  A dock is a dock used to expand the capabilities of a laptop. Through ports and slots, it can connect a variety of external devices, such as drives, large-screen monitors, keyboards, printers, scanners, and more.
  It can make up for the defects of thin and light laptops with fewer accessories, and this design allows users to enjoy the convenience and comfort of a desktop computer in the office, while playing with the portability of a laptop when working on the move.
  At present, there are two ports to 12 ports and other interfaces on the market, the number of docking dock, these ports cover charging, audio, USB, HDM I, SD card, network port and other functions, and multiple ports can be used at the same time, without affecting each other.
docking station
  1. USB3.0: Expand peripherals
  It mainly realizes the need to transfer data between the U disk and the mobile hard disk, and connects the mouse, keyboard, and MacBook mouse key.
  2. USB2.0: Data transmission
  The maximum transfer rate of USB2.0 is 480Mbps, or 60MB/s. However, in most cases, the maximum actual transfer speed of usb2.0 is only 30MB/s.
  3. Type-C interface
  Support mobile phone, hard disk, ∪ disk and other data transmission, now the speed of USB 3.1Gen2 has reached 10Gbps, the design standard can also meet the video and data transmission.
  Applicable to Apple Macbook, Huawei Mate Book, Xiaomi Notebook, Huawei P40, Mate30, Samsung S20, S10 series mobile phones.
  It should be noted that USB3.1 Gen1 is USB 3.0, and USB3.1 Gen2 is the real USB3.1.
  4, USB-A: Connect the keyboard and mouse
  The USB-A port is also used to connect the keyboard and mouse, because the keyboard and mouse have low performance requirements for the interface.
  Therefore, regarding the connection of keys and mice, you only need to pay attention to the number of interfaces when purchasing, and you do not need to worry about performance problems.
  5, lightning interface
  The interface uses Thunderbolt technology and meets both PCI Express and DisplayPort communication protocols.
  PCI Express is used for data transfer, DisplayPort (aka DP interface) ultra HD video and up to eight channel audio.
  Thunder 3 interface, 40Gbps theoretical transmission rate. The host port, cable, and terminal equipment meet lightning specifications to achieve the best transmission performance.
  Use more in the notebook, the notebook with the interface is better for docking compatibility! However, products that support the Thunder 3 are currently very expensive.
  6, HDMl: external large screen
  At present, the mainstream is HDMI1.2, HDMI1.4, HDMI2.0 versions, different interfaces support different resolution, color depth, refresh rate.
  HDMI interface is a kind of interface used to transmit image and sound signals, which is more common in smart TVS, set-top boxes, projectors and other devices, and its interface is inverted trapezoid. In business, the use of projector/display, for meetings, PPT and other scenes, need to be matched with the corresponding HDMI cable to achieve screen projection.
  HDMI interface was proposed in 2002, with the development of the industry, HDMI 2.1 standard has been able to support 4K@120Hz and 8K@60Hz, support high dynamic range imaging (HDR), can be optimized for the scene or frame number, backward compatible with HDMI 2.0, HDMI 1.4. And most importantly, it's both video and audio.
  7. VGA port
  Can be connected to projectors, VGA supports the highest resolution: 1080P/60Hz.
  VGA ports are also called D-Sub ports. VGA uses an analog protocol. VGA interface adopts 15-pin pin structure, which transmits components, synchronization and other signals, and is the interface used by many old graphics cards, notebooks and projectors.
  Due to a series of problems such as wire and signal interference, VGA can generally only reach 1080p resolution when used, the font is easy to be virtual at high resolution, and the image has a tailing phenomenon if the signal line is long.
  8. DP port
  It is mainly equipped with the game book, which has a larger bandwidth, and it is necessary to distinguish that some games are equipped with mini DP interface, and the purchase of the cable requires mini DP to DP standard interface.
  DP interface (DisplayPort) is an image display interface that can support not only full HD display resolution (1920×1080), but also 4k resolution (3840×2160), and the latest 8k resolution (7680×4320).
  9. SD/TF card slot
  Connect mobile phone card, camera card, big card, small card plug and play, to solve the MacBook/ Ultrabook card slot reading problem.
  According to the appearance, SD cards can be roughly divided into: SD card, mini SD card, Micro SD card (formerly known as TF card) these three.
  SD card: A new generation memory device based on semiconductor flash memory. Suitable for cameras, camcorders, e-books, MP3, AV equipment, etc.
  TF card: alias microSD, mini version of SD card. A tiny flash memory card. Due to the advantages of small size and large capacity, it is suitable for GPS devices, music players, flash memory disks, mobile phones and other compact storage devices.
  10, 3.5mm audio interface
  3.5mm standard audio port ADAPTS to most audio devices on the market, supports audio input and output at the same time, and supports easy connection of headphones/microphones/speakers.
  11. Ethernet port: Connect a network cable
  Connected wired network, mainly for the stable network to provide protection, there are 100 megabits and gigabit on the market, try to choose gigabit, transmission rate 1Gbps, theoretical download speed 125M/s, this point needless to say, as long as the choice of network port, basically it.
