Because LDAP is also utilized to query for sensitive or Active Directory information such as user names, and network service locations; it is easy Read More

CLASSPATH is an environment variable which tells the Java compiler and the JVM where to look for Java class files. In Java 1.2 and later, the CLASSPATH variable is less critical because Java knows how to find the default classes and because Java loads classes from the current directory by default. If you do not want to use an environment variable, you can use the -classpath argument to the Java compiler or the JVM as such: javac -classpath . JavaProg To add a jar file to your CLASSPATH, include the Read More

MMX stands for Multimedia Extensions. MMX is a technology designed to accelerate multimedia and communications applications. This acceleration and simplification is done through a set of multimedia instructions which are built into microprocessors to enable them to handle common multimedia operations like DSP, or Digital Signal Processing. MMX works by taking certain operations, such as moving a pixel of graphics, which are usually processed as 8-bit integers, and instead packing a number of these pixels into one larger data unit. MMX then performs the requested operation on the larger data Read More

Noise-canceling headphones are headsets that have the ability not just to block out noise but to cancel it using the properties of sound waves. Sound waves have compression and rarefaction characteristics similar to the crests and troughs of a transverse wave. They also have amplitude and frequency characteristics. These characteristics of sound waves are used in noise cancellation by noise-canceling headphones. The first noise-canceling headphones were manufactured by Bose and quickly found a market especially among musicians. Their popularity came from their ability to filter out and eliminate the white Read More
