Full Gigabit network? What exactly does a gigabit network mean

In general, the gigabit network is roughly composed like this: the gigabit switch constitutes the backbone part of the network, the gigabit network card is inserted on the server, and is connected to the switch through the wiring system, and many gigabit switches can be connected to the gigabit switch, and the gigabit switch is connected to the workstation. As mentioned above, equipment providers now generally provide users with overall gigabit network solutions, so the specific solution for building Gigabit Ethernet must be adapted to local conditions.

The key is the purchase and positioning of network equipment, which mainly includes network cards, switches, routers, firewalls, etc. Under normal circumstances, to build a real Gigabit Ethernet, at least these guys must be equipped, including the motherboard itself must support Gigabit network connection, Gigabit network card, Gigabit network cable, and real Gigabit support routing, switches, etc., so that they can really be called Gigabit network. Therefore, this article will describe the general scheme of building a gigabit network system from the purchase, characteristics and skills of these devices.

Here we mainly consider the gigabit network of the intranet or the original network upgrade, so the main consideration is the network card and switch. Of course, there is also the transmission medium, that is, the use of optical fiber and twisted pair, the gigabit network of the optical fiber transmission medium is defined by the IEEE standard, and the gigabit network of twisted pair is defined by the IEEE.

Gigabit network card, gigabit switch, the composition is called a thousand M network.

First of all, there are different types of gigabit routes, and they can be divided into three types: wireless gigabit, wired gigabit, and full gigabit.

1. Wireless gigabit refers to the road light exciter that exceeds 1000 megabytes after the number of router antennas and the bandwidth of each antenna are superimposed, for example, three antennas are composed of two 450 trillion antennas and one 1000 trillion antenna, and the bandwidth is equal to 1900 trillion after superposition.

It should be noted that if this router should be extra careful when buying, wireless gigabit is not the same as a wired port is also gigabit, so if there is a real need to have a wired port and wireless are gigabit routers, don't just look at the introduction on the webpage, be sure to check the port parameters.

2. Wired gigabit refers to a router with a gigabit port that has a gigabit port, not all wired gigabit have wireless functions, and some gigabit routes, such as some enterprise-level routers, have no wireless function, so buy this router according to your needs to choose whether to buy only wired or wireless.

3. Full gigabit refers to wireless network.

And the wired end is a gigabit router,This kind of router has nothing to explain,I can only say that you get what you pay for (personal experience),According to the budget and demand,Optimistic about the price、Pick a good function、Choose a good brand。

Recommendations for buying a gigabit router

The gigabit of the router can only be realized in the LAN state under the condition of the so-called gigabit, which is converted according to the unit, and the actual speed that can be achieved in the LAN is about 100MB seconds, which is the use of super five network cables.

In the case of a Gigabit network card (most devices can already be satisfied, if it is very old, it will not be possible).

If you use wireless, it will be limited by the transmitter and receiver, in fact, the device in my personal hand, the fastest signal is about 3MB (actual speed), and the signal can sometimes reach 8-10MB, and in most cases it is 7MB.

Therefore, it is recommended to consider the actual needs when buying a gigabit router, if you have a home NAS or other needs at home, and the broadband is more than 100M, you can buy all gigabit routers.

1.Define the difference.

Gigabit network means 1000mb s, Chinese called 1000 megabit seconds; The meaning of 100 megabit network is 100 mb s, which is called 100 megabit seconds in Chinese.

2.Displays the speed difference.

Gigabit Ethernet speed display is 1GB; The speed of 100 Gigabit is displayed as 100MB.

3.Network cable differences.

100 Gigabit network cable is Category 5 line and super Category 5 line; The gigabit network cable mainly refers to the six types of lines and super six types of cables.

4.The principle of application is different.

If all network equipment, network cables, and network cards are gigabit, then the entire LAN is gigabit; If there is a place of 100 Gigabits, then the transmission rate of the devices below this 100 Gigabit interface will be reduced to 100 Gigabits.

This means that the transmission rate can theoretically reach 1Gbps.

Gigabit Ethernet Yueda standard.

In 1995, the International Organization for Standardization was organized.

TIA EIA has issued the 1000Base-TX standard, which aims to use twisted pair cables in Gigabit Ethernet, which is intended to be used over Category 6 unshielded twisted pair cables.

UTP) at 1000Mbps. 1000BASE-TX is based on 4 pairs of twisted pairs and uses a transmission mechanism similar to the 100BASE-TX standard in Fast Ethernet, which is to transmit on two pairs of wires and receive on two pairs of wires.

The role of the network:

1. Easy to carry out distributed processing.

In the network, a relatively large problem or task can also be decomposed into several sub-problems or tasks, which can be distributed to different computers in the network for processing and calculation. This kind of distributed processing capability is very effective in the research and development of some major topics.

2. Comprehensive information services.

In today's information society, individuals, offices, libraries, businesses, and schools are generating and processing large amounts of information all the time. This information may be text, number, image, sound or even **, which can be collected, processed, and transmitted through the network. Therefore, integrated information services will become the basic service function of the network.

Summary. The difference is: double gigabit means that the WAN port + LAN port (1) is Gigabit, and the rest is 100 Gigabit.

All Gigabit is WAN port + all LAN ports are Gigabit.

Full gigabit can also be said to be double gigabit, including relationships.

The difference between dual gigabit and full gigabit routers.

The difference is: double gigabit means that the WAN port + LAN port (1) is Gigabit, and the rest is 100 Gigabit. All Gigabit is WAN port + all LAN ports are Gigabit. Full gigabit can also be said to be double gigabit, including relationships.

Full gigabit can be said to be double gigabit, but there is no difference.

There are three slight differences: 1. The supported frequencies are different 2. The supported rates are different 3. The range of wireless wifi is different.
