The ST connector was the first defactor standard for fiber optic cabling. It was first developed by AT&T. ST connectors were leading connectors in the late 80s and early …
FCAPS is an ITU standard model for enterprise management. The five FCAPS domains are: Fault Management Configuration Management Accounting Management Performance Management Security Management Fault Management Fault management is the domain where network problems are discovered and corrected. Steps are then taken to prevent them from occurring or recurring. By doing so, the network remains …
The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with …
Multicast is the transfer of messages to multiple destinations simultaneously, using fewer networks. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. Multicasting reduces unnecessary packet duplication. A wireless network utilizes radio communication, unlike wired networks, …
A DHCP scope is a valid range of IP addresses that are available for assignment or lease to client computers on a particular subnet. In a DHCP server, a scope is configured to determine the address pool of IPs that the server can provide to DHCP clients. Scopes determine which IP addresses are provided to …
A smart antenna is one that transmits or receives multiple radio frequencies at once. Smart antennas increase data transfer rates and reduce errors by handling several copies of the same information. Conventional antenna systems consist of one antenna that serves as a transmitter and one that serves as a receiver. This is starting to change, …
Wireless routers are network devices that combine the functionalities of a router and a wireless access point. Wireless routers can be connected to broadband modems to provide wireless access to the Internet to two or more computers or laptops within a home environment.
