IP ADDRESS ::

Home address & IP Address IP is an indication of a computer or device on a / TCP IP network. Networks using the TCP / IP protocol route messages based on destination IP address.

Format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

Within an isolated network, you may want IP addresses at random as long as each is unique. However, connecting a private network on the Internet requires using registered IP addresses (called Internet addresses) to avoid duplicates.

 The four numbers in an IP address is used in different ways a particular network and a host on the network to identify. Four regional Internet registries - ARIN, RIPE NCC, LACNIC and APNIC - Internet addresses indicated by the following three classes.

Class A - supports 16000000 hosts in each of 126 networks

Class B - supports 65,000 hosts on each of 16,000 networks

 Class C - supports 254 hosts on each of 2 million networks

The number of Internet addresses assigned is running out, so a scheme CIDR Classless new branding is gradually replacing the system based on classes A, B and C and is associated with the adoption of IPv6...

WHAT IS DIFFERENCE BETWEEN LAN AND WAN AND MAN ?

A LAN (local area network) is a group of computers and network devices connected together, usually in the same building.

A WAN (wide area network) is not restricted to a geographical place, even though it may be confined within the borders of a state or country.

A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or open to the public. Technology is a high speed and relatively expensive.

 The Internet is an example of a worldwide public WAN.

A LAN (local area network) is ' A group of computers and network devices are connected, usually in the same building. By definition, connections with high speed and relatively inexpensive (eg, draw ring or Ethernet), to be. Most of Indiana University in Bloomington department LAN.

A LAN is a high speed connection in a LAN. In IUB campus, compounds are either Ethernet (10Mbps) or Fast Ethernet (100Mbps), and some countries have Gigabit Ethernet (1000Mbps) connections ....

 LAN (Local Area Network) is a network which has a small geographic area, like a home, office, or group of buildings of the Network in an organization can have a LAN typically owned, controlled and managed by a single person or organization is typically owned, controlled and managed by a single person or organization have LAN high speed data transfer Got a small geographic range and have no need for a telecommunication lines LAN employee may be used for other LAN is connected over a distance via telephone lines and radio waves WAN

WAN (Wide Area Network) is a computer network covering a wide area (eg, a link communication network among the metropolitan boundaries, regional, or national Internet is the best example of a WAN WAN (eg Internet) is not owned by any organization, but rather exist under a collective or distributed ownership management and technologies tend to wane as ATM, Frame Relay and X.25 use to access over longer distances eating has a lower data transfer compared to LAN Have a great geographic diversity across borders general and rental of telecommunications lines must

WHAT IS WAN ( WIDE AREA NETWORK )::

Definition:

 A WAN covers a large geographical area, as a province, state or country. WAN networks often several smaller, such as local area networks (LAN) or metro area networks (MANS). Most popular WAN is the Internet worldwide. Some segments of the Internet, such as VPN-based networks, WAN is also in themselves. Finally, many WAN is corporate networks, or research using leased lines. WAN typically use different and more expensive than LAN Network. Key technologies often include WAN SONET, Frame Relay, and ATM.

DEFINATION OF LAN:

Definition:

A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other as in an office building, a school or a home. A LAN is useful for sharing resources such as files, printers, games or other applications. A LAN in turn often connects to other LANs and the Internet or other WAN.

LOCAL AREA NETWORK:: < LAN >

A computer network that includes a relatively small area. Most LANs are confined to a single building or group of buildings. However, it can have a LAN connected to other LANs over any distance via telephone lines and radio waves.

A system of LANs connected in this way a wide-area network (WAN). Most LANs connect workstations and personal computers. Each node (individual computer) in a LAN has its own CPU with which it executed programs, but it is also capable of data and devices anywhere access to the network. This means that many users of expensive devices like laser printers, and data exchange.

Users can use the LAN to communicate with each other, sending e-mail or engaging in chat sessions. There are many different types of LANs Ethernets being the most common for PCs. Most Apple Macintosh networks are based in the Apple Talk network of Macintosh computers built.

The following features distinguish a LAN from another: topology: geometric arrangement of devices on the network. For example, equipment can be arranged in a ring or a straight line. protocols: The rules and encoding specifications for sending data. Protocols also determine whether the network uses a peer-to-peer or client / server architecture. media devices can be connected by twisted-pair wire, coaxial cables, fiber optic cables either. Some networks do without connecting media altogether, communicating instead via radio waves.

 LANs are capable of transmitting data at very fast, much faster than data can be transmitted to a telephone line, but the distances are limited, and there is a limit to the number of computers which can be for a LAN single attached.
