The Z3 Computer
The Z3 is an early computer made by German engineer Konrad Zuse that uses 2,300 relays, performs binary arithmetic and has a 22-bit word length. The Z3 was used for aerodynamic calculations but got destroyed in a bombing raid.Timeline -
The Harvard Mark 1
Thought of by Harvard physics professor Howard Aiken, and designed and built by IBM, the Harvard Mark 1 is a room-sized, relay-based calculator.The machine had a fifty-foot long camshaft running the length of machine that synchronized the machine’s thousands of component parts and used 3,500 relays.Timeline -
The ENIAC CPU
The ENIAC was the first electronic general-purpose computer.it was a Turning-complete,digital and could solve "a large class of numeric problems" through reprogramming.Although ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory,its first programs included a study of the feasibility of the thermonuclear weapon.Wikipedia -
The CSIRAC
The CSIRAC was Australia's first computer.As part of preparations for a demonstration of CSIRAC during the first Australian Conference on Automatic Computing Machines, he programmed it to play several songs.Timeline -
The ERA 1101
The ERA 1101 was one of the first commercially produced computers, the company´s first customer was the US Navy.The 1101, designed by ERA but built by Remington-Rand, was intended for high-speed computing and stored 1 million bits on its magnetic drum.Timeline -
First video game
William Higinbotham created what is thought to be the first video game. It was a very simple tennis game, similar to the classic 1970s video game Pong, and it was pretty popular at a Brookhaven National Laboratory open house. Higinbotham made some drawings, and blueprints were drawn up. Technician Robert Dvorak spent about two weeks building the device.They called the game Tennis for Two. APS physics -
The first mouse
Independently, Douglas Engelbart at the Stanford Research Institute invented his first mouse prototype in the 1960s with the assistance of his lead engineer Bill English.They made the device the mouse as early models had a cord attached to the rear part of the device looking like a tail and generally resembling the common mouse.Wikipedia -
ARPANET first network
ARPANET was the first network created by the U.S. government by a group called DARPA. First packet switching network that developed into today's modern internet.Wikipedia -
The first overhead projector
Also called a "viewgraph," the overhead projector was created by Jules Duboscq, a French inventor, in the 1870s. It was first used for police work, and used a cellophane roll over a 9-inch stage allowing facial characteristics to be rolled across the stage. Buhl Industries was founded in 1953, and became the leading US contributor for several optical refinements for the overhead projector and its projection lens.Wikipedia -
The first mobile phone
Mobile phones were invented as early as the 1940s when engineers working at AT&T developed cells for mobile phone base stations.Motorola, on 3 April 1973 were first company to mass produce the the first handheld mobile phone. -
The Ethernet
The Ethernet is a family of computer networking technologies usually used in LANs or local area networks and MANs or metropolitan area networks.Over time, the Ethernet has largely replaced competing wired LAN technologies.Wikipedia -
The first laptop
The Osborne 1, released in 1981, used the Zilog Z80 and weighed 23.6 pounds. It had no battery, a 5in CRT screen, and dual 5.25in single-density floppy drives. -
Bluetooth wireless connection between devices
Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices and building Personal Area Networks(PANs). Invented by telecom vendor Ericsson in 1994. It can connect several devices, overcoming problems of synchronization. Wikipedia -
First computer keyboard
As early as the 1870s, teleprinter-like devices were used to simultaneously type and transmit stock market text data from the keyboard across telegraph lines to stock ticker machines to be immediately copied and displayed onto ticker tape.
