Difference between Hub and Layer 2 Switch

Difference between Hub and Layer 2 Switch

A Hub is a simple device that connects devices on a local area network (LAN). A hub receives a signal from one device and transmits it to all other devices on the LAN.
A layer 2 switch is more advanced than a hub. It can filter data packets based on their MAC addresses, which allows for better network performance and security. Switches also maintain a table of MAC addresses to direct traffic flow. Unlike hubs, switches do not broadcast every packet they receive to all ports. This makes them more efficient and faster than hubs.

What is Hub?

Hub is an online community where people with similar interests can connect and share information. The site includes forums, groups, and blogs where users can interact with each other. Hub also provides a search engine that helps users find information on the site. Hub is free to join, and anyone can create an account.

What is Layer 2 Switch?

A Layer 2 switch is a type of switch that forwards data at the Layer 2 level of the OSI model. Layer 2 switches work with MAC addresses, which are unique identifiers assigned to network devices. When a Layer 2 switch receives a frame, it uses the MAC address to determine where to forward the frame. Layer 2 switches can be used to create local area networks (LANs). A Layer 2 switch can also be used to connect multiple LANs together. Layer 2 switches are commonly used in enterprise networks.

Difference between Hub and Layer 2 Switch

Hubs and Layer 2 switches are both devices that are used to connect computers and other devices on a network. Hubs work by broadcasting all incoming data to all connected devices, while Layer 2 switches use MAC address filtering to forward data only to the intended destination. Hubs are typically slower and less expensive than switches, but they do not provide as much control over the traffic on the network. Switches are more versatile and can be used to create separate collision domains, which can improve network performance.


Hubs and layer 2 switches have different purposes in a network. A hub connects all devices on a single Ethernet segment while a layer 2 switch can connect multiple segments together. Layer 2 switches are better for larger networks because they can create more collision domains and improve performance.
