Computer Awareness Quiz with Answers

Computer Fundamentals and Generations

This part covers the basics. A computer takes input, processes it, stores it and gives output. The three main types are analog, digital and hybrid. The CPU is the brain of the computer and has three parts: the ALU (does maths and logic), the Control Unit (controls the flow) and Registers (small fast storage).

Exams love the generations of computers. The first generation used vacuum tubes, the second used transistors, the third used integrated circuits (IC), the fourth used microprocessors like the Intel 4004 chip from 1971, and the fifth is built around Artificial Intelligence. Remember the order and the main technology of each generation, because that single fact is asked often.

Hardware and Software

Hardware is the physical part you can touch, like the CPU, monitor, keyboard and hard disk. Software is the set of programs that tell the hardware what to do. Software has two main types: system software (like the operating system) and application software (like a browser or MS Word).

Know the difference between a compiler and an interpreter, and the idea of high level and low level languages. Questions also test file extensions, for example .docx for Word files, .xlsx for Excel and .exe for programs. These are easy marks if you have revised them.

Input, Output and Memory

Input devices send data into the computer, like the keyboard, mouse, scanner and microphone. Output devices show the result, like the monitor, printer and speakers. Some devices, like a touch screen, work as both input and output.

Memory is a big topic. RAM is volatile, which means it loses data when power is off, and it is used for temporary work. ROM is permanent and holds startup data like the BIOS. Cache is very fast memory close to the CPU. Storage devices like the hard disk, SSD and USB flash drive keep data even when the power is off. Learn the units too: 1 KB, 1 MB, 1 GB and 1 TB, each step is 1024 times the one before.

Operating Systems and MS Office

An operating system (OS) is the main system software that runs the computer and lets you use other programs. Common examples are Windows, Linux, macOS and Android. Know basic ideas like multitasking, booting and the difference between an OS and an application.

MS Office is asked a lot. MS Word is for documents, MS Excel for spreadsheets and calculations, and MS PowerPoint for slides. Shortcut keys come up often, for example Ctrl + C to copy, Ctrl + V to paste, Ctrl + Z to undo, Ctrl + S to save and Alt + F4 to close. In Excel, F2 edits a cell and F5 goes to a cell. A little revision here gives quick, sure marks.

Networking and the Internet

A computer network connects two or more computers so they can share data. Know the common types: LAN (small area), MAN (city size) and WAN (large area, like the internet). The internet is a worldwide network, and the World Wide Web (WWW) is the collection of web pages on it.

Learn key terms like IP address, ISP (Internet Service Provider), URL, HTTP and HTTPS, browser and search engine. Also understand basic ideas like email, the difference between the internet and an intranet, and what a server and a client mean. These terms appear in both the computer and general awareness sections.

Computer Security and Abbreviations

Security questions test the common threats. A virus is harmful code that disturbs how a computer works. A worm spreads by itself across a network. A Trojan horse looks safe but hides harmful software. Antivirus programs and firewalls protect the system, and a strong password and safe browsing help keep data safe.

Abbreviations are pure memory marks, so make a list and revise it. Common ones are CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), ALU (Arithmetic Logic Unit), OS (Operating System), IP (Internet Protocol), ISP (Internet Service Provider), HTTP, URL, GUI and LAN. Knowing these full forms can win you several easy questions in every exam.

Why it matters in the exam

Computer Awareness is a compulsory section in the Mains stage of most bank exams, including IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, IBPS RRB PO and IBPS RRB Clerk. In IBPS RRB Mains it carries about 40 questions, and across exams the marks usually range from about 10 to 40. The questions are factual and concept based, not long calculations, so it is treated as a high scoring and time saving section. A candidate who has revised the basics can finish this part quickly and use the saved time on Reasoning and Quant, which makes Computer Awareness a smart area to master.
