Addressing
Physical addresses, which are frequently MAC addresses, are the type of addressing utilized in Ethernet. The address used to transmit frames is this one. Frames are created when packets are received from the network layer. This entails including details like the source and destination MAC addresses.
Switch Concepts and Configuration
A switch is a discrete piece of hardware that connects various computers to a single local area network (LAN). In the OSI model, network switches function at layer 2 (Data link layer).
- On the basis of MAC addresses, switches are utilized to forward the packets.
- The switch makes it possible for the device that has been addressed to receive the data.
- It checks the destination address before properly routing the packet.
- Full duplex operation is used.
- Since the source and destination are communicating directly, packet collision is minimal.
- It does not broadcast the message since its bandwidth is constrained.
