Computer networks also let us to make use of assets a lot more efficiently. By way of example, corporations can build one network printer accessible by Every person or a single shared storage push instead of paying for independent storage for each computer.
Synchronous optical networking (SONET) and Synchronous Electronic Hierarchy (SDH) are standardized multiplexing protocols that transfer many digital bit streams about optical fiber using lasers. They were originally developed to transport circuit mode communications from a variety of various resources, primarily to aid circuit-switched electronic telephony.
Versatility. Present day computer networks allow people to employ adaptable interaction and source-sharing strategies centered on their own demands and Choices.
