Computer Networking

For small scale devices that could be used as a data communication medium is a computer network (Local Area Network), which can be developed using the technology becomes even larger international network (Internet) and this era of growing data communications with a variety of applications such as image 1.
The characteristics of computer networks:
1. share hardware (hardware).
2. Sharing software (software).
3. Sharing of communication channels (internet).
4. Sharing of data with ease.
5. Facilitate communication between network users.

While for the main application which runs on computer networks in general are:
• E-mail
• Discussions / electronic conference
• Shipping files / file electronically
• Access to the distributed database.
• Facilities telnet to work on a remote computer.
• And many more in accordance with its development.
Networking Type:
1. LAN (Local Area Network)
2. MAN (Metropolitan Area Network)
3. WAN (Wide Area Network)
4. Internet

Hardware required in general:
Hardware needed to build a computer network that is: either as a server computer or client, Network Card, Hub, and everything associated with network connections such as printers, CD-ROMs, scanners, Bridges, Routers and other needed to process the data transformation in the network.

Basic Computer Network Configuration:
Each computer in a network such as the environment for small-scale housing has often called the computer address or IP Address, using the TCP / IP protocol for addressing the type of computer.
Here are some utilities basic computer network configuration commands are:
1. PING
To check whether a computer is properly connected to the network.
2. Ipconfig
In general, to view the network configuration on a computer, for example determine the host, ip address, subnet mask, and others.
3. Tracert
Search about the routing of a network of networks.
4. Net stat
To find out the status of the network.
5. Nslookup
To know the IP address of a domain name or address of the site.
