Intermediary devices-
switches
Network switches or packet switches are devices that connect the various segments of a network, and their main function is switching packets of data. Also known as a network bridge, they switch processes and rout data at the level of the data link layer, which is second of the OSI model layers (concerned with physical addressing of data). A switch may also operate at the level of other OSI layers like the physical, network or transport layer. Multilayer switches act at different OSI layers simultaneously. Network switches play a vital role in the functioning of local area networks.
Routers
As its name suggests, a router is an intermediary device that regulates and routs data traffic between computer networks. It forwards data to various network destinations and controls flow of data between two or more logical subnets, which do not have the same network address in a large network. It selects the optimum path for data transfer between two points in a network. Routers are one of the most vital network devices that make data transmission possible.
Modem
A modem (modulator - demodulator) is an intermediary device that converts analog signals transferred over networks into digital signals and digital signals back to analog. They enable the transmission of digital data over analog mediums like telephone lines and optic fiber cables.
Wireless Access Points
A wireless access point (WAP) is an intermediary device in a network that connects various types of wireless communication devices to connect with wireless networks. The connectivity is made possible through 'Bluetooth' and 'Wi-Fi technologies'. It acts as an intermediary between wireless devices and wired devices that are part of a network.
Hub
Working at the physical layer of the OSI model, a hub is basically a connector between ethernet segments which also control the bandwidth sharing among connected computer terminals.
Repeater
Repeaters are network devices that carry out the task of maintaining signal strength over its transmission through a network. They regenerate data signals and amplify them for further transmission.
Firewall
A firewall is any hardware appliance or software designed to filter network traffic that passes through it according to certain criteria and trust levels set by the network administrator.

What are types of network devices?
1. Lan Cards 2. Lan cables 3. Repeaters 4. Hub 5. Switches.
Why can you only populate 3 segments of a 5 4 3 network?
The other two segments must be link segments - connecting through network connectivity devices. Adding any clients on those two links would cause additional attenuation, which is not good for the network.
What are combination input and output devices?
Devices for communication between computers, such as modems and network cards , typically serve for both input and output. Also, a touch screen can be considered as an input and output. 1.Modems 2.Network Cards. 3.Touch Screen. 4.Headsets. 5.Facsimile (Fax). 6.Audio Cards/Sound Card.
What makes a network?
First of all you known about Networking when you make the network in LAN,MAN,WAN and any type of topology. 1- Topologies 2-LAN 3-MAN 4-WAN and the CISCO NETWORKING devices like cables, switches, Routers and entire building computers where you want to make Network.
Name 4 input devices?
what is name for input devices?
What are elements for data communication on a network?
Networks are comprised of software, hardware, a connection source and client devices. Software issues the commands needed to run the network. The hardware includes network cards, routers and switches. Connection sources are what the client uses to hook up with the internet. Networks won't operate without them. Client devices are the equipment a client will use to connect to the network.
The 5-4-3 rule?
The 5-4-3 rule is primarily for low speed coaxial networks. It states the maximums for a series of clients on the LAN. 5 total segments 4 connectivity devices 3 of the segments must be unpopulated (no clients on the wire) This works for a 10base network; when the speed goes up the number of devices, etc., become less. Staying within these maximums will allow the clients to contact each other. Exceeding the maximums may cause problems with connections within the network.
What is the 5 4 3 rule in networking?
On a standard Ethernet network, between any two devices that communicate (such as computers), you can't have more than 4 repeaters (this includes hubs). "5-4-3" refers to a maximum of 5 segments; 4 repeaters; 3 segments with hosts on them.
What is examples of communication technologys?
There are many examples of communication technologies. Some of the devices that help us all talk to each other are listed here: 1. Phones 2. Mobile phones 3. TV 4. internet 5. Radio
