The most widely used devices used in computer networks are switches. But what does this widely used device do and what does it do? What is the function of a switch in a network? We will review all the mentioned items in this article.
Suppose you are going to set up a computer network. A computer has a port or network card and a place to connect to another system. What if you have several computers in your company or complex that are supposed to communicate with each other? You can communicate with only one other computer from one system. To communicate with several systems, it is necessary to install several network cards on each one so that they can communicate with each other. A wiser way is to use a small hardware device called a switch. A switch is a device to which a network cable is pulled from each system and when information is sent from a computer in the network, this device manages and sends the message to the main destination.
switch works in the second layer of the network. This device receives packaged information and data and sends the received packets to the destination and output port through the ports or the same positions it has. This will manage the network and connect all the nodes together. Do not forget that these network equipment are very smart and have a good understanding of sending data to the destination.
- The first and most important advantage of using it is connecting and connecting systems. You can connect a large number of users using it.
- What if there was no switch, and every device sent its information over the network? So, this device prevents traffic and speed drop in data transmission.
- The speed of information transfer in local networks increases.
- The switch controls the amount of network usage.
These switch models offer a fixed configuration and a fixed number of ports and are usually not upgradeable, which makes them less expensive overall in the commercial market. This model of fixed configuration switches includes unmanaged switches, smart switches and managed switches.
A modular model switch is a network switch that can be modified using replaceable units. Switches of this category give network operators more flexibility by changing their hardware. For example, you can increase the number of ports.
Stackable feature in switches gives the ability to directly connect several switches of the same model to increase capacity and use. It is interesting to know that when you connect several Stackable switches, only one IP address is assigned to the switches and it is known as a single switch in the network, and it is not even necessary to separate each of the devices. configure
In this type of switch, you can provide power to the devices with a network cable. PoE model switches provide the necessary power to start other devices through an Ethernet cable. If your network has distributed switching, it is possible that they are powered by PoE. In simple words, this device itself is powered from the main power source and with the help of PoE, and at the same time, these devices can provide power to other equipment connected to them, such as cameras and phones.
If you have used fiber optics instead of copper network cables, you should use fiber switches instead of regular switches to have an integrated fiber network. Normally, these switches are available in 5, 8, 12, 24, 32, 48 and 54 configurations in the market. The most important feature of optical fiber is that it can transmit information up to 120 km. While copper cables up to 100 meters cannot do this.
An ad hoc network occurs when two or more computers are connected through an intermediary node. First, ad hoc network does not need basic infrastructure such as routers or access points. Secondly, an ad hoc network is a temporary wireless network. In any place where there is no internet and people need to share their files, ad hoc network...

As you know, the server is a powerful and always-on computer that consists of a series of hardware and software resources and needs settings and maintenance. In fact, by implementing appropriate settings for the server, you can somehow architect its structure and make better use of its resources. In other words, using the server settings...
