      E To amplify signals and extend the range of a network’s coverage area. Correct Answer Incorrect Answer

      Solution

      A gateway serves as an interface between different networks that use different protocols or architectures. Its primary function is to translate and convert data from one format or protocol into another, facilitating communication between systems that would otherwise be incompatible. Gateways operate at various layers of the OSI model, depending on the type of data conversion required. For example, a network gateway might translate between different network protocols (like TCP/IP to X.25) or between different types of network technologies (like a private network to the public Internet).
