Function overloading is a concept where several function declarations are specified with a single and a same function name within the same scope. Such functions are said to be overloaded. C++ allows functions to have the same name. Such functions can only be distinguished by their number and type of arguments. Example: float divide(int a, int b) ; float divide(float a, float b) ; The function divide(), which takes two integer inputs, is different from the function divide() which takes two float inputs. What is the need for function overloading? Read More

Jets are able to move much faster than other types of aircraft and they especially move faster than regular forms of transportation such as trains and automobiles. In exchange for all the extra speed, however, jet engines must be designed and built differently than normal engines. This article will explain what jet engines do that are so special and list a number of parts that are crucial to the jet engine's ability to generate such high speeds. What Do Jet Engines Do Jet engines, also known as gas turbine engines, Read More

A metal detector uses an electromagnetic field to detect the presence of a concealed metal object. The range depends on the strength of the field, and is usually less than one meter from the search head. The three detection methods are beat frequency oscillation, very low frequency, and pulse induction. Metal detectors were first introduced around 1930 and are used in many different applications. How Metal Detectors Work The beat frequency oscillation method uses two coils connected to an oscillator. When the search head coil passes over a metal object, Read More

802.1Q is also known as IEEE 802.1Q or VLAN tagging. It defines a virtual local area network. It is a protocol that allows virtual LANs to communicate with one another using a 3-layered router. It was developed as a part of IEEE 802. Why Was The 802.1Q Standard Developed? Large networks use up a lot of bandwidth and are slow. It is desirable to break up these huge LANs into smaller, more manageable networks. To address this problem, the 802.1Q standard was developed as a part of IEEE 802. This Read More
