1st generation computers (Vacuum Tubes)
The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. -
UNIVAC
Founder: John Mauchly a line of electronic digital stored-program computers starting with the products of the Eckert-Mauchly Computer Corporation. it is an acronym for UNIVersal Automatic Computer
When the predictions proved true and Eisenhower won a landslide within 1% of the initial prediction, Charles Collingwood, the on-air announcer, embarrassingly announced that they had covered up the earlier prediction. -
ENIAC (Electronic Numerical Integrator And Computer) $500,000
"The Giant Brain!"
ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.ENIAC's design and construction was financed by the United States Army, Ordnance Corps, Research and Development Command which was led by Major General Gladeon Marcus Barnes. the City of Philadelphia declared February 15 as The ENIAC Day. -

2nd generation computers (Transistors)
Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. -
Period: to
Third Generation (1964-1971) Integrated Circuits
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. -
BASIC (Beginner's All-purpose Symbolic Instruction Code)
Designed by John George Kemeny and Thomas Eugene Kurtz. The BASIC language was mainly thought of because they wanted to enable students in fields other than science and mathematics to use computers. BASIC remains popular in many dialects and in new languages influenced by BASIC, such as Microsoft's Visual Basic. -
Period: to
Fourth Generation (1971-Present) Microprocessors
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, located all the components of the computer, from the central processing unit and memory to input/output controls, on a single chip. -
Intro to the GUI (Graphical user interface)
invented by researchers at the Stanford Research Institute. The PARC user interface consisted of graphical elements such as windows, menus, radio buttons, and check boxes. The concept of icons was later introduced by David Smith, who had written a thesis on the subject under the guidance of Kay. -
Altair computer 8800 $661
Ed Roberts and Bill Yates finished the first prototype creating the best microcomputer around using a knowledge based on the Intel 8080 CPU software. this software started the beginning of electronic calculators and video games like a game we know today as Pong. The US Air Force later decided to use their electronics background to produce small kits for model rocket hobbyists. -
Apple Computer 2 (now Apple inc.) $1,298
First thought of by creators Steve Wozniak and Steve Jobs. This computer was built with the MOS Technology 6502 microprocessor running at 1 MHz, and including two game paddles on an 8-bit home computer, one of the first highly successful mass-produced microcomputer products. "To me, a personal computer should be small, reliable, convenient to use and inexpensive". -Wozniak -
WordStar
Developed by Rob Barnaby, wordStar is a word processor application that had a dominant market share during the early- to mid-1980s. Formerly published by MicroPro International, it was originally written for the CP/M operating system. WordStar was the first microcomputer word processor to offer mail merge and WYSIWYG. -
Osborne 1 (Osborne Computer Corp) $1,795
First brought to the commerical public by Adam Osborne and Lee Felsenstein. thus using the CP/M 2.2 operating system. The Osborne one personal computer is the first personal computer to have been deployed in a military field operation. although this microcomputer was great for this field, it lacked in not supporting a bit-mapped graphic pack for any video games wanted to be played. -
VisiCalc
was the first spreadsheet computer program, originally released for the Apple II. VisiCalc traces its history to a presentation that Dan Bricklin was watching while attending Harvard Business School. The professor was creating a financial model on a blackboard that was ruled with lines to create a table, and formulas and data were being written into the cells. -
Adobe pagemaker (Aldus Corporation)
PageMaker was one of the first desktop publishing programs. Initially for the then-new Apple Macintosh and in 1987 for PCs running Windows 1.0.[3] As an application relying on a graphical user interface, PageMaker helped to popularize the Macintosh platform and the Windows environment. -
NCSA Mosaic (Mosaic) Web browser
The very first web browser. in general, non-commercial use was free of charge for all versions (with certain limitations). Additionally, the X Window System/Unix version publicly provided source code. Twenty years after Mosaic's introduction, the most popular contemporary browsers, Google Chrome, Internet Explorer, Safari, and Mozilla Firefox retain many of the characteristics of the original Mosaic graphical user interface (GUI) -
Netscape Communications (Netscape)
Netscape is credited with developing the Secure Sockets Layer Protocol (SSL) for securing online communication, which is still widely used, as well as JavaScript, the most widely used language for client-side scripting of web pages. -Netscape stock traded from 1995 until 1999 when it was acquired by AOL in a pooling-of-interests transaction ultimately worth US$10 billion -
Excel (microsoft)
Excel is an electronic spreadsheet program that can be used for storing, organizing and manipulating data. From its first version Excel supported end user programming of macros (automation of repetitive tasks) and user defined functions (extension of Excel's built-in function library). In early versions of Excel these programs were written in a macro language whose statements had formula syntax and resided in the cells of special purpose macro sheets.
