How Does The World Wide Web Work?

The first versions of WWW ((what most people call “The Web”))) provide means for people around the world to exchange information between, to work together, to communicate, and to share documentation more efficiently. Tim Berners-Lee wrote the first browser (called WWW browser) and Web server in March 1991, allowing hypertext documents to be stored, fetched, and viewed. The Web can be seen as a tremendous document store where these documents (web pages) can be fetched by typing their address into a web browser. To do that, two im- portant techniques have been developed. First, a language called Hypertext Markup Languag (HTML) tells the computers how to display documents which contain texts, photos, sounds, visuals (video), and animation, interactive

DNS is the service that translates from domain name to the matching IP address. The roles of the name servers in this process are:

Initially, HTML coding is what makes web browsing on any web browser possible. Basically what web-browsers do is that they read certain codes or code languages. HTML or "Hypertext Markup Language" is one of the coding languages that web browsers read. The web browsers read and translate these codes, displaying and producing what we see on our computer monitors or any internet capable device. Hypertext Markup Language was invented by a man by the name of Tim Berners-Lee, he made this so he could use his coding language and have it be displayed on the World Wide Web. These coding languages were made to be used on the World Wide Web to provide data and information to scientist all around the world as well as to let these scientist collaborate together to pull information together. Although the word-wide-web had already been invented Sir Tim had to find a way to connect this information all together. When Sir Tim sent in "Information Management: A Proposal" for the essentials of the world-wide-web to CERN in Mach of 1989 in which he described a

"URL is an acronym for Uniform Resource Locator, and is used to determine addresses on the World Wide Web. URL generally affirmed by sounding out every letter yet, in a few quarters, pronounced "Earl" - is an exclusive address for a file that is approachable on the Internet. An easy way out to get to a Web site is to enter the URL of its home page file in your Web browser 's address line. However, any file inside that Web site can likewise be indicated with a URL. Such a file may be any Web (HTML) page other than the home page, an image file, or a program such as a typical gateway interface application or Java applet. The URL includes the name of the protocol to be utilized to obtain the file resource, a domain name that recognizes a typical computer on the Internet, and a pathname, a hierarchical description that dictates the location of a file in that computer.

Scientists in the same year began to create what is known as today as the Modern World Wide Web, the emergence of the modern Internet today. Several online web servers held information on pages of text known as websites, in which they each had their own website name to access (History of the Internet). A new application called the web browser was created in order to access all of the web pages available on the internet to the public. The way the information was presented on the web page was with a hypertext markup language (HTML); this would become a standard format to display informational text (Goel, Tarun). A URL link was also introduced on the web browser as an address to access web pages for the public. The result of the internet had changed how people have done research to access more information and how people have communicated with one another (Goel, Tarun).

A web address that specifies the exact location of a web page. Uses letters and words that map to an IP address and a

The role of a web host is that they rent out space available on there servers by doing this this allows files to be connected to the internet they will only give you a set amount of space for a set fee this is used by thousands of people as it is not always possible to buy a server that can cost thousands of pounds

World Wide Web – Also known as WWW, which has a vast of data, websites, files and everything that would be connected to the internet. It is the structure for the servers that supports all kinds of formatted documents. The formatted documents are in HTML (Hypertext Mark-up language) which would be able to link in other documents such as graphics audio and video files. This is efficient as the user can go from document to another. Web browsers such as Google Chrome, Safari, and Internet Explorer allow World Wide Web to be operated so that the websites are easily accessible.

A URL (Universal Resource Locator) is defined, according to contests.about.com, as the “other name for a web address or the text that a web visitor types into their internet browser when visiting a website.” [1]. Contests.about.com, states further that once the web visitor provides the browser with a URL, it can find where to go in locating the web page that wants to be visited. The web page symbolizes the “resource” that the browser is trying to locate with a URL. Webopedia.com, defines a URL as the “global address of available documents and other resources on the world wide web.” [2]. Webopedia.com elaborates further that the first part of a URL is known as a protocol identifier and it indicates what protocol to use, and the second part is the resource name and it specifies the IP address or the domain name where the resource is located. A URL is the address of a webpage or file on the internet. For example, the URL of amazon website is “http://amazon.com”. The address of Amazon’s coupon page is

The World Wide Web uses 3 protocols HTML (hypertext markup language), HTTP (hypertext transfer protocol) and URLS (uniform resource locator). HTML is the coding language of the World Wide Web and gives the ability to

URL is an acronym for Uniform Resource Locator. It is the global address of resources and files on the World Wide Web. Just like a postal address enables mails to reach its destination, a URL allows the web browser to find a specific web page or file across the internet. For example, the URL for SJU’s library homepage is http://www.sju.edu/campus-life/library . A URL should be unique. It is a vital network identification for any resources like hypertext pages, images or sound files, connected to the web. It can make or break the website.

Domain structure allows programs to access different information. It is a group of computers that ensures the security and management of local accounts, for example the first domain controller. For example take the address https://www.youtube.com/channel/MadMoni. Https signifies hypertext transfer protocol, www refers to the World Wide Web and where the page is. Youtube.com is the domain name which links to a public IP address. Channel is a folder

The World Wide Web is established on numerous different technologies that make it possible for users to find and share data through the internet. For example there are Web browsers, HTTP (hypertext transfer protocol) and HTML (hypertext Markup language).

So how does one use or "navigate" on the Web? To understand that, one must first understand the language (that which makes it run, understand and execute commands) the web is based upon. This language is known as Hypertext Markup Language, which will later be discussed in more detail. Essentially, it the hypertext language uses "hot words to link pages to each other" (Halonen). The hot words, which have been termed links, consist of an underlying code, HTML, which is read and takes the user to the desired destination.

The Domain Name System is most often described as the Internet’s phone book or address book. All of us Internet users use it on daily basis without even realizing it. Its basic task is to convert human-readable website name like coursera.org into its computer-readable numerical IP address like 107.21.240.231.Since such strings of numbers are difficult for humans to memorize, DNS allows you to assign a domain name, such as facebook.com to you IP address. So, the domain name is simply an address on the Internet. It has to be unique just like physical address or phone number.
