What is a network cable? What is broadband? And what is the relationship between the speed of the In

A network cable is the line that connects your computer to the network. For example, ordinary broadband actually uses the ** line, which is the same line as the ** line.

Broadband, from a general point of view, is the bandwidth that can meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept. At present, broadband for home users means that the transmission rate exceeds 2M, which can meet the needs of a large amount of information transmission such as voice and image.

Includes: Fiber, XDSL (ADSL, HDSL), Cable

ISDN (not strictly broadband).

It has nothing to do with the network cable, it has to do with the bandwidth that telecom allows you, for example, the network cable is the faucet, and the bandwidth is the water inside, and the amount of water flow is determined by telecommunications.

Network cables are classified according to their uses: straight-through cables, crossover cables, and reverse cables.

According to the material, it is divided into: twisted pair, coaxial cable, optical fiber.

Connecting two network devices or hosts requires different cables.

Bandwidth is the amount of data that can be transmitted per unit of time, and the unit is bps, which is the number of bits that can be transmitted per second.

In terms of network speed, there are still many aspects that affect it, such as the current data circulation in the network, the processing speed of computer RAM, and so on.

Broadband and network cable difference: different nature, broadband and network cable are two different properties of the object, they are essentially different, broadband is an abstract concept, indicating a dynamic information transmission rate, and network cable is a medium, is the carrier of information transmission;

The role of broadband is to transmit network information at different rates. The network cable is to make the devices connect with each other and improve the network information transmission efficiency between the devices;

There are different ways of existing, broadband exists in a virtual way, there is no physical one. A network cable is an actual cable that has a specific form.

The differences between broadband and network cable are as follows:First of all, let's introduce the network cable, which is an indispensable communication connection device in the LAN connection, which can be divided into three types: twisted pair, coaxial cable, and optical cable. Among them, twisted pair is a data transmission line composed of many insulated crossed wires, such as:

The common ** wire in our life is the twisted pair, which needs a crystal joint to connect with it.

Secondly, it is a dynamic and changing concept, there is no fixed standard, and it can meet the needs of people's senses when transmitting on the network.

In short, the starting point of their naming is completely different, the network cable is a physical existence, while the broadband is more inclined to practical applications. Broadband is mainly used in broadband communication, which relies on optical fiber communication network to provide users with visual, graphic, textual, communication and data interactive information.

There are three differences between <> network cable and broadband. It is a difference in nature, a difference in standards and a difference in classification. 1. First of all, the nature is different.

A network cable is indispensable for connecting to a local area network. Broadband is generally a medium that satisfies people's sensory needs. 2. The second is an Internet connection with a standard transmission rate of more than 256kbps.

3. The third situation is to classify different broadband networks, which can be divided into transmission networks, switching networks and catenary networks. The line generally used in network cables is twisted pair, which can be divided into shielded twisted pair and unshielded twisted pair.
