What is the Internet?
The Internet is a global network, which links computers all over the world via phone lines. Internet services provide users with easy access to the Internet. People from all walks of life use the Internet either for fun or for business purposes. Some of the activities that can be carried out on the Internet include web browsing, emailing, chatting, instant messaging, and using specialized software to play games. A variety of other activities, including social networking and file sharing also take place on the Internet.
The Internet works on a layer called the internet protocol, which carries digital packets of information from a local computer to a remote one. An IP packet has the data that is encapsulated in a binary format. IP packets make up a segment of the larger packet known as the IP header. This IP header can be identified by the unique IP address. This is necessary for all computers that connect to the Internet or for any network of computers that wish to access the Internet. All networks have addresses that are in a form that is easily remembered by users and are used in order to access certain resources on the Internet.
The Internet uses many different types of methods to transmit its packets of information. One popular method is the TCP/IP, which is an application layer protocol that enables several computers on the same network to establish connections to each other. This allows many different computers on the network to become familiar with each other’s protocols and enables the connection to be established. A good example of a TCP/IP server is the router that exists at every establishment that connects to the Internet. The Internet also makes use of so-called gateway servers, which allow data packets to be transmitted through a series of different servers so that it can reach its destination.
