1. Write full forms of the following:
o Arithmetic Logic Unit Memory or Storage Unit This unit has the capability of storing instructions, data, and intermediate results. When necessary, this unit sends data to other computer units. It is also referred to as an internal storage unit, main memory, primary storage, or Random Access Memory (RAM). Its size has an impact on its speed, power, and capability. In a computer, there are two types of memories: primary memory and secondary memory. The memory unit’s functions are as follows: o It saves all of the data and instructions needed for processing. o It saves intermediate processing results. o It saves the final results of processing before they are sent to an output device. o The main memory is where all inputs and outputs are routed. The Control Unit This unit manages the operations of all computer components but does not perform any actual data processing. To function properly, all CPU components must be synchronized. The control unit performs this function at a rate determined by the clock speed and is in charge of directing the operations of the other units through the use of timing signals that run throughout the CPU. This unit’s functions are as follows: o It is in charge of controlling the transfer of data and instructions among the various components of a computer.
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.
