In general, network equipment today is divided into two categories: passive network equipment and active network equipment, which we will describe in the following.
Passive network equipment: Passive products that are used to install and set up network hardware are called passive network equipment. In general, we can not program this type of equipment, which is called passive network equipment, and Using this equipment, there is no need for electricity to operate it. The equipment that falls into this category includes duct, network rack, network connections, network connector, network patch cord, network cable.
Active Network Equipment: Active network equipment is the active equipment in the network that can program on the operating system of devices to execute commands and programs given by us. This equipment, unlike passive equipment, requires electricity to operate. The equipment that falls into this category includes modem, access point, router, network switch, network card.
LAN cables are produced in different types with special features and are divided into different categories based on the useful length of data transmission and the speed and quality of transmission. Many network cables can transmit data up to the defined area, and using more than the defined area will cause a signal drop, and each network cable has a certain speed and can transmit data to a certain size, so choosing a cable LAN with a certain speed is very important for network execution because information speed and information quality are directly related to each other.
Physical differences between telephone cable and network cable
Network cable and telephone cable are very close in appearance that these two cables are used all over the world. In terms of appearance, network cable is thicker than telephone cable. In LAN cable, eight wires are used to exchange information, but in telephone cable, four wires are used. LAN cable has different colors from different brands, but the color of the phone cable is gray. The connection ports of the network cable are larger than the telephone cable and information is transmitted to the device through these wires.
