elimination of broadcast traffic
network layer
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
The advantage of using a layer 3 switch is the speed at which it can establish a network connection.
The speed at which it establish a network connection.

Core layer switch forms the heart of the network. it interconnects all the subnetworks formed by distribution switches. It also has special modules such as IDPS. It has very high switching capacity when compared with normal (Access ) Switches. Distribution switch forms the intermediate layer between access and core switch.
When using network switches, each port on the switch is its own collision domain.
Switches are commonly known as "Layer 2 (Data Link Layer)".3550 Switches: These switches are working under Layer 2 (Data Link Layer) and it is forward the packets through MAC Address, but if we convert these type of switches into Routers it will function in Layer 3 (Network Layer) of OSI model as it's forward the packets based on the IP addresses.2950 Switches: These switches are working under Layer 2 (Data Link Layer) of OSI model only and it is forward the packets through MAC Address.
layer 3 layer 3 Switch/ Bridges / Hubs works at layer 2 as they utilizes MAC address to communicate. However i aggree above stated answer as there are some layer three switches that work at Layer3 i.e. Network Layer. Dhruv
network layer
a high grade layer 2 switch can be used to access local resources but will not be suffice to access the internet you would need a layer3 switch to access remote resources
