2262
What is the term used to describe a version of software that is released before the final version?
Answer:
Beta
In the software release life cycle, a beta version is a pre-release version of software that is given to a group of users for testing before its official release. This stage follows the internal alpha testing phase and helps identify bugs and gather feedback.

2269
The Java programming language is famous for its "write once, run anywhere" philosophy. This is achieved by compiling Java source code into an intermediate form called:
Answer:
Bytecode
The Java compiler converts source code into platform-independent bytecode. This bytecode is then executed by a Java Virtual Machine (JVM), which is an interpreter tailored for the specific operating system, allowing the same bytecode to run on any system with a JVM.
2270
Which type of software is designed to operate and control the computer hardware and provide a platform for running application software?
Answer:
System Software
System software acts as the intermediary between the computer's hardware and the application programs. The operating system is the prime example, managing resources and providing essential services.
