Understanding Routing: The Backbone of Network Communication

Routing is the process of directing data packets across networks, ensuring seamless communication between devices. A router plays a crucial role in connecting networks with different IDs, enabling efficient data transfer.

One key aspect of routing is Network Address Translation (NAT), which modifies source IP addresses to maintain security and streamline connectivity.

The two most prominent LAN technologies in use today are Ethernet (supports bandwidths of up to 100 Gbps equivalent to 100,000 Mbps) and WLAN.

Ethernet operates in the data link layer and the physical layer. Ethernet sublayers are related to the frame fields. The Ethernet MAC address is used and a MAC address table is built up in a switch. On the switch ports there is forwarding methods and port settings available on Layer 2. Also switch speeds come into the methods.
