What is Cisco? 

Cisco, widely known as Cisco Systems, is a US-based multinational technology giant based in San Jose, California. Cisco was founded in 1984 by Leonard Bosack and Sandy Lerner and is the world's largest provider of networking solutions. The company is highly regarded for its inventive solutions spanning networking, security, collaboration, and Cloud Computing.
 

What are Cisco Switches? 

Cisco Switches are networking devices that use packet switching to accept, process, and forward data to their designated destination. Unlike hubs, which broadcast data to all devices connected to them, switches create a direct connection between the source and destination devices. This ensures more efficient data transfer and better network performance.
