What is Cisco Switches/Routers?

Cisco switches and routers are networking devices that direct data traffic across networks. Switches operate at Layer 2 (Data Link Layer) of the OSI model, forwarding data packets between devices on the same network. Routers operate at Layer 3 (Network Layer), forwarding data packets between different networks, enabling communication across the internet. They are commonly used in enterprise networks, data centers, and internet service provider (ISP) infrastructures to provide connectivity, security, and network management capabilities.
