Detailed explanation-1: -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-2: -Primary memory is the internal memory of a computer system. It stores and retrieves data, instructions, and information. The CPU directly and randomly accesses primary memory; hence primary memory is also referred to as Random Access Memory or RAM.
Detailed explanation-3: -Secondary memory is also known as External memory or Auxiliary memory. Examples: RAM, ROM, Cache memory, PROM, EPROM, Registers, etc. Examples: Hard Disk, Floppy Disk, Magnetic Tapes, etc.
Detailed explanation-4: -Primary storage provides fast access to the CPU. That allows active programs to deliver optimal performance to the end-user. Speed and usefulness aside, the loss of power means the loss of data. That makes RAM a short-term storage solution.
Detailed explanation-5: -Hint:Our machine contains both RAM, which stands for random access memory, and ROM, which stands for read-only memory. RAM is a volatile memory that holds the files we’re operating on temporarily. The ROM is a non-volatile memory that holds our computer’s instructions indefinitely.
