Before the computer was invented and developed into the highly functional machines that we know today, people used to perform a range of repetitive jobs that involved a lot of computing. These routine tasks involved drafting navigational tables, drawing charts, and even determining planetary positions for astronomical reporting. However thesummary history of computer began as early as 2000 years ago, when the abacus was first used for arithmetic purposes. The abacus contains a wooden rack that holds a couple of horizontal wires where beads are strung on them. The Astrolabe nonetheless, which was an invention of Blaise Pascal, is also being credited for having introduced the very first digital computer during the year 1962.
The very first programmable computer came into existence beginning in 1936 to 1938, and was known as the Z1. This computer was created by Konrad Zuse of Germany, and is now known today to be the first ever electrical binary programmable computer. However to get to know the complete summary history of computer, it is best to look back into the time when the first digital computer was finally developed. In 1937 the ABC or Atanasoff-Berry Computer was developed first by John Vincent Atanasoff, a professor, and Cliff Berry, a graduate student. Although the ABC computer is considered to be the first digital computer, the ENIAC computer by J. Presper Eckert and John Mauchly is known to be the first functional digital computer.
The first generation computers were developed beginning the 1940s and its architecture was based on huge electronic value. The very first computers were massive, slow, and had very limited computing capabilities. The ENIAC 1 for example necessitated 20,000 vacuum tubes for its operation. Due to their physical inconveniences and slow capabilities, the need for smaller but faster computers became more apparent.
Eventually, programming languages were created, and computers were used extensively in banks, beginning in 1959. In 1958 the integrated circuit or chip became one of the most basic requirements for computer systems. After several years, manufacturers such as IBM, Scelbi, and Apple began to develop systems that started the trend of home or personal computers. Today, computers have become an integral component of modern life, and are being used almost everywhere: in households and schools as well as in huge enterprises and industries, such as supercomputers. By looking into the summary history of computer, you will be better able to trace its roots and understand more clearly how these super machines of today first evolved.
