Computer MCQs

Computer MCQs are multiple-choice questions that test basic computer knowledge, from hardware parts and storage devices to networks, operating systems, keyboard shortcuts and common abbreviations. They help job-seekers and students preparing for public service, banking and clerical tests where a computer awareness section is standard. Every question on this page shows its correct answer instantly, so you can check yourself as you go.

About Computer MCQs

This collection covers the computer awareness syllabus that appears in most recruitment tests. Questions start with the fundamentals: the CPU as the brain of the computer, input and output devices, the parts inside a system unit, and the difference between primary and secondary memory. You will also find questions on the speed of different storage media, such as why magnetic tape is slower to access than a hard disk or RAM.

A large share of the questions deals with everyday software use. Expect items on function keys such as F12 for the Save As box, the Print Screen key for copying the screen, Alt+F4 for closing programs, and how files are organised into folders. Networking questions cover topologies, hubs, cables such as UTP, and web concepts including hyperlinks and Web 2.0 applications that let users create and share content.

Abbreviations form another important strand. Examiners like to ask what DMA, UTP, RAM, ROM or URL stand for, because one wrong word in a full form is easy to spot in a multiple-choice format. Computer MCQs matter because the topic is short, factual and scoring: candidates who revise it carefully can pick up marks quickly in tests where other sections are harder to predict.

Key facts to remember

  • The Central Processing Unit (CPU) is often called the brain of the computer.
  • RAM is volatile memory, so its contents are lost when power is switched off.
  • ROM stands for Read Only Memory and keeps its data without power.
  • One byte is made up of eight bits.
  • DMA stands for Direct Memory Access, letting devices transfer data without constant CPU involvement.
  • UTP stands for Unshielded Twisted Pair, a common network cable type.
  • A star topology connects every computer to a central hub or switch.
  • Printed output on paper is called hard copy, while screen output is soft copy.

How to prepare for Computer MCQs

  1. Make a one-page list of function keys and common shortcuts such as F5, F12, Ctrl+Z and Alt+F4, then test yourself daily.
  2. Learn full forms in groups, for example memory terms, network terms and internet terms, so similar abbreviations do not get mixed up.
  3. Rank storage devices by speed and capacity on paper, from registers and cache down to optical discs and magnetic tape.
  4. Draw the main network topologies (bus, star, ring, mesh) and note which device each one depends on.
  5. When a question uses the word except, read every option and eliminate the true statements before choosing the odd one out.

Frequently asked questions

What are the most important topics in Computer MCQs?

The most frequently tested areas are computer fundamentals (CPU, memory and storage), input and output devices, keyboard shortcuts and function keys, networking basics, internet terms and abbreviations. Questions on MS Office are also common, but MCQs360 keeps those in a separate MS Office category so you can practise them in depth.

Which exams ask Computer MCQs?

Computer awareness appears in many recruitment tests. In Pakistan it is common in PPSC, FPSC, NTS and banking tests. In India it features in SSC CGL, SSC CHSL, IBPS and SBI exams. In Bangladesh it appears in BCS preliminary and bank job exams.

How many Computer MCQs are on MCQs360?

MCQs360 has 715 Computer MCQs in this category, each with its correct answer shown instantly. The site is free and needs no sign-up, so you can work through the questions in short sessions and return whenever you want more practice.

How should I prepare for Computer MCQs?

Start with basic concepts such as hardware, memory and storage, then move to shortcuts and full forms, which reward regular repetition. Practise questions in batches of 20 to 30, note every mistake in a notebook and revise those notes before the exam. Using a computer while you study also helps shortcuts stick.

What is the difference between RAM and ROM?

RAM (Random Access Memory) is temporary working memory that holds programs and data while the computer is on, and it loses its contents when power is off. ROM (Read Only Memory) is non-volatile and stores permanent instructions, such as the firmware needed to start the computer.

Why is the CPU called the brain of the computer?

The CPU is called the brain because it carries out instructions and controls the other parts of the system. Its control unit directs the flow of data, and its arithmetic logic unit performs calculations and comparisons, much like the brain processes information and directs the body.
