All about data network
Posted by Johny Dean on May 2nd, 2013
A data network is a telecommunications network that requires specific software and hardware. This network interconnects computers or servers and allow them to exchange information. With the help of a network like this, users can send and receive electronic letters, spreadsheets, charts, graphics, and any other type of documents. Data networks can be private (this type of networks is used mainly within companies) or public (these networks are available for both individuals and companies that use the services of a certain carrier).
Data networks rely on the Ethernet to work, but also on the Wireless technology. The difference between Ethernet and Wireless is that with Wireless, you to not need data cabling to be able to send and receive electronic information with other people using the same network; you can enter the network wirelessly, meaning without connecting first to an electrical conductor, like it happens with the Ethernet. Although the Wireless technology seems more attractive, the Ethernet is very popular as well, and it continues to be improved day by day. At the beginning, data cabling used coaxial cable as a shared medium, and now it uses fibre optic links.
The benefits of a data network are obvious. With the power of data networking, people can share information, can get help from people located thousands of miles away from them, and can even access the resources found in someone else's computer. People who share the same network can communicate easier and much cheaper online than by phone. In fact, with the right software, they can enjoy the advantages of a telephone call when using their very own computers. Also, individuals and companies can access information stored on other computers that share the same network, if they are allowed to do so. Information security is highly important, especially to companies storing vital details on their work, therefore it is recommended to limit the access to information to a level considered safe.
Speaking of security, this has a significant meaning as a part of any data communication network. Although information can be encrypted and protected with passwords, network crackers can always find their way into data networks. To keep this from happening, carriers should focus on increasing the security level for a better protection against viruses, malware, computer worms and other software programs and applications that have stealing information and damaging the network as main goals. Among the best and most effective security solutions for computers sharing the same network, there are software firewalls, script blocking programs, and antivirus software. They recognize attacks and block them from damaging the operating system and applications stored on a computer.
