A bulletin board system (BBS), also called a 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 performs 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.
Fax, sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material, normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine, which processes the contents as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines transmit an audio-encoded digital representation of the page, using data compression to transmit areas that are all-white or all-black, more quickly.
Digital subscriber line is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure. Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet, taking advantage of the high bandwidth of a HFC and RFoG network. They are commonly deployed in the Americas, Asia, Australia, and Europe.
Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line which could be connected using an RJ-11 connector. Dial-up connections use modems to decode audio signals into data to send to a router or computer, and to encode signals from the latter two devices to send to another modem at the ISP.
The Hayes command set is a specific command language originally developed by Dale Heatherington and Dennis Hayes for the Hayes Smartmodem in 1981.
U.S. Robotics Corporation, often called USR, is a company that produces USRobotics computer modems and related products. Its initial marketing was aimed at bulletin board systems, where its high-speed HST protocol made FidoNet transfers much faster, and thus less costly. During the 1990s it became a major consumer brand with its Sportster line. The company had a reputation for high quality and support for the latest communications standards as they emerged, notably in its V.Everything line, released in 1996.
Charter Communications, Inc., is an American telecommunications and mass media company with services branded as Spectrum. The company is headquartered in Stamford, Connecticut.
A residential gateway is a small consumer-grade gateway which bridges network access between connected local area network (LAN) hosts to a wide area network (WAN) via a modem, or directly connects to a WAN, while routing. The WAN is a larger computer network, generally operated by an Internet service provider.
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 of America in turn provided the foundation for the worldwide Internet of today.
Snapdragon is a suite of system-on-chip (SoC) semiconductor products for mobile devices designed and marketed by Qualcomm, who often refers to these SoCs as "mobile platforms". They typically integrate central processing units (CPU) based on the ARM architecture, a graphics processing unit (GPU), some digital signal processors (DSP), and may or may not include a cellular modem. Snapdragon semiconductors are designed for embedded systems, e.g., smartphones, netbooks, and vehicles. In addition to the processors, the lineup also includes modems, Wi-Fi chips and mobile charging products.
A modulator-demodulator, commonly referred to as a modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from LEDs to radio.
The Timex Sinclair 2050 (TS2050) was a computer modem built by Westridge Communications for Timex Sinclair, a joint venture between Sinclair Research and Timex Corporation.
The BT Voyager series is a series of ADSL modems supplied by British Telecommunications plc. Several models include WiFi, routing and voice over IP capabilities.
Intel Mobile Communications (IMC), is the mobile research and development division of Intel. It was formed when Intel completed the acquisition of the Wireless Solutions (WLS) division of Infineon early in 2011 for US$1.4 billion. The Infineon subsidiary Comneon was also acquired by Intel and integrated into Intel Mobile Communications. IMC maintained offices in Munich from the Comneon deal under Intel Mobile Communications GmbH. Some other offices in Germany were closed in 2015.
The Samsung Exynos, formerly Hummingbird (Korean: 엑시노스), is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Foundry. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs.
The Goods and Services Tax (GST) is a successor to VAT used in India on the supply of goods and service. Both VAT and GST have the same taxation slabs. It is a comprehensive, multistage, destination-based tax: comprehensive because it has subsumed almost all the indirect taxes except a few state taxes. Multi-staged as it is, the GST is imposed at every step in the production process, but is meant to be refunded to all parties in the various stages of production other than the final consumer and as a destination-based tax, it is collected from point of consumption and not point of origin like previous taxes.
