RQ2. Describe in two paragraphs the origins of HTML. Explain how markup tags work in HTML, and describe the role of at least one person involved with HTML’s development.

Hypertext was first introduced by Ted Nelson in the 1960's to describe a page-linking system. The concept of his system would allow one page to link text to other pages. In doing this, pages of information could connect from different storage locations. However, it was not until Tim Berners-Lee that Hypertext Markup Language (HTML) was actually developed.
Berners-Lee created a set of codes that could connect to the hypertext server, which stored written HTML files. These set of codes, also known as tags defined the relationship between text and elements, allowing the creation of web pages. For example, one set of tags can designate text for a header element while another can designate text for a footer element, thus, allowing the server to extract those text into the header and footer of the visible web page.

RQ3. In about 200 words, compare the POP e- mail protocol to the IMAP e- mail protocol. Describe situations in which you would prefer to use one protocol over the other and explain the reasons for your preference.

Both POP and IMAP e-mail protocols allow clients to send and receive e-mail as well as support Multipurpose Internet Mail Extensions (MIME), which are attachments such as documents, photos, and music. The Post Office Protocol (POP) runs on an email program, which connects to a server, while the Interactive Mail Access Protocol (IMAP) runs directly on the server.
With POP, the email program such as Outlook or Entourage acts as a post office where mail is delivered and sent out, while the server acts as the postman. However, without the postman (server), mail cannot be sent or received. Also, a client can only access and edit email by downloading it through the program as oppose to IMAP, which can be visible and worked on from any computer by accessing the online server.
For me, I prefer POP email when it comes to work because the only place I really need to view my email would be at work, therefore having it accessible to one computer is not an issue. Also, with the amount and importance of my correspondence, POP allows me to control storage space and location. However, I prefer IMAP email when it comes to school because it’s something I would want access to anywhere without having to download it to a program.

RQ4. In about 400 words, describe the similarities and differences between XML and HTML. Provide examples of at least two situations in which you would use XML and two situations in which you would use HTML.

Like HTML, Extensible Markup Language (XML) derived from the original Standard Generalized Markup (SGML). Both languages are currently managed by W3C and can be written in any general text editor or word processor. However, while HTML is a markup language with defined tags, XML is a framework with custom tags making it a meta language.
This custom markup was designed primarily for companies needing to share information online. With ecommerce growing among companies, data such as inventory and price lists needed more support than HTML. Issues with HTML unable to handle large amounts of data lead to the creation of XML. With XML, data lists are visibly more organized and data management capabilities can easily maintain product information.
XML uses a database format by pairing start and stop tags to record data, but unlike HTML, XML tags are visible when seen on a browser. However, while HTML files can directly display on a browser through a server, XML files must be converted by passing through another file, such as embedding it to an HTML file or other program in order to become visible.
Another big difference between XML and HTML is that while HTML defines the format and style of text, XML does not. Instead, XML provides the semantics or meaning of the text. An example of this is best shown when
