frist printer is invented
Xerography (or electrophotography) is a photocopying technique developed by Chester Carlson in 1938 and patented on October 6, 1942. He received U.S. Patent 2,297,691 for his invention. -
First general computer created
In February 15, 1946, the first general computer was created. It took up 1800 square feet and it weighed around 57,000 pounds. It was able to perform around 5,000 additions per second, or 357 multiplications per second, which was around 1000 times faster than other machines of the day. Also, it featured 17,468 vacuum tubes, 70,000 resistors, 7,200 diodes, 10,000 capacitors, and there were around 5 million joints that needed to be hand-soldered. In order to power this, it took 150 kW of electrici -
First transistor
The first transistor was developed in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. -
first disk drive is invented
The IBM 350 disk storage unit, the first disk drive, was announced by IBM as a component of the IBM 305 RAMAC computer system on September 13, 1956. This drive had a total capacity of five million 6-bit characters (3.75megabytes). -
FORTAN programming language invented
The language Fortran(developed at IBM in the mid 1950s) and LISP (1958) became the first widely used high-level general purpose programming language. The earliest version of FORTRAN was released in 1957 as a programming tool for the IBM 704. LISP had a partial implementation (apply-based) running in late 1958, and a full implementation (eval-based) possibly in Dec 1958, no later than Mar 1959. -

Frst TI hand-held calculator was invented
The first TI hand-held calculator was invented in 1967. -
Arpanet was invented
The Advanced Research Projects Agency Network (ARPANET) was an early packet switching network and the first network to implement the protocol suite TCP/IP, invented in 1969. It became the technical foundation of the Internet. Packet switching—today the dominant basis for data communications worldwide—was a new concept at the time of the conception of the ARPANET. Prior to the advent of packet switching, both voice and data communications had been based on the idea of circuit switching, as in the -
First email sent
Sometime in late 1971, a computer engineer named Ray Tomlinson sent the first e-mail message. "I sent a number of test messages to myself from one machine to the other," he recalls. -
