As most of us know about the high popularity of internet services, many of the people just use the internet smoothly but they are not aware of actually what goes on behind the scene. Here I won’t drag you in typical description that how the Internet is the network of many big networks and so on, but while studying the functioning of the internet, websites and web hosting server, we would come to know that they are expected to fulfill the requests of client computers for specific webpages. Such clients use applications called browsers (Firefox, IE, Chrome etc.) while performing such requests for their desired webpages. Normally a URL (Uniform Resource Locator) is typed by client in to the address bar of the particular browser used by him, to direct to a web server by means of its Fully Qualified Domain Name (FQDN). For example to visit Host.co.in’s home page a visitor is required to only type http://www.host.co.in (FQDN) but if he want to visit contact us information of Host.co.in then he need to type FQDN (http://www.host.co.in) followed by path (/contactus.php)
‘http’(Hyper Text Transfer Protocol) is the most commonly used protocol for transferring webpages. There are also other two other types of protocols supported as ‘https’(Hyper Text Transfer Protocol over Secure Sockets Layer) and ‘FTP’ (File Transfer Protocol) specially used for uploading and downloading files.
