Describe the difference between the internet and the Web.

-The internet is a public, globally connected network of computer networks. -The web is a graphical user interface to information stored on computers running web servers connected to the internet. The web is a subset of the internet.

T/F The World Wide Web was developed to allow the companies to conduct e-commerce over the internet.

F, Before the World Wide Web the Internet really only provided screens full of text ... Berners Lee developed www to meet the demand for automatic information-sharing between scientists in universities and institutes around the world. WWW is a global collection of documents and other resources, linked by hyperlinks and URIs.

...is the set of markup symbols or codes placed in a file intended for display on a web browser.

HTML(hypertext markup language)

Explain the similarities and differences between a URL and a domain name.

A URL (Uniform Resource Locator) represents the address of a resource that is available on the internet. A URL consists of a protocol, a domain name, and the hierarchical location of the file or resource. An ex. is http://www.webdevfoundations.net/8e/chapter1.html. A domain name locates an organization or other entity on the internet and is associated with a unique numeric IP address. A domain name is part of the URL- it is- webdevfoundations.net

Describe the components of the client/server model as applied to the internet.

An example of a web client is a computer running a browser software application such as Internet Explorer. Typically the computer is connected to the internet only when needed. The web browser software uses HTTP to request web pages and related resources from a web server. A web server is a computer that is continually connected to the internet and that runs some type of web server software application. It uses the HTTP protocol to receive requests for web pages and related resources. It responds to those requests and sends the resources.

T/F A domain name that ends in .net indicates that the website is for a networking company.

F, it could be, but not necessarily; The domain name net is a generic top-level domain (gTLD) used in the Domain Name System of the Internet. The name is derived from the word network, indicating it was originally intended for organizations involved in networking technologies, such as Internet service providers and other infrastructure companies. However, restrictions were never enforced and the domain is now a general purpose namespace. It is still popular with network operators and the advertising sector,[citation needed] and it is often treated as an alternative to com.

Identify two protocols used on the internet to convey information that use the internet, but do not use the web.

In this chapter, several protocols are discussed that use the internet but not the web. E-mail messages are transmitted via the internet. SMTP(Simple Mail Transfer Protocol) is used to send email messages. POP(Post Office Tool) and IMAP(Internet Message Access Protocol) can be used to receive email messages. FTP (File Transfer Protocol) can be used in exchange (send and receive) files with a computer connected to the internet.

Of the following organizations, which one coordinates applications for new TLDs?

Internet Corporation for Assigned Numbers and Names (ICANN)

A standard language used for specifying a markup language or tag set is...?

SGML (Standard Generalized Markup Language)

T/F Markup Languages contain sets of directions that tell the browser software how to display and manage a web document.

T

T/F A URL is one type of URI.

T, A URI can be further classified as a locator, a name, or both. The term "Uniform Resource Locator" (URL) refers to the subset of URIs that, in addition to identifying a resource, provide a means of locating the resource by describing its primary access mechanism

The purpose of...is to ensure the integrity of network communication.

TCP(Transmission control protocol)

Explain three events that contributed to the commercialization and the exponential growth of the internet.

The commercialization and exponential growth of the internet that began in the early 1990s was due largely to a convergence of technologies, including the development of personal computers with graphical operating systems, widespread availability of internet connection services, the removal of the restriction of commercial use on NSFnet, the development of the World Wide Web by Tim Berners-Lee at CERN, and the development of a graphical browser called Mosaic at the NCSA. These events combined to to provide the commercial incentive and an easy way to share and access information in a manner that had never been experienced.

Is the concept of universal design important to web developers? Explain your answer.

Universal design is a very important concept for web developers because the websites that they create should be usable by all people. Not only is this the right thing to do, but in developing websites for the government or for educational institutions, access to technology (including websites) is mandated by law.

Which organization takes a proactive role in developing recommendations and prototype technologies related to the Web?

World Wide Web Consortium (W3C)
