A set of computers that are connected together is called a network. Computer networks have different categories in terms of the type of connection and their application. But all of them have active and passive network equipment in common, which is a subset of electrical equipment. In this article, we describe this equipment. In general, it can be said that network tools and equipment have two general categories. Some of these tools need electricity to transfer data. and some other equipment that do not need electric current to perform their task. It refers to the first category of active equipment and to the second category of passive equipment. Active and passive network equipment each has unique features and functions and some components that we will introduce in the following.

Introducing components and functions of active network equipment

The task of active equipment is to produce, guide, orient, reproduce electric markers (signals). Then these bookmarks are transferred using passive equipment in the network system. Types of this equipment include the following.

• Switches that are required to establish communication between various systems and components.
• Hubs are another active network equipment. which act like a switch. But in terms of the type of technology used and the speed of operation, they are different from switches.
• The router is also required to connect different types of network to each other.
• If the network can be connected to the Internet by a router, if there is a modem in the network.
• Most internet services and services, such as file sharing services, etc., are provided through servers in the network.
• Sending and receiving data is done by the network card.
• Security issues should be considered in both active and passive network equipment. Firewalls are responsible for establishing security in the network. And they should prevent non-standard data types from passing through the network.
• Active network equipment includes some other security items such as detection of threats by IDS and destroying and denying access to those threats by IPS.

But the introduction of passive (inactive) network equipment

The passive equipment of the network is responsible for receiving the bookmarks sent by the active equipment and moving them around in the network. This tool has been called the backbone of the network. This equipment also has different components that we will refer to in the following article on active and passive network equipment.

• Different cables and sockets that play the most important role in the network. Because it is through this tool that different components of active equipment are connected to each other.
• Patch panels are parts that are used to manage and organize the network as best as possible.
• In the first case, the types of sockets were mentioned, one of them is the wall socket that allows people to access the network.
• Considering that there are many components of active and passive network equipment, especially in the passive part, you should think of a way to establish order between them. The racks collect all the devices in a certain order in one place and become a good protection for them. Also, with racks, you can use a variety of devices more easily.
• Some tools and various other equipment such as a device for connecting sockets to cables etc. are available in passive network equipment.

To create a network, only active and passive network equipment is not enough. But there must be people who can work with this equipment to create a network. People who know how to work with active equipment, which can be said to be related to the software part of the network, are called active network workers. And on the other hand, a person who performs the task of installing cables and other hardware components of the network well is referred to as a psio worker. They provide a complete set of active and passive network service equipment. Each of these services is unique. In the following, we introduce their services.

Introducing the types of services offered by the inactive sector.

• Drawing a network map and its design
• Wiring
• Telephone wiring and switchboard setup
• UPS wiring
• Network trunking and ducting
• Setting up keystones and required types of sockets
• Setting up servers and racks
• Setting up a CCTV camera under the direct supervision of the network
• Setting up sensors and tools that create intelligent capabilities to monitor the network
• Setting up all kinds of information systems such as announcing and extinguishing fire, which should be created for important parts such as the server location.
• Setting up some equipment such as router, server or switch

As we said before, active and passive network equipment are each providing services separately. In the following, we will get acquainted with the services of the active part of the network.

What are the active network services?

As mentioned, passive services make up the network infrastructure. But after this is done, active network services will start working, which include the following.

• Performing various settings and configurations of routers, switches, modems, access points and firewalls, which are actually active network equipment.
• Setting up various client and server operating systems such as Windows Server
• Activating all kinds of programs that are necessary for the network, including all kinds of IQ servers and all kinds of anti-virus
• Configuring and applying various settings related to users

We hope that in this article we have been able to provide you with useful information about active and passive network equipment.
