SUB-TOPIC 1: Basic Terminologies

1. WWW: The word World Wide Web or simply put a web is a means of accessing, organising, and moving through the information over the internet. It is the user friendly ‘point-and –click way of navigating data stored on computers connected to the internet facilitated by the hypertext that provides links between one website and the another.
2. Website: A website is a collection of documents of pages, the first of which is called HOME PAGE. It is the opening page of an internet website. It also refers to someone’s personal website on the internet, which may contain the owner’s personal data, photograph or contact information
3. Protocol: This is a set of technical rules for the transmission and receipt of information among computers in the network.
4. Uniform Resource Locator: This refers to an internet address. It is an address identifying the location of a file on the internet. It consists of the protocol, the computer on which the file is located and the file’s location on that computer. It can be compared to an address where a particular document resides. An example is http/www.rhemabooks.com/publication/computer studies.html
5. Web Page: A webpage is a unit of a website. It is like a page or chapter in a book, which gives concise information on an aspect of the entire website. Each webpage within a website is a file, which has its own uniform resource locator (URL).
6. Hypertext: This is a text displayed on a computer or other electronic devices with references (hyperlink) to other texts that the reader can immediately access, usually by a mouse click or key press sequence.
7. Hyperlink: Hyperlink is a reference to a document that the reader can directly follow or that is followed automatically. It points to a whole document or to a specific element within a document. A user following a hyperlink is said to be navigating, or browsing the hypertext.
8. Uniform Resource Identifier: A URI is a string of characters used to identify a name or resource in the internet. It may refer either to a name, numerical or other form of identification used on the internet.
9. Internet Protocol (IP) Address: This is an identifier assigned to each device connected to a network that uses the internet protocol for communication. Each device must have a unique IP address within the specific network segment. It can be compared with a physical address that uniquely identifies a particular street address.
