A communications satellite (sometimes abbreviated to comsat) is an artificial satellite stationed in space for the purposes of telecommunications. Modern communications satellites use geosynchronous orbits, Molniya orbits or low polar Earth orbits.

For fixed services, communications satellites provide a technology complementary to that of fiber optic submarine communication cables. They are also used for mobile applications such as communications to ships and planes, for which application of other technologies, such as cable, are impractical or impossible.

Packet switching, in computer networking and telecommunications, is the now-dominant communications paradigm, in which packets (units of information carriage) are individually routed between nodes over data links which might be shared by many other nodes. This contrasts with the other principal paradigm, circuit switching, which sets up a dedicated connection between the two nodes for their exclusive use for the duration of the communication. Packet switching is used to optimize the use of the bandwidth available in a network, to minimize the transmission latency (i.e. the time it takes for data to pass across the network), and to increase robustness of communication.

In packet switched networks (e.g., Internet), the data is split up into packets, each labeled with the complete destination address and routed individually. Circuit switched networks, such as the Public Switched Telephone Network (PSTN), also perform routing to find paths for circuits over which large amounts of data can be sent without continually repeating the complete destination address.

Power line communication (PLC), also called Mains Communication or Power Line Telecoms (PLT) or Powerband, is a term describing several different systems for using power distribution wires for simultaneous distribution of data.The carrier can communicate voice and data by superimposing an analog signal over the standard 50 or 60 Hz alternating current (AC). It includes Broadband over Power Lines (BPL) with data rates sometimes above 1 Mbit/s and Narrowband over Power Lines with much lower data rates. Traditionally electrical utilities used low-speed power-line carrier circuits for control of substations, voice communication, and protection of high-voltage transmission lines. High-speed data transmission has been developed using the lower voltage transmission lines used for power distribution. A short-range form of power-line carrier is used for home automation and intercoms.

A digital piano is a modern electronic musical instrument designed to serve primarily as an alternative to a traditional piano, both in the way it feels to play and in the sound produced. Some digital pianos are also designed to look like an acoustic piano.
Most digital pianos implement a variety of features not found on a real piano.

Digital pianos are implemented for MIDI, so they can control or be controlled by other electronic instruments and sequencers. They may also have a disk drive or other external media slot to load MIDI data, which the piano can play automatically. In this way, a digital piano can function as a player piano.

Health insurance, which is coverage for individuals to protect them against medical costs, is a highly charged and political issue in the United States, which does not have socialized health coverage. In theory, the market for health insurance provision should function in a manner similar to other insurance coverages, but the skyrocketing cost of health coverage has disrupted markets around the globe, but perhaps most glaringly in the US. Please see health insurance for a discussion of this category.

Dental insurance, like health insurance, is coverage for individuals to protect them against dental costs. Dental insurance usually goes hand-in-hand with health insurance, with most people in the United States receiving it included in their health insurance plan from their employer. Along with receiving dental insurance from your employer, there are ways to receive dental insurance through resellers and companies for individuals and families; although this way tends to be too expensive for most people.

Content management or CM is a set of processes and technologies that support the evolutionary life cycle of digital information. This digital information is often referred to as content or, to be precise, digital content. Digital content may take the form of text, such as documents, multimedia files, such as audio or video files, or any other file type
which follows a content lifecycle which requires management.

The digital content life cycle consists of six primary phases: create, update, publish, translate, archive and retire. For example, an instance of digital content is created by one or more authors. Over time that content may be edited. One or more individuals may provide some editorial oversight thereby approving the content for publication.

Publishing may take many forms. Publishing may be the act of pushing content out to others, or simply granting digital access rights to certain content to a particular person or group of persons. Later that content may be superseded by another form of content and
thus retired or removed from use.
