Wintel-based System Wintel refers to a computer based on a Windows operating system and an Intel microprocessor. The terms virus and worm are too limiting to cover all the new sorts of rogue traveling programs. To be considered malicious mobile code, an ill program must intentionally modify a user's system without their permission and contain coding to facilitate its transfer between different computers. A macro is a predefined shortcut used to automate a particular series of keystrokes or automate a program feature. For example, in most Windows programs, hitting Ctrl-S will save a file just as choosing File, Save and Enter from the program's menu bar.
Macro languages allow very sophisticated macros, and entire other applications, to be developed.
Internet Relay Chat Internet Relay Chat allows two or more computers to send instant messages to each other. There are tens of thousands of IRC channels, each dedicated to a particular topic. Hackers use IRC to communicate to other hackers, to trade programs, and to announce the latest system invasions. Active Content Active content refers to any program coding or scripting that can manipulate a user's system. Most often, active content is initialized from within an Internet browser, but it can be started in other applications - notably email.
