Question

what is the difference between RAM and ROM​

Answer 1

Answer:

★ RAM (Random Access Memory) -

• RAM is used to store data temporarily.

• The RAM is used by computer to temporarily store information

• If you are working with a notepad document and didn't save the file, if you switch to another application. When you open the notepad, the data is still there. This is because the document is present in RAM.

• However, if the computer is switched off and you don't save the document you will lose it, that is why RAM is known as temporary memory.

• It is also called as Read/Write memory.

★ ROM (Read Only Memory) -

• Computer manufacturers store a special set of instructions in the computer memory in order to make the computer work. These instructions are stored in ROM.

• ROM comprises of a software called the BIOS (Basic ROM Input/Output System).

• When a computer is switched on the BIOS helps to load the operating system.

• The instructions stored in ROM remain in the computer memory even if the computer is switched off. Hence, this memory is also called the permanent memory or non- volatile memory.

• Unlike RAM, it is not possible to write information in ROM. You can only read information from ROM.
