Question

In which year the first digital electronic computer was built?
A. 1940
B. 1945
C. 1946
D. 1948

Answer 1

Hint:The electronic computerized PC was imagined a little more than forty years prior, introducing a progression of mechanical changes which must be contrasted with the Industrial Revolution in their degree, extent, and effect.

Complete answer:
The first digital electronic computer was built in year of 1946. The Atanasoff-Berry Computer (ABC) was the world first electronic advanced PC. John Vincent Atanasoff, a previous Iowa State educator of material science and arithmetic, and Clifford Berry, a previous material science graduate understudy and electrical designing undergrad, fabricated the PC at Iowa State University from 1937 to 1942.

In the venture proposition, Atanasoff had wanted to recruit an electrical designing understudy to help him in building the PC. He at that point met an electrical designing educator, Harold W. Anderson while strolling across grounds. Atanasoff disclosed to Anderson the sort of understudy he needed and
Anderson answered,I have your man: Clifford Berry. The ABC looked in no way like the present PCs: It was the size of a major work area, weighed 750 pounds, and included pivoting drums for memory, shining vacuum tubes, and a read/compose framework that recorded numbers by singing blemishes on cards.

Yet, the machine likewise was the first to utilize a few developments that are as yet a piece of the present PCs: a paired arrangement of number juggling, separate memory and figuring capacities, regenerative memory, equal handling, electronic enhancers as on-off switches, circuits for coherent expansion and deduction, timed control of electronic tasks, and a particular plan.

Hence correct answer is the option (C).

Note: Before we had PC architects or PC researchers to plan and construct PCs, analysts from numerous orders, including material science, arithmetic, and electrical designing, attempted to build up the main processing machines.
