Local area networks (LANs)
are used to connect networking devices that are in a very close geographic area, such as a floor of a building, a building itself, or a campus environment
Wide area networks (WANs)
are used to connect LANs together. Typically, WANs are used when the LANs that must be connected are separated by a large distance.
A MAN (Metropolitan Area Network)
is another category of network, though the term is not commonly used. A MAN is defined as a network that connects LAN’s across a city-wide geographic area.
An internetwork is a general term describing multiple networks connected together. The Internet is the largest and most well-known inter network.
Some networks are categorized by their function, as opposed to their size.
A SAN (Storage Area Network) provides systems with high-speed, lossless access to high-capacity storage devices.
A VPN (Virtual Private Network) allows for information to be securely sent across a public or unsecure network, such as the Internet. Common uses of a VPN are to connect branch offices or remote users to a main office.
Methods of Network Communication
Unicast : One to One Communication.used in both IPv4 and IPv6
Broadcast: One to all communication.Used in Ipv4 only
Multicast : One to a group communication.Used in both IPv4 and IPv6
Anycast : One to nearest Communication.Used in Ipv6
Broadcast Domain : A logical division of network where all devices can reach each othjer by broadcast
