COMPUTER FUNDAMENTALS

Detailed explanation-1: -Primary memory is the computer’s main memory and stores data temporarily. Secondary memory is external memory and saves data permanently. Data stored in primary memory can be directly accessed by the CPU, which cannot be accessed in secondary memory.

Detailed explanation-2: -There are technically two types of computer memory: primary and secondary. The term memory is used as a synonym for primary memory or as an abbreviation for a specific type of primary memory called random access memory (RAM).

Detailed explanation-3: -The difference between primary and secondary memory is that Primary memory is the main memory of the device/ computer where the processing data exist and the secondary memory of a device/ computer is an auxiliary memory that stores the data permanently.

Detailed explanation-4: -The two main types of primary storage are ROM, which is non-volatile, and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off.

Detailed explanation-5: -Primary memory is volatile, while secondary memory is non-volatile. Primary memory is stored on semiconductor chips, while secondary memory is stored on external hardware devices. Primary memory is classified into cache and random access memory, while secondary memory has no such categories. Primary memory is faster.
