NIC is the short form of the Network Interface Card. Network Interface Card or simply Network Card is simply used to connect different types of devices into the network generally to access the internet or intranet.

NIC是Network Interface Card的縮寫。 網路介面卡或簡稱為網路卡，通常僅用於將不同型別的裝置連線到網路中以訪問Internet或Intranet。

什麼是NIC(網路介面卡)？ (

What Is NIC(Network Interface Card)?)

Network Interface Card explains itself in a pure way where A card which has a network internet interface to connect plugged devices into the network. This network also can be called the computer network which will generally be used to connect the internet. But incorporates or military the connection can be done to the intra-network or intranet without the internet. Network interface cards can have different networks, connections, port, cable types at different speeds.

網路介面卡以一種純粹的方式自我解釋，其中A卡具有網路Internet介面，可將插入的裝置連線到網路。 該網路也可以稱為計算機網路，通常用於連線Internet。 但是合併或軍事連線可以在沒有Internet的情況下建立到Intra-net或Intranet。 網路介面卡可以以不同的速度具有不同的網路，連線，埠，電纜型別。

網路介面卡網路型別 (Network Interface Card Network Types)

Network Interface Cards can have different network types to connect. Especially in the last decade a lot of different network types are created for connection.

網路介面卡可以具有不同的網路型別進行連線。 特別是在最近的十年中，建立了許多不同的網路型別用於連線。

• `Wireless Networks` are one of the most popular network types.
  “無線網路”是最流行的網路型別之一。
• `Bluetooth Networks` are a new type of network that simply uses Bluetooth protocol.
  藍芽網路是一種僅使用藍芽協議的新型網路。
• `Ethernet Networks` is another popular network type which uses CAT5 and CAT6 cables with Ethernet or IEEE 802.1X protocol.
  “乙太網網路”是另一種流行的網路型別，它使用具有乙太網或IEEE 802.1X協議的CAT5和CAT6電纜。
• `Fiber Networks` is a fast network that uses different protocols with fiber cables.
  “光纖網路”是一種通過光纖電纜使用不同協議的快速網路。
• `Copper Networks` are old-style networks which are used for Dial-up or similar connections
  “銅網路”是用於撥號或類似連線的老式網路
• `Cable Networks` are coaxial cable networks generally used with cable TV.
  “電纜網路”是通常與有線電視一起使用的同軸電纜網路。

網路介面卡連線型別 (Network Interface Card Connection Types)

Network Interface Cards can provide different network connections but they also need to connect to the system they will be used. Network Interface Cards can be connected to different types of devices like computers, laptops, Workstations, Servers, Tablets, Smart Phones, Embedded systems, TV, etc.

網路介面卡可以提供不同的網路連線，但它們也需要連線到將要使用的系統。 網路介面卡可以連線到不同型別的裝置，例如計算機，膝上型電腦，工作站，伺服器，平板電腦，智慧電話，嵌入式系統，電視等。

• `Integrated Connection` is a connection type where network interface cards simply integrated into the given system or mainboard.
  “整合連線”是一種連線型別，其中網路介面卡可以簡單地整合到給定的系統或主機板中。
• `PCI` and `PCIe` connection type will use mainboard PCI and PCIe slots to connect. They are generally provided by PC, Workstation, and Servers.
  “ PCI”和“ PCIe”連線型別將使用主機板的PCI和PCIe插槽進行連線。 它們通常由PC，工作站和伺服器提供。
• `FireWire` is generally used as an external connection type where the network interface card can be connected via FireWire port optionally using a cable.
  “ FireWire”通常用作外部連線型別，可以通過FireWire埠(可選)使用電纜連線網路介面卡。
• `USB` is the most popular external connection type which can be also used to connect network interface cards.
  USB是最流行的外部連線型別，也可以用於連線網路介面卡。

網路介面卡埠(Network Interface Card Ports)

A network interface is an interface to connect a specific network. Every network interface card provides at least a single interface to connect the network. The network interface type can be changed according to the network interface card, requirement, etc. This is also called port in most cases where wireless can be an exception because there is no port but an antenna. Let’s list some of the most popular of them.

網路介面是用於連線特定網路的介面。 每個網路介面卡至少提供一個介面來連線網路。 可以根據網路介面卡，要求等來更改網路介面型別。在大多數情況下，也可以將其稱為埠，在這種情況下，無線可能是一個例外，因為沒有埠，只有天線。 讓我們列出其中一些最受歡迎的。

• `RJ45` or Ethernet
  RJ45或乙太網
• `Phone Jack`
  電話傑克
• `Antenna`
  天線
• `Fiber option`
  光纖選項

網路介面卡電纜(Network Interface Card Cables)

Network interface cards connected to the network with some medium which is generally a cable. For the wireless networks, the medium is the air which is the alternative of the cable. The network interface cards use different cables according to the network type and network interface card port type.

網路介面卡通過某種通常是電纜的介質連線到網路。 對於無線網路，介質是空氣，是電纜的替代品。 網路介面卡根據網路型別和網路介面卡埠型別使用不同的電纜。

• `Fiber Cable`
  `光纜`
• `Copper Cable`
  銅電纜
• `Ethernet`,`CAT5`,`CAT6` cable
  乙太網，CAT5，CAT6電纜

網路介面卡LED(Network Interface Card LED)

Network Interface card provides some LED lights in order to provide quick information about the network card and network. This information is provided with different led colors which are described in the network card manual. But there are some general assumptions that are used by most of the network interface cards. These LEDs also called Network Interface Card Status LEDs.

網路介面卡提供了一些LED指示燈，以便提供有關網路卡和網路的快速資訊。 此資訊提供有不同的led顏色，這些顏色在網絡卡手冊中有描述。 但是，大多數網路介面卡都使用了一些一般性假設。 這些LED也稱為網路介面卡狀態LED。

• `Link Light` LED indicates whether the network connection exists between card and network.
  “連結指示燈” LED指示卡和網路之間是否存在網路連線。
• `Activity Light LED` indicates the network activity for transmission for frames. If the network is used this light will flick randomly when some data is transmitted or received.
  “活動指示燈LED”指示用於幀傳輸的網路活動。 如果使用網路，則在傳送或接收某些資料時，該指示燈將隨機閃爍。
• `Speed Light LED` simply indicates the connection speed to the network. This exists in network cards that provide multiple speed options.
  “速度指示燈LED”僅指示網路的連線速度。 在提供多種速度選項的網絡卡中存在此功能。

網路介面卡速度 (Network Interface Card Speeds)

Network interface cards can provide different speeds which are related to the connection type and card capability. In general following speeds are provided a different type of network interface card.
