Switches are key components of many business networks where you can easily connect multiple computers, printers, access points, phones, lights, etc. These switches allow you to send and receive information smooth and efficiently. In this article, we are going to be discussing Switch work.

How does switch work

Computers are connected to our switch we can concentrate on the work as every device has hardcoded physical address called MAC address where the computer sends the IP packet for another device. It encapsulates the pocket with frame and uses the destination of the MAC address of the device B and then sources it and sends it out. Later the frame arrives, and the IP packet is received, but it gets transverses the ethernet switch.

Unmanaged Switch

An unmanaged switch is a switch network which is designed to be plugged into work without any configuration. Unmanaged switches are used for basic connectivity in businesses, homes, etc. There are few more ports that are needed which allows it to work in your desk, lab or conference room.

Managed switch

Managed switches offer greater security and features which are much more flexible. This is because you can configure them to fit your network comfortably. This gives you a greater control which is efficient in controlling and better protecting your network, but it takes longer to improve the quality of services for websites who use this to access their network.

Network Switch vs a Hub

Some of the most basic networks are all connected with hubs. There is a limit to the number of users who can share this hub space network. The more devices added, the longer it will take the data o reach its destination, but a switch avoids these limitations.

Network switch work vs a router

A switch allows for different devices on network communication, and the router allows the different network to communicate. A router is connected networks to the internet, which allows multiple users to share a connection as the router acts as a dispatcher. This gives the best route for information to travel as the transmission is as efficient as possible.

 


Switching Process

  • The switch redirects the frame out through the right port; this is called redirecting. The frame enters the switch port and is checked by the memory which stores physical port and MAC address pairs to use it forward in the frame.
  • Remember switch allows you to look into IP packet and forwards the frame based on the destination of the MAC address.
  • MAC learning is a frame first arrives at the switch port which checks the source of MAC address within the frame and stores which can be stored in the next port number when received.
