Simply put: it is the **bridge between "bits" and "packets."** --- ## The data link layer's place in the OSI model The OSI model consists of **7 layers** (bottom to top): 1. **Physical layer** - transmits bits (0 and 1) 2. **Data link layer** - **HERE** 3. Network layer 4. Transport layer 5. Session layer 6. Presentation layer 7. Application layer --- ## What this means in practice - **Below the data link layer** just electrical/optical/radio signals - **The data link layer itself** gathers bits into **frames**, adds **MAC addresses**, checks for errors - **Above the data link layer** routing logic, IP addresses, and packets begin --- ## Short answer for an interview > **The data link layer is the second layer of the OSI model**, located between the physical and network layers, which delivers data as frames within a single network.For the reviewerNote to the moderator (optional)Visible only to the moderator.
