1List the main components of a computer hardware according to Von Neumann architecture.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 hardware functions
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 Random Access Memory (RAM).very likelyModule 2· Tap for answer
main memory holding data, instructions and running programs only during execution while powered
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.”
4Define operating system.very likelyModule 1· Tap for answer
OS interfaces between system hardware, application software, and the users.
Page 23 (printed 13)“Operating system software is software that interfaces between system hardware, application software, and the users.”
5What is the computer system clock and its effect on CPU speed?very likelyModule 4· Tap for answer
An electrical pulse generator; more pulses per cycle makes the CPU work faster.
Page 62 (printed 52)“The computer system clock is an electrical pulse generator that sends out a pulse of electricity at regular intervals.”
