Science Study Guide Exam Questions
Well Answered.
Internet - Answer The Internet is a massive network of networks, a networking infrastructure. It
connects millions of computers together globally, forming a network in which any computer can
communicate with any other computer as long as they are both connected to the Internet. Information
that travels over the Internet does so via a variety of standards known as protocols.
World Wide Web - Answer A global system of hypertext documents, created using the Hypertext
Markup Language and accessed over the internet, containing internal links and/or links to other
documents
Difference between the internet and the World Wide Web - Answer Internet is the infrastructure which
enables computers, servers, and other devices to establish communication by means of cables and
satellite connection. Whereas, World Wide Web is the sue of the internet to access data and enable data
exchange between users all over the globe.
Evolving web - Answer The web was first a platform of data exchange with a limited number of users
with applications. Then commercials application were added to the web. With web 2.0, users demand
for social aspects has been added to help computers understand the meaning behind the webpages and
the interaction between the computer and the users. Due to the progress of technology and availability
of high speed internet, mobile devices and connected things such as fridges, houses, cars will play a
bigger role.
Hypertext Transfer Protocol (HTTP) - Answer (HTTP) A protocol that is a communications standard for
sending and receiving documents on the Web; it transfers files from a web server to a web browser and
interprets hyperlinks in order to navigate to a specific location. It describes the data exchange in the
World Wide Web, which port to use and how the data should be formatted.
Hypertext Transfer Protocol Secure (HTTPS) - Answer A layering of the Hypertext Transfer Protocol
(HTTP) on top of the SSL/TLS protocol, thus adding the security capabilities of SSL/TLS to standard HTTP
communications. (It is similar with HTTP but is extended with a security component that encrypts that
data exchange between sender and receiver)
, Hypertext Mark-Up Langauge (HTML) - Answer A language that is the standard markup language used
to create web pages. (standards for formatting content that is to be displayed in computer browsers)
Can be rendered 提供 by al internet browsers; use of tags to delimit 劃界 statements
Extensible Mark-Up Langauge (XML) - Answer A meta-language used to represent and manipulate data
elements. Unlike other mark-up languages, XML permits the manipulation of a document's data
elements. XML facilitates the exchange of structured documents such as orders and invoices over the
internet.
It does not contain a fixed set of tags, therefore, new ones can be added
Cascading Style Sheet (CSS) - Answer A style sheet language used for describing the look and
formatting of a document written in a markup language.
Extensible Style Sheet Langauge Transformations (XSLT) - Answer A language for transforming XML
documents into other XML documents, or other objects such as HTML for web pages, plain text or into
XSL Formatting Objects which can then be converted to PDF, PostScript and PNG.
Javascript - Answer A web-scripting code that interacts with HTML code to create dynamic content,
such as rollovers or interactive forms on a web page.
Uniform Resource Identifier (URI) - Answer A string of characters ned to identify a resource. Such
identification enables interaction with representations of the resource over a network, typically the
World Wide Web, suing specific protocols.
Uniform Resource Locator (URL) - Answer An address that can be used to locate a resource on the web.
URLs usually have the form, http://www.example.com/index.html, which indicates the protocol (http), a
hostname (ww.example.com), and a file name (index.html).
All URLs are URIs, but not all URIs are URLs.
