Charles Babbage
interesting fact: known as "father of computing"
he designed the first automatic calculator called the analytical engine(based off the difference machine) -
Herman Hollerith
developed a mechanical tabulator based on punched cards to rapidly tabulate statistics from millions of pieces of data. He was the founder of the Tabulating Machine Company
interesting fact: known as father of modern machine data proccessing -
Z1 computer
Interesting fact: First calculator!
created by german inventor Konrad Zuse
was thought to be the first computer to include certain features integral to todays systems. -
Period: to
1st generation computers
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
Universal automic computer or UNIVAC
first commercially successful electronic digital computer interesting fact: it predicted the outcome of the stevenson-eisenhower presidental race -
Period: to
2nd generation computers
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. -
Jack Kilby
he invented the worldest first integrated circuit, a small chip capable of containing thousands of transistors. enabling computers to become smaller and lighter.
interesting fact: Started 3rd generation computers -
BASIC
changed software for the better
it was pretty much a computer language that was easier to learn, thus making the name alot more understandable(basic)
interesting fact: Even though some companys like apple and microsoft competed, in the early days, BASIC was their choice of easy to use computer language -
Period: to
3rd generation computers
The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers. -
Period: to
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 the GUI
it allowed users to interact with the computer much more easily. which apple was the company to take full commercial use of ite GUI system was first used on the alto computer but never sold because of $17,000 price
interesting fact: wasnt invented by a computer company -
Altair Computer
First personal computer,.
Not very user friendly since it had no keyboard or monitor, but it marked the start of the personal computer boom.
Interesting fact: the altair was meant to be a build-it-yourself computer but it ended up creating the huge co, microsoft. -
Bill Gates
Bill gates and paul Allen are the founders of microsoft.
they used BASIC to write their program for the altair. This program eventually led to the creation of microsoft
interesting fact: he was named the wealthiest man from the years 1995-2009 except 2008 where he was 3rd -
Steve Jobs
created Apple! his main partner and friend was Wozniak, they ended up revolutionizing the music industry, even though he started out creating one of the first computers apple I
Interesting fact: Didnt really do much developing but moreover sold the product -
Apple II
COLOR and GAME!!
however the biggest and most time saving item that Apple II brought to the playing field was simply memory saved on a ROM.
interesting fact: Apples logo got gay, literally. Instead of a boring plain logo, the logo got combined with a rainbow to show the products new use of color. -
Visicalc
VisiCalc was the first spreadsheet computer program, originally released for the Apple II. 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. -
wordstar
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 but later ported to DOS -
Osborne Computer
The birth of portable computing.
Even though it weighed a wopping 24.5 pounds and only had a 5in screen, it cost $4,612 of today's us dollars. Still the first laptop though, crappy of a deal as it might be.
interesting fact: the first osbornes had a 15% fail rate -
page maker
A full-featured desktop publishing program for Windows and Macintosh from Adobe. PageMaker was the standard in the graphics arts industry for many years for creating ads, brochures, newsletters and books of all sizes and kinds. it wsa originally for the Mac in 1985 by Aldus Corporation -
Excel
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. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications
interesting fact: excel was not the first spread sheet program, they created the multiplan in 1982 -
Mosaic
interesting fact: The worldest first web browser , this browser allowed users to view multimedia on the web, causing internet traffc to increase by nearly 350% -
Eniac
Electronic Numerical Integrator and computer(Eniac)
developed to calculate the settings used for weapons
but it is generally thought as the first successful high-speed electronic digital computer
Interesting fact: had 18,000 vacuum tubes filling up an entire room -
Netscape
U.S. computer services company, best known for Netscape Navigator, its web browser. Netscape's web browser was once dominant in terms of usage share, but lost most of that share to Internet Explorer during the first browser war. it was originally founder the title Mosaic Communications Corporation on April 4, 1994
