There are different types of electronic devices used in networking for communication between different hardware used in the computer network. In a computer network, network devices are mainly used for transmitting and receiving the data quickly and securely in between computers, fax machines, printers, etc. These devices may be intra network or internetwork. In a computer network, each network device plays a key role based on their functionality, and also works for different purposes at different segments.

An enterprise network is an enterprise's communication backbone that helps connect computers and related devices across departments and workgroup networks, facilitating insight and data accessibility. It reduces communication protocols, promotes system and device interoperability, and improves internal and external enterprise data management.

Enterprise networking is traditionally centered on LAN standards with hardware switches, router devices, ethernet cabling, WIFI connections, and integrated firewall software all commonly used to create a Local Area Network. Enterprise WiFi enables users to access WiFi connections on a business property using mobile devices, laptops and other technology.

WiFi enables devices to connect directly to each other or to broad networks to deliver information. It is a key technology driving the IoT concept, and mainly operates in the frequency band of around 2.4 GHz and 5.0 GHz. WiFi is expected to be the leading segment, by connectivity, in the network devices market. From WiFi 5 to new WiFi 6 and 6E routers, gateways, and access points, WiFi connectivity provides the ideal performance, range and overall value.

A WiFi router connects directly to a modem through a cable. This allows it to receive information from and transmit information to the Internet. The router then creates and communicates with the home WiFi network using built in antennas, thus allowing all the devices on the home network.
