Benefits of Layer 2 Switch

A Layer 2 switch is a networking device that forwards data at the data link layer (Layer 2) of the OSI model. It uses MAC addresses to forward data frames to the appropriate ports within the same LAN. There are several benefits of using a Layer 2 switch in a network:

• Reduced Network Congestion: By forwarding data frames only to the intended destination, a Layer 2 switch can reduce network congestion and improve overall network performance.
• Increased Security: A Layer 2 switch can be configured to limit broadcast traffic and control access to the network based on MAC addresses, which can increase security and help prevent unauthorized access.
• VLAN Support: Most Layer 2 switches support virtual LANs (VLANs), which allow for the creation of multiple logical networks on a single physical infrastructure. This can improve network segmentation and enhance security.
• Quality of Service (QoS): Layer 2 switches typically support Quality of Service (QoS) features that allow you to prioritize certain types of traffic, such as voice or video, to ensure that they are delivered with minimal delay and jitter.
