JANET NRS
The JANET NRS (''Name Registration Scheme'') was a pseudo-hierarchical naming scheme used on British academic and research networks in the 1980s. It used a reverse domain name notation. History It was proposed in 1983 and used until the superficially similar Internet Domain Name System was fully adopted. Structure The NRS " second-level domains" consisted of (JANET academic and scientific sites), (commercial) and (Ministry of Defence). Any organisations not falling into these categories were given their own "second-level" name, e.g. (British Library) or ( National Engineering Laboratory). All NRS names had both a ''standard'' (long) and ''abbreviated'' (up to 18 characters) form. For example, was the less widely used standard equivalent of the abbreviated name . For email, interoperability between the " Grey Book" email addressing style of and ARPA and USENET addresses of the style was achieved by way of mail gateway at University College London.

Non-Internet Email Address
A wide variety of non-Internet email address formats were used in early email systems before the ubiquity of the ''john.smith@example.com'' form used by Internet mail systems since the 1980s - and a few are still used in specialised contexts. Single system The earliest email addresses simply had to identify one user from another on one homogenous system, often a single host minicomputer or mainframe. They were therefore typically the user's login name on that system. Examples of this style include: * ATS: ''123'' * CompuServe: ''432654,6564'' * MCI Mail: ''373-1994'' * AOL: ''Steve Case'' At a host As computer systems became networked email addresses needed to be able to identify not only the user, but also which host or mail system they were on. Addresses of this type were used in a number of early email systems, including: * ARPANET: ''jim@washington'' * PROFS: ''userid@node'' * DECnet: ''host::user'' (e.g. DECWRL::WRL-TECHREPORTS) * cc:Mail: ''John Alexopoulos at MicroC ...

Internet In The United Kingdom
The United Kingdom has been involved with the Internet throughout its origins and development. The telecommunications infrastructure in the United Kingdom provides Internet access to businesses and home users in various forms, including fibre, cable, DSL, wireless and mobile. The share of households with Internet access in the United Kingdom grew from 9 percent in 1998 to 93 percent in 2019. Virtually all adults aged 16 to 44 years in the UK were recent internet users (99%) in 2019, compared with 47% of adults aged 75 years and over; in aggregate, the third-highest in Europe. Online shoppers in the UK spend more per household than consumers in any other country. Internet bandwidth per Internet user was the seventh highest in the world in 2016, and average and peak internet connection speeds were top-quartile in 2017. Internet use in the United Kingdom doubled in 2020. The Internet country code top-level domain (ccTLD) for the United Kingdom is .uk and is run by Nominet. ...

Coloured Book Protocols
The Coloured Book protocols were a set of communication protocols for computer networks developed in the United Kingdom in the 1970s. The name originated with each protocol being identified by the colour of the cover of its specification document. The protocols were in use until the 1990s when the Internet protocol suite came into widespread use. History First defined in 1975, they evolved through experience with the Experimental Packet Switched Service run by Post Office Telecommunications beginning in 1977. They were used on the SERCnet from 1980, and SWUCN from 1982, both of which became part of the JANET academic network from 1984. The protocols gained some acceptance internationally as the first complete X.25 standard, and gave the UK "several years lead over other countries". From late 1991, Internet protocols were adopted on the Janet network instead; they were operated simultaneously for a while, until X.25 support was phased out entirely in August 1997. Protoco ...

ISO 3166
ISO 3166 is a standard published by the International Organization for Standardization (ISO) that defines codes for the names of countries, dependent territories, special areas of geographical interest, and their principal subdivisions (e.g., provinces or states). The standard employs a code of letters and numbers to represent the name of a given geographical area in order to save time and energy when describing the area, as well as to reduce the risk of description errors. The official name of the standard is ''Codes for the representation of names of countries and their subdivisions''. Parts It consists of three parts: * ISO 3166-1, ''Codes for the representation of names of countries and their subdivisions – Part 1: Country codes'', defines codes for the names of countries, dependent territories, and special areas of geographical interest. It defines three sets of country codes: ** ISO 3166-1 alpha-2 – two-letter country codes which are the most widely used of the ...

Country Code Top-level Domain
A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs. In 2018, the Internet Assigned Numbers Authority (IANA) began implementing internationalized country code top-level domains, consisting of language-native characters when displayed in an end-user application. Creation and delegation of ccTLDs is described in RFC 1591, corresponding to ISO 3166-1 alpha-2 country codes. While gTLDs have to obey international regulations, ccTLDs are subjected to requirements that are determined by each country’s domain name regulation corporation. With over 150 million domain name registrations today or as of 2022, ccTLDs make up about 40% of the total domain name industry. Country code extension applications began in 1985.

Internet Protocols
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] |

Big-endian
In computing, endianness, also known as byte sex, is the order or sequence of bytes of a word of digital data in computer memory. Endianness is primarily expressed as big-endian (BE) or little-endian (LE). A big-endian system stores the most significant byte of a word at the smallest memory address and the least significant byte at the largest. A little-endian system, in contrast, stores the least-significant byte at the smallest address. Bi-endianness is a feature supported by numerous computer architectures that feature switchable endianness in data fetches and stores or for instruction fetches. Other orderings are generically called middle-endian or mixed-endian. Endianness may also be used to describe the order in which the bits are transmitted over a communication channel, e.g., big-endian in a communications channel transmits the most significant bits first. Bit-endianness is seldom used in other contexts. Etymology Danny Cohen introduced the terms ''big-endian'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
