What is the difference between wireless and wired Internet access, and how much does it cost?

The most commonly used cable is broadband now, the speed is very fast, the cost is different for each plot, I here (Jiangyin, Jiangsu) 2M broadband monthly package is 70 yuan;

There are two types of wireless Internet access:

1) One is through the wireless LAN, now many high-grade coffee bars, communities have wireless LAN, as long as you have a wireless network card, you can access the Internet wirelessly within the scope of the wireless LAN, if the wireless LAN network is broadband (now it is generally), the speed of wireless Internet access is also very fast, generally free;

2) The other is the real wireless Internet access, put your notebook with a wireless network card, now there are two kinds of mobile and Unicom, the speed of Unicom is relatively fast, as long as there is a mobile phone signal range coverage of the place can be wireless free Internet access, the disadvantage is that the speed is relatively slow, Unicom is currently the fastest network speed is 153k s, not suitable for **, can only chat or browse the web! What I am using now is Unicom's wireless network card, using national roaming, 100 yuan for 60 hours a month; If you roam in the province, 100 yuan for 120 hours a month; City roaming is cheaper, the specific amount is not clear, I think at least generally have to do a provincial roaming, otherwise it will not be able to reflect the advantages of wireless!

The difference is between wired and wireless, and the cost is wireless over wired.

1. Wired network: a computer network connected by coaxial cable, twisted pair and optical fiber.

3. Coaxial cable network is a common way to connect the network. It is more economical, the installation is more convenient, the transmission rate and anti-interference ability are average, and the transmission distance is shorter. Twisted pair network is currently the most common way to connect to the network.

It is inexpensive and easy to install, but it is susceptible to interference, has a lower transmission rate, and has a shorter transmission distance than coaxial cables. Optical fiber, short for optical fiber, is a light conduction tool that uses the principle of total reflection of light in fibers made of glass or plastic. The tiny fiber is encapsulated in a plastic sheath, allowing it to bend without breaking.

Typically, a transmitter at one end of the fiber uses a lightemitting diode (LED) or a laser beam to deliver light pulses to the fiber, and a receiver at the other end of the fiber uses a photosensitive element to detect the pulses. In everyday life, optical fibers are used for long-distance information transmission because the conduction loss of light in optical fibers is much lower than that of electricity in wires.

5. Wireless network: mainly using air as the transmission medium, relying on electromagnetic waves and infrared rays as carriers to transmit data, although the networking mode is convenient and flexible, but due to the high cost of wireless networking, it is not very popular.

<> The differences between wired and wireless networks are mainly in:

1. Different equipment: the wired network needs to be connected with network cables between the devices, while the wireless network does not need to;

2. The anti-interference ability is different: the anti-interference ability of the network is stronger, and it is not easy to be accompanied by electromagnetic interference compared with the wireless network;

3. Stability is different: The network speed of wired networks is more stable than that of wireless networks.

Nowadays, online shopping, online dating, online learning, etc. are very common, and they all need to use the Internet. Because of the connection to the Internet, our shopping and life have become more convenient. What is the difference between a wired network and a wireless network?

From the point of view of connection mode, the wired network needs to use the network rental answer line, which can generally only be used at a fixed point, while the wireless network does not need to use the network cable, and can be used directly by searching for the connection to wifi, which can be used flexibly within a certain range; From the perspective of anti-interference, the wired network has strong stability and anti-interference ability, while the wireless network has weak anti-interference and often drops the network.

What should I pay attention to when installing a network cable.

1. Before installing the network cable, you need to choose the right operator, each operator's network speed, ** and cost are different, you can choose according to your actual needs.

2. When choosing a network, you need to understand the details in detail, and only one computer can be used in some contracts. If you have a Zen type or you have multiple computer needs, you should pay attention to this when purchasing.

3. Before installing the network cable, it is necessary to choose a high-quality and flexible network cable, so that it is not easy to break the network cable and be damaged by mice.

4. Whether it is for home use or office use, the length of the network cable should not be too long, because the network cable that is too long is not only difficult to store and organize, but also easy to damage the network cable, and will also leave certain potential safety hazards. When pulling the cord, try to go as high as possible and on the wall, preferably out of reach of children.

5. When pulling the cable, it is necessary to clean up the debris in the room, and take certain protective measures for the network cable, and do not pull the network cable vigorously, so as not to tear the network cable and step on it.

One wants a line, and the other doesn't want a line.

The amount of wiring and rerouting of wired network is large, and the line is easy to be damaged; Sites in the network are not movable. Especially when the remote sites that are several kilometers to tens of kilometers apart are connected to the network, or when the two local area networks of such a distance are connected, when the first line is used as the transmission medium, there is low rate, high bit error rate and poor line reliability.

Wired Internet access is a general term for Internet access through wired lines, which can be accessed through optical fibers, ** lines, etc. Wireless Internet access is not to line, through radio transmission to the Internet, there are currently 3G network cards, WLAN and other ways to access the Internet, as for what computer does not matter, equipped with related hardware can be connected to the Internet.

Stability: The performance and stability of the Internet through wireless connection can not catch up with the effect of using network cable connection, because the transmission range of wireless signals is limited, and wireless signals will be blocked by obstacles, and can only be used in a small area. Compared with wired LANs, wireless LANs have low development and operating costs and short time.
