Purpose and Benefits of Computer Networking

A computer network is a set of computers that connect and communicate to achieve a particular goal. For example to share resources (printers and files) and surf. Computer networks support us to learn new things. For example by surfing, we can search for learning materials, news, weather information, streaming music and video and other information we want to find. It's as if the world is in our grip.

Data networks that once transported business information have shifted usability to improve people's lives everywhere. On the way, the resources available on the internet can help people to:

• Getting good weather information today or not.
• Find the fastest route to our destination.
• Check your bank balance and pay bills.
• Receive and send e-mail.
• Obtain health information from experts around the world.
• Getting cooking information and cooking techniques to create a spectacular dinner.
• Post photos or videos, communicate with friends around the world with chat apps and video calls.

Computer networks on the Internet use standard computer languages ​​(technically known as PROTOCOL) that allow different networks of computers and different computers to interconnect
communicate.

Computer network, certainly a lot of my friend who has often heard this term, especially children TKJ (computer and network engineering).

the computer network is a series or interconnected computer connections and also copy connected to each other that can interact and exchange data.

** Purpose of Computer Network **

Sharing resources, for example sharing printer usage, CPU, memory, hard drive.
Communication, for example e-mail, instant messaging, chat, video call.
Access information, for example web browsing.
Benefits of Computer Networking

History of Computer Networks

When seen from the beginning of the idea of ​​the use of computer networks. then approximately half a year more than 70 years old computer network technology is starting in use for the first time. if the current network
computer has been enjoyed by many people and also for various purposes,

There are several types of computer network protocols

• IPX / SPX (used by the Novell Netware network).

• NETBIOS / NETBEUI (used by Microsoft networks and
  Manager or Microsoft Windows Networking)

• AppleTalk (used for Apple Macintosh computers)

• TCP / IP (used by computer-based networks
  UNIX)

Benefits of computer networks are as follows

Resource sharing, can share and exchange data between computer network systems. Data exchange, graphics, video, voices, applications, printers, scanners, fax, modems and other hardware tools.
Saves money, can share an expensive resource usage.
High reliability, can have a supply of alternative sources.
Scalability, has the ability to improve system performance gradually in accordance with the workload.
Medium communication, capable of becoming a medium of inter-personal communication involved in a system that uses computer networks.
In order to achieve the same goal, every part of the computer network requests and provides services. The party requesting the service is called the client (client) and the one providing the service is called the maid (server). This architecture is called client-server system and is used in almost all computer network applications.

Initially, the idea to create a computer network is just for a computer system device to be connected to each other
and can be used together. This is of course influenced by the price factor of a computer that is still expensive, and can not be purchased by ordinary people at that time and also not much in use by many people.

Thus the discussion of the definition, purpose and benefits of computer networks. May be useful...
