Fiber optics is one of the technologies used to transmit data through thin glass or plastic fibers. It is mostly used in communication channels like telephone, televisions, and the Internet. Core and cladding are two parts of fiber optic cable. The cladding reflects the light to the core, thus preventing the loss of signal. Fiber optics are mostly used in medical and industry services. In the medical field, it is used for endoscopies, to view and treat internal organs. In industries, it is used in controlling temperature, pressure, and vibrations. Fiber Optics and its Types Definition Fiber optics is defined ... Read More

In ISO OSI layers there are seven layers, and each layer has its characteristics and its protocols. The most important second layer from the bottom is the data link layer. In this data link layer consists of two different layers and MAC is one important layer. MAC is the Medium Access Control layer. MAC layer helps to reduce the collision while transmitting the data. The main functionality of the MAC layer will act as a medium to access the shared resources in the network. So it has the control accessibility of nodes when they are in a shared medium. MAC ...
