What Does Extremely Low Frequency (ELF) Mean? Extremely low frequency (ELF) is the designation given by the International Telecommunication Union (ITU) for radio waves or electromagnetic radiation with frequencies that range from just 3 Hz to 30 Hz and with corresponding wavelengths. But in atmospheric science, ELF is alternatively given a range of 3 Hz to 3,000 Hz. ELF signals are usually generated by naturally occurring phenomena such as lightning strikes and natural disturbances in the earth....

What Does N Port ID Virtualization (NPIV) Mean? N_port ID virtualization (NPIV) is a technique that enables the sharing of a single fiber channel N_port between multiple N_ports. It is used in storage networking techniques that utilize fiber channel-based ports to send and receive data between virtual machines (VM) and virtual storage area networks (SAN). NPIV is a component of the Fiber Channel Link Services (FC-LS) specification. Techopedia Explains N Port ID Virtualization (NPIV) NPIV is used in virtual storage area networks (VSAN) that reside on a consolidated physical SAN server with limited fiber channel ports....

What Does Power Control Mean? In telecommunications, power control refers to the process of controlling the power of a transmitter to achieve better communication signal or overall quality of service. It is mainly used to control the transmitting power of a communication device to achieve better performance.
