                     Internet/Web security terms                                 

Encryption:   ''encryption is the process of converting data to an unrecognizable or "encrypted" form. It is commonly used to protect sensitive information so that only authorized parties can view it. This includes files and storage devices, as well as data transferred over wireless networks and the Internet.''

Captcha: Completly Automated Public Turing test to tell Humans and |Computers Apart

''A captcha is a program used to verify that a human, rather than a computer, is entering data. Captchas are commonly seen at the end of online forms and ask the user to enter the text from a distorted image. The text in the image may be wavy, have lines through it, or maybe highly irregular, making it nearly impossible for an automated program to recognize it. (Of course, some captchas are so distorted that they can be difficult for humans to recognize as well.) Fortunately, most captchas allow the user to regenerate the image if the text is too difficult to read. Some even include an auditory pronunciation feature.''

Firewall:    ''A physical firewall is a wall made of brick, steel, or other inflammable material that prevents the spread of a fire in a building. In computing, a firewall serves a similar purpose. It acts as a barrier between a trusted system or network and outside connections, such as the Internet. However, a computer firewall is more of a filter than a wall, allowing trusted data to flow through it.''

Shareware:     ''Shareware is software that you can use on a trial basis before paying for it. Unlike freeware, shareware often has limited functionality or may only be used for a limited time before requiring payment and registration. Once you pay for a shareware program, the program is fully functional and the time limit is removed.''
