Bandwidth managementBandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link, which would result in network congestion and poor performance of the network. Bandwidth is described by bit rate and measured in units of bits per second (bit/s) or bytes per second (B/s).
Traffic congestionTraffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the traffic stream, this results in congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads.
Internet of thingsThe Internet of things (IoT) describes devices with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks. The Internet of things encompasses electronics, communication and computer science engineering. Internet of things has been considered a misnomer because devices do not need to be connected to the public internet, they only need to be connected to a network, and be individually addressable.
Internet censorship in AustraliaInternet censorship in Australia is enforced by both the country's criminal law as well as voluntarily enacted by internet service providers. The Australian Communications and Media Authority (ACMA) has the power to enforce content restrictions on Internet content hosted within Australia, and maintain a blocklist of overseas websites which is then provided for use in filtering software. The restrictions focus primarily on child pornography, sexual violence, and other illegal activities, compiled as a result of a consumer complaints process.
Internet caféAn Internet café, also known as a cybercafé, is a café (or a convenience store or a fully dedicated Internet access business) that provides the use of computers with high bandwidth Internet access on the payment of a fee. Usage is generally charged by the minute or part of hour. An Internet cafe will generally also offer refreshments or other services such as phone repair. Internet cafes are often hosted within a shop or other establishment.
History of the InternetThe history of the Internet has its origin in information theory and the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
Internet censorship and surveillance by countryThis list of Internet censorship and surveillance by country provides information on the types and levels of Internet censorship and surveillance that is occurring in countries around the world. Detailed country by country information on Internet censorship and surveillance is provided in the Freedom on the Net reports from Freedom House, by the OpenNet Initiative, by Reporters Without Borders, and in the Country Reports on Human Rights Practices from the U.S. State Department Bureau of Democracy, Human Rights, and Labor.
TrafficTraffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections.
Honeypot (computing)In computer terminology, a honeypot is a computer security mechanism set to detect, deflect, or, in some manner, counteract attempts at unauthorized use of information systems. Generally, a honeypot consists of data (for example, in a network site) that appears to be a legitimate part of the site which contains information or resources of value to attackers. It is actually isolated, monitored, and capable of blocking or analyzing the attackers. This is similar to police sting operations, colloquially known as "baiting" a suspect.
Physical layerIn the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer: the layer most closely associated with the physical connection between devices. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to broadcast on, the line code to use and similar low-level parameters, are specified by the physical layer.
