What is an integrated NIC?

Integrated network card integrated LAN, the integration of the network card to the motherboard from the beginning of the 1810 era, especially with the current ADSL of various broadband access mode of popularization, the demand ratio of network card has been increased. Therefore, the scheme of integrating the NIC into the motherboard has been widely used by the manufacturers of various sizes.

The network decoder chip (Ethernet Controller) integrated on the motherboard from 02 10M to later 100M. To the 1000M now. The gigabit network is already widespread. Integrated network card manufacturers: Realtek,marvell,intel,boardcom,via,3com can through the motherboard specifications, boxes, etc. to confirm their own network card brand model, download-driven. and the integration of the driver of the network card is often in the motherboard attached to the CD.

Today's motherboards are more than just integrated sound cards, and the NIC becomes an integral part of the motherboard (graphics cards are not universally integrated for special reasons). People on the sound card and network card performance requirements far less than the requirements of the video card. The integration of the network card to the motherboard from the beginning of the i810 era, especially with the current ADSL and a variety of broadband access to the popularity of the network card demand ratio has been increased, therefore, the network card integrated into the main board of the program gradually for the large and small manufacturers are widely used. Not only that, now the motherboard integrated network card is still full of tricks, the emergence of gigabit NIC and dual (dual network card) network card and other new technologies.

Advantage

1. Low cost 2. Easy to use 3. The integration is relatively high, has the high practicability, can satisfy the daily most application demand.

Disadvantage

1. Once the damage is more troublesome 2. Older or biased chips (such as Realtek 8201CL) drive more trouble 3. Performance is often not too good to meet a part of the needs of people.

Classification

According to the bus to divide

Can be divided into the following categories:

1, ISA interface network card

Due to the limitations of ISA bus, the network card of this kind of interface has been rare in the market. For now, the ISA interface's network card features a cheap price. But it has the characteristics of low transmission speed and installation trouble.

2, PCI Interface network card

Now the most widely used, but also the most popular network card. It has the characteristics of high cost performance, simple installation and so on.

3, USB Interface network card

Only recently appeared products, mainly to meet the lack of built-in network card notebook users. It is led by USB on the motherboard.

According to the transmission speed to divide

1, 10Mb network card

The maximum transfer rate is 10Mbps. A few years ago the popular network card, mainly applied to the general line topology, and later to solve the network collision problem, also appeared star topology (RJ-45) of the network card. This kind of network card mainly is the price is cheap, is suitable for the general household use.

2, 10/100MB Adaptive network card

The maximum transfer rate is 100Mbps. One of the most popular network adapters now. The so-called adaptive is to have automatic detection of network speed characteristics, if your current physical device is not able to transmit 100Mb, it will automatically drop to 10Mb.

3, 10/100/1000MB Adaptive network card

The maximum transfer rate is 1000Mbps. Also is now said that the Gigabit network card, can be based on the line and physical equipment to automatically detect the speed of the network.

According to the interface to divide

1, RJ-45

This is defined by IEEE, which stipulates that the network card using the RJ-45 interface should be connected with the RJ-45 Crystal Head, and the cable should use twisted pair.

2, AUI (10M network use)

This kind of network card mainly applies in the bus topology structure, the network cable must use the coaxial thick cable.

3, BNC (10M network use)

Also mainly used in bus topology, the network can only use coaxial thin cable.

4, FDDI

is mainly applied to optical fiber networks. We are relatively rare and not even seen. The network card of this kind of interface is connected more strictly.

According to the need for network cable to be divided

1, wired network card

Is that we usually use the ordinary network card, cable that need network cable meaning.

2, wireless network card

Mainly for special purposes and the application of the network card, it is the most important feature is not required network cable, because the network card is integrated with a receiving signal IC.

Now the wireless card technology has been very mature, some special functions of the Department has been vigorously promote the wireless network.
