computer history timeline
The history of computers dates back to 19th century. The first mechanical computer, invented by Charles Babbage, is considered precursor to modern computers. But, it wasn't until 20th century that computers became more accessible and evolved into machines we know today.
Here is a timeline of major milestones in computer history:
1937 - Alan Turing invents concept of a universal computing machine, which eventually led to development of modern computers.
1941 - Konrad Zuse builds first programmable computer, named Z3.
1946 - ENIAC, first electronic computer, was unveiled by John Mauchly and J. Presper Eckert at University of Pennsylvania. Weighing 30 tons, ENIAC was used for military calculations during World War II.
1951 - Remington Rand introduces first commercial computer, UNIVAC I, which was used by US Census Bureau.
1958 - Jack Kilby of Texas Instruments invents first integrated circuit, which allows many transistors to be packed into a small chip. This innovation revolutionized electronics industry.
1964 - IBM unveils System/360, a family of computers aimed at businesses and government agencies. This system was first to use operating systems that could run different software on different machines.
1969 - The ARPANET, a precursor to internet, is created by US Department of Defense as a way for researchers to share information. The first message sent over network was "LO" (short for "login").
1971 - Intel introduces first microprocessor, Intel 4004, which was used in calculators and other small devices.
1976 - Steve Jobs and Steve Wozniak found Apple Computer, and Apple I was their first product.
1981 - IBM releases PC, which becomes standard for personal computers.
1985 - Microsoft releases Windows, a graphical user interface that made it easier for people to use computers.
1991 - Tim Berners-Lee invents World Wide Web, a system of interlinked documents that could be accessed via internet.
1998 - The first Google search engine is released by Larry Page and Sergey Brin.
2007 - Apple releases iPhone, which revolutionized smartphones and mobile computing.
2020 - The COVID-19 pandemic leads to a surge in remote work and online learning, highlighting importance of computers and internet in our daily lives.
In conclusion, history of computers spans over a century and has seen countless innovations and advancements. From large, room-size machines to pocket-sized smartphones, computers have transformed our daily lives and paved way for even more breakthroughs in future.
