Local Area Transport
Local Area Transport (LAT) is a non-routable (data link layer) networking technology developed by Digital Equipment Corporation to provide connection between the DECserver terminal servers and Digital's VAX and Alpha and MIPS host computers via Ethernet, giving communication between those hosts and serial devices such as video terminals and printers. The protocol itself was designed in such a manner as to maximize packet efficiency over Ethernet by bundling multiple characters from multiple ports into a single packet for Ethernet transport. One ''LAT'' strength was efficiently handling time-sensitive data transmission. Over time, other host implementations of the LAT protocol appeared allowing communications to a wide range of Unix and other non-Digital operating systems using the LAT protocol. History In 1984, the first implementation of the LAT protocol connected a terminal server to a VMS VAX-Cluster in Spit Brook Road, Nashua, NH. By "virtualizing" the terminal port at the h ...

Digital News
Digital News was a trade publication that focused on products from Digital Equipment Corporation (DEC). History They published independently from 1986 thru 1992. At that point, they were acquired and merged with '' Digital Review'' with the new title ''Digital News & Review''. ''DEC'' product news and reviews from Sonny Monosson, which were featured on the ''Digital Business'' pages of ''Digital News'' were retained in the pages of ''Digital News & Reviews''. The Boston Globe had described the situation between the prior publication owners as "The war among the Digitals: Bitter competition reflects growing rivalry between Ziff, McGovern empires." The combined ''Digital News & Review'' periodical was printed from 1992 to 1996 by Reed Business Information. ''Hardcopy'' (magazine) In 1988, ''Digital News'' acquired 1980-founded ''Hardcopy'' magazine (stylized ''HARDCOPY''). At the time, International Data Group International Data Group (IDG, Inc.) is a market intelligence and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminal Emulator
A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term ''terminal'' covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window. A terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications. These may be running either on the same machine or on a different one via telnet, ssh, dial-up, or over a direct serial connection. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine. Terminals usually support a set of escape sequences for controlling color, cursor position, etc. Examples include the family of terminal control sequence standards known as ECMA-48, ANSI X3.64 or ISO/IEC 6 ...

Console Server
A terminal server connects devices with a serial port to a local area network (LAN). Products marketed as terminal servers can be very simple devices that do not offer any security functionality, such as data encryption and user authentication. The primary application scenario is to enable serial devices to access network server applications, or vice versa, where security of the data on the LAN is not generally an issue. There are also many terminal servers on the market that have highly advanced security functionality to ensure that only qualified personnel can access various servers and that any data that is transmitted across the LAN, or over the Internet, is encrypted. Usually, companies that need a terminal server with these advanced functions want to remotely control, monitor, diagnose and troubleshoot equipment over a telecommunications network. A console server (also referred to as console access server, console management server, serial concentrator, or serial console ...

Local Area Network
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. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring and AppleTalk. History The increasing demand and usage 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. Ethe ...

Package Manager
A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs for a computer in a consistent manner. A package manager deals with ''packages'', distributions of software and data in archive files. Packages contain metadata, such as the software's name, description of its purpose, version number, vendor, checksum (preferably a cryptographic hash function), and a list of dependencies necessary for the software to run properly. Upon installation, metadata is stored in a local package database. Package managers typically maintain a database of software dependencies and version information to prevent software mismatches and missing prerequisites. They work closely with software repositories, binary repository managers, and app stores. Package managers are designed to eliminate the need for manual installs and updates. This can be particularly useful for large enterp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Distributions
A Linux distribution (often abbreviated as distro) is an operating system made from a software collection that includes the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices (for example, OpenWrt) and personal computers (for example, Linux Mint) to powerful supercomputers (for example, Rocks Cluster Distribution). A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System, or, more recently, Wayland), a window manager, and a desktop environment. Most of the included software is free and open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Usually, Linux distributions optionally include some proprietary sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interlink Computer Sciences
Interlink Computer Sciences, of Fremont, California, was a developer of hardware and software that allowed IBM mainframe computers running the MVS operating system to be connected to non-IBM networks. Interlink was founded in 1983 by Lambert Onuma, Fred Wright, Karl Johnson and Greg Thompson, formerly of Digital Equipment Corporation. The company's first product, called simply ''Interlink'', allowed IBM MVS mainframes to be connected to VAX computers on a DECnet network. Later a VM/DECnet product was developed in cooperation with Dupont to link IBM VM/CMS systems with a DECnet network interconnecting e-mail, file, tape, and storage access, terminal emulation, a program-to-program API, and enabling DECnet to be tunneled over an SNA LU6.2 network. In 1990, Interlink acquired a product called ''ACCES/MVS'' from Advanced Computer Communications, which implemented a native TCP/IP protocol stack on the MVS and VM operating systems and within CICS regions. First released in 1986, A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hughes LAN Systems
Sytek, known as Hughes LAN Systems (HLS) after being acquired by Hughes Electronics and known as Whittaker Communications (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. During this crucial period in 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 RF transceiver that operated on cable TV frequencies. It received in the High VHF band and transmitted in the Low VHF band. These bands were referred to as the forward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Datability
Penril DataComm Networks, Inc. was a computer telecommunications hardware company that made some acquisitions and was eventually split into two parts: one was acquired by Bay Networks and the other was a newly formed company named Access Beyond. The focus of both company's products was end-to-end data transfer. By the mid-1990s, with the popularization of the internet, this was no longer of wide interest. History Penril, whose earnings reports and other financials were followed by The New York Times in the 1990s, made several acquisitions but also grew internally. Following its Datability acquisition it renamed itself Penril Datability Networks. By the time the 1968-founded Penril was acquired by Bay their name was Penril DataComm Networks. The company, which as of 1985 "had made 14 acquisitions in 12 years," also had done extensive work regarding quality control, and leveraged their product line by what The Washington Post called clever packaging: "software, cables, instructio ...

Emulex Corporation
Emulex Corporation is a provider of computer network connectivity, monitoring and management hardware and software. The company's I/O connectivity offerings, including its line of Ethernet and Fibre Channel-based connectivity products, are or were used in server and storage products from OEMs, including Cisco, Dell, EMC Corporation, Fujitsu, Hitachi, HP, Huawei, IBM, NetApp, and Oracle Corporation. History 1979–1999 Emulex was founded in 1979 by Fred B. Cox "as a supplier of data storage products and data communications equipment for the computer industry." By 1983, Emulex was able to advertise its products as if grocery items: a 2-page spread headlined "One stop shopping for VAX users? Emulex, of course" showed 3 paper bags, each with the Emulex name and logo and each holding a large computer board. One bag also said "''Disk Controllers''" while the second bag said "''Communication Controllers'';" the third said "''Tape Controllers''." In 1992 ''Emulex'' spun off what ...
