- Applets
- Definition: Code objects sent from a server to a client to perform specific actions. They are self-contained programs that run independently of the server that sent them.
- Execution: Applets are designed to operate on the client’s system, providing interactive features without needing to constantly communicate with the server.
- Java Applets
- Definition: Short Java programs transmitted over the Internet to perform operations on a remote system.
- Execution: Java applets are platform-independent and can run on any system with a compatible Java Virtual Machine (JVM).
- ActiveX Controls
- Definition: Microsoft’s version of applets, implemented using various programming languages such as C, C++, and Java.
- Key Differences from Java Applets:
- Proprietary Technology: ActiveX controls use proprietary Microsoft technology, meaning they can only run on systems using Microsoft browsers.
- Execution: Unlike Java applets, ActiveX controls are not restricted by a sandbox environment, granting them full access to the Windows operating environment, including the ability to perform privileged actions.
These concepts are important for understanding how different types of applets and controls function in web environments, particularly regarding security and platform compatibility.
