With a bridge you can connect different types of networks, e.g. a wireless network and an Ethernet network. A repeater expands the reach of your wireless network, which comes in handy if you have a bad or slow connection in some remote corners of your home or office.
DECT is the system for creating cordless telephones for home use. DECT base stations are the units which are connected to the phone line and the places where cordless handsets are rested when not in use, in order to recharge their batteries.
A gateway is a router or a proxy server that routes between networks. A controller is a chip, an expansion card, or a stand-alone device that interfaces with a peripheral device.
By placing a firewall between your local network (LAN/WLAN) and the Internet, you can make it very hard for hackers to gain access to your local network. That is, if you have configured your firewall correctly. This can be especially important for businesses and people with sensitive information on their computer systems. A very neat function most hardware firewalls have is the ability to securely connect the local area network to other local area networks in different locations over the Internet, thus creating a Virtual Private Network (VPN). With VPN you can safely share network resources with remote offices or play games with your friends as if you were on the same LAN!
Device which improves the quality of power that is delivered to electric load equipment.
Device which converts digital data from computers into electric signals which can be transmitted over a telephone line, and convert electric signals which it receives into digital data for computers.
These devices connect to the network to calculate key performance indicators to monitor the network and speed-up troubleshooting activities.
Device which creates a wireless network by sending out radio waves across a certain range.
Device that extends the range of a network or interconnects two different types of networks.
Devices which allow the management of a computer network.
Device which changes signals on a copper cable to signals that run on fiber, letting a company introduce fiber in the network without making other changes.
Device used to split a signal if the signal must be sent to two or more devices.
A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.
Device comprising both a transmitter and a receiver which are used in computer networks.
Network device used by telecom carriers to switch high-speed optical signals e.g.OC-3, OC-12, OC-48.
Number of circuits, usually of the same or similar type, which appear on jacks for monitoring, interconnecting, and testing circuits in a convenient, flexible manner.
A Power Over Ethernet (PoE) Adapter is a device that injects power into an Ethernet network or a device that connects a non-PoE device to a PoE network.
Power line communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. It is also known as power line carrier, power line digital subscriber line (PDSL), mains communication, power line telecommunications, or power line networking (PLN).
Connect one or more printers directly to your Local Area Network and share it/them with all the computers on your network, using one of these print servers.
An adapter is a physical device that allows one hardware or electronic interface to be adapted (accommodated without loss of function) to another hardware or electronic interface. A remote management adapter allows you to manage systems remotely.
Devices that allow you to speak on the phone hands-free by using a speaker and a microphone.
Cables used to transmit telephone signals.
Video telephone and other devices used for setting up and delivering video conferencing, which is where two or more separate locations communicate by simultaneous two-way video and audio transmissions.
With a router you can connect networks. Most people will use a router to connect their local (wireless) home or office network (LAN) with the Internet. The router makes sure that all computers on the local network can connect with one another, with shared resources and with the Internet and can be configured to forward requests for connections from computers on the internet to the appropriate local computer. In order to connect your local network to the internet via an ADSL or cable, you also need an (Ethernet) ADSL or cable modem if it is not built-in in the router, which is most likely to be the case.
With a WLAN (Wireless Local Area Network) access point you can build your own wireless network and share network resources like printers and storage space. You can even share one internet connection with your entire wireless local area network by connecting your access point (by Ethernet) to your (A)DSL or cable modem with built in router/DHCP server!
