COMPUTER FUNDAMENTALS

Detailed explanation-1: -The BIOS (sometimes called ROM BIOS) is always the first program that executes when a computer is powered up. Here’s what happens during the boot process (see steps in diagram below): Power is turned on. The CPU hands control over to the BIOS.

Detailed explanation-2: -ROM contains the programming that allows a computer to start up or regenerate each time it is turned on. ROM also performs large input/output (I/O) tasks and protects programs or software instructions. Once data is written on a ROM chip, it cannot be removed.

Detailed explanation-3: -ROM (read-only memory) is a non-volatile memory type. This means it receives data and permanently writes it on a chip, and it lasts even after you turn off your computer. The data is coded to not be overwritten, so it’s used for things like your printer software or your startup programs.

Detailed explanation-4: -ROM is a read-only memory and RAM is read-write memory but both are random access memory. Concept: EPROM and EEPROM is a type of ROM. Data in ROM can be accessed randomly and hence EPROM and EEPROM are random access memory.

Detailed explanation-5: -A simple example of ROM is the cartridge used in video game consoles that allows the system to run many games. The data which is stored permanently on personal computers and other electronic devices like smartphones, tablets, TV, AC, etc. is also an example of ROM.
