MCQs Computer

These MCQs about computer test covers various topics related to the Basics of Computer Studies.

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’s 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 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 name to the computer as “Electronic Numerical Integrator and Calculator (ENIAC)”.

MCQs Computer Basics

In 1944 John Neumann gave the idea to store programs electronically inside the computer. It was the final breakthrough in computers. From 1944 and onward, electronic computes are divided into five generations. First-generation (1942-1959): these computers were very large in size, slow in speed, unreliable, and difficult to maintain. Second-generation (1959-1965): these computers were small in size but fast in speed. Third-generation (1965-1970): these computers were small in size but very fast in speed. Fourth-generation (1970-1980): in these computers microprocessors were used. Fifth-generation (1980-Owward): these computers are very very fast and can perform millions of instructions per second. There is the ability of reasoning and draw inferences like human beings.
