Which of the following is a data link protocol?
Data link protocols are essential in networking for reliable communication between adjacent network nodes. These protocols manage the data transmission across the physical link and ensure error-free delivery. Some common data link protocols include:
Ethernet 🖧: Widely used in local area networks (LANs), Ethernet ensures data frames are sent and received correctly between devices.
Point-to-Point Protocol (PPP) 🔗: Used in direct connections between two network nodes, such as between a computer and an ISP.
HDLC (High-Level Data Link Control) 📡: A bit-oriented protocol used in wide area networks (WANs) for ensuring the correct delivery of data across the network.
These protocols ensure that data travels accurately and efficiently across the physical medium, forming the backbone of effective network communication.
