About Computer Hardware and Devices MCQs

Questions on the processor cover the central processing unit and its parts: the control unit, the arithmetic logic unit and registers such as the program counter. Memory and start-up questions ask where BIOS settings are stored and how the system unit is organised. Integrated circuits and the uses of microprocessors also appear. Device questions cover input devices such as keyboards, scanners and digitisers, and output devices such as monitors and printers. Keyboard questions ask about function keys, modifier keys and the typical number of keys, while display questions cover pixels, CRT technology and resolutions such as VGA and 4K. Printer questions include dot matrix printing and how output quality is measured.

Key facts to remember

The CPU consists mainly of the control unit and the arithmetic logic unit, supported by registers.
The program counter holds the memory address of the next instruction to be executed.
BIOS settings are stored in CMOS memory, kept powered by a small battery on the motherboard.
Printer resolution is measured in dots per inch (dpi).
The VGA standard has a resolution of 640 x 480 pixels.
4K Ultra HD television resolution is 3840 x 2160 pixels.

How to prepare for Computer Hardware and Devices MCQs

Draw a simple block diagram of input, processing, storage and output and place each device in it.
Learn the parts of the CPU and the job of each register, since examiners like the control unit and ALU.
Memorise common display resolutions and keyboard key groups as a short list.
Separate devices that look similar but do different jobs, such as scanners and digitisers or plotters and printers.

Frequently asked questions

Which exams ask computer hardware MCQs?

Hardware questions appear in the computer sections of PPSC, FPSC, NTS and KPPSC tests in Pakistan, in SSC, IBPS and SBI exams in India, and in BCS and bank recruitment tests in Bangladesh, as well as in many IT and teaching posts.

What are the main parts of a CPU?

The CPU has a control unit, which directs the operation of the processor, and an arithmetic logic unit, which performs calculations and comparisons. Registers inside the CPU hold small amounts of data and addresses, such as the program counter, which points to the next instruction.

What is the difference between input and output devices?

Input devices, such as keyboards, mice and scanners, send data and instructions into the computer. Output devices, such as monitors, printers and speakers, present processed results to the user. Some devices, such as touchscreens, do both jobs.
