How many interfaces does the NIC have, how many RJ45 interfaces does the latest NIC have, and how ma

The RJ45 interface is usually used for data transmission, and is made of eight cores, and the most common application is the network card interface.

RJ45 is a type of various different joints (for example: RJ11 is also a type of joint, but it is used on **); There are two different ways to sort RJ45 heads and lines, one is orange-white, orange, green-white, blue, blue-white, green, brown-white, brown-white; the other is green-white, green, orange-white, blue, blue-white, orange, brown-white, brown-white; Therefore, there are two kinds of wires that use RJ45 connectors, namely: straight wires and interchangeable cables.

RJ-45 port is our most common port, it is our common twisted pair Ethernet port, because in fast Ethernet also mainly uses twisted pair as the transmission medium, so according to the different communication rates of the port, RJ-45 port can be divided into 10BASE-T network RJ-45 port and 100BASE-TX network RJ-45 port two categories. Among them, the RJ-45 port of the 10BASE-T network is usually identified as "ETH" in the router, and the RJ-45 port of the 100BASE-TX network is usually identified as "10 100BTX", which is mainly due to the fact that most of the fast Ethernet router products still use 10 100Mbps bandwidth adaptation. In fact, these two RJ-45 ports are exactly the same only in terms of the port itself, but the corresponding network circuit structure in the port is different, so it cannot be connected casually.

There is only one NIC for each card.

The BNC interface is the interface of a coaxial cable (thin cable), no.

The general network card only has one RJ45 interface, and I have seen four ports.

The BNC interface is our wired interface, and RJ-45 is now the ordinary network card interface!

Thank you for the trouble to adopt!

The network card is ultimately connected to the network, so there must be an interface through which the network cable can be connected to other computer network devices. Different network interfaces are suitable for different network types, and the common interfaces mainly include RJ-45 interface of Ethernet, BNC interface of fine coaxial cable, coarse coaxial electrical AUI interface, FDDI interface, ATM interface, etc. In addition, some network cards provide two or more types of interfaces in order to be suitable for a wider range of application environments, such as RJ-45, BNC interface or AUI interface at the same time.

1) RJ-45 interface.

This is the most common type of network card, and it is also the most widely used interface type network card, which is mainly due to the popularity of twisted pair Ethernet applications. Because this RJ-45 interface type of network card is used in the Ethernet with twisted pair as the transmission medium, its interface is similar to the common ** interface RJ-11, but RJ-45 is 8 cores, and the interface of ** wire is 4 cores. The NIC also comes with two status indicator lights, and the working status of the NIC can be preliminarily judged by the color of these two indicator lights.

2) BNC interface.

This interface NIC pair is used in Ethernet or token networks with thin coaxial cable as the transmission medium, and this interface type NIC is rare at present.

3) AUI interface.

This interface type of NIC pair is used in Ethernet or token networks with thick coaxial cable as the transmission medium, and this interface type of NIC is even rarer at present.

4) FDDI interface.

The network card of this interface is adapted to the FDDI (optical fiber distributed data interface) network, but the transmission medium it uses is optical fiber, so the interface of this FDDI interface network card is also an optical fiber interface. With the advent of Fast Ethernet, its speed superiority is gone.

5) ATM interface.

This interface type of NIC is used in ATM (asynchronous transfer mode) fiber (or twisted-pair) networks.

1.NIC interface? Nowadays, it is generally an integrated network card on the motherboard, and if it is a separate network card, then the PCI interface is used. But now, if it's not a professional field, very few people will use a separate network card.

2.If the landlord asks about the network cable interface, then it is RJ45

NIC interface: the port of network device connection: 1) RJ-45 interface; 2) BNC interface. 3) AUI interface. 4) FDDI interface.

5) ATM interface.

A network card is a piece of computer hardware used to connect your computer to the outside network. I know that there are 8129 and 8139 network cards, and now there is a kind of diskless network card that is generally 8139 network card, which can be used to boot the chip; The 8129 cannot be used on the boot chip, and for private customers, both can generally be used.

One of the key pieces of hardware in a network system is its adapter, commonly known as a network card. In a local area network, the network card plays an important role. The network card is used for the input and output of signals between computers.

The NIC has its own interrupt number (IRQ) and I 0 ditan. Network cards include ISA cards, EISA cards, and Ethernet cards used on Apple Mac machines. At present, 16-bit ISA network cards and 32-bit PCI network cards are widely used.

The network card has buffer memory in order to store data. Similar to sound cards, network cards usually come with their own drivers. When in use, the network card is inserted into the expansion slot of the computer.

There is an indicator light on the network card, which indicates whether it is working properly or not.

The transmission rate supported by the network card is different, some are 10 megabits per second, some are 100 megabits per second, and some can self-adapt to 10 megabits or 100 megabits.

A network card with a remote boot chip that can be used on diskless workstations. Diskless workstations without hard disks or floppy drives. Starting the computer through the network card can ensure the security of the system and avoid viruses. In addition, it is possible to reduce the cost.

In laptops, a smart PCMCIA card is used to exchange data with other computers. In high-speed networks, there are FDDI network cards used in optical fiber data distribution interfaces, and ATM network cards used in different card transmission modes. The network card used for the bus structure topology in the LAN is the network card of the BNC port, and the transmission medium is a section of 50 thin coaxial cables, and the two ends of a network segment need to be sealed with terminators to form a network loop.

Connect 2 wires, one core and one net.

It is impossible for BNC to achieve the clear effect of the webcam, because the modulation method used by BNC is the PAL system, which itself has the highest scan line and is about the clearest standard, and the webcam uses the standard, direct digital compression, how much pressure there is, no loss. Very good.

RJ11 is the first interface, generally there are two wires inside, RJ45 is our common 100M 1000M network interface, which is generally 8 with lines.

RJ11 is used to dial up the Internet with ** line. RJ45 is the twisted pair connector we usually see.

RJ45 is an integrated network card model. The Ethernet card interface is generally an independent network card

RJ45 is an interface that is commonly used for data transmission, and the most common application is a network card interface.
