What is the network equipment?
In general, network equipment can be divided into active and passive equipment. Based on this, there are the specializations of network operator and network operator, each of which has a specific task during the setup and maintenance of network equipment. All devices and equipment that are responsible for transmitting information from one point to another point in the network are called passive network equipment. Equipment such as network cable, network rack, duct, etc.
What are the types of network equipment?
All hardware equipment that you need to install and set up a computer network is called network equipment. Today, network equipment has become very important in all organizations; Because efficient and suitable computer networks should be created in every organization so that the maximum use of these systems can be taken. Therefore, familiarity with network equipment can help to set up a more practical and accurate network. To understand the importance of network equipment and its concept, it is better to provide a brief definition of network first of all. A network is a set of computers, hardware or software that are connected to each other to communicate between users. By using the network, all geographic restrictions can be removed for connecting users and hardware and software resources can be shared. used. In addition, by using the network, information can be transferred between users faster and more accurately. Also, communicating through the network will increase security.
این Disabled network equipment
The performance of passive equipment has no dependence on electricity and electrical power. Passive network equipment refers to a set of equipment that plays the role of an infrastructure tool for information transmission. In general, the equipment that does not need electricity is included in this category.
ار Coaxial cable
Coaxial cable is one of the important equipments for establishing the network, which are of the large type for the backbone of the network, and of the small type at shorter distances for Workstations are used.
ان Wireless Antone
When the distance between the transmitter and receiver waves exceeds a limit, the signal drops and the speed decreases. In such a time, using wireless antennas can eliminate this problem.
ایر Fiber optic cable
The optical fiber cable is one of the important cables used in establishing a network. This cable is used when the distance between the source and the destination is more than 100 meters and a lot of bandwidth is needed. In optical fibers, light propagates through the reflection between the interface of the core and the sheath. Among the light sources of these cables, we can refer to laser diodes or light emitting diodes.
Network
One of the problems you may face in establishing a network is the increase in the number of switches and routers. At such a time, you need a suitable place to install and maintain network equipment.
Network rack is used to maintain and protect switches and routers. Usually, the network racks are made of metal and using a glass derby. You can use a variety of standing or wall racks with appropriate dimensions according to your network needs.
Panel Panel
Patch panels are other types of passive equipment in the network, which are divided into modular and non-modular. Patch panels are generally used to organize the cables inside the network rack. The use of non-modular patch panels is usually recommended for audio transmission.
If you have a large network, it is better to use modular patch panels for more flexibility. In modular patch panels, you can have all kinds of ports next to each other. If a port has a problem, there is no need to completely replace the patch panel and you can replace only the desired keystone.
این Active network equipment
In response to the question of what is network equipment, we must also examine and introduce active network equipment. Unlike the passive type, active network equipment needs electricity and electrical power. These equipments are usually involved in directing, amplifying, or generating signals.
ما Switch
Using a switch in the network provides communication between several devices in the network. By using the switch, users can send information simultaneously. Actually, by using switches, it is possible to create communication between different nodes of a network.
ایر Axis Point
Access point is one of the other hardware required to set up the network. This tool is used to communicate between computers in a wireless network. In fact, the use of access points in wireless networks is similar to the use of switches in cable networks.
ایر Retrine
Using a router, it is possible to connect a network to other networks. Routers are used in LAN and WAN networks. You can find the router in different types and with different architectures and use the right model according to your needs.
م I have
The last type of active network equipment that we will explain the use of is the modem. Modem is an abbreviation of modulator and demodulator, which is an active hardware device that connects us to the Internet world. The role of the modem is to convert digital signals to analog and analog signals to digital. Modems are produced and supplied internally and externally and as cards in normal and ADSL types.
One of the uses of the modem is to send information across the network and it can easily transfer information such as photos, text, videos, etc. from one network to another on the Internet.
