Write full forms of the following: o It manages and coordinates all of the computer’s units. o It reads instructions from memory, interprets them, and directs the computer’s operation. o It communicates with Input/Output devices to transfer data. o It neither processes nor stores data. Arithmetic Logic Unit This unit is divided into two subsections, namely, 9. What is BIOS? Describe its functions. 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. BIOS identifies, configures, tests, and connects computer hardware to the OS immediately after a computer is turned on. The combination of these steps is called the boot process. These tasks are each carried out by BIOS' four main functions: 1. Power-on self-test (POST). This tests the hardware of the computer before loading the OS. 2. Bootstrap loader . This locates the OS. 3. Software/drivers. This locates the software and drivers that interface with the OS once running. 4. Complementary metal-oxide-semiconductor (CMOS) setup. This is a configuration program that enables users to alter hardware and system settings. CMOS is the name of BIOS' non-volatile memory.
