Tablet computers
The tablet computer and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1915 http://en.wikipedia.org/wiki/History_of_tablet_computers -
differential analyzer
The differential analyzer ( invented by Vannevar Bush) is introduced as the first serious attempt to design a computer that can do many kinds of scientific computations. It is the herald of the modern computer age. http://ftp.vvm.com/~jhunt/compupedia/History_of_Computers/history_of_computers_1930.htm -

The Programma 101
The Programma 101 was the first commercial "desktop personal computer", produced by the Italian company Olivetti and invented by the Italian engineer Pier Giorgio Perotto, inventor of the magnetic card system. The project started in 1962. It was launched at the 1964 New York World's Fair, and volume production began in 1965, the computer retailing for $3,200. http://en.wikipedia.org/wiki/Personal_computer -
Intergalactic Computer Network
the first director of the Information Processing Techniques Office (IPTO) at the The Pentagon's ARPA, used the term in the early 1960s to refer to a networking system he “imagined as an electronic commons open to all, ‘the main and essential medium of informational interaction for governments, institutions, corporations, and individuals http://en.wikipedia.org/wiki/Intergalactic_Computer_Network -

ALOHNET
During World War II, the United States Army first used radio signals for data transmission. This inspired a group of researchers in 1971 at the University of Hawaii to create the first packet based radio communications network called ALOHNET. ALOHNET was the very first wireless local area network (WLAN). This first WLAN consisted of 7 computers that communicated in a bi-directional star topology. http://www.arp.sprnet.org/default/inserv/trends/history_wireless.htm -

the Alto
Researchers at the Xerox Palo Alto Research Center designed the Alto -- the first work station with a built-in mouse for input. The Alto stored several files simultaneously in windows, offered menus and icons, and could link to a local area network. XEngineers later incorporated its features into work stations and personal computers.

first generation of WLAN
The first generation of WLAN technology used an unlicensed band (902-928 MHz ISM), which later became crowded with interference from small appliances and industrial machinery. A spread spectrum was used to minimize this interference, which operated at 500 kilobits per second. http://www.arp.sprnet.org/default/inserv/trends/history_wireless.htm -
Windows OS
Microsoft focuses on a new operating system—the software that manages, or runs, the computer hardware and also serves to bridge the gap between the computer hardware and programs, such as a word processor. It’s the foundation on which computer programs can run. They name their new operating system "MS‑DOS." http://windows.microsoft.com/en-us/windows/history#T1=era0 -
IBM PC
The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It is IBM model number 5150, and was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida. http://en.wikipedia.org/wiki/IBM_Personal_Computer -
