Switch is a Device of __________ Layer of OSI Model.Network LayerData Link LayerApplication LayerSession Layer

Break Down the Problem

1. Identify the function of a switch.
2. Determine which layer of the OSI model corresponds to the function and operation of a switch.

Relevant Concepts

• The OSI (Open Systems Interconnection) Model has seven layers:
  1. Physical
  2. Data Link
  3. Network
  4. Transport
  5. Session
  6. Presentation
  7. Application
• A switch primarily operates at the Data Link layer (Layer 2), but multi-layer switches can also perform functions at the Network layer (Layer 3).

Analysis and Detail

1. Function of a Switch: A switch is used to connect devices within the same network, enabling communication by forwarding data packets based on MAC addresses.
2. OSI Model Layer: Since switches primarily work with MAC addresses and create a single network segment, they function at the Data Link Layer (Layer 2).

Verify and Summarize

The functions and operations of switches align them with the Data Link Layer of the OSI model. Some advanced switches may operate at Layer 3 as well.

Final Answer

Switch is a Device of Data Link Layer of OSI Model.
