The design of laptop was proposed by......

Dynabook

     The invention of Laptop came from idea to develop a portable computer. Mr.Alan kay of XEROX Palo Alto Research Centre firstly proposed about the notebook-sized portable computer which should be available for everyone and named that portable computer as Dynabook. At  that time only he envisioned Dynabook with wireless capabilities.

The first PC (IBM compatible) computer

On April 7, 1953 IBM publicly introduced the 701, its first electric computer and first mass produced computer. Later IBM introduced its first personal computer called the IBM PC in 1981. The computer was code named and still sometimes referred to as the Acorn and had a 8088 processor, 16 KB of memory, which was expandable to 256 and utilizing MS-DOS.

The first computer company

The first computer company was the Electronic Controls a series of mainframe computers under the UNIVAC name Company and was founded in 1949 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer. The company was later renamed to EMCC or Eckert-Mauchly Computer Corporation and released.

The first stored program computer

The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game.

The first digital computer.....

Short for Atanasoff-Berry Computer, the ABC started being developed by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be developed until 1942 at the Iowa State College (now Iowa State University). On October 19, 1973, the US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge ruled that the ABC computer was the first digital computer, many still consider the ENIAC to be the first digital computer because it was fully functional.

1.Who is the father of Modern Computer....?

 We all know that The Charles Babbage, an English mathematician was the father of computer but he invented two engines, 

(i) Difference engine and

(ii) Analytical Engine.

  from which he gave a basic idea about computation only.....

The person who developed the first electronic-digital computer was John Atanasoff.

Professor John Atanasoff and graduate student Clifford Berry built the world's first electronic-digital computer at Iowa State University between 1939 and 1942. The Atanasoff-Berry Computer represented several innovations in computing, including a binary system of arithmetic, parallel processing, regenerative memory, and a separation of memory and computing functions.

Presper Eckert and John Mauchly were the first to patent a digital computing device, the ENIAC computer. A patent infringement case (Sperry Rand Vs. Honeywell, 1973) voided the ENIAC patent as a derivative of John Atanasoff's invention. Atanasoff was quite generous in stating, "there is enough credit for everyone in the invention and development of the electronic computer." Eckert and Mauchly received most of the credit for inventing the first electronic-digital computer. Historians now say that the Atanasoff-Berry computer was the first.
