What is the difference between Hub and Switch?

One of the major differences between Hubs and Switches is the speed that each offers when transmitting data across the network. Hubs are used to transmit a single packet of data to different computers that are connected to them. Just a packet of data can enter the hub at a particular, and then the packet will be sent to all the computers that are connected to it. In the event that there are multiple packets to be sent, each packet will be sent one after the other.

On the other hand, switches allow data to be broadcast between two computers. This means you can't use switches to transmit data to more computers at a time, like hubs. Switches work by creating a breach between two computers so that they can easily send data across to each other. However, you can create more paths within the switch so that computers can transmit data with speed. Collisions usually occur in hubs, but less common in switches.

Hubs and switches are two terms that are used interchangeably regarding the network component that connects all the nodes in the network. Most people have not stopped referring to these devices like hubs rather than switches. The difference between the two types of devices is the overall speed so that they can broadcast data across the network.

Most devices can transmit information a lot faster compared to hubs. Hubs are simple apparatuses that accept a single data packet then send it out to all the computers that relate to it. This process often precedes a collision of data where a computer tries to send data to the hub while it’s broadcasting. Switches do not broadcast the information to all the computers in the network. To connect one computer to another, the internal functions of the switch creates a bridge between the two. This bridge makes it possible for computers to send data at full speed. Collisions do not occur on switches.
