Well, it isn't easy. The first computer can be described as a Chinese abacus, lol I am serious.
The word "computer" was first used
The word "computer" was first recorded as being used in 1613 and was originally was used to describe a person who performed calculations or computations. The definition of a computer remained the same until the end of the 19th century when it began referring to a machine that performed calculations.
First mechanical computer or automatic computing engine concept
In 1822, Charles Babbage purposed and began developing the Difference Engine, considered to be the first automatic computing engine that was capable of computing several sets of numbers and making a hard copies of the results. Unfortunately, because of funding he was never able to complete a full-scale functional version of this machine. In June of 1991, the London Science Museum completed the Difference Engine No 2 for the bicentennial year of Babbage's birth and later completed the printing mechanism in 2000.
Later, in 1837 Charles Babbage proposed the first general mechanical computer, the Analytical Engine. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory and is the first general-purpose computer concept. Unfortunately, because of funding issues this computer was also never built while Charles Babbage's was alive. In 1910, Henry Babbage, Charles Babbage's youngest son was able to complete a portion of this machine and was able to perform basic calculations.
First programmable computer
The Z1, originally created by Germany's Konrad Zuse in his parents living room in 1936 to 1938 and is considered to be the first electro-mechanical binary programmable (modern) computer and really the first functional computer.
The first electric programmable computer
The Colossus was the first electric programmable computer and was developed by Tommy Flowers and first demonstrated in December 1943. The Colossus was created to help the British code breakers read encrypted German messages.
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). The ABC was an electrical computer that used vacuum tubes for digital computation including binary math and Boolean logic and had no CPU. 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.
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, nicknamed "Baby".
First stored program computer
First delivered to the United States Government in 1950, the UNIVAC 1101 or ERA 1101 is considered to be the first computer that was capable of storing and running a program from memory.
First commercial computer
In 1942, Konrad Zuse begin working on the Z4, which later became the first commercial computer after being sold to Eduard Stiefel a mathematician of the Swiss Federal Institute of Technology Zurich on July 12, 1950.
