PAM DefinitionPAM is pluggable authentication module. This is a mechanism to integrate multiple low-level authentication schemes into a high-level application programming interface (API). It allows programs that rely on authentication to be written independently of the underlying authentication sche

Definition:Optical Ethernet is the physical layer of the Local Area Network (LAN) communications protocol for sending data over fiber-optic cable. It is used for connecting Internet servers and switches inside equipment racks, within data centers, and between metropolitan data centers. Today the mos

Definition:An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in

Definition:A gigabit interface converter (GBIC) is a standard for transceivers, commonly used with Gigabit Ethernet and fiber channel in the 2000s.[citation needed] By offering a standard, hot swappable electrical interface, one gigabit port can support a wide range of physical media, from copper to

Definition:A gigabit interface converter (GBIC) is a standard for transceivers, commonly used with Gigabit Ethernet and fibre channel in the 2000s. By offering a standard, hot swappable electrical interface, one gigabit port can support a wide range of physical media, from copper to long-wave single

DefinitionA fiber media converter is a simple networking device that makes it possible to connect two dissimilar media types such as twisted pair with fiber optic cabling. They were introduced to the industry in the 1990s, and are important in interconnecting fiber optic cabling-based systems with e

Definition:Linux Pluggable Authentication Modules (PAM) provide dynamic authentication support for applications and services in a Linux or GNU/kFreeBSD system. Linux PAM module is evolved from the Unix Pluggable Authentication Modules architecture. Linux PAM module uses a pluggable, modular architec

Definition:IEEE 802.3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer‘s media access control (MAC) of wired Ethernet. This is generally a local area network technology with some wide area network applications. Physic

DefinitionFiber optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber optics have revolutio
