Why would you activate more than one nic on a PC?

Activating more than one network interface card (NIC) on a PC can enhance network performance and redundancy. By using multiple NICs, users can achieve increased bandwidth through load balancing or failover capabilities, ensuring a continuous connection if one NIC fails. Additionally, multiple NICs can facilitate separate network segments, improving security and management of different types of traffic. This setup is particularly beneficial in server environments or for users with demanding networking needs.
