Routers connect multiple networks together, while switches connect devices within a single network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.

• Routers determine the best path for data packets based on routing tables, whi...read more

A MAC address is a unique identifier assigned to network interfaces for communications on a network.

• MAC stands for Media Access Control

• MAC addresses are 48 bits long

• They are usually represented in hexadecimal format, like 00:1A:2B:3C:4D:5E

There are 5 types of IP classes: A, B, C, D, and E.

• Class A: Used for large networks with over 16 million hosts. Example: 10.0.0.0

• Class B: Used for medium-sized networks with up to 65,000 hosts. Example: 172.16.0.0

• Class C: Used for small networks with up to 254 hosts. Example: 192.168.0.0

• Class D: Reserved for multicast addresses. Example: 224.0.0.0

• Class E: Reserved for experimental use. Example: 240.0.0.0
