Dialcom
Dialcom Inc. was a United States corporation which developed the world's first commercial electronic mail service. It was founded in 1970 by Robert F. Ryan and was sold to ITT Corporation in 1982, becoming ITT Dialcom. Dialcom's e-mail software ran on Prime minicomputers and was licensed to governmental telecommunications providers in over seventeen countries. Various extra features could be offered by Dialcom-based services, including gateways to telex and fax, and online information retrieval services. In 1986, British Telecom, who used Dialcom software for its Telecom Gold service, bought Dialcom from ITT. Dialcom systems Each Dialcom system was allocated a two-digit identification number. This was used as a prefix for the Dialcom e-mail addresses (or "mailboxes"), thus allowing e-mail to be exchanged between different Dialcom services. By 1990, the following Dialcom systems were operating: Time-sharing service Dialcom began as computer time-sharing services. A user would sig ...

Telecom Gold
Telecom Gold (sometimes also known as BT Gold) was an early commercial electronic mail service launched by British Telecom in 1982. It was based on Prime minicomputers running Dialcom software under a customised version of PRIMOS. (ITT Dialcom was later acquired by BT in 1986.) The system offered various services, including e-mail to and from other Telecom Gold users and those of Dialcom services in other countries, and other e-mail systems such as Sprint and integration with telex, fax, online databases and an experimental OCR system for a short while. Later, X.400 functionality was added. Users would dial into the system using a conventional modem and terminal emulator. Alternatively, users could dial a local number and connect via the PSS X.25 network. The X.400 services also had a Mail User Agent which ran on IBM PCs and compatibles. The UK data centre was originally located in the basement of Beckett House 60-68 St Thomas St, Bermondsey, London, SE1 3QU but later moved to ...

Technology Companies Disestablished In 1982
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to economic de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time-sharing Companies
In computing, time-sharing is the sharing of a computing resource among many users at the same time by means of multiprogramming and multi-tasking.DEC Timesharing (1965), by Peter Clark, The DEC Professional, Volume 1, Number 1 Its emergence as the prominent model of computing in the 1970s represented a major technological shift in the history of computing. By allowing many users to interact concurrently with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one, and promoted the interactive use of computers and the development of new interactive applications. History Batch processing The earliest computers were extremely expensive devices, and very slow in comparison to later models. Machines were typically dedicated to a particular set of tasks and operated by control panels, the operator manually entering small programs via switches in order ...

Internet In The United States
The Internet in the United States grew out of the ARPANET, a network sponsored by the Advanced Research Projects Agency of the U.S. Department of Defense during the 1960s. The Internet in the United States in turn provided the foundation for the worldwide Internet of today. Internet connections in the United States are largely provided by the private sector and are available in a variety of forms, using a variety of technologies, at a wide range of speeds and costs. In 2019, the United States ranked 3rd in the world for the number of internet users (behind China and India), with 312.32 million users. As of 2019, 90% of adults in America use the internet, either irregularly or frequently. The United States ranks #1 in the world with 7,000 Internet Service Providers (ISPs) according to the CIA. Internet bandwidth per Internet user was the 43rd highest in the world in 2016. Internet top-level domain names specific to the U.S. include .us, .edu, .gov, .mil, .as (American Samoa) ...

Telecommunications Companies Established In 1970
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

History Of Telecommunications In The United States
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Email
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simu ...
