| − | == | + | =='''World Wide Web (WWW)'''== |
| − | + | <div align=justify>''The World Wide Web'', abbreviated as WWW and often referred to as the Web, is a system of interlinked hypertext documents which can be accessed via the Internet. You can view web pages using a web browser. | |
| − | ==Webpage== | + | =='''Hypertext Markup Language (HTTP)'''== |
| + | Shortening for ''HyperText Transfer Protocol'' is the basic protocol used by the World Wide Web. HTTP defines the way the messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, each time you enter a URL in your browser address bar, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page. | ||

| + | =='''Webpage'''== | ||
Each web page (also known as webpage) represents various types of information presented to the visitor and makes it readable and nice-looking. Most of the web pages can be accessed on the World Wide Web via a web browser. This makes them widely accessible to the Internet public. | Each web page (also known as webpage) represents various types of information presented to the visitor and makes it readable and nice-looking.

| − | ==How does a webpage work?== | + | =='''How does a webpage work?'''== |
| + | The web page information is displayed online with the help of a web browser, which connects to the server where the website's files are hosted through the Hypertext Transfer Protocol (HTTP). For example, if you look at the URL of the web page you are currently on, you could notice the prefix http://. This tells the browser what protocol to use to execute this particular URL request. | ||
| − | + | Each web page is usually presented in HTML or XHTML format, which makes the information easily structured and then read by the client's web browser. With the help of CSS (Cascading Style Sheets), designers can control and modify the web page's look (i.e. layout, color scheme, navigation, etc.) CSS instructions can be either set within the HTML web page (valid for a definite page) or can be included in a separate external file (valid for the whole site). | |

| − | == | + | =='''Web browsers'''== |
| − | + | A web browser is a computer program designed to read HTML or PHP code, composing the web pages. There is a great number of web browsers nowadays and all of them are based on different browser engines, which read HMTL and PHP code and present it as a readable page screen. Web browsers were found in the 1980s and are being constantly developed and upgraded to provide faster loading times, more stable web pages and better looking websites. | |
| − | == | + | =='''URL'''== |
| − | The | + | ''The Uniform resource locator'' (known as URL) is the global web address of text, images and other file that compose a web page. It locates a document or a program available on the web and specifies the mechanism for accessing it via a web browser. |
| − | ==File== | + | =='''What is an ISP?'''== |
| + | The ISP, short for ''Internet Service Provider'', is the company that provides access and connects your personal computer, notebook, mobile device, etc. to the Internet. Another name for ISP is IAP, or Internet Access Provider. | ||
| + | |||
| + | =='''File'''== | ||
A computer file is a block of information (e.g. a text file is composed by a block of characters). It is also used as a resource for storing information, available to a computer program. The file is a basic carrier of information in the process of global data transfer that Internet and other high technologies are based on. It represents a consistency of characters that are stored on a personal computer or on a web server, viewable from any computer connected to the Internet. | A computer file is a block of information (e.g. a text file is composed by a block of characters).

| − | ==Website== | + | =='''Website'''== |
| + | A Web site is a related collection of World Wide Web (WWW) files (text, images, etc.) that includes a beginning file referred to as a home page. To get to the company's or individual's website you just need to ask them for the site's home page address. From the home (start) page you can get to all other pages on the site. For example, the Web site for google.com has the home page address of http://www.google.com. (Generally the home page is named either index.html or index.php as index file is the one that starts loading automatically when a site name is entered into a browser. So the users do not have to type http://www.google.com/index.html). A web site may have thousands of pages or there may be just a single home page. | ||
| + | |||
| + | =='''Bandwidth'''== | ||
| + | The term ''bandwidth'' stands for the speed of data being transferred over the Internet from the data centers it is located in to the Internet Service Providers and to the users' Internet enabled devices. | ||
| − | == | + | =='''Web Space'''== |
| + | The web space, also referred to as storage space or disk space, generally stands for the amount of space on a web server that is allocated to website owners by the web hosting companies. It is made up of the total quantity of all files related to your website (documents, images, emails, etc.) | ||
| − | ==Web | + | =='''Web Server'''== |
| + | A computer that delivers (serves up) Web pages. Every single Web server has an IP address and a domain name (in most cases). For example, if you type the URL http://www.google.com/index.html in your web browser, this sends a request to the server whose domain name is google.com. The server then fetches the page named index.html and sends it to your browser. | ||
| − | + | Any computer can be used as a Web server after installing the needed server software and connecting the machine to the Internet.</div> | |
