LAN :
The typical definition of Local Area Network (LAN) is "two or more connected stations (PCs, servers, computer…) in the same limited area, sharing data and peripheral devices, and operating .The most popular LANs include 10 Mbps & 100 Mbps Ethernet, 4 Mbps & 16 Mbps Token Ring.
HARDWARE COMPONENTS OF LAN NETWORK
The hardware components of a LAN consist of:
* PCs/workstations and servers
* Network Interface Card (NIC)
* Cabling and connectors,
* Hub, concentrator, and more complicated network devices such as Bridge, LAN Switch and Router
SOFTWARE COMPONENTS OF LAN NETWORK
The software components of a LAN can be grouped into two categories:
Inside PCs/workstations and servers
Inside network devices (Hub/Bridge/LAN Switch/Router)
HUB
A Hub is a central device used on star network topology that repeats or amplifies signals, allowing the network to be lengthened or expanded with additional stations. For example, an Ethernet hub normally has 8 or 12 or 16 RJ-45 ports, each port can be connected to a PC or workstation or server. Also, the hub’s BNC port can be connected to a coaxial cable to lengthen the network.
BRIDGE
A Bridge is a device used to connect two or more LANs. It operates at the Media Access Control Layer (layer 2), checking and forwarding data packets between different LANs.
LAN SWITCH
A LAN Switch is a device using switching hardware to speed-up the checking and forwarding of data packets between LANs. LAN Switch is functionally like a bridge, but its speed and performance is faster and better than a bridge.
ROUTER
A Router is a device that operates at the network layer (layer 3), routing data between similar or dissimilar networks. A router is more powerful than a bridge or LAN
