Detailed explanation-1: -The CPU starts and fetches instructions into RAM from the BIOS, which is stored in the ROM. The BIOS starts the monitor and keyboard, and does some basic checks to make sure the computer is working properly. For example, it will look for the RAM. The BIOS then starts the boot sequence.
Detailed explanation-2: -Read-only memory, or ROM, is a type of computer storage containing non-volatile, permanent data that, normally, can only be read, not written to. ROM contains the programming that allows a computer to start up or regenerate each time it is turned on.
Detailed explanation-3: -A ROM stores such instructions that are required to start a computer. This operation is referred to as bootstrap. ROM chips are not only used in the computer but also in other electronic items like washing machine and microwave oven.
Detailed explanation-4: -Traditionally, the BIOS (the computer boot up instruction set) was always stored in ROM because it is non-volatile. However, flash memory (which is also non-volatile, but not read-only) is now often used for the BIOS so that changes to the instructions can be made.
Detailed explanation-5: -The memory is the space used for keeping all the data, and operations happening in the system. ROM belongs to the memory group of the system. ROM has the ability to access the data stored on them even after the power to the system is gone. More items •03-Aug-2019
