C
o perform a soft processor
D
located in the computer’s read-only memory (ROM), that is built
E
designed to perform maintenance service of character
Explanation: 

Detailed explanation-1: -A computer’s basic input/output system (BIOS) is a program that’s stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware. The BIOS (sometimes called ROM BIOS) is always the first program that executes when a computer is powered up.

Detailed explanation-2: -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-3: -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. Almost every computer incorporates a small amount of ROM that contains the start-up firmware. This boot firmware is called the basic input/output system (BIOS).

Detailed explanation-4: -BIOS, or Basic Input/Output System, is software stored on a small memory chip, also known as firmware. BIOS is found on the motherboard, and it is the very first software to run after a computer starts.

Detailed explanation-5: -The basic input/output system (BIOS) is the part of an operating system that links the specific hardware devices to the software. It obtains the buffers required to send information from a program to the hardware/desktop receiving the information.
