What is World Wide Web (WWW)?
World Wide Web is a collection of interconnected computers offering or using services. The ones that offer services are called servers and others are internet users. Computers are connected via satellite links, telephone lines, fibre optic lines and Wireless data networks. These networks can carry data from point A to point B, point C and so on.
A website is collection of 2 or more pages interconnected through hyper links and hosted on a server or multiple servers publically available on the internet. There can be public or private websites based on the access parameters but we will limit our discussion to public websites. There are millions of websites on the internet today each offering a variety of services to web surfers around the globe.
The types of services that are offered on the internet are now countless. You can have voice, data, video streaming, audio streaming, RSS, Live feeds, financial transactions and more from these web pages. All the services are provided through servers. A Server is essentially a piece of software installed on a computer offering different services to the people who request it. These services are offered through different set of principles and procedures known as protocols. Protocols are necessary since every type of service is essentially data. The type of service uses different protocols to present information in a specific way.
When you type a website address also known as Uniform Resource Locator (URL) in a browser’s address bar, it searches for the location of web pages through an entry in the DNS (Domain Name Service). DNS is a directory service connecting these addresses to the web pages. Another advantage of the DNS is the use of friendly names instead of hard to remember hosting addresses. These names are more meaningful and easy to remember as well. You can book a domain name from a reseller like GoDaddy.com etc or Name.com.
Once you have purchased hosting and associated with a domain name, you can start designing and uploading your website and internet surfers will be able to find you easily on the internet.
