Detailed explanation-1: -BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
Detailed explanation-2: -While the ROM chip is commonly used in the startup operations for the computer, the RAM chip is often used in the recurrent tasks of the computer once the OS has been configured.
Detailed explanation-3: -A chipset is a group of interdependent motherboard chips or integrated circuits that control the flow of data and instructions between the central processing unit (CPU) or microprocessor and external devices. A chipset controls external buses, memory cache and some peripherals.
Detailed explanation-4: -1. Short for Basic Input/Output System, the BIOS (pronounced bye-oss) is a ROM chip found on motherboards that lets you access and set up your computer system at the most basic level. The picture below is an example of what a BIOS chip may look like on a computer motherboard.
Detailed explanation-5: -ROM is located on a BIOS chip which is plugged into the motherboard. ROM is a type of memory circuitry that holds the computer’s startup routine. The ROM BIOS tells the computer how to access the hard disk, find the operating system, and load it into RAM.
