Where PI and P2 are the variable and the powers of a signal at points 1 and 2, respectively. This noise may corrupt the signal.

Together, these three recommendations are often called "triple X". Series of interface points that allow other computers to communicate with the other layers of network protocol stack.
A generic term for section of a large networks usually separated by a bridge or router. What Is Subnet Mask? It is a term that makes distinguish between network address and host address in IP address. Subnet mask value 0 defines host partition in IP address and value 1 — defines Network address. Describe Various Network Type? Local Area Networks Local area networks LANs are used to connect networking devices that are in a very close geographic area, such as a floor of a building, a building itself, or a campus environment.
Companies deploy basically two types of CNs: Distributing Internet traffic loads across multiple servers Storage Area Networks Storage area networks SANs provide a high-speed infrastructure to move data between storage devices and file servers. Disadvantage of SANs is their cost.
