Sytek
Sytek, Inc., known as Hughes LAN Systems, Inc. (HLS), after being acquired by Hughes Electronics and known as Whittaker Communications, Inc. (WCI), since April 24, 1995, created the NetBIOS API, used by Microsoft to make its early networks. Sytek was founded in Silicon Valley and last officed in their own building on Charleston Road in Mountain View, California, Mountain View. During this crucial period in Local area network, LAN development, there were two factions within IBM competing over the basic LAN architecture. One group, the telco switch folks from Geneva liked a central hub, with a network of distributed twisted pair conductors, as is used in phone systems. The other group, Entry Systems Division from Boca Raton, liked the idea of a distributed bus architecture. Building on prior work done by such companies as Intech Labs (aka American Modem & AMDAX), Sytek built an radio frequency, RF transceiver that operated on cable TV frequencies. It received in the High VHF band ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NetBIOS
NetBIOS () is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol. Operating systems of the 1980s (DOS and Novell Netware primarily) ran NetBIOS over IEEE 802.2 and IPX/SPX using the NetBIOS Frames (NBF) and NetBIOS over IPX/SPX (NBX) protocols, respectively. In modern networks, NetBIOS normally runs over TCP/IP via the NetBIOS over TCP/IP (NBT) protocol. NetBIOS is also used for identifying system names in TCP/IP (Windows). History and terminology NetBIOS is an operating system-level API that allows applications on computers to communicate with one another over a local area network (LAN). The API was created in 1983 by Sytek Inc. for software communication over IBM PC Network LAN technology. On IBM PC Network, as an API alone, NetBIOS relied on proprietary Sytek ...

IBM PC Network
The IBM PC Network was IBM PC's first LAN system. It consisted of network cards, cables, and a small device driver known as NetBIOS (Network Basic Input/Output System). It used a data rate of and carrier-sense multiple access with collision detection. NetBIOS was developed by Sytek Inc as an API for software communication over this IBM PC Network LAN technology; with Sytek networking protocols being used for communication over the wire. IBM's later Token Ring network emulated the NetBIOS application programming interface, and it lived on in many later systems. Broadband The original broadband version in 1984 communicated over 75 Ω cable television compatible co-axial cable with each card connecting via a single F connector. Separate transmit and receive frequencies were used. Cards could be ordered that used different frequencies so multiple cards could transmit simultaneously, at each. A Sytek head-end device was required to translate from each card's transmit frequency t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ungermann-Bass
Ungermann-Bass, Inc., also known as UB and UB Networks, was a computer networking company in the 1980s to 1990s. Located in Santa Clara, California, UB was the first large networking company independent of any computer manufacturer. Along with competitors 3Com and Sytek, UB was responsible for starting the networking business in Silicon Valley in 1979. UB was founded by Ralph Ungermann and Charlie Bass. John Davidson, vice president of engineering, was one of the creators of NCP, the transport protocol of the ARPANET before TCP. UB specialized in large enterprise networks connecting computer systems and devices from multiple vendors, which was unusual in the 1980s. At that time most network equipment came from computer manufacturers and usually used only protocols compatible with that one manufacturer's computer systems, such as IBM's SNA or DEC's DECnet. Many UB products initially used the XNS protocol suite, including the flagship Net/One, and later transitioned to TCP/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3Com
3Com Corporation was an American digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Bill Krause joined as President in 1981. Metcalfe explained the name 3Com was a contraction of "Computer Communication Compatibility", with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers. 3Com provided network interface controller and switches, routers, wireless access points and controllers, IP voice systems, and intrusion prevention systems. The company was based in Santa Clara, California. From its 2007 acquisition of 100 percent ownership of H3C Technologies Co., Limited (H3C) —initially a joint venture with China-based Huawei Technologies—3Com achieved a market presence in China, and a significant networking market share in Europe, Asia, and the Americas. 3Com products were sold under the brands 3Com, H3C, and TippingPoi ...

Token Ring
Token Ring is a Physical layer, physical and data link layer computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE Standards Association, IEEE 802.5. It uses a special three-byte frame (networking), frame called a ''token'' that is passed around a logical ''ring'' of workstations or server (computing), servers. This token passing is a channel access method providing fair access for all stations, and eliminating the collision (telecommunications), collisions of contention (telecommunications), contention-based access methods. Following its introduction, Token Ring technology became widely adopted, particularly in corporate environments, but was gradually eclipsed by newer iterations of Ethernet. The last formalized Token Ring standard that was completed was Gigabit Token Ring (IEEE 802.5z), published on May 4, 2001. History A wide range of different local area network technologies were developed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Companies Disestablished In 1996
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of comput ...
