Link Layer

The Link Layer is a part of computer networking that handles the communication between devices directly connected on the same network, like computers or printers connected to a Wi-Fi or Ethernet. It ensures data is transferred reliably and correctly from one device to another, managing how data frames are formatted, addressed, and checked for errors. Think of it as a translator and messenger between devices, making sure messages are sent smoothly over local connections before they move on to longer-distance networks.
