What is a network switch?

The network switch is an Ethernet-based LAN device that deals with reading and receiving the data packets and directs them towards LAN which helps with deciding which output ports should be used to transmit the data packets. The switches also help with centralizing the communication among the devices that are connected to one LAN. Moreover, network switches help with connecting the devices through the electronic tunnel, without being collided with traffic coming from any other source.  As most of the networking components now use switches as the bridges to send and receive packets of data rather than providing interrupted hardware units. Also, with the development of virtual LAN or VLAN, the networking switches have evolved, which help with waiving the traffic that helps with moving data packets between nodes and LAN.

How does a network switch work?

For the switch to work, the device is connected to the switch, which helps the switch to note its media access control (MAC) address, which is a code that is embedded into the network interface card (NIC) which connects to an Ethernet cable that further connects with the switch. The MAC address helps the switches with identifying the outgoing packets from the devices and the destinations for the incoming packets. Once the MAC address determines the physical device withstands the Layer 3, the IP layer can be linked to a device and changed or upgraded, whenever needed. Moreover, the packet is sent to another device, then enters the switch, and then the switch reads its header to decide what needs to be done with it. if the destination matches the address, the packet is sent through the ports that lead toward the destination devices. Moreover, to minimize the chances for interruptions between the network traffic going to and from between the connected device and switch. Also, some switches offer full-duplex functionality in packets which provides the connected device with the full bandwidth of the switch connection. Hence, the switches can operate at both Layer 2 and Layer 3 which supports LAN (VLAN).

Types of network switches

There are different types of network switches that are compatible with different systems. there is a wide variety of switches available on the market including;

  • Fixed-Configuration Switches are one of the most economical options and are considered the best fit for small businesses or systems that have relatively average workloads. However, they are not scalable as they have limited ports.
  • Unmanaged Switches are variations of the fixed-configuration switch. They offer basic connectivity by simply plugging in the switch in the device.
  • Smart Switches offer more controls and customization. They come with management features ensuring enhanced security. These switches are best for larger networks as they are more scalable and provide better security.
  • Modular switches are considered the best fit where cloud storage is concerned as these switches help with adapting to the changes swiftly. These switches can be used for firewalls, network connectivity, and analysis. Also, these switches have different interfaces but they are comparatively more expensive compared to other switches.
