區域網
Local area network

context: zh_tw: 區域網（Local Area Network (LAN)）是一個可連線住宅，學校，實驗室，大學校園或辦公大樓等有限區域內計算機的計算機網路 。相比之下，廣域網（WAN）不僅覆蓋較大的地理距離，而且還通常涉及固接專線和對於網際網路的連結。 相比來說網際網路則更為廣闊，是連線全球商業和個人電腦的系統。
en: A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.

context: zh_tw: 對於與 NetWare 的同期競爭者，只有 Banyan Vines 有與之媲美的技術水平，但 Banyan 卻未獲得安全許可權（？）。 微軟與 3Com 合作完成了一個簡單的網路作業系統，也就是後來 3Com's 的 3+Share，Microsoft 的 LAN Manager 以及 IBM 的 LAN Server 各家的原型，但這些都沒達到既定目標。
en: The increasing demand and use of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation.A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethernet was developed at Xerox PARC between 1973 and 1974. ARCNET was developed by Datapoint Corporation in 1976 and announced in 1977. It had the first commercial installation in December 1977 at Chase Manhattan Bank in New York.The development and proliferation of personal computers using the CP/M operating system in the late 1970s, and later DOS-based systems starting in 1981, meant that many sites grew to dozens or even hundreds of computers. The initial driving force for networking was to share storage and printers, both of which were expensive at the time. There was much enthusiasm for the concept, and for several years, from about 1983 onward, computer industry pundits would regularly declare the coming year to be, "The year of the LAN".In practice, the concept was marred by proliferation of incompatible physical layer and network protocol implementations, and a plethora of methods of sharing resources. Typically, each vendor would have its own type of network card, cabling, protocol, and network operating system. A solution appeared with the advent of Novell NetWare which provided even-handed support for dozens of competing card and cable types, and a much more sophisticated operating system than most of its competitors. Netware dominated the personal computer LAN business from early after its introduction in 1983 until the mid-1990s when Microsoft introduced Windows NT.Of the competitors to NetWare, only Banyan Vines had comparable technical strengths, but Banyan never gained a secure base. 3Com produced 3+Share  and Microsoft produced MS-Net. These then formed the basis for collaboration between Microsoft and 3Com to create a simple network operating system LAN Manager and its cousin, IBM's LAN Server. None of these enjoyed any lasting success.

context: zh_tw: 同一時間， Unix 工作站使用 TCP/IP 協議族網路，雖然至今市場份額有限，但其相關技術對 Linux 和蘋果 Mac OS X 的網路有著不可或缺的影響力 —— 況且 TCP/IP 協議早已取代 網際網路分組交換協議（IPX）, AppleTalk，與 NetBIOS Frames 協定（NBF）等其他協議並應用於早期的區域網範疇。
en: During the same period, Unix workstations were using TCP/IP networking. Although this market segment is now much reduced, the technologies developed in this area continue to be influential on the Internet and in both Linux and Apple Mac OS X networking—and the TCP/IP protocol has replaced IPX, AppleTalk, NBF, and other protocols used by the early PC LANs.
