Networking devices are components that connect electronic devices and allow them to share resources over a network. Common networking devices include network interface cards, hubs, switches, bridges, routers, and modems. A switch connects network segments and can perform error checking before forwarding data packets between devices on a local area network. A router connects two or more networks and reads address information in packets to determine the best path to forward packets between networks. Routers work at the network layer and contain routing tables to define the addresses of connected networks.

Computer Network
A computer network is a digital telecommunication
network which allow nodes to share resources.
“Two or more computers connected together”

4. What are Networking Devices?
 Networking devices are component used to connect
computers or other electronic devices together so that they
can share files or resources like printers or fax machine.
Devices used to setup a Local Area network (LAN) are the
most common type of network devices used by the public. A
LAN requires a hub, switch, router, etc.
 Network devices are also called Communicating devices.

 NIC (Network Interface Card)
 HUB
 Switch
 Bridge
 Router
 Modem

6. A nodes is a basic devices or data point on a large network.
Devices Such as personal computer, cell phone, are node.
When defining nodes on the internet a node anything that
has an ip address.
Nodes

7. Switch
A network Switch is a computer networking devices that connects
network segments.
 Switches can perform error checking before forwarding data, which are
very efficient by not forwarding packets that error-end or forwarding
good packets.
 Switches can support both layer 2(based on MAC address) and layer
3(based on IP address) depending on the type of switch.
 Communicate in Full duplex mode.
Usually, large networks use switches instead of hub to connect
computers within the same subset.

9. Router
 A router is connected to two or more data lines from
different networks. When a data packet comes in one of
the lines, the router reads the address information in the
packet to determine its ultimate destination.
 A data packet is typically forwarded from one router to
another through the networks that constitute the
internetwork until it gets to its destination node.

10.  Best path selection.
 Work on third layer(network layer).
 It contain a routing table in which all information
about the address of connected networks.
Router

12. Advantages of router
 Router can function LAN & WAN.
 Router can connect different media.
 Router can define best path for data to reach
the destination.
 Router can filter the broadcasts.
