A Brief History of Computers

The computer as we know it today had its start with a 19th century English math professor named Charles Babbage.
He made the Analytical Engine, and it was this design that the first frame of the computers of today is based on.

Computers can be categorised into three generations. Time and each gave us a new and improved computer or an improvement to the present computer.

It was known as the Atanasoff-Berry Computer (ABC). In 1943 a digital computer name the Colossus was built for the army. Other improvements continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) were assembled. It’s said that this computer weighed 30 tons, and had 18,000 vacuum tubes that were utilised for processing. If this computer was turned on for the first time lights dimmed in parts of Philadelphia. Computers of the time could only perform a single task, and they had no operating system.

Second generation: 1947 — 1962 – This generation of computers used transistors instead of vacuum tubes that were more reliable. In 1951 the first computer for industrial use was introduced to the general public; the Universal Automatic Computer (UNIVAC 1). Storage media like disk and tape were in use were printers for output.

Third generation: 1963 – current – The creation of integrated circuit brought us the next generation of computers. With this innovation, computers became smaller, stronger more reliable and they’re ready to run many different programs at the same time. In1980 Microsoft Disk Operating System (MS-Dos) was created, and in 1981 IBM introduced the personal computer (PC) for office and home use. Three decades after Apple gave us the Macintosh computer using its icon-driven interface and the 90s gave us Windows operating system.

As a consequence of the several improvements to the evolution of the computer, we’ve seen the machine being used in every area of life. It’s an efficient tool which will continue to experience new growth as time passes.
