimary Memory/Main MemorySecondary Memory Cache Memory

Cache memory is a very high speed semiconductor memory which can speed up CPU. It acts as a buffer between the CPU and main memory. It is used to hold those parts of data and program which are most frequently used by CPU. The parts of data and programs are transferred from disk to cache memory by operating system, from where CPU can access them.

Advantages

The advantages of cache memory are as follows:

Cache memory is faster than main memory.It consumes less access time as compared to main memory.It stores the program that can be executed within a short period of time.It stores data for temporary use. Disadvantages

The disadvantages of cache memory are as follows:

Cache memory has limited capacity.It is very expensive.
