Computer Networking Making Life Easier Network technologies can be classified as one of the two very fundamental groups. The LAN (local area network) technologies can be used to connect multiple devices that are kept relatively close to each other, say in the same building. For example the library terminals that show the information of books, are usually connected over LAN technology. Similarly, WAN or the wide area network is used to connect comparatively smaller number of devices that may be kept some kilometers away. For instance, if two libraries situated at the corners of the city want to share some common information then that would most likely be done using the wide area network technology. As compared to the WANs, the LANs are much faster and more consistent. However, continuous improvements in the technology persistently blur the line of demarcation. Today, the fiber optic cables have made it possible for the LAN technologies to connect the devices that are tens of kilometers apart; and, all this along with improving the reliability and speed of WANs. All this contribute to make the life of common man easier. Now, we can access the information that it is kept in some other corner of the building or the city, by just accessing the LAN or WAN connection. The Internet technology is in fact one of the greatest communications developments of the 20th century that has helped us in staying connected. It allows people staying in different corners of the globe to send e-mails to one another in the flip of the eyelid. The web pages, e-mail messages and the files download are all the boon of the entire computer networking on a higher level. This is the basis on which a person with his computer in Greece can connect and talk through his computer to another person sitting in the U.S. This is how, computer networking both at its basic level as well as hi-tech stage helps in making life easy for the common man.
