What is Java Virtual Machine?

Java Virtual Machine (JVM) is a set of computer software programs and data structures which implements a particular virtual machine model. This model agrees to a form of computer intermediary language, normally referred to as Java bytecode, which conceptually signifies the instruction set of a stack-oriented, capability architecture. This code is primarily often generated by Java language compilers, even though the JVM can as well be targeted by compilers of other languages. JVMs using the "Java" trademark can be developed by other companies as extensive as they adhere to the JVM requirement published by Sun and related to contractual obligations.

The JVM is a crucial part of the Java Platform. Since the JVMs are accessible for many hardware and software platforms, Java can be equally middleware and a platform has its own right — therefore the expression "write once, run anywhere." The use of the alike bytecode for every platforms allows Java to be described as "compile once, run anywhere", as opposed to "write once, compile anywhere", which denotes cross-platform compiled languages. The JVM as well enables such exclusive features as Automated Exception Handling which gives 'root-cause' debugging information for all software error (exception) independent of the source code.

What can a C program and Programming Language do?

A Typical programming task includes putting data into a database or pulling it out, displaying high speed graphics in a game or video, managing the electronic devices joined to the PC or even playing music and/or sound effects. You can even write down software to generate music or help you to compose.

A programming language is used to write down computer programs like Applications, Utilities, Servers and Systems Programs.

A program is written as a series of human comprehensible computer instructions that can be read by a compiler and linker, and translated into machine code so that a computer can know and run it in programming language.

What does it mean by unmanned space missions?

The unmanned space missions are those using the remote-controlled spacecraft. The first such mission was the Sputnik I mission, began on October 4, 1957. Few missions are more appropriate for unmanned missions rather than manned space missions, as a result of lower cost and lower risk factors. Because the early 1970s, most unmanned space missions have been based on space probes with the built-in mission computers, and as such possibly will be classified as embedded systems.

What is electronic mixer?

Electronic mixers are a device and are used for mixing two or more electronic signals. There are two fundamental types of mixer. The one is the additive mixers and the other is multiplying mixers. The Additive mixers add two signals jointly, and are used for that kind of or such applications as the audio mixing. The Multiplying mixers multiply the signals jointly, and make or produce an output containing together original signals, and new signals that have the sum and difference of the frequency of the original or the innovative signals.
