Period: to
The First Generation
Use of vacuum tubes, big & clumsy, high electricity consumption, programming in Mechanical Language, larger AC were needed, a lot of electricity failure occured -
First point-contact transistor was tested
set off the semiconductor revolution -
Vacuum tubes were invented
-

functioned as a complete system using the Williams tube for memory -
Grace Hopper completes the A-0 Compiler
completed what is considered to be the first compiler, a program that allows a computer user to use English-like words instead of numbers -
Magnetic Core Memory installed on the Whirlwind Computer
Jay Forrester installed the Magnetic Core Memory. Core memory made computers more reliable, faster, and easier to make. -
Period: to
The Second Generation
In the second generation, transistors were used, Core Memory was developed, faster than First Generation computers, First Operating System was developed, programming was in Machine Language & Aseembly Language, magnetic tapes & discs were used, computers became smaller in size than the First Generation computers, computers consumed less heat & consumed less electricity. -
First integrated circuit was created
Jack Kilby created the first integrated circuit. His circuit consisted of a sliver of germanium with five components linked by wires. -
AT&T designed it dataphone
It was used specifically for converting digital computer data to analog signals for transmission across its long distance network. -
IBM 1301 Disk Storage Unit is released
The IBM 1301 Disk Drive was announced for use with IBM’s 7000-series of mainframe computers. Maximum capacity was 28 million characters and the disks rotated at 1,800 R.P.M. -
The LINC (Laboratory Instrumentation Computer) was introduced
It offered the first real time laboratory data processing. -
Virtual memory emerged
Virtual memory permitted a computer to use its storage capacity to switch rapidly among multiple programs or users and is a key requirement for timesharing. -
Period: to
The Third Generation
In the third-generation, integrated circuits developed, power consumption was low, SSI & MSI Technology was used, and high level languages were used. -
CDC´s 6600 supercomputer introduced
It performed up to 3 million instructions per second — a processing speed three times faster than that of its closest competitor, the IBM Stretch. -
Digital Equipment Corp. introduced the PDP-8
It was the first commercially successful minicomputer. -
Seymour Papert designs LOGO as a computer language for children
LOGO controlled the actions of a mechanical "turtle," which traced its path with pen on paper. -
Evans & Sutherland is formed
David Evans and Ivan Sutherland, both professors of computer science, founded a company to develop a special graphics computer known as a frame buffer. -
Computer-to-computer communication expanded when the Department of Defense established four nodes on the ARPANET
ARPANET´s designers set out with several goals...direct use of distributed hardware services, direct retrieval from remote, one-of-a-kind databases; and the sharing of software subroutines and packages not available on the users´ primary computer due to incompatibility of hardware or languages. -
Period: to
The Fourth Generation
The fourth-generation consisted of LSI & VLSI Technology used, development of portable computers, RAID Technology of data storage,it's used in virtual reality, multimedia, and simulation,computers started in use for Data Communication, different types of memories with very high accessing speed & storage capacity. -
The first email is sent
Ray Tomlinson of the research firm Bolt, Beranek and Newman sent the first e-mail when he was supposed to be working on a different project. -
SuperPaint is completed
SuperPaint was the first digital computer drawing system to use a frame buffer—a special high-speed memory—and the ancestor of all modern paint programs. -
Intel´s 8008 microprocessor made its debut
For the first time, a microprocessor could handle both uppercase and lowercase letters, all 10 numerals, punctuation marks, and a host of other symbols. -
Video Toaster is introduced by NewTek
The Video Toaster was a video editing and production system for the Amiga line of computers and included custom hardware and special software. -
Yahoo is founded
Yahoo started out as "Jerry's Guide to the World Wide Web" before being renamed. Yahoo originally resided on two machines, Akebono and Konishiki, both named after famous Sumo wrestlers. -
iPhone 5 is introduced
The new iPhone 5 is introduced to the world with more capabilites then the last iPhones. -
