/Network switches - What you should know

Switches are an essential part of computer networks, providing a way of connecting devices together to allow communication between them. A switch is a network device that connects devices on a local area network (LAN) to allow them to communicate with each other. Switches operate at the data link layer of the OSI model, which is the second layer of the seven-layer model. This layer is responsible for the reliable transfer of data between network devices.

Basic informations

Switches come in different types and configurations, with varying capabilities and performance characteristics. The most common types are:

  • Unmanaged Switches – these switches are the simplest type and are typically used in small networks. They provide basic connectivity between devices and cannot be configured.
  • Managed Switches – these devices offer more advanced features such as VLANs (Virtual Local Area Networks), QoS (Quality of Service) and port mirroring.
  • Layer 3 switches – these switches are also known as routing switches because they can route traffic between different subnets or VLANs. They are more expensive than other types of these devices, but are essential in larger networks.

Switches can be further classified based on their architecture, such as:

  • Modular Switches – these switches allow more ports or features to be added by adding modules to the switch.
  • Fixed Switches – urządzenia te są dostarczane z ustaloną liczbą portów i funkcji, których nie można zmienić ani uaktualnić.
  • Stackable Switches – these devices come with a fixed number of ports and features that cannot be changed or upgraded.

Switches use a variety of technologies to enable communication between devices, such as:

  • The most common technology used in switches is Ethernet. This is a set of standards for transmitting data over a LAN.
  • Spanning Tree Protocol (STP) is a protocol used in switches to prevent loops in the network. It works by disabling redundant links between switches, ensuring that there is only one active path between any two devices.
  • Virtual Local Area Networks (VLANs). VLANs enable the creation of logical networks within a physical network. This provides security and performance benefits by distributing traffic between different groups of devices.
