    Network Interface Card is a hardware that allows you connect your computer to the Internet. It is working in the link layer network component is connected to the LAN interface of the computer and the transmission medium, not only to achieve the physical and electrical connection between the LAN transmission medium matches, but also involves sending and receiving frame encapsulated frames and unpacking, MAC, encoding and decoding of data and data cache functions.
    Detailed features
    Card fitted with a processor and a memory (including RAM and ROM). Communication between the card and the LAN through a cable or twisted pair serial transmission manner. The communication between the card and the computer is on the computer's motherboard via I / O bus for parallel transmission manner. Thus, an important function of the card is to be a serial / parallel conversion. As the data rate and data rate on the bus on the computer network is not the same, so the card must be installed in the data cache memory chips.

    When you install the NIC card must be managed to install the device driver (such as intel 6235/6300/6250/6205/6200 wifi driver) in the operating system of the computer. This driver will later tell the card, what position will be transferred from the memory of a local area network over the data blocks stored. NIC also enables the Ethernet protocol.
    NIC is not independent autonomous unit, because the card itself without power but must use the power of the inserted computer and control the computer by.
    Identification Method Editor
    Here I will introduce a high quality card should have:

    (1) HASL
    Quality card board generally use spray tin plate, sheet of white card, while the poor yellow card.
    (2) the main control chip with high quality
    The main control chip on the card is the most important part, which often determines the performance of the card's advantages and disadvantages, so the quality of the card used in the main control chip should be mature products on the market. Many poor quality cards available in the market in order to reduce costs while using the older version of the main control chip, which undoubtedly played a card performance discount.

    (3) The majority of the use of SMT SMD components
    In addition to high-quality card electrolytic capacitors and high voltage ceramic capacitors, blocking most of the other containers of a more reliable and stable than the plug-in SMT SMD components. Most of the use of plug-in cards are of poor quality, which makes the card heat dissipation and stability are not good enough.

    (4) titanium gold cheat
    NIC selection of high quality titanium metal production Goldfinger, both increased their anti-jamming capability and reduces the interference to other devices while the finger at the nodes of the arc-shaped design. While the poor are mostly non-titanium gold card, the node is also a right angle turn, affect the performance of signal transmission.
    Next is several Network Drivers:
    network_driver_nngmh_wn_18.1.0.0_a08.exe This is Intel 825xx 10/100/1000 Ethernet Controller Driver This package provides the Intel 825xx 10/100/1000 Ethernet Controller Driver and is supported on Latitude, Optiplex and Precision models that are running the following Windows Operating Systems: XP, Vista, Windows 8 and Windows 7.
    n5110_network_driver_p7g35_wn_15.6.1_a03.exe Intel Centrino Wireless-N 1030 WiFi Driver Intel 6230/N1030/N1000 WiFi Driver for win7 64-bit This package provides the driver for the Intel Centrino Wireless-N 1030 WiFi Driver and is supported on the Queen 15 Intel running the following Windows operating systems: Windows 7 64bit.
    R302627.exe It is Wireless 1501/1503/1701 Half Mini Card Driver and is supported on Inspiron N4050/M4040/N5040/N5050/M5040 and Vostro Notebook 1440/1450/1540/1550 that are running the following Windows Operating Systems: Vista and Windows 7.
    NIC different classification:
    According to the working characteristics of the different tasks of the work object is specifically designed, more expensive, but very good performance. It is compatible with the card, the card is generally divided into ordinary workstations and servers dedicated NIC card. Dedicated server NIC is to adapt to more types of network services, there are differences in performance, be classified according to the following criteria: the bandwidth supported by the card can be divided into 10M card, 100M card, 10 / 100M adaptive network card, 1000M card a few species; depending on the card bus types, divided into ISA cards, EISA and PCI NIC card three categories, including ISA cards and PCI cards more frequently used. ISA bus card bandwidth is generally 10M, PCI bus card has a bandwidth from 10M to 1000M. Also 10M card, because the ISA bus is 16, while the PCI bus is 32, so the faster PCI card than ISA cards.
