A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, for sharing data and devices between each other, including Internet access. Ethernet and Wi-Fi are the two most common technologies used for local area networks; historical network technologies include ARCNET, Token Ring and LocalTalk.
A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet.
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.
A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
Systems Network Architecture (SNA) is IBM's proprietary networking architecture, created in 1974. It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software. The implementation of SNA takes the form of various communications packages, most notably Virtual Telecommunications Access Method (VTAM), the mainframe software package for SNA communications.
A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer. In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network. Basically, a VLAN behaves like a virtual switch or network link that can share the same physical structure with other VLANs while staying logically separate from them. VLANs work by applying tags to network frames and handling these tags in networking systems, in effect creating the appearance and functionality of network traffic that, while on a single physical network, behaves as if it were split between separate networks. In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed.
Fibre Channel (FC) is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data. Fibre Channel is primarily used to connect computer data storage to servers in storage area networks (SAN) in commercial data centers.
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.
Banyan VINES is a discontinued network operating system developed by Banyan Systems for computers running AT&T's UNIX System V.
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. Units which are the last receiver or generate data are called hosts, end systems or data terminal equipment.
Judith "Judy" L. Estrin is an American entrepreneur, business executive, and philanthropist. She co-founded eight technology companies. Estrin worked with Vinton Cerf on the Transmission Control Protocol project at Stanford University in the 1970s. She was the chief technology officer of Cisco Systems from 1998 to 2000. Since 2007, Estrin has been the CEO of JLABS, LLC, a privately held company focused on furthering innovation in business, government, and nonprofit organizations.
A computer network is a set of computers sharing resources located on or provided by network nodes. Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.
Network Systems Corporation (NSC) was an early manufacturer of high-performance computer networking products. Founded in 1974, NSC produced hardware products that connected IBM and Control Data Corporation (CDC) mainframe computers to peripherals at remote locations. NSC also developed and commercialized the HYPERchannel networking system and protocol standards, adopted by Cray Research, Tektronix and others. In the late 1980s, NSC extended HYPERchannel to support the TCP/IP networking protocol and released a product allowing HYPERchannel devices to connect to the emerging Internet.
Dust Networks, Inc. is an American company that specializes in the design and manufacture of wireless sensor networks for industrial applications including process monitoring, condition monitoring, asset management, environment, health and safety (EHS) monitoring, and power management. They were acquired by Linear Technology, Inc in December 2011, which in turn was acquired by Analog Devices, Inc. in 2017. The Dust Networks product team operates in the IoT Networking Platforms group of Analog Devices.
Data center bridging (DCB) is a set of enhancements to the Ethernet local area network communication protocol for use in data center environments, in particular for use with clustering and storage area networks.
William "Bill" N. Carrico Jr. is an American computer scientist and businessman who founded several technology companies in Silicon Valley. He was the president and CEO of 3Com, senior vice president of Cisco Systems, and chairman of Packet Design.
Hewlett Packard Enterprise Networking is the Networking Products division of Hewlett Packard Enterprise ("HP"). HPE Networking and its predecessor entities have developed and sold networking products since 1979. Currently, it offers networking and switching products for small and medium sized businesses through its wholly owned subsidiary Aruba Networks. Prior to 2015, the entity within HP which offered networking products was called HP Networking.
Integrated Device Technology, Inc. (IDT), was an American semiconductor company headquartered in San Jose, California. The company designed, manufactured, and marketed low-power, high-performance mixed-signal semiconductor products for the advanced communications, computing, and consumer industries. The company marketed its products primarily to original equipment manufacturers (OEMs). Founded in 1980, the company began as a provider of complementary metal-oxide semiconductors (CMOS) for the communications business segment and computing business segments. The company focused on three major areas: communications infrastructure, high-performance computing, and advanced power management. Between 2018 and 2019, IDT was acquired by Renesas Electronics.
SAT>IP specifies an IP-based client–server communication protocol for a TV gateway in which SAT>IP servers, connected to one or more DVB broadcast sources, send the program selected and requested by an SAT>IP client over an IP-based local area network in either unicast for the one requesting client or multicast in one datastream for several SAT>IP clients.
Packet Design was an Austin, Texas-based network performance management software company credited with pioneering route analytics technology. This network monitoring technology analyzes routing protocols and structures in meshed IP networks by participating as a peer in the network to passively “listen” to Layer 3 routing protocol exchanges between routers for the purpose of network discovery, mapping, real-time monitoring and routing diagnostics.
