Computer Fundamentals Questions with Solutions
Computer fundamentals covers the basic concepts every computer awareness section starts with: what a computer is, its characteristics (speed, accuracy, storage, automation), the history and generations of computers, types of computers (supercomputers, mainframes, minicomputers and microcomputers), and the basic functional units of input, processing, storage and output. Exam questions are mostly factual and quick to answer if you know the facts. Common questions include who is known as the father of computers (Charles Babbage), which technology was used in each generation (vacuum tubes, transistors, integrated circuits, microprocessors), the full forms of common abbreviations, and the difference between hardware, software and firmware. Making a short revision sheet of generations and abbreviations is the most efficient way to prepare. Practise the computer fundamentals questions below. Each answer includes a short explanation.
