Compuserve
CompuServe (CompuServe Information Service, also known by its initialism CIS) was an American online service provider, the first major commercial one in the world – described in 1994 as "the oldest of the Big Three information services (the others are Prodigy and America Online)." It dominated the field during the 1980s and remained a major influence through the mid-1990s. At its peak in the early 1990s, CIS was known for its online chat system, message forums covering a variety of topics, extensive software libraries for most computer platforms, and a series of popular online games, notably ''MegaWars III'' and ''Island of Kesmai''. It also was known for its introduction of the GIF format for pictures and as a GIF exchange mechanism. In 1997, 17 years after H&R Block had acquired CIS, the parent announced its desire to sell the company. A complex deal was worked out with WorldCom acting as a broker, resulting in CIS being sold to AOL. In 2015, Verizon acquired AOL, includi ...

Online Service Provider
An online service provider (OSP) can, for example, be an Internet service provider, an email provider, a news provider (press), an entertainment provider (music, movies), a search engine, an e-commerce site, an online banking site, a health site, an official government site, social media, a wiki, or a Usenet newsgroup. In its original more limited definition, it referred only to a commercial computer communication service in which paid members could dial via a computer modem the service's private computer network and access various services and information resources such as bulletin board systems, downloadable files and programs, news articles, chat rooms, and electronic mail services. The term "online service" was also used in references to these dial-up services. The traditional dial-up online service differed from the modern Internet service provider in that they provided a large degree of content that was only accessible by those who subscribed to the online service, while ...

Island Of Kesmai
''Island of Kesmai'' was an early commercial online game in the multi-user dungeon (MUD) genre, innovative in its use of roguelike pseudo-graphics.

For its initial roll-out, Prodigy used 1,200 bit/s modem connections. To provide faster service and to stabilize the diverse modem market, Prodigy offered low-cost 2,400 bit/s internal modems to subscribers at a discount. The host systems used were regionally distributed IBM Series/1 minicomputers managed by central IBM mainframes located in Yorktown Heights, New York. The co ...

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 ...

CB Simulator
CompuServe CB Simulator was the first dedicated online chat service that was widely available to the public. It was developed by a CompuServe executive, Alexander "Sandy" Trevor, and released by CompuServe on February 21, 1980, as the first public, commercial multi-user chat program. At that time, most people were familiar with citizens band radio, often abbreviated as CB radio, but multi-user chat and instant messaging were largely unknown. CompuServe CB used the CB radio paradigm to help users understand the new concept. Like CB radio it had 40 "channels" and commands like "tune", "squelch", and "monitor". CompuServe CB quickly became the largest single product on CompuServe despite virtually no marketing. When 40 channels was not enough, additional "bands" were added, such as the "Adult" band. The first online wedding occurred on CompuServe CB, and worldwide fans organized events to meet in the "real world" people they had met in CB. Compuserve's CBIG (CB Interest Group) Sysop ...

PDP-10
Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family manufactured beginning in 1966 and discontinued in 1983. 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. The PDP-10's architecture is almost identical to that of DEC's earlier PDP-6, sharing the same 36-bit word length and slightly extending the instruction set (but with improved hardware implementation). Some aspects of the instruction set are unusual, most notably the ''byte'' instructions, which operate on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as ''a contiguous sequence of a fixed number of bits''. The PDP-10 was found in many university computing facilities and research labs during the 1970s, the most notable being Harvard University's Aiken Computation Laboratory, MIT's AI Lab and Project MAC, Stanford's SAIL, Computer ...

Midrange Computer
Midrange computers, or midrange systems, were a class of computer systems that fell in between mainframe computers and microcomputers. This class of machine emerged in the 1960s, with models from Digital Equipment Corporation ( PDP line), Data General ( NOVA), Hewlett-Packard ( HP3000) widely used in science and research as well as for business - and referred to as minicomputers. IBM favored the term "midrange computer" for their comparable, but more business-oriented systems. IBM Midrange Systems * System/3 was the first IBM midrange system (1969) * System/32 (introduced in 1975) was a 16-bit single-user system also known as the IBM 5320. * System/34 (1977) was intended to be a successor to both the 3 and the 32. * System/38 (1979) was the first midrange system to have an integrated relational database management system (DBMS). The S/38 had 48-bit addressing, and ran the CPF operating system. * System/36 (1983) had two 16-bit processors with an operating system that ...

Business Hours
Business hours are the hours during the day in which business is commonly conducted. Typical business hours vary widely by country. By observing common informal standards for business hours, workers may communicate with each other more easily and find a convenient divide between work life and home life. In Australia, Canada, New Zealand, the United Kingdom, and the United States, the hours between 9 am and 5 pm (the traditional " 9 to 5") are typically considered to be standard business hours. However, U.S. governmental agencies typically operate between the hours of 7:00am and 3:00pm. As one employee put it: “There’s nothing more standard than the government.” The topic of standard hours is hotly debated in modern times. In Finland, government agencies and other institutions follow the hours 8:00am to 4:15pm. Banks are usually open to 4:30pm. Common business is done from Monday to Friday, but major shops are usually open on Saturdays 9:00am – 6:00pm and on Sundays ...

Control Data Corporation
Control Data Corporation (CDC) was a mainframe and supercomputer firm. CDC was one of the nine major United States computer companies through most of the 1960s; the others were IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well-known and highly regarded throughout the industry at the time. For most of the 1960s, Seymour Cray worked at CDC and developed a series of machines that were the fastest computers in the world by far, until Cray left the company to found Cray Research (CRI) in the 1970s. After several years of losses in the early 1980s, in 1988 CDC started to leave the computer manufacturing business and sell the related parts of the company, a process that was completed in 1992 with the creation of Control Data Systems, Inc. The remaining businesses of CDC currently operate as Ceridian.
