_____________1. The Internet is made of many computers connected to each other through 'Communication-Lines'
True
False
Additional Comments:
Broadband over power lines (BPL), also known as power-line Internet or Powerband, is the use of PLC technology to provide broadband Internet access through ordinary power lines. A computer (or any other device) would need only to plug a BPL 'modem' into any outlet in an equipped building to have high-speed Internet access. BPL seems, at first glance, to offer benefits relative to regular cable or DSL connections: the extensive infrastructure already available would appear to allow people in remote locations to have access to the Internet with relatively little equipment investment by the utility. Also, such ubiquitous availability would make it much easier for other electronics, such as televisions or sound systems, to hook up. PLC modems transmit in medium and high frequency (1.6 to 80 MHz electric carrier). The asymmetric speed in the modem is generally from 256 kbit/s to 2.7 Mbit/s. In the repeater situated in the meter room the speed is up to 45 Mbit/s and can be connected to 256 PLC modems. In the medium voltage stations, the speed from the head ends to the Internet is up to 135 Mbit/s. To connect to the Internet, utilities can use optical fiber backbone or wireless link. Power line communication (PLC), also called power line carrier, mains communication, power line telecom (PLT), or power line networking (PLN), are terms describing several different systems for using electric power lines to carry information over the powerline.
_____________2. The URL, or Web-Address, displayed in the address bar generally indicates:
(a) The name and location of the current document
(b) The Size of the currently displayed document
(c) Your favorite link
(d) The Availability of the Server.
_____________3. The Microsoft's Internet Explorer enables the user to:
(a) Create professional graphics (An image that is generated by a computer i.e. Icon or pictures)
(b) Visit the World Wide Web (Computer network consisting of a collection of Internet sites that offer text and graphics and sound and animation resources through the hypertext transfer protocol-HTTP)
(c) Configure your Windows System (Instrumentality that combines interrelated interacting artifacts-A man-made object taken as a whole designed to work as a coherent ordered and logical entity)
_____________4. What generally happens when user click a link, or Hyperlink? (A link from a hypertext {Machine-readable text that is not sequential but is organized so that related items of information are connected, It is a part of object-oriented database, Hyperlink or link has two ends: A Source and a Destination} file to another location or file; typically activated by clicking on a highlighted word or icon at a particular location on the screen)
(a) The Internet Explorer (A commercial browser which is part of MS Windows - A Software/ application program {A program that gives a computer instructions that provide the user with tools to accomplish a task} used to view/ browse HTML documents) program closes.
(b) The document (a computer file that contains text (and possibly formatting instructions) using seven-bit ASCII characters) represented by the link is displayed.
(c) The current document is redisplayed.
(d) You're prompted to enter the URL (The address of a web page on the world wide web known as uniform resource locator or universal resource locator) of the document.
_____________5. To return to pages you've visited, you use which buttons?
(a) Back and Forward
(b) Back and Home
(c) Stop and Refresh
(d) Back and Refresh
_____________6. What enables the user to access other pages on the World Wide Web, which can be offered by any organization in the world?
(a) Text (textual matter - The words of something written)
(b) Pictures (A visual {optical or Visible} representation (of an object or scene or person or abstraction) produced on a raster or vector surface
(c) Navigation (The mechanism through which a user on WWW travels from one webpage {A document connected to the World Wide Web and viewable by anyone connected to the Internet who has a web browser} to another or from one location to another)
(d) Sound (Utter with vibrating vocal chords or which make a certain noise and which could be a particular auditory effect produced by a given cause i.e. Voice or noisiness)
(e) Videos (The visible part of a transmission (computer science - visual communication {Communication that relies on vision}) the appearance of text and graphics on a video display)
(f) None of these
Additional Comments:
Navigation: For a successful navigation design, it's important to consider the interface as well. The interface is the intermediary between users and content, an interpreter and guide to the complexities of a site. In the graphical environment of the Web, interface design has to do with constructing visual meaning. The happy marriage of architecture and interface--of logical structure and visual meaning--creates a cohesive user experience. This marriage is crucial to helping users get around on the Web.
_____________7. Web Pages are written in a special programming language called as:
(a) Hypertext Markup Language {A set of tags and rules (conforming to SGML - a standardized language for the descriptive markup of documents; a set of rules for using whatever markup vocabulary is adopted - “Standard generalized markup language”) for using them in developing hypertext documents}
(b) XML (Extensible {Extensible because XML allows the author to define his own tags and his own document structure} Markup Language; used for describing data in a structured text format)
(c) Both
_____________8. Web-Page links can be represented by:
(a) Underlined words only
(b) Buttons only
(c) URLs in the address bar
(d) Underlined words, pictures and graphic text
_____________9. You can enter a URL into the “Address Bar” by:
(a) Typing it in or choosing it from “Auto-Complete” list
(b) Clicking a link on the page.
(c) Clicking the Go Button
(d) Pressing “Enter”
_____________10. When you encounter a browser error, you can remedy the problem by:
(a) Retyping the URL
(b) Check your connection to the Internet
(c) Go back to the previous web-page you've visited
(d) All of the above
