An Internet scam in which corrupt parties "phish" (pronounced "fish") for your personal information by attempting to lure you to click on a link in an email. You will then be directed to what looks like an official web site, where you'll be encouraged to enter personal information. The fake web site appears as though it is that of a real company (with which you might have a relationship) but it is merely a means to steal information.
A pop-up is a small window or mini-Web page that "pops up" on your monitor when you visit a web site or click a link that activates it. Pop-ups are best known for displaying advertising on web sites, but they are also used to present photo enlargements (when you click on a thumbnail photo), or as small control panels conveniently separated from a main page. You can close a pop-up by clicking a button or link word; some are programmed to close after a set number of seconds or minutes. A pop-up is essentially the same as any other web page except that it usually appears in a much smaller format and contains only content -- no tool panels, status bar, etc.
A proxy server is a kind of server (a computer that delivers or "serves" information to other computers). The proxy links the user (often the Web browser on your personal computer, or a computer in a network or group) and another main server. The proxy can store information, so that if more than one user requests the same data, it delivers it, eliminating the need to tie up the main server. The proxy can also filter transmissions, and is often used in workplace networks to screen out unwanted communications.
PPP is the standard for the Internet data transfer technology known as serial communications. Its predecessor, SLIP (Serial Line Internet Protocol), was less stable and had fewer functions. PPP defines how your modem connection exchanges packets of data with other systems on the Internet; it can also compress data and detect errors in the transmission.
