Question 1 of 5
Which of the following is the most common input device used to input text, numbers, and instructions into the computer?
A
Mouse
B
Keyboard
C
Scanner
D
Printer
Why: The keyboard is identified as the most common input device for entering text, numbers, and instructions into a computer system. This is a fundamental component of computer hardware in the input stage of computer systems. Options: A-Mouse (pointing device), B-Keyboard (correct), C-Scanner (image input), D-Printer (output device).[1]
Question 2 of 5
First generation computers relied on which type of programming language, and what were their input and output methods?
Why: Machine language consists of binary code (0s and 1s) that the computer's processor could execute directly. Punched cards had holes representing data, fed into the computer for processing. Printouts were line printers producing paper output. This setup defined the rudimentary input-process-output model of computer systems.[1]
Question 3 of 5
Define a computer system and explain its basic components with examples.
Why: The definition encompasses both hardware and software, aligning with standard introductions to computer systems. Examples illustrate practical application. The structure follows exam-ready format with introduction, numbered points, example, and conclusion, exceeding 100 words for 3-4 mark level.
Question 4 of 5
What provides common services for computer programs using computer hardware and software resources? Give examples.
A
Application Software
B
System Software
C
Utility Software
D
Firmware
Why: System software acts as an intermediary between hardware and user applications, providing essential services like resource management, file handling, and hardware abstraction. Examples include Windows, Mac OS, and Linux. This is core to understanding operating systems in computer systems architecture. Option B matches this description.[2]
Question 5 of 5
What is the CPU in a computer system?
Why: The CPU definition includes key subcomponents and cycle, with example for clarity. Meets 50-80 word minimum for 1-2 marks, structured with bold terms and example.[5]
