Web and Internet Terminology

We will review these terms in class. Here is a good online resource that explains how web servers work.

  • Web browser (client) -- Used to view web documents stored as a file on your computer or access from a web server on the internet.
  • Web server -- Hosts web pages. A web browser can access a web page from the web server on the internet.
  • HTTP (Hyptertext Transit Protocol) -- communication protocol for accessing a web page from a web server.
  • SFTP (Secure File Transfer Protocol) -- secure protocol for transferring files to a remote computer. We will use FileZilla (sftp program) to transfer (upload) web HTML files from your computer to a Web server. FTP (File Transfer Protocol) is a less secure method for transferring a file.
  • Host Name -- name given to a computer, often a web server (e.g. studentweb.cdm.depaul.edu).
  • URL (Uniform Resource Locator) -- serves as the address for accessing a web page on the internet. Used for accessing other documents too.
  • Client-side scripting -- the web browser performs all calculations
  • Server-side scripting -- the web server performs the calculations whose results are then displayed by the web browser

Here is an example URL: http://condor.depaul.edu/~cmiller/myPage.html

  • http specifies the protocol
  • condor.depaul.edu specifies the host name of the web server
  • ~cmiller/myPage.html specifies the location and file name on the web server
