2. Elaborate the functions of the following:
Control unit – i. A control unit can be described as a sort of circuitry that supervises and controls the path of information that runs over the processor and organizes the various activities of those units that lie inside it. ii. It carries out many tasks such as decoding, fetching, handling the execution and finally storing the results. iii. It controls the execution of instructions in a sequential order. iv. It guides the flow of data through the different parts of the computer. v. It may manage the translation of instructions (not data) to micro-instructions and manage scheduling the micro-instructions between the various execution units. vi. It regulates the time controls of the processor. vii. It sends and receives control signals from various peripheral devices viii. The control unit implements the instruction set of the CPU. * A control unit is a major computer part which helps in the functioning of the central processing unit and in turn runs the whole computer.
“Operating system; The operating system provides for several other functions including: * Booting the computer - The process of starting or restarting the computer is known as booting. A cold boot is when you turn on a computer that has been turned off completely. A warm boot is the process of using the operating system to restart the computer.
* Performs basic computer tasks - The operating system performs basic computer tasks,
