  • PDP-8

    PDP-8
    linkThe 12-bit PDP-8 was the first successful commercial minicomputer, produced by Digital Equipment Corporation (DEC) in the 1960s. DEC introduced it on 22 March 1965, and sold more than 50,000 systems, the most of any computer up to that date.

  • Merit Network

    Merit Network
    linkMerit Network, Inc., is a nonprofit member-governed organization providing high-performance computer networking and related services to educational, government, health care, and nonprofit organizations, primarily in Michigan.[1] Created in 1966, Merit operates the longest running regional computer network in the United States.

  • ARPHANET

    ARPHANET
    linkARPANET protected the flow of information between military installations by creating a network of geographically separated computers that could exchange information via a newly developed protocol (rule for how computers interact) called NCP (Network Control Protocol).

  • ALOHAnet

    ALOHAnet
    linkALOHNET was the very first wireless local area network (WLAN). This first WLAN consisted of 7 computers that communicated in a bi-directional star topology.

  • Ethernet

    Ethernet
    linkBob Metcalfe, David Boggs, and Tat Lam built the first Ethernet prototype at 2.94 Mbps. Bob Metcalfe at Xerox PARC documented the invention of Ethernet in a memo, which described communication across different "ethers" - including cable, telephone, and radio - building on the ALOHAnet protocol

  • Cray supercomputer

    Cray supercomputer
    linkThe company's first product, the Cray-1 supercomputer was a major success when it was released. It was faster than all other computers at the time. The first system was sold within a month for US$8.8 million.

  • IBM PC

    IBM PC
    linkThe 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.

  • 4g

    4g
    link(LTE) have been on the market since 2006[ and 2009 respectively, and are often branded as 4G in marketing materials. The current versions of these technologies provide downstream peak bitrates of 144 Mbit/s and 100 Mbit/s respectively, and do consequently not fulfill the original ITU-R requirements of data rates approximately up to 1 Gbit/s for 4G systems.

  • Macbook

    Macbook
    linkThe MacBook was a brand of Macintosh notebook computers manufactured by Apple Inc. from 2006 to 2011. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple–Intel transition. Positioned as the low end of the MacBook family, the Apple MacBook was aimed at the consumer and education markets.

  • Macbook Air

    Macbook Air
    linkOn July 20, 2011, Apple released an updated model in the same form factor as the prior model. The new model was powered by the new Sandy Bridge 1.6 or 1.7 GHz dual-core Intel Core i5, or 1.8 GHz dual-core Intel Core i7 processors, that came with an Intel HD Graphics 3000 processor, and with a backlit keyboard, two USB 2.0 ports, a 720p FaceTime camera, a standard of 2 gigabytes of RAM though configurable up to 4GB,
