Diversi-Dial
Diversi-Dial, or DDial was an online chat server that was popular during the mid-1980s. It was a specialized type of bulletin board system that allowed all callers to send lines of text to each other in real-time, often operating at 300 baud. In some ways, it was a sociological forerunner to IRC, and was a cheap, local alternative to CompuServe chat, which was expensive and billed by the minute. At its peak, at least 35 major DDial systems existed across the United States, many of them in large cities. During the evening when telephone rates were low, the biggest DDial systems would link together using Telenet or PC Pursuit connections, forming regional chat networks. History Diversi-Dial was written by Bill Basham, a computer hobbyist who ran a company known as Diversified Software Research in Farmington Hills, Michigan. The software was written while he was a resident of Rockford, Illinois. Bill Basham ran a copy of the system himself in Rockford at the time. Kim Ki ...

Synergy Teleconferencing System
{{Unreferenced, date=December 2009 Synergy Teleconferencing System (STS) was a PC-based online chat server popular in the 1980s and 1990s. It arose as a replacement for the outdated Diversi-Dial system (DDial). Like DDial, it was a multi-line modem system that originally could handle eight simultaneous connections (later updated to handle twenty eight, and using custom-produced RS-232 serial boards had a theoretical connection limit of thirty-two on an IBM PC-AT - type computer (80286 processor). While DDial was limited to 300 baud, STS was initially capable of 2400 baud speeds (later editions upped this to 14.4, 19.2, and 28.8). Using internal software, one or more of these lines could be used to establish links to other STS stations, effectively making the number of simultaneous users dependent on how many STSes were involved. The interface and design was similar to DDial in that users logged into the system with a three digit number that served as a username. Once logged in, ...

Sysop
A sysop (; an abbreviation of system operator) is an administrator of a multi-user computer system, such as a bulletin board system (BBS) or an online service virtual community.Jansen, E. & James,V. (2002). NetLingo: the Internet dictionary. Netlingo Inc., Oxnard, CA The phrase may also be used to refer to administrators of other Internet-based network services.Rhodes, D. & Butler, D. (2002). Solaris Operating Environment Boot Camp. Prentice Hall Professional. Sysops typically do not earn money, but donate their activity to the community. Co-sysops are users who may be granted certain admin privileges on a BBS. Generally, they help validate users and monitor discussion forums. Some co-sysops serve as file clerks, reviewing, describing, and publishing newly uploaded files into appropriate download directories.Gupta, A. (2004). Hacking In The Computer World. Mittal Publications. Historically, the term ''system operator'' applied to operators of any computer system, especially a m ...

Telnet
Telnet is an application protocol used on the Internet or local area network to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). Telnet was developed in 1969 beginning with , extended in , and standardized as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the first Internet standards. The name stands for " teletype network". Historically, Telnet provided access to a command-line interface on a remote host. However, because of serious security concerns when using Telnet over an open network such as the Internet, its use for this purpose has waned significantly in favor of SSH. The term ''telnet'' is also used to refer to the software that implements the client part of the protocol. Telnet client applications are available for virtually all c ...

Apple //e
The Apple IIe (styled as Apple //e) is the third model in the Apple II series of personal computers produced by Apple Computer. The ''e'' in the name stands for ''enhanced'', referring to the fact that several popular features were now built-in that were formerly only available as upgrades or add-ons in earlier models. Improved expandability combined with the new features made for a very attractive general-purpose machine to first-time computer shoppers. As the last surviving model of the Apple II computer line before discontinuation, and having been manufactured and sold for nearly 11 years with relatively few changes, the IIe earned the distinction of being the longest-lived computer in Apple's history. History Apple Computer planned to discontinue the Apple II series after the introduction of the Apple III in 1980; the company intended to clearly establish market segmentation by designing the Apple III to appeal to the business market, leaving the Apple II for home and educat ...

Bulletin Board System
A bulletin board system (BBS), also called computer bulletin board service (CBBS), is a computer server running software that allows users to connect to the system using a terminal program. Once logged in, the user can perform functions such as uploading and downloading software and data, reading news and bulletins, and exchanging messages with other users through public message boards and sometimes via direct chatting. In the early 1980s, message networks such as FidoNet were developed to provide services such as NetMail, which is similar to internet-based email. Many BBSes also offer online games in which users can compete with each other. BBSes with multiple phone lines often provide chat rooms, allowing users to interact with each other. Bulletin board systems were in many ways a precursor to the modern form of the World Wide Web, social networks, and other aspects of the Internet. Low-cost, high-performance asynchronous modems drove the use of online services and BBSes t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

GEnie
Jinn ( ar, , ') – also romanized as djinn or anglicized as genies (with the broader meaning of spirit or demon, depending on sources) – are invisible creatures in early pre-Islamic Arabian religious systems and later in Islamic mythology and theology. Like humans, they are accountable for their deeds, can be either believers (''Muslim'') or unbelievers (''kafir''); depending on whether they accept God's guidance. Since jinn are neither innately evil nor innately good, Islam acknowledged spirits from other religions and was able to adapt spirits from other religions during its expansion. Jinn are not a strictly Islamic concept; they may represent several pagan beliefs integrated into Islam. To assert a strict monotheism and the Islamic concept of ''Tauhid'', Islam denies all affinities between the jinn and God, thus placing the jinn parallel to humans, also subject to God's judgment and afterlife. The Quran condemns the pre-Islamic Arabian practise of worshipping the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PC
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by Don Estridge in Boca Raton, Florida. The machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from the Apple Macintosh product line. The majority of modern personal computers are distant descendants of the IBM PC. History Prior to the 1980s, IBM had largely been known as a provider of business computer systems. As the 1980s opened, their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple II
The Apple II (stylized as ) is an 8-bit home computer and one of the world's first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak; Jerry Manock developed the design of Apple II's foam-molded plastic case, Rod Holt developed the switching power supply, while Steve Jobs's role in the design of the computer was limited to overseeing Jerry Manock's work on the plastic case. It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire, and marks Apple's first launch of a personal computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists. ''Byte'' magazine referred to the Apple II, Commodore PET 2001, and TRS-80 as the "1977 Trinity". As the Apple II had the defining feature of being able to display color graphics, the Apple logo was redesigned to have a spectrum of colors. The Apple II is the first model in the Apple II series, followed by Apple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Cluster
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. Computer clusters emerged as a result of convergence of a number of computing trends including t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
