SynOptics Communications
SynOptics Communications was a Santa Clara, California-based early computer network equipment vendor from 1985 until 1994. SynOptics popularized the concept of the modular Ethernet hub and high-speed Ethernet networking over copper twisted-pair and fiber optic cables. History SynOptics Communications was founded in 1985 by Andrew K. Ludwick and Ronald V. Schmidt, both of whom worked at Xerox's Palo Alto Research Center (PARC). The most significant product that Synoptics produced was LattisNet (originally named AstraNet) in 1987. This meant that unshielded twisted-pair cabling already installed in office buildings could be re-utilized for computer networking instead of special coaxial cables. The star network topology made the network much easier to manage and maintain. Together these two innovations directly led to the ubiquity of Ethernet networks. Before the final standard version of what is known today as the 10BASE-T protocol, there were several different methods and standa ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

10BASE-2
10BASE2 (also known as cheapernet, thin Ethernet, thinnet, and thinwire) is a variant of Ethernet that uses thin coaxial cable terminated with BNC connectors to build a local area network. During the mid to late 1980s this was the dominant 10 Mbit/s Ethernet standard, but due to the immense demand for high-speed networking, the low cost of Category 5 cable, and the popularity of 802.11 wireless networks, both 10BASE2 and 10BASE5 have become increasingly obsolete, though devices still exist in some locations. As of 2011, IEEE 802.3 has deprecated this standard for new installations. Name origination The name ''10BASE2'' is derived from several characteristics of the physical medium. The ''10'' comes from the transmission speed of 10 Mbit/s. The ''BASE'' stands for baseband signaling, and the ''2'' for a maximum segment length approaching 200 m (the actual maximum length is 185 m). Signal encoding 10 Mbit/s Ethernet uses Manchester coding. A binary zer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Companies Established In 1985
A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is generating profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations. Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups. Meanings and definitions A company can be defined as an "artificial per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SynOptics Network Management Protocol
The Nortel Discovery Protocol (NDP) is a data link layer (OSI Layer 2) network protocol for discovery of Nortel networking devices and certain products from Avaya and Ciena. The device and topology information may be graphically displayed network management software. The Nortel Discovery Protocol had its origin in the SynOptics Network Management Protocol (SONMP), developed before the SynOptics and Wellfleet Communications merger in 1994. The protocol was rebranded as the Bay Network Management Protocol (BNMP) and some protocol analyzers referenced it as the ''Bay Discovery Protocol'' (BDP). Four years later, in 1998, Bay Networks was acquired by Nortel and renamed it to Nortel Discovery Protocol. The IEEE 802.1AB or Link Layer Discovery Protocol The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally ...

Nortel Networks
Nortel Networks Corporation (Nortel), formerly Northern Telecom Limited, was a Canadian multinational telecommunications and data networking equipment manufacturer headquartered in Ottawa, Ontario, Canada. It was founded in Montreal, Quebec, in 1895 as the Northern Electric and Manufacturing Company. Until an antitrust settlement in 1949, Northern Electric was owned principally by Bell Canada and the Western Electric Company of the Bell System, producing large volumes of telecommunication equipment based on licensed Western Electric designs. At its height, Nortel accounted for more than a third of the total valuation of all companies listed on the Toronto Stock Exchange (TSX), employing 94,500 people worldwide. In 2009, Nortel filed for bankruptcy protection in Canada and the United States, triggering a 79% decline of its corporate stock price. The bankruptcy case was the largest in Canadian history and left pensioners, shareholders and former employees with enormous losse ...

Ungermann-Bass
Ungermann-Bass, 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 competitor 3Com, 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/IP as it became an i ...

Mission College (Santa Clara, California)
Mission College (Mission or MC) is a public community college in Santa Clara, California. It is part of the West Valley–Mission Community College District. The land the college is on was bought between 1966 and 1967. Mission College opened for its first year in 1975. In 1979 it had grown to "3,500 students, 8 administrators, and 73 instructors". History The Mission College Interim Campus was housed on the site of the vacant Jefferson Middle School at the corner of Monroe Street and Lawrence Express in Santa Clara, California in early September, 1975. From this humble beginning, three members originally appointed for full-time duty—Teri Chiang (Mathematics), Don Joslen (Fine Arts), and Son Le (Philosophy)) worked with Administrator Burt Hermosillo with the support of several part-time faculty volunteers from West Valley College to offer morning and evening classes. By summer, 1976, the Governing Board had appointed Warren Sorenson as founding president. Mission College's fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Billerica, Massachusetts
Billerica (, ) is a town in Middlesex County, Massachusetts, United States. The population was 42,119 according to the 2020 census. It takes its name from the town of Billericay in Essex, England. History In the early 1630s, a Praying Indian village named Shawshin was at the current site of Billerica, commonly spelled Shawsheen today, as in the Shawsheen River. In 1638, Massachusetts Bay Governor John Winthrop and Lt. Governor Thomas Dudley were granted land along the Concord River in the area, and roughly a dozen families from Cambridge and Charlestown Village had begun to occupy Shawshin by 1652. The settlers chose the name Billerica because some of the families originally came from the town of Billericay in Essex, England. The town was incorporated as Billerica in 1655, on the same day as neighboring Chelmsford and nearby Groton. The original plantation of Billerica was divided during the colonial period into the towns of Billerica, Bedford, Wilmington, and Tewksbury. ...
