Address book network and hardware device platform

For example, in a computer: the network card is a hardware, and the broadband line connection of your home is called the network, if you can't access the Internet is caused by the network card failure or network failure, then it can be called:

It is the network card on your computer, the router switch, called the network equipment, and you can see for yourself if there is any problem.

You need to buy a network cable of about 1 yuan per meter, a crystal head, a switch with 24 ports (more than 300 pieces), if you need to buy a router for Internet access, it is about 100 yuan cheaper.

The IoT hardware consists of four modules: M2M; integration of industrialization and industrialization; Sensor network and RFID, the required hardware can be analyzed from the four links, such as sensors, RFID, embedded devices and communication equipment.

M2M is the transmission of data from one terminal to another, which means that the code is a machine-to-machine dialogue.

The integration of industrialization and industrialization is a high-level in-depth combination of informatization and industrialization, which refers to the industrialization driven by informatization, the promotion of informatization by industrialization, and the new road of industrialization; The core of the integration of industrialization and industrialization is the support of informatization and the pursuit of sustainable development mode.

A sensor network is defined as a wireless network composed of randomly distributed tiny nodes integrating sensors, data processing units, and communication units in a self-organizing manner.

Radio Frequency Identification (RFID) technology, also known as Radio Frequency Identification, is a communication technology that can identify specific targets through radio signals and read and write relevant data without establishing mechanical or optical contact between the identification system and the specific target.

The exchange group is late, the router, the hub collapses, and the plum and the cat.

Let's talk about switches and hubs first: they are used to connect machines in the LAN, and they are indispensable when building a LAN, in the simplest terms. If you want to connect several machines together and do resource sharing, use them. Both of them function the same, but the switch is faster than the hub.

Cat: English: modem Chinese:

Modem We must have it on the Internet, the function is to modulate and demodulate the erosion, is the device for signal conversion between the computer and the first line, composed of two parts: the modulator and the demodulator, the modulator is the digital signal of the computer (such as files, etc.) is modulated into the sound signal that can be transmitted on the first line, at the receiving end, the demodulator converts the sound signal into a digital signal that the computer can receive. Data communication between computers can be realized through a modem and a ** line. To put it bluntly, the Internet has to be able to pass the ** line, and it plays a transfer role.

The router: If you want to use one account for multiple machines, or when you use an IP to surf the Internet, you have to use our device. Here's how to join it:

The cat connects to the router, and the router connects to a switch or hub, which is then distributed to multiple machines through the switch or hub. (Of course, they are all connected with network cables).In this way, multiple machines can access the Internet with one account or IP.

Common network hardware includes: hubs, switches, routers, network cards, etc.

Network devices include network connected devices and network interconnect devices. A network-connected device is simply a medium through which the network is transmitted.

Network interconnection equipment includes: optical fiber, bridge, gateway, etc., and its purpose is almost the same as that of network connection equipment.

Commonly used network devices include: routers, switches, firewalls, intrusion detection (IPS), VPNs, and other devices. If I understand the network connection devices correctly, including:

Fiber optic transceivers, fiber optic modules, protocol converters, and other equipment. Network interconnection devices are a combination of the above two.

Cat Router Switch Hub.

Multi-party conference hardware equipment refers to the equipment that can be seen and purchased by yourself, which is generally placed in the computer room, and the first wire is connected to the equipment in the computer room, and the meeting can be held. The equipment belongs to you, you can use it however you want, call out, call in, call in, recording, computer control, etc., choose at will. The equipment is not expensive, such as the conference bridge of the well-known domestic brand "Haohuitong" is 2180 yuan, and the effect is absolutely high.

The content of the self-owned device meeting has good confidentiality and will not be leaked, and there is no need to even pay for taking the IP line. Compared with the platform, customers do not need to buy multi-party conference equipment by themselves, because this equipment belongs to the first conference platform company, the platform company will buy a large number of equipment, and then split it to the customer to use, and earn the first fee, so the fee is superimposed on the basis of the party and time, and the fee is more expensive. The equipment is a platform company, and the customer encounters low sound, intermittent sound, line failure, etc., and the customer is uncontrollable.

The content of the meeting cannot be confidential. In general, buying hardware ** conference equipment is equivalent to buying a house to live in. Using the software** conference platform is equivalent to renting a house.

It all depends on the needs of the customer. If there are fewer meetings, use the platform. There are many meetings, meetings are important, or to connect with the mixer, conference equipment, etc., it is necessary to establish its own multi-party hardware conference equipment.

Multi-party conference hardware is to set up a conference bridge by yourself, and then carry out post-maintenance by yourself, a one-time investment, but outbound participants still need a high long-distance cost, if you take IP, the voice effect can not be guaranteed. It is recommended to choose the platform class of **conference** business, no need to invest in hardware, and the ** meeting fee is very low, basically the same as the cost of you go to the conference bridge to call, our company uses Beijing Yuante, not bad, but also free support **meeting, if you need it, you can contact me to help you introduce it. Hope it helps.

Multi-party hardware conference equipment is still in China"It's good to get through"The equipment is more professional, large companies, electricity, finance, etc., will prefer multi-party hardware conference equipment, their meetings are relatively more focused on confidentiality and conference effects, they often have mixers, amplifiers, or ** conferences and other docking among them, they need their own control equipment. The best conference platform of the software, most of the users are some enterprises that do not have many meetings. If the meeting is very frequent, users will feel that the cost is too high, and they will choose multi-party hardware conference equipment, so that the equipment is their own, and the cost will be controlled, and their own equipment will not even need to go to IP.
