The world of computers has dominated the human race for more than 50 plus years. However, the history about imagining the concept of computers and the in between efforts to bring the computer concept to reality is no less colorful. The first computer company named as the Electronic Controls Company was formed in 1949 by J. Presper Eckert and John Mauchly. The genealogy of computers has very many contributors and only a few of the milestones are noted here. The contributions miniscule or small have only helped the journey of computers a step forward. The history notes that between 1939-45 several efforts were made to make computers a reality.
Model K (1937 -1939)
In 1939 when the Bello Laboratories scientist George Stibitz introduced a demonstration circuit called K. The initial “K” was meant to be a reminder that the circuit was designed on a kitchen platform, it was the first time in history where a proof of concept where Boolean logic was used in the making of computers was introduced. However, there is something about Palo Alto & garages that have a strong affiliation with technology traditions. It is 1940 Hewlett Packard was started in Palo Alto and their first product an audio oscillator 200A was used by Disney in some 12 movie theaters. It is interesting to note that the journey towards modern computers has many middle stops where researchers imagined it to be the next intellectual version of a calculator.
Z3: The First Programmable Computer (1936-1938)
The computer creation bug had bitten the western world equally and while Model K was considered a starting point in computers history in America, the German scientist Konrad Zuse is credited as the first individual in history to have made the first binary programmable computer. The computer was called Z3 taking over his own initial concept of Z3 was reconstructed in 1960 and the proud efforts still can be seen and read about in Munich museum. The Z3 was the first programmable computer. The Z3 had 22-bit word length.
The 701 (1953 & The First Personal Computer (1981)
The first personal computer was introduced on April7, 1953 by IBM. It was the first computer that was produced on a mass scale and was electric in its configuration. The IBM;s sales for 701 reached a number of 19701 computers. The early main clients of IBM were the aircraft companies, the government and research establishments. The computer 701 could be rented for $15000 and this invention also set IBM on path of launching large-scale computer market. In 1981, the first personal computer (PC) was launched by IBM called the IBM PC. The code name for this computer was ACORN and used MS DOS as the operating system.
The First Laptop Computer
The first notable efforts for a portable computer were made by IBM and in 1975 IBM 5100 is recorded as the first Laptop or portable computer machine available. However, the first laptop invention credit is often awarded to Adam Osborne. In 1981 he developed “Osborne I which costed $179.
The world of computers after this had many new developments which mainly targeted the operating systems and software’s which could make the computing experience easier and enjoyable. One such ahead of the market step was taken by Steve Wozniak when he came up with the first Apple machine concept which has the unimaginable in those day’s multimedia concepts integrated into it.
