1) What is Computer Memory? How many types are there?

=> Technically any device that stores data or instructions on the PC can be called memory, including the Hard Disk, Floppy Disk, ROM, RAM and cache. However commonly referred to as memory on the PC is its primary memory, storage, which is also known as system memory, temporary storage or RAM. With the exception of ROM, the other forms of storages (Hard Disk, Floppy Disk, CD-ROM and the like) are known as secondary storage.


Classification of Computer Memory:

1) Primary Memory:-
The memory on the motherboard of the Computer is called the primary memory. This is also called the main memory or on-line memory because it is directly available to the processor.
This primary memory can be further divided by the following types:-

a) Random Access Memory (RAM):-
Ram or Random Access Memory, is used in the PC for its primary memory. RAM is where all active programs and data are stored so that they can be readily available and easily accessed by the CPU and other components of the CPU.

b) Read only Memory (ROM):-
Data stored on read only memory or ROM can’t be changed. ROM also has the added feature of being nonvolatile, which means that it can keep its contents even without a power supply. This makes it ideal for storing the PC’s startup instructions and system BIOs (Basic Input/output system).

2) Secondary Memory:-
Secondary Memory is actually used to store program or data permanently. This memory is not on Motherboard. It is connected via cable or connector. It is non-volatile memory. This is also called auxiliary or permanent memory. Example: Hard Disk Drive, Floppy Disk Drive, CD/DVD, Pen Drive etc.
