绿联外围设备_什么是外围设备（外围设备的类型和列表）？
绿联外围设备
A Peripheral Device is a computer device or part which is connected to the computer with different connection types. A peripheral device is not a core device for a computer which means a computer can work without a peripheral device connected to it. Peripheral devices generally provide extra function and data input and output functionality to the computer systems.
Peripheral Device是通过不同的连接类型连接到计算机的计算机设备或部件。 外围设备不是计算机的核心设备，这意味着无需连接外围设备即可运行计算机。 外围设备通常向计算机系统提供额外的功能以及数据输入和输出功能。
什么不是外围设备？ (What Is Not Peripheral Device?)
Before starting to explain and list peripheral devices providing the non-peripheral devices will be more useful because there are some computer parts that are core and critical for a computer system which is not peripheral device and all other devices are categorized as peripheral devices.
在开始解释和列出外围设备之前，提供非外围设备将更为有用，因为有些计算机部件对于不是外围设备的计算机系统是至关重要的，并且对于所有非外围设备都被归类为外围设备。
CPU is not a peripheral device because a computer system can not work without a CPU.
CPU不是外围设备，因为没有CPU，计算机系统将无法工作。
Mainboard is not a peripheral device because the other core computer parts are connected and communicate over a mainboard.
Mainboard不是外围设备，因为其他核心计算机部件已通过主板连接并进行通信。
Memory is not a peripheral device because the data processed is stored inside memory and without a memory CPU and computer can not work.
Memory不是外围设备，因为处理的数据存储在内存中，并且没有内存，CPU和计算机无法工作。
Storage or Hard Disk Drive is not a peripheral device because the processes data is stored inside the storage or hard disk drive for long term usage.
Storage或Hard Disk Drive不是外围设备，因为过程数据存储在存储器或硬盘驱动器内部以供长期使用。
外围设备类型(内部和外部) (Peripheral Device Types (Internal and External))
Peripheral devices can be in different types according to their connection type to the system and data transmission direction. According to connection type peripheral devices a categorized as;
根据外围设备与系统的连接类型和数据传输方向，外围设备的类型可以不同。 根据连接类型将外围设备分类为：
Internal Peripheral Devices are generally located inside the computer system case and named internet because of their location. Here are some internal peripheral devices.

- External Hard Disk / USB Disk 外置硬盘/ USB磁盘
- Monitor (Except Laptops)显示器(笔记本电脑除外)
外围设备类型(输入，输出和复合) (Peripheral Device Types (Input, Output, and Composite))
Peripheral devices can be also categorized according to their data communication direction. They are called Input , Output and Composite .
外围设备也可以根据其数据通信方向进行分类。 它们分别称为Input ， Output和Composite 。
Input Peripheral Device is a device was used to input data into the computer system. Their main purpose is to get different types of input, digitalize it and forward it to the mainboard for processing.
Input Peripheral Device是用于将数据输入计算机系统的设备。 它们的主要目的是获取不同类型的输入，将其数字化并将其转发到主板进行处理。
- Keyboard 键盘
- Computer Mouse电脑鼠标
- Graphic Tablet图形输入板
- Touchscreen触摸屏
- Scanner扫描器
- Barcode Reader条码读取器
- Microphone麦克风
- Webcam摄像头
- Joystick游戏杆
- SD / Micros SD Card ReaderSD / Micros SD卡读卡器
- Digital Camera数码相机
Output Peripheral Devices mainly used to show and output information in different formats like Image, Video, Sound to the system user.
Output Peripheral Devices主要用于向系统用户显示和输出不同格式的信息，例如图像，视频，声音。
- Monitor / Computer Display 显示器/电脑显示器
- Printer打印机
- Projector投影机
- Speaker 扬声器
Composite Peripheral Devices can both input and output data. These types of devices generally used to transmit data and act as intermediate hop.
Composite Peripheral Devices可以输入和输出数据。 这些类型的设备通常用于传输数据并充当中间跃点。
- Floppy Disk Drive 软盘驱动器
- CD-ROM Drive / DVD DriveCD-ROM驱动器/ DVD驱动器
- Flash Drive随身碟
- Network Interface Card网络接口卡
- Modem调制解调器
外围设备连接类型(Peripheral Device Connection Types )
Peripheral devices are connected to the core computer systems via motherboard via different connection protocols and types. Every connection type has a different cable, plug, and protocol type. Below we will list some popular peripheral connection types.
外围设备通过主板通过不同的连接协议和类型连接到核心计算机系统。 每种连接类型都有不同的电缆，插头和协议类型。 下面我们将列出一些流行的外围连接类型。
USB is the most popular and easy connection type and protocol for peripheral devices. In today most of the peripheral devices connect with a USB connection because of its plug and play and multiple port availability.
USB是用于外围设备的最流行，最简单的连接类型和协议。 如今，大多数外围设备都通过USB连接进行连接，因为它具有即插即用功能和多个端口的可用性。
PCI is another popular connection type for peripheral devices. PCI generally used by the internal peripheral devices which require high data transmission bandwidth with reliability like Graphics Cards, Network Interface Cards, Ethernet Cards.
PCI是外围设备的另一种流行的连接类型。 通常由内部外围设备使用的PCI，这些外围设备需要高数据传输带宽并具有可靠性，例如图形卡，网络接口卡，以太网卡。
SATA is generally used by internet peripheral devices like storage devices, hard disk devices.
SATA通常由Internet外围设备(如存储设备，硬盘设备)使用。
HDMI is a popular next-generation connection where monitors, displays, and projections are connections.
HDMI是流行的下一代连接，其中显示器，显示器和投影是连接。
VGA is an old-style graphic display connection type which is the previous version of HDMI and used by monitors, displays, and projections.
VGA是一种老式的图形显示连接类型，它是HDMI的早期版本，并由监视器，显示器和投影仪使用。
