1List the main components of a computer hardware according to Von Neumann.very likelyModule 2· Tap for answer
system unit, motherboard, CPU, ports, input/output devices, primary memory, secondary storage, communication devices
Page 31 (printed 21)“Von Neumann's architecture described the digital-based computer hardware as a system comprising the following major main components, namely; system unit, motherboard, CPU, ports, input/output devices, primary memory, secondary storage devices, communication devices”
2Explain the function of the CPU.very likelyModule 2· Tap for answer
Carries out execution of instructions, data manipulation, and controls other parts for smooth running.
Page 35 (printed 25)“The CPU carries out the execution of computer instructions or programs and data manipulation. It also controls the functions of other parts of the computer to enable the smooth running of the entire computer system.”
3Define RAM and its key characteristic.very likelyModule 2· Tap for answer
Main memory holding data/instructions only during execution; data lost when power off.
Page 38 (printed 28)“Random Access Memory (RAM) is the main memory or primary storage that has the capability of holding the loaded data, instructions, operating system, and all running applications, processes, and other programs only during execution, that is, when the computer system is running and powered by electricity.”
4What is a computer?very likelyModule 1· Tap for answer
An electronic device that can receive data, process it, and produce results.
Page 12 (printed 2)“A computer can be described as an electronic device that can receive data, process the data, and produce the result as the outcome.”
5Define a microchip.very likelyModule 4· Tap for answer
A set of electronic circuits with millions of miniatured transistors on a silicon slab.
Page 66 (printed 56)“A microchip is a set of electronic circuits with millions of miniatured transistors mounted on a small flat piece of silicon slab.”
