1. Is the signal energy mechanical or electromagnetic? Sound energy is mechanical and radio frequency/microwave and optical/laser transmissions are electromagnetic.

2. What is the signal carrier frequency and bandwidth? The bandwidth of speech ranges from 20 Hz to 20 KHz but radio frequency transmitter frequencies can vary tremendously depending on the device. The power of the radiated signal is an important factor in estimating vulnerability to unauthorized signal detection that potentially leads to information loss.

3. What are the intervening materials between the signal source and the receive location? Recognize that signals often take multiple indirect routes in arriving at a destination. Understanding the effect of materials as a function of signal frequency will enhance the accuracy of estimates of the vulnerability component of risk.

A Java Virtual Machine (JVM) is a set of computer software programs and data structures which use a virtual machine model for the execution of other computer programs and scripts. The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode. This language conceptually represents the instruction set of a stack-oriented, capability architecture. As of 2006, there are an estimated 4 billion JVM-enabled devices worldwide.

Java Virtual Machines operate on Java bytecode, which is normally (but not necessarily) generated from Java source code; a JVM can also be used to implement programming languages other than Java. For example, Ada source code can be compiled to Java bytecode, which may then be

Switch2Citect is a software conversion tool that helps you to migrate legacy HMI/SCADA software systems to the world-class CitectSCADA software with less risk, cost and effort.

Switch2Citect also gives you the ability to have full control over the conversion process so that you can improve your legacy system by adding new functionality, improving the maintainability and incorporating corporate standards.
