The Internet And How It Works

The Internet And How It Works

The internet is referred to as a “packet switched” network. This means that information sent over the internet is not done so via a direct, unbroken connection between sender and receiver. Instead the information is broken up into smaller “chunks” or packets, and then sent over many different routes where it is finally reassembled at the receiving end. This mechanism is handled by the two fundamental internet protocols; Transaction Control Protocol (TCP) and Internet Protocol (IP) and is collectively referred to as TCP/IP. The TCP’s task is to break down the information into packets and reassemble while the IP’s task is to ensure the packets are sent to the correct destination.
The internet can be viewed in many different ways. It functions as an information source due to the vast number of websites that currently exist and at the same time it functions as a collection of networked computers as it is an amalgam of thousands of individual telecommunication networks. It also functions as a collection of individuals and organizations, tool to link business to business and a tool to link business to consumer. E-commerce is a term that is being used hand-in-hand with the internet. Gone are the days when businessmen thought that website designing is a novel extension to their business. It has become a necessity and something very ordinary for every business.
Website designing and creating for commercial purposes has become merely a 4 step simple process. First step is registering a domain name; which is not just an address on the internet; it is also the e-business brand name. The next step is to find a third party, a “web host” to host the site. Next you need to join a payments system to provide the capability to make and receive payments and the final step is to obtain web software to enable creation of the site and ordering facilities. A few things to consider when creating e-business are to set goals and know what is to be achieved and who the audience is. Be realistic, be committed and responsive by making it look attractive and keeping it updated.
Another widely used term when talking about the internet is “search engines”. A search engine is a website that uses its own software, sometimes referred to as “intelligent robots”, “web spiders” or “web robots” that roam, catalogue, index and compile references to as many websites as they possibly can. They follow hyperlinks contained in each web page they encounter and continue this process from website to website, building up libraries of information as they progress. Visitors to this site can then interactively query information that is enlisted by the search engine.
