The father of the World Wide Web, Tim Berners-Lee, having recognized that the internet contains millions of items and each item needed to be uniquely identified, in1994, developed and implemented the idea for addressing each resource on the internet. He called these addresses as Uniform Resource Identifier which were later renamed as Uniform Resource Locator.
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.
The basic components of a URL makes it easier to identify from where the web page originates and who is responsible for the information on the page. Every URL has basic parts; the Protocol, the server name, the path, the query and the parameter. The protocol identifies the method through which the resource is transmitted on the internet. It is a set of rules a web server and a browser use to connect and comprehend each other. The most commonly used protocol is http which stands for Hypertext Transfer Protocol. The server name generally recognizes which organization, office or
Define URL and why you as an analyst should care about its importance. Explain the URL Parameters. Explain cookies and why these matter.
The first step is to identify whether the URL is of http or https. In the beginning, network administrators had to figure out how to share the information they put out on the Internet. It is agreed on a procedure for exchanging information and called it HyperText Transfer Protocol. Using HTTPS, the computers agree on a "code" between them, and then they scramble the messages using that "code" so that no one in between can read them. This keeps your information safe from hackers. It uses the "code" on a Secure Sockets Layer (SSL), sometimes called Transport Layer Security (TLS) to send the information back and forth.
Sir Tim Berners-Lee is an British physicist,who is also known for his invention that changed the history of computers and our life: The World Wide Web. Until 1990, people were using Internet only for e-mail because information on the Internet was spread and there was not a way to access it all.All that changed with the invention of the World Wide Web. The whole idea of World Wide Web was simple thought on Berners Lee’s mind that it would be great idea for researchers to be able find the documents they needed from any computer in the world.In 1980, he made his first attempt to create resource by writing a program called Enquire to organize documents, lists of people, and the projects on his computer.The hypertext program on his computer would
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.
They wanted to devise an inter-networking system (or internet) whereby different networks could ‘talk’ to one another. Arpanet devised TCP/IP (Transmission Control Protocol/Internet Protocol). This was a set of rules for communication between networks. The Internet became a network of networks. Only the military stayed outside of this for security reasons. In 1988, there were 50,000 computers attached to the Internet. By 1991, there were 1 million. However, it was difficult to access the information contained on the Internet as the system had little organisation. This problem was solved by Tim Berners-Lee, a British scientist studying at a research facility in Switzerland. He invented a method of organising information which he called the world-wide-web (www). His system linked documents from different sources and guided users to related information. The www was first used by the public in 1991 and it allowed the transfer of text, sound, images and video clips. Above all else, it was simple to use.
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).
HTTP - HyperText Transfer Protocol (HTTP) is the underlying protocol used by the World Wide.
Internet Is Born. The World Wide Web, Internet Protocol (HTTP) and WWW language (HTML) and are created by Tim Berners-Lee.
Tim Berners-Lee’s biggest accomplishment was creating the web. In 1989 he created the World Wide Web at the European Particle Physics Laboratory. It started as a distributed collaborative hyper-media information system. Tim designed it as a protocol for linking a multiplicity of documents located on computers anywhere within the internet. The protocol he created is known as HTTP(hypertext Transfer Protocol) which is the set
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
Lastly, the third rule is that when the information is received from the HTTP protocol all the data should be contained in data relationships. Stating that data is relationships, meaning that all the information given in one HTTP contains all the data and relationships in a single hyperlink making everything much simpler than before. Ultimately, everything that is mentioned in these three rules all comes down to being linked data. Linked data is all the relationships and information that is used in these HTTP protocols and returns the data for easier access by using these relationships, instead of using multiple programs in order to find information based on one piece of data. Berners-Lee goes on to finish his presentation by stating that this whole process of using HTTP protocols is simply the use of linked data and the many connections involved when using this data. In another presentation, Berners-Lee discusses the idea behind modifying and implementing a user interface on web pages and how the web went worldwide. When the web was being used more often, it went worldwide, which ultimately brought up the question of how all this complex data being used everywhere was going to be tracked. Berners-Lee states that satellites are used in order to make “mash-up” maps that hold data all around the world and use a user interface in order to properly organize traffic, energy, and other important data onto these so called mash-up maps.

Like a key to the door, by entering the URL of a website in the web browser’s address line, you can get to the page in that website. Any file within the website can also be specified with a URL, like any (HTML) web page.

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.
