Understanding the Function of Protocols Protocols are rules, standards and procedures that enable information to be communicated in the network environment. The rules and standards that control the way in which computers communicate are referred to as protocols. A few relevant factors to consider when discussing protocols and the network environment are: There are numerous protocols Each protocol has a specific set of functions that assist in enabling communication over the network. The layer of the OSI reference model at which the protocol operates indicates its function. Certain protocols can Read More

An IXC (Inter-eXchange Carrier) is a telephone company that is responsible for handling long distance telephone calls. A long distance telephone call refers to any call made to an area outside of the caller’s LATA (Local Access and Transport Area), which the caller’s local telephone company usually handles. While local telephone companies may forward a long distance call to an IXC, which will then forward the call to a phone company in the recipient’s LATA, most telephone companies serve as both local and long distance carriers. How IXC Works If Read More

An environment variable is a variable that describes the way a computer environment, such as an operating system, works. Environment variables can be used to manage a wide variety of environment settings and control how functions are carried out. For example, an environment variable can be used to specify the directory in which temporary files are stored or the functions a user interface tool is able to perform.   How Environment Variables Work Environment variables are integrated into any software’s script before the software is released. Since environment variables control Read More

Socket-370 is a CPU socket utilized by some Celeron, Pentium III, and Via C3 processors. The “370” in Socket-370 means that the socket has 370 contacts. The socket-370 is a Pin Grid Array (PGA) Zero Insertion Force (ZIF) socket. A ZIF socket features a lever on one side of the socket. When this lever is pulled up, the spring contacts inside the socket are opened. This allows the CPU to be inserted easily into the socket. The lever is then pushed down, closing the spring contacts and clamping the CPU Read More

Transconductance is a property of some electronic components and is also known as mutual conductance. It is the opposite of resistance. The measure of transconductance is the ratio of the electrical current change at an output port as compared to the voltage change at the input port. The measure of transconductance is commonly used in reference to vacuum tube ratings as well as other electronic devices. Devices With Measurable Transconductance Vacuum tubes, bipolar transistors, field effect transistors, and amplifiers typically have a measurable transconductance value. In vacuum tubes, it is Read More

WD 40 is a clever name for a waterproofing solution. WD-40 literally means “Water Displacement 40th attempt.” It contains hydrocarbons which propel the oils to prevent the wetness of water from reaching the coated surfaces. It has numerous uses as a household tool and is currently available worldwide. The hydrocarbons were then replaced with carbon dioxides as a safety measure later on. The company has been in business ever since 1958 when WD 40 was invented. It was originally designed to coat the SM-65 Atlas Missile to prevent rusting and Read More
