Automatic test equipment or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results. An ATE can be a simple computer-controlled digital multimeter, or ...
The predecessors to firewalls for network security were routers used in the 1980s. Because they already segregated networks, routers could apply filtering to packets crossing them. [7] Before it was used in real-life computing, the term appeared in the 1983 computer-hacking movie WarGames, and possibly inspired its later use. [8]
Network naming can be hierarchical in nature, such as the Internet's Domain Name System. Indeed, the Internet employs several universally applicable naming methods: uniform resource name (URN), uniform resource locator (URL), and uniform resource identifier (URI).
The history of the Internet has its origin in 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 ...
In practice, a supplicant is a software application installed on an end-user's computer. The user invokes the supplicant and submits credentials to connect the computer to a secure network. If the authentication succeeds, the authenticator typically allows the computer to connect to the network. IEEE 802.1x network-diagram example.
TDLS, or Tunneled Direct Link Setup, is "a seamless way to stream media and other data faster between devices already on the same Wi-Fi network" based on IEEE 802.11z and added to Wi-Fi Alliance certification program in 2012. Devices using it communicate directly with one another, without involving the wireless network's router. [43]
A circuit between two points in different locations may be tested by applying a test signal on the circuit in one location, and having the network device at the other location send a signal back through the circuit. If this device receives its own signal back, this proves that the circuit is functioning.
Mobile devices are also effective conveyance systems for malware threats, breaches of information, and thefts. Wi-Fi interference technologies can also attack mobile devices through potentially insecure networks. By compromising the network, hackers are able to gain access to key data. Devices connected to public networks are at risk of attacks.
