Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).

Network firewalls are systems that enforce access control policy between an organization's network and the Internet for security purposes.
|
|
Network gateways interconnect networks with different, incompatible communication protocols.
|
|
Network hubs serve as the central location for attaching wires to workstations.
|
|
Network modems (modulators-demodulators) are devices or programs that allow computers to transmit data over telephone lines. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information.
|
|
Network monitoring software is used to monitor network traffic for user-defined parameters.
|
|
Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.
|
|
Network security platforms are designed to protect networks from incursion by external sources.
|
|
Network servers control and manage network resources such as files, printers, users, groups, etc.
|
|
Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.
|
|
Network transceivers, short for transmitter-receiver, are devices that both transmit and receive analog or digital signals.
|
|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
