Short for Internet connection sharing, a method for connecting multiple computers in a LAN to the Internet through a single connection and a single IP address. ICS typically uses NAT technologies to achieve this and works with most connection technologies, including DSL, cable, ISDN, dial-up and satellite. The device with the modem or broadband interface that establishes the connection to the Internet is called the ICS host, or gateway while the other devices that connect to the Internet via the network and the ICS host are called ICS clients. If the ICS host fails, then all of the ICS clients lose their Internet connection.
Sharing an Internet connection can be achieved through either software or hardware solutions. All versions of Windows from Windows 98 and on have ICS software included in the operating system. However, there are also products such as WinGate and WinProxy, which are third-party shareware alternatives that will turn a computer into a gateway or proxy server. Hardware solutions involve a NAT-based hardware router that is connected directly to the Internet connection adapter, and each ICS client is then connected to the router.
Also referred to as simply Internet sharing, on Linux systems, this is called IP masquerading.
Acronym for Intelligent Character Recognition. ICR is the computer translation of hand printed and written characters. Data is entered from hand-printed forms through a scanner, and the image of the captured data is then analyzed and translated by sophisticated ICR software. ICR is similar to optical character recognition (OCR) but is a more difficult process […]
- Information and Communications Technology (ICT)

(1) See under IDE interface. (2) See under integrated development environment.
- IDE Interface
Abbreviation of either Intelligent Drive Electronics or Integrated Drive Electronics, depending on who you ask. An IDE interface is an interface for mass storage devices, in which the controller is integrated into the disk or CD-ROM drive. Although it really refers to a general technology, most people use the term to refer the ATA specification, […]
- Intermediate Distribution Frame (IDF)
Short for intermediate distribution frame, a cable rack that interconnects and manages the telecommunications wiring between an MDF and workstation devices. Cables entering a building run through a centralized MDF, then each individual IDF and then on to specific workstations. For example, an enterprise that encompasses a building with several floors may have one MDF […]
