Networking Devices:
Equipment which connects directly to a network segment is referred to as a Network device.
These devices are classified into two classifications.
End-User devices
Network devices
A repeater is a network device used to regenerate a signal. Repeaters regenerate analog or digital signals distorted by transmission loss due to attenuation. A repeater does not perform intelligent routing.
HUB:
Hubs concentrate connections. In other words, they take a group of hosts and allow the network to see them as a single unit.
Two Types of HUB:
Passive Hub : This is done passively, without any other effect on the data transmission.
Active Hub : Active hubs not only concentrate hosts, but they also regenerate signals
SWITCH:
A network switch is a computer networking device that links network segments or network devices / Nodes. Switches add more intelligence to data transfer management.
Switches can determine whether data should remain on a LAN or not, and they can transfer the data to the connection that needs that data.
The device which is used in a Single network to connect multiple systems.
Types of Switches:
Unmanaged Switch
Managed Switch
ROUTER:
A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks
Routers have all capabilities of the previous devices. Routers can regenerate signals, concentrate multiple connections, convert data transmission formats, and manage data transfers. They can also connect to a WAN, which allows them to connect LANs that are separated by great distances.
Device which is used between two or more different Network
Network Interface Card (LAN Card):
A network interface card (NIC) is a printed circuit board that provides network communication capabilities to and from a personal computer. Also called a LAN adapter.
