HTML stands for HyperText Markup Language. HTML is the main language in which documents on the Web are displayed. HTML uses codes to specify how the content should appear to the user viewing it. These codes are entered on the page that is going to be displayed, however, once the codes have been properly written, they will not appear on the page. Instead, only the desired content will be seen. These HTML codes consist of tags inside angle brackets. An example would be “<title>”. Most HTML tags come in pairs. An example would be <body> and </body>. The first tag is known as the start or opening tag. The second tag is known as the end or closing tag. Notice how the second one was a “/”, that means it is the end of a specific content. Without the “/”, the content will not display properly. Then, within these tags is where web designers can add the desired text, comments, tags, and other types of text-based content that they may desire. Between the tags <html> and </html> is where the web page is described, and between <body> and </body> is the text visible on the page. There is however some tags which are unpaired. They are called empty tags. An example of an empty tag would be <img>. The name used in the tags, is the name of an HTML element, and they may not always contain content. With empty tags, the slash character, “/”, is not required or allowed. The default values are used if attributes are not mentioned.

URL stands for Uniform resource locator, which is what each web address is called. For example, http://www.google.com is the URL for Google. The URL could also contain additional information about the address, document, or folder where it is located. For example, http://www.google.com/news, also contains the word “news” which describes a specific section, and it means it will take you directly to the news section. On Wikipedia it states that, “A URL is technically a type of uniform resource identifier (URI) but in many technical documents and verbal discussions URL is often used as a synonym for URI.” According to the Internet Engineering Task Force(IETF), the Uniform Resource locator was created in 1994 by Tim Berners-Lee and the URI working group of the IETF. According to the World Wide Web Consortium, it was an outcome of collaboration started at the IETF living documents “birds of a Feather” session in 1992.
Here is an example of a typical URL:
A web browser is a software application primarily
used for accessing information on the World Wide Web. It retrieves, presents,
and transverses information resources found on the World Wide Web. A web
browser can also be used to access information on web servers that are in
private networks or files in file systems.
According to the World Wide Web Consortium, Tim Berners-Lee invented the first web browser in 1990. At the time is was called WorldWideWed, just like that with no spaces. I was later renamed to Nexus. Then, according to bloomberg.com Marc Andreesen made the browser even better by innovating the browser software with the release of Mosaic, which was later known as Netscape. It became the world’s first popular browser because it made the World Wide Web system easy to use to the average person. Many consider Andressen’s Browser the spark of the internet boom in the 1990’s. In 1995, Microsoft came out with internet Explorer, and according to search engine journal, internet explorer was being used by 95% of the people by 2002. The latest one came out in September on 2008, called Google Chrome. . According to search engine journal Even since its release its been increasing in usage every month, in august of 2011 it was being used by about 15% of users.
IP Address stands for Internet Protocol address. It is a series of dotted decimals to identify a device in a computer network that uses the internet protocol for communication. An IP address can serve one of two main functions. It can host or network interface identification and location addressing. According to the Internet Engineering Task Force (IETF), The designers of the Internet Protocol address defined an IP address as a 32-bit number, which is known as Internet Protocol Version 4 (IPv4), and it is still used today. Due to the huge growth of the Internet, a new addressing system was developed in 1995, called Internet Protocol version 6 (IPv6). IPv6 uses 128 bits for the address. The IP addresses are binary numbers, but they are normally stored in text files and displayed in a readable notation. For the IPv4 it would look something like this: 172.17.253.2. For the IPv6, it would look something like th1s: 2001:db8:0:1234:0:567:8:1
