Charles Babbage
Designed the first automatic calculator. -
Visicalc
Visicalc was the first spreadsheet application. It is often considered the application that turned the microcomputer from a hobby for computer enthusiasts into a serious business tool, and is considered the Apple II's killer app. VisiCalc sold over 700,000 copies in six years, and as many as 1 million copies over its history. -
Herman Hollerith
Herman Hollerith was the first to apply to computer and developeda mechanical tabulator based on punched cards to rapidly tabulate statistics from millions of pieces of data.Hollerith is widely regarded as the father of modern machine data processing. -
Excel
Excel is a spreadsheet application developed by Microsoft for Microsoft Windows and Mac OS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has replaced Lotus 1-2-3 as the industry standard for spreadsheets. -
Z1 Computer
Z1 was the first computer to include control unit and seperate mem. functions. It was a binary electrically driven mechanical calculator with limited programmability, reading instructions from punched tape. -
1st Generation Computers
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts. -
Eniac
ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States. ENIAC was the most powerful calculating device built to date. It was the first programmable general-purpose electronic digital computer. -
Univac
Univac was the first commercially successful electronic digital computer.UNIVAC I used 5,200 vacuum tubes, weighed 29,000 pounds (13 metric tons), consumed 125 kW, and could perform about 1,905 operations per second running on a 2.25 MHz clock. -
2nd Generation Computers
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. Second-generation computers still relied on punched cards for input and printouts for output. -
Jack Kilby
Jack invented the world's first integrated circuit. He is also the inventor of the handheld calculator and the thermal printer, for which he has patents -
BASIC
Knowledge of the relatively simple BASIC became widespread for a computer language. The original BASIC language was designed on May 1, 1964 by John Kemeny and Thomas Kurtz and implemented by a team of Dartmouth students under their direction. BASIC (an acronym for Beginner's All-purpose Symbolic Instruction Code) -
3rd Generation Computers
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors. -
4th Generation Computers
The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip. -
Introduction of GUI
GUI, graphical user interface, was not invented by a computer company but it allowed users to interact with computers easily. As well as computers, GUIs can be found in hand-held devices such as MP3 players, portable media players, gaming devices and smaller household, office and industry equipment. -
Altair Computer
Altair computer were the first personal computers. No keyboard, no monitor and not user friendly. It was controlled y front panel switches and was introduced in January and available in February 1975 to be sold. -
Steve Jobs
Steve Jobs was an American entrepreneur, marketer, and inventor,who was the co-founder, chairman, and CEO of Apple Inc. In 2003, Jobs was diagnosed with a pancreas neuroendocrine tumor. -
Apple II
New features including a color display, eight internal expansion slots, sound and game. The Apple II was one of the first computer with a color display, and it has the BASIC programming language built-in, so it is ready-to-run right out of the box. The Apple II was probably the first user-friendly system. -
Wordstar
Was the frstword processing application. WordStar was deliberately written to make as few assumptions about the underlying system as possible, allowing it to be easily ported across the many platforms that proliferated in the early 1980s.This was developed by Rob Barnaby. -
Osborne Computer
Osborne was the first portable but heavy computer. The Osborne 1 was developed by Adam Osborne and was the size of a sewing machine and was advertised as the only computer that would fit underneath an airline seat. After a few years osborne was closed down due to bankruptcy. -
Bill Gates
Bill Gates was the founder of Microsoft, the world’s largest personal-computer software company. -
Pagemaker
Pagemaker was the first desktop publishing software. PageMaker relies on Adobe Systems PostScript page description language. -
Mosaic
Mosaic was the name of the first browser. Mosaic was developed at the National Center for Supercomputing Applications (NCSA) -
Netscape
Netscape Browser is the name of a proprietary Windows web browser published by AOL, but developed by Mercurial Communications. It is the eighth major release in name of the Netscape series of browsers, originally produced by the defunct Netscape Communications Corporation.
