Introduction of Networks
A network is a combination of computers, servers, mainframes, network devices, peripherals,
or other devices associated to one another to confess the distribution of data. An great example
of a network is the Internet, which associate millions of people all over the world.

Types of Networks :
One style to classify the various types of computer network designs is by their scope or
scale. For historical reasons, the networking industry assign to closely each kind of design
as some type of area network. General kinds of area networks are :
scale. For historical reasons, the networking industry assign to closely each kind of design
as some type of area network. General kinds of area networks are :
- LAN - Local Area Network
- WAN - Wide Area Network
- WLAN - Wireless Local Area Network
- MAN - Metropolitan Area Network
- SAN - Small Area Network
- CAN - Campus Area Network
- PAN - Personal Area Network
LAN and WAN are the two popular and best known kind of area networks, while the others
have appear with technology suggestion

Note that network category vary from network topologies .
LAN : Local Area Network
A LAN associate network devices over a approximately brief distance. A networked office
architecture , school, or home general consist of a single LAN, though sometimes one building
will contain a few small LANs, and hardly a LAN will span a group of nearby construct . In
TCP/IP networking, a LAN is often but not always perform as a single IP subnet.

In addition to operating in a defined space, LANs are also commonly owned, contained , and
handled by a single person or organization. They also contribute to use certain association
technologies, mainly Ethernet and Token Ring.

WAN: Wide Area Network
As the term signify , a WAN spans a considerable physical distance. The Internet is the largest
WAN, spanning the Earth .
WAN, spanning the Earth .
A WAN is a geographically separate combination of LANs . In IP networking, the router handle
both a LAN address and a WAN address.
both a LAN address and a WAN address.
A WAN vary from a LAN in various essential styles . Most WANs are not purchased by any one
organization but rather access under selected or shareholding and management. WANs give to
utilize technology like ATM, Frame Relay and X.25 for association over the expanded scope .

LAN, WAN, and Home Networking
Address commonly apply one LAN and associate to the Internet WAN via an Internet Service
worker using a broadband modem. The ISP offer a WAN IP address to the modem, and all of the
computers on the home network use LAN IP addresses . All computers on the home LAN can
associate precisely with every another but must go through a basic network gateway, commonly a
broadband router, to ability the ISP.

Other Types of Area Networks
While LAN and WAN are by far the most leading network kinds specified , you may also generally
see associating to these others :
see associating to these others :
- Wireless Local Area Network - A LAN based on Wi-Fi wireless network technology
- Metropolitan Area Network - A network connect a physical area bigger than a LAN but lesser
than a WAN, such as a city. A MAN is generally purchased and operated by a single entity
such as a government body or bigger association . - Campus Area Network - A network connect various LANs but lesser than a MAN, such as on a
university or local business ground . - Storage Area Network - associate servers to data storage devices through a technology like Fibre
medium . - System Area Network (also known as Cluster Area Network) - Links high-performance computers
with high-speed connections in a cluster configuration .
