applet definition World-Wide Web
program which can be distributed as an attachment in a World-Wide Web
document and executed by a Java-enabled web browser
such as Sun's HotJava
, Netscape Navigator
version 2.0, or Internet Explorer
Navigator severely restricts the applet's file system and network access in order to prevent accidental or deliberate security violations. Full Java applications, which run outside of the browser, do not have these restrictions.
Web browsers can also be extended with plug-ins
though these differ from applets in that they usually require manual installation and are platform
-specific. Various other languages can now be embedded within HTML
Despite Java's aim to be a "write once, run anywhere" language, the difficulty of accomodating the variety of browsers in use on the Internet has led many to abandon client-side processing in favour of server
-side Java programs for which the term servlet
Merriam Webster "Collegiate Edition" gives a 1990 definition: a short application program especially for performing a simple specific task.
