Routing

Routing refers to the process of selecting paths in a network to send network traffic. The basics of routing include:
- Functionality: Routers determine the most appropriate path for data packets to reach their destinations. They use routing tables and algorithms to make these decisions.
- Protocols: Common routing protocols include OSPF (Open Shortest Path First), BGP (Border Gateway Protocol), and RIP (Routing Information Protocol). These protocols help routers communicate with each other to share information about the network topology.
Types of Routing:
- Static Routing: Routes are configured manually and do not change unless manually modified.
- Dynamic Routing: Routes are automatically adjusted based on current network conditions using protocols such as OSPF or BGP.
Switching
Switching, on the other hand, deals with the forwarding of data packets within the same network. Key points about switching include:
- Functionality: Switches operate at the data link layer (Layer 2) of the OSI model and use MAC addresses to forward data to the correct destination within a local network.
Types of Switching:
- Store and Forward: The switch reads the entire data packet before forwarding it to check for errors.
- Interrupt: The switch begins forwarding the data packet as soon as the destination address is processed, reducing latency.
