Which device provides the necessary translation of data received from the network into a format recognized within the internal network?
- Bridge
- Gateway
- Router
- Modem
The Correct Option is B
Approach Solution - 1
To understand which device translates data for internal network recognition, we must examine the function of each provided option:
- Bridge: Primarily connects and filters traffic between two network segments. It does not perform data format translation.
- Gateway: Operates as a "translator" between networks that use different protocols, handling data format conversion to ensure it is compatible with the destination network.
- Router: Directs data packets based on their IP address but does not modify the data format.
- Modem: Modulates and demodulates signals for Internet connectivity but does not translate data formats for internal networks.
Based on these roles, the Gateway is the correct device, as it provides the necessary translation of data received from one network into a format recognized within another network.
Approach Solution -2
(1) Bridge: A bridge connects two network segments, typically within the same network, and filters traffic based on MAC addresses. While it can perform some data conversion, its primary function isn't translating data formats between different network protocols.
(2) Gateway: A gateway connects networks that use different communication protocols. It performs the necessary translation and conversion of data formats to allow communication between these disparate networks.
(3) Router: A router forwards data packets between networks based on IP addresses. It determines the best path for data to travel but doesn't primarily focus on translating data formats between different protocols.
(4) Modem: A modem modulates and demodulates signals for transmission over communication channels, such as telephone lines. It's not directly involved in translating data formats between networks.
Therefore, the device that provides the necessary translation of data received from a network into a format or protocol recognized by devices within the internal network is a (2) Gateway.
