WebSep 19, 2024 · It’s important to know bandwidth doesn’t actually increase the speed of a network, it just appears to make the network faster. You can increase a network’s bandwidth all you want, but all you’ll end up doing is increasing the amount of data that can be sent at one time, not increasing the transmission speed of said data. WebA network switch operates on the data-link layer, or Layer 2, of the Open Systems Interconnection ( OSI) model. In a local area network ( LAN) using Ethernet, a network switch determines where to send each incoming message frame by looking at the media access control ( MAC) address.
