Enumeration definition

Constant	Description
ANTENNA	A transducer designed to transmit or receive electromagnetic waves.
COMPUTER	A desktop, laptop, tablet, or other type of computer that can be moved from one place to another and connected to an electrical supply via a plugged outlet.
FAX	A machine that has the primary function of transmitting a facsimile copy of printed matter using a telephone line.
GATEWAY	A gateway connects multiple network segments with different protocols at all layers (layers 1-7) of the Open Systems Interconnection (OSI) model.
MODEM	A modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information.
NETWORKAPPLIANCE	A network appliance performs a dedicated function such as firewall protection, content filtering, load balancing, or equipment management.
NETWORKBRIDGE	A network bridge connects multiple network segments at the data link layer (layer 2) of the OSI model, and the term layer 2 switch is very often used interchangeably with bridge.
NETWORKHUB	A network hub connects multiple network segments at the physical layer (layer 1) of the OSI model.
PRINTER	A machine that has the primary function of printing text and/or graphics onto paper or other media.
REPEATER	A repeater is an electronic device that receives a signal and retransmits it at a higher level and/or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances without degradation.
ROUTER	A router is a networking device whose software and hardware are usually tailored to the tasks of routing and forwarding information. For example, on the Internet, information is directed to various paths by routers.
SCANNER	A machine that has the primary function of scanning the content of printed matter and converting it to digital format that can be stored in a computer.
