Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access. Wide area network (WAN), a computer communications network that spans cities, countries, and the globe, generally using telephone lines and satellite links. Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. Broadband includes several high-speed transmission technologies such as: Digital Subscriber Line (DSL) Cable Modem Fiber Wireless Satellite Broadband over Powerlines (BPL) The broadband technology you choose will depend on a number of factors. One of America’s largest internet providers is uploading its oldest broadband technology into the sunset. Cable vs. DSL: The Speeds. It uses fiber-optic technology to reach the fastest speeds available today, as fast as 10000 Mbps (1Gpbs). Telecommuting may get even easier. WiMAX. Nomadic scenarios are very interesting from the user point of view. Historically, DSL speeds have been slower but new technology lessens the speed gap between DSL and Cable Internet. The Internet connects multiple WANs; as its name suggests, it is a network of networks. DSL: Stands for "Digital Subscriber Line." ADSL differs from the less common symmetric digital subscriber line (SDSL). Spyware on the computer: Even when the DSL network is functioning at full speed, spyware programs may consume bandwidth, robbing you of speed. In some cable modem networks, other computers on the cable modem network are left visibly vulnerable and are easily susceptible to break ins as well as data destruction. Fiber optic Internet is the future of broadband. The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Collectively, all types of DSL are referred to as xDSL. DSL is a communications medium used to transfer digital signals over standard telephone lines. This report was developed by the Technical Working Group for the Investigation of High Technology Crimes and is intended to be a resource for individuals responsible for investigations involving the Internet and other computer networks. Wireless Networking technologies connect multiple computers, systems and devices together without requiring wires or cables: a wireless local area network or WLAN comes under Wi-Fi. High bandwidth Cheap line charges from the phone company. The topic of “which is better and faster” has been a highly debated topic. mail, chat rooms, and file sharing networks can all yield evidence in an investigation of computer-related crime. Another possibility is to connect a wired technology, such as DSL, to the WiMAX link. In this case, the end users connect to the network infrastructure using DSL modems that are connected to the digital subscriber line access multiplexer (DSLAM) with copper lines. Broadband is essential to the modern world we live in. Powered by fiber optic technology, fiber Internet is blowing its competitors out of the water. DSL offers users a choice of speeds ranging from 128 Kbps to 3 Mbps. 2 I Advanced Network Technology Box l-A–Broadband Networks Computers and networks handle informa- Figure l-A-l—Digital Data tion as patterns of electronic or optical signals. There are wireless broadband systems that offer fast Web surfing without being getting connected through cable or DSL (Example of wireless broadband is WiMAX).
