Computer Trivia Quiz Questions

Explanation
KB is lesser than MB because KB stands for kilobyte, which is a unit of digital information that is smaller than a megabyte (MB). In the binary system, 1 kilobyte is equal to 1024 bytes, while 1 megabyte is equal to 1024 kilobytes. Therefore, KB is the correct answer as it is the only option that is smaller than MB.

Explanation
The correct answer is "Central Process Unit." CPU stands for Central Processing Unit, which is the main component of a computer that carries out instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. It is often referred to as the "brain" of the computer as it performs all the major calculations and operations necessary for the computer to function.

Explanation
A keyboard is considered an input device because it allows users to input data and commands into a computer system. It consists of a set of keys that are used to type letters, numbers, and other characters. The input from the keyboard is then processed by the computer and displayed on the monitor or used for various tasks.

Explanation
MS Paint is the correct answer because it is a program specifically designed for drawing and creating simple diagrams and illustrations. MS DOS is an operating system, not a drawing program. MS Excel is a spreadsheet program, not a drawing program. "None of these" is not the correct answer because MS Paint is a widely used program for drawing diagrams.

Explanation
MS Excel is the correct answer because it is a program specifically designed for calculations and data analysis. It provides various mathematical and statistical functions, as well as the ability to create formulas and perform complex calculations. MS PowerPoint is a presentation software, MS Paint is a basic image editing program, and "None of these" does not accurately represent a program used for calculations.

Explanation
The statement "The keyboard contains more than 40 buttons" is true because a standard keyboard typically has more than 40 buttons. Keyboards usually have a combination of alphanumeric keys, function keys, control keys, and special keys, which collectively add up to more than 40 buttons.

Therefore, the mouse is indeed an input device.

Explanation
Charles Babbage is considered the father of the computer because he designed and conceptualized the first mechanical computer, known as the Analytical Engine, in the 19th century. Although the Analytical Engine was never fully built during Babbage's lifetime, his ideas and designs laid the foundation for modern computing. Babbage's contributions to the field of computer science, including his development of the concept of a programmable machine, make him a significant figure in the history of computers. Therefore, the statement that Charles Babbage is the father of the computer is true.
