This article aims to delve into the essence of a computer, Its past, and Its various classifications.


What is computer?


Defining a computer: It is an electronic apparatus that swiftly manages data and carries out computations with remarkable efficiency. A combination of both physical and digital elements function cohesively to manage and retain information. A computer has the ability to carry out diverse tasks including communication, storage, processing and retrieval of data.



History of computer

The origin story of computers takes us back to the mid-1800s, when the inaugural mechanical calculator was created. In the early 1800s, the creation of the first computer that was programmable is attributed to Charles Babbage, a mathematician from England. Electronic computers were not invented until the middle of the 20th century. In 1946, the Electronic Numerical Integrator and Computer ((ENIAC)) was developed, marking the advent of the first electronic computing device. Ever since, computers have kept progressing, becoming speedier, compact, and less expensive.
