Proteon
Proteon, Inc. was a pioneering designer and manufacturer computer network equipment based in Westborough, Massachusetts. Proteon created the first commercial Token Ring products and created the first commercially available multiprotocol Internet router as well as the OSPF routing protocol. History Proteon designed and manufactured of some of the earliest commercial Local Area Network and TCP/IP Internet Router products. Although founded in 1972 by Howard Salwen as communications consulting firm, Proteon became a manufacturer when they produced the first commercial Token Ring network interfaces and media access units in conjunction with MIT. In 1981, they released the 10Mbit/sec Pronet-10 Token Ring network. and evolved the speeds through 16 MBit/sec, 80 Mbit/sec and 100 Mbit/sec. IBM released a competing Token Ring system in 1984. In 1986, Proteon released the first commercially available multi-protocol router, the p4200, based on the MIT multi-protocol router, using code devel ...

Token Ring
Token Ring network IBM hermaphroditic connector with locking clip. Screen contacts are prominently visible, gold-plated signal contacts less so. Token Ring is a computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a ''token'' that is passed around a logical ''ring'' of workstations or servers. This token passing is a channel access method providing fair access for all stations, and eliminating the collisions of contention-based access methods. Token Ring was a successful technology, particularly in corporate environments, but was gradually eclipsed by the later versions of Ethernet. History A wide range of different local area network technologies were developed in the early 1970s, of which one, the Cambridge Ring, had demonstrated the potential of a token passing ring topology, and many teams worldwide began working on their own implementations. ...

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 ...

Wellfleet Communications
Wellfleet Communications was an Internet Router (computing), router company founded in 1986 by Paul Severino, Bill Seifert, Steven Willis and David Rowe based in Bedford, Massachusetts, and later Billerica, Massachusetts. In an attempt to more effectively compete with Cisco Systems, its chief rival, it merged in October, 1994 with SynOptics Communications of Santa Clara, California to form Bay Networks in a deal worth US$ 2.7B. Bay Networks would in turn be acquired by Nortel in June, 1998 for US$ 9.1B. Wellfleet was ranked the fastest-growing company in the United States by Fortune (magazine), Fortune Magazine in both 1992 and 1993. Wellfleet sold routers.

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...

TCP/IP
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). In the development of this networking model, early versions of it were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westborough, Massachusetts
Westborough is a town in Worcester County, Massachusetts, United States. The population was 21,567 at the 2020 Census, in over 7,000 households. Incorporated in 1717, the town is governed under the New England open town meeting system, headed by a five-member elected Board of Selectmen whose duties include licensing, appointing various administrative positions, and calling a town meeting of citizens annually or whenever the need arises. History Before recorded time, the area now known as Westborough was a well-travelled crossroads. As early as 7,000 BCE, prehistoric people in dugout canoes followed the Sudbury and Assabet Rivers to their headwaters in search of quartzite for tools and weapons. From 1200 to 1600 CE, seasonal migrations brought Nipmuc Indians to hunt and fish near Cedar Swamp and Lake Hoccomocco. Using Fay Mountain as a landmark, Indians crisscrossed Westborough on well-worn paths: the old Connecticut Path leading west from Massachusetts Bay; the Narraganse ...
