Promiscuous mode is often used to diagnose network connectivity issues. There are programs that make use of this feature to show the user all the data being transferred over the network. Some protocols like FTP and Telnet transfer data and passwords in clear text, without encryption, and network scanners can see this data.
A network interface controller ( NIC, also known as a network interface card, [ 3] network adapter, LAN adapter and physical network interface[ 4]) is a computer hardware component that connects a computer to a computer network. [ 5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
Category:Graph theory. v. t. e. A network on a chip or network-on-chip ( NoC / ˌɛnˌoʊˈsiː / en-oh-SEE or / nɒk / knock) [ nb 1] is a network -based communications subsystem on an integrated circuit ("microchip"), most typically between modules in a system on a chip ( SoC ). The modules on the IC are typically semiconductor IP cores ...
Input/output. v. t. e. In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [ 1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware ...
For example, the 1961 Semiconductor Network Computer (Molecular Electronic Computer, Mol-E-Com), [7] [8] [9] the first monolithic integrated circuit [10] [11] [12] general purpose computer (built for demonstration purposes, programmed to simulate a desk calculator) was built by Texas Instruments for the US Air Force.
A personal area network (PAN) is a computer network used for communication among computers and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and video game consoles.
A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge[ 1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data ...
SCADA ( supervisory control and data acquisition) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes. It also covers sensors and other devices, such as programmable logic controllers, which interface with process plant or machinery.
