Basic Computer MCQs — Practice & Prepare

41

Which of the following is first generation computer?

✅ Correct answer: EDSAC EDSAC (1949) was one of the earliest first-generation, vacuum-tube-based stored-program computers.
42

Signals can be analog or digital and a computer that processes the both type of signals is known as

✅ Correct answer: Hybrid Computer A hybrid computer is designed to process both analog and digital signals, combining the strengths of both computer types.
43

Number crunchier is the informal name for

✅ Correct answer: Super computer Because of their enormous raw computing power for numerical calculations, supercomputers are informally nicknamed 'number crunchers.'
44

The processing speed of first generation computers was

✅ Correct answer: milliseconds First-generation, vacuum-tube-based computers operated at speeds measured in milliseconds — far slower than the microsecond and nanosecond speeds of later generations.
45

Most important advantage of an IC is its.

✅ Correct answer: Extremely high reliability The biggest advantage of an Integrated Circuit (IC) is its extremely high reliability, since it has far fewer external connections and moving parts to fail.
46

The word Abacus is derived from Abax, a word from

✅ Correct answer: Latin language The word 'Abacus' is believed to derive from 'abax,' a Latin word (itself possibly borrowed from Greek) referring to a flat surface or tablet used for counting.
47

The term ‘computer’ is derived from

✅ Correct answer: Latin language The word 'computer' comes from the Latin verb 'computare,' meaning 'to calculate' or 'to reckon.'
48

Who is the inventor of ABC Computer?

✅ Correct answer: Both of above John Vincent Atanasoff and his graduate student Clifford Berry jointly built the ABC (Atanasoff-Berry Computer) at Iowa State University.
49

What was the first computer to perform all calculation using electronics rather than wheels, ratchets, or mechanical switches?

✅ Correct answer: ABC The Atanasoff-Berry Computer (ABC), built 1937-1942, was the first machine to do all its calculations electronically rather than with mechanical wheels or ratchets.
50

The earliest calculating devices are

✅ Correct answer: Abacus The abacus, dating back thousands of years, is recognized as the earliest known calculating device used by humans.
51

Who invented Integrated Circuits?

✅ Correct answer: Both of above Jack Kilby (Texas Instruments) and Robert Noyce (Fairchild/Intel) independently developed the integrated circuit around 1958-1959, and both are credited as its inventors.
52

An error in software or hardware is called a bug. What is the alternative computer jargon for it?

✅ Correct answer: Glitch In computer jargon, an error or fault is often informally called a 'glitch,' in addition to the more formal term 'bug.'
53

An integrated circuit is

✅ Correct answer: Fabricated on a tiny silicon chip An integrated circuit (IC) packs many transistors, resistors, and other components onto a single tiny piece of silicon, making circuits smaller, cheaper, and faster.
54

Abacus was the first

✅ Correct answer: mechanical calculator The abacus, used since ancient times for counting and arithmetic with beads on rods, is considered the earliest mechanical calculating device.
55

Which of the following machine was not invented by Charles Babbage?

✅ Correct answer: Tabulating Machine Charles Babbage designed the Difference Engine and the Analytical Engine, but the Tabulating Machine was instead invented by Herman Hollerith.
