Internet today is not a luxury, or something unusual and surprising.It is an everyday tool for work and leisure, communication and information exchange.That is why many users at the same time or shortly after the acquisition of the first computers to connect to the "World Wide Web."At the same few people think of the connection procedure.And even fewer people pay attention to the technical aspects of the work of a service provider.At the same time we need to understand the principles of networking and know what mac-address, LAN, router, switch, etc."Why?" - Asks a surprised reader is only interested in stocks and prices of different providers.It's simple!Knowledge of network technology - a guarantee of choosing a reliable provider, which means that the subscriber will occur less cause for complaint on the Internet connection and contact with technical support.
