What Are Switches? Explain The Concepts Of Layer-3 Switches?

1.	What Are Switches? Explain The Concepts Of Layer-3 Switches?
Answer» It is a device that connects multiple NETWORK segments. A switch analyzes the MAC address and then DETERMINES where to send the data. So a file addressed to a computer reaches only that computer through the use of a switch. The term ‘switch’ commonly refers to a Network bridge that PROCESSES and routes data at the Data LINK layer (layer 2) of the OSI model. SWITCHES that additionally process data at the Network Layer are often referred to as Layer 3 switches or Multilayer switches.
