Q: In the Transmission Control Protocol/Internet Protocol (TCP/IP) paradigm, which layer is in charge of establishing a standard for signal interpretation so that network devices may interact with one another?
- Data link
- Application
- Transport
- Network
Explanation:Â The “Link layer” or “Network Interface layer” is the TCP/IP model layer that is responsible for providing a standard mechanism to interpret signals so that network devices may interact with one another. This is done at the “Link layer.” In the OSI model, this layer corresponds to both the Data Link layer (Layer 2) and the Physical layer (Layer 1). It discusses the hardware-specific specifics of how signals are conveyed across the network medium and how devices on the same network understand these signals. It also discusses how signals are received by devices on the same network. The framing, addressing, and error-checking procedures that are required for dependable communication on a local network segment are encapsulated in the Link layer of the networking stack.
