Computer

MCQs about Computer Basics cover the topics related to software, hardware, input-output devices, CPU, RAM, ROM, and secondary storage, etc.

The greatest scientists of their era, Abu Jaffar Muhammad Ibn Musa Al-Khawarizmi (780-850), Alan Mathison Turing (1912-1954), and John Von Neuman (1903-1957) took part in the invention of computers. A mathematician and a scientist (of France) Blaise Pascal developed the first mechanical computing machine called “Paccaline” in 1642. Leibnitz invented the machine and named it the “Multiplier Wheel” to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The “MUltiplier Wheel” machine was further modified in 1971.

In 1833 Charles Babbage invented the “Analytical Engine” which was the first programmable computer. The basic units of the Analytical Engine were (I) A storage, (ii) A mill, and (iii) A control unit. Mauchly and J.P. Ekert at Moor School of Engineering in the USA gave the name to the computer as “Electronic Numerical Integrator and Calculator (ENIAC)”.

All the input devices send information to a computer system for further processing, while output devices reproduce or display the results (outputs) of that processing. Input devices only allow for data input to a computer and output devices only receive the output from another device. Note that all the devices are called the hardware of a computer system.

Examples of Input Output Devices are:

Computer Output Devices:

• Monitor
• Printer
• Audio Speakers
