键盘和鼠标
相机和智能手机
进化：
继USB 2.0之后，出现了几个较新的版本：
USB 3.0（超高速USB）：2008年推出，最高速度可达5 Gbps。
USB 3.1和USB 3.2：进一步增强功能，提高速度并改善电源传输。
USB4:于2019年推出，结合数据和显示协议以提高性能。
尽管有了新的标准，但USB 2.0仍因其兼容性和足够的速度而被广泛使用。
USB 2.0（Universal Serial Bus 2.0）是第二代USB标准，相较于前代标准，在多个方面进行了改进和优化。其主要特点包括：
1.数据传输速率：USB 2.0 提供高达480 Mbps（即60 MB/s）的传输速度，远高于USB 1.1的12 Mbps。这个速度使得USB 2.0可以支持更多高带宽的设备。
2.兼容性：USB 2.0向下兼容USB 1.1，这意味着USB 2.0的设备可以与USB 1.1的接口兼容使用，但在此情况下会以较低的速度运行。
3.设备类型：USB 2.0支持多种设备的连接，包括键盘、鼠标、打印机、外部存储设备、数字相机等。
4.电源供给：USB 2.0提供的电源输出为5V，最大电流为500mA，这对于大多数外设来说已经足够。
5.即插即用：设备连接后，系统会自动识别并配置，无需重启计算机。
6.多种拓扑结构：USB 2.0支持星型和树型拓扑结构，允许多个设备通过集线器（Hub）连接。
7.封装和连接器类型：USB 2.0使用标准的USB A、B和Mini-USB等连接器，广泛应用于各种设备。
8.功耗管理：USB 2.0允许设备进入低功耗模式，以降低功耗，延长电池使用寿命（对于便携式设备如笔记本电脑等）。

USB 2.0 socket is an interface used to connect USB 2.0 devices, widely used in computers, chargers, peripheral devices, etc. It has the following characteristics:
1. Transfer speed: The maximum transfer speed of USB 2.0 is 480 Mbps, which is significantly higher than USB 1.1.
2. Compatibility: USB 2.0 and USB 1.1 are backward compatible and can be connected to old devices.
3. Plug types: Common plug types include standard A type, mini B type, mini B type, etc.
4. Power supply capability: USB 2.0 can provide up to 500 mA of current for devices, suitable for the charging needs of most portable devices.
USB 2.0， Also known as "high-speed USB", it is a universal serial bus (USB) connection standard introduced in April 2000. This version improves on the original USB 1.1 standard, providing faster data transfer rates, better power management, and greater compatibility with a range of devices.
The main features of USB 2.0 are:
Data transmission rate:
The maximum speed is 480 Mbps (high speed), significantly faster than USB 1.1's 12 Mbps (full speed).
Backward compatibility:
The USB 2.0 port can accept USB 1.1 devices without requiring any additional hardware.
connect:
Supports various types of connectors, including Type-A, Type-B, Mini USB, and Micro USB.
Power Supply:
Power the connected devices with a maximum current of 500mA (USB 3.0 can reach up to 900mA).
Multi device support:
Multiple devices can be connected through a single USB port using a hub.
Application:
USB 2.0 is used for various devices, such as:
printer
External hard drive
Flash drive
Keyboard and Mouse
Camera and smartphone
Evolution:
After USB 2.0, several newer versions have emerged:
USB 3.0 (Ultra High Speed USB): Launched in 2008, it can reach a maximum speed of 5 Gbps.
USB 3.1 and USB 3.2: Further enhance functionality, increase speed, and improve power transfer.
USB4: was launched in 2019, combining data and display protocols to improve performance.
Despite the new standards, USB 2.0 is still widely used due to its compatibility and sufficient speed.
USB 2.0 (Universal Serial Bus 2.0) is the second generation USB standard, which has been improved and optimized in multiple aspects compared to its predecessor. Its main features include:
1. Data transfer rate: USB 2.0 provides a transfer speed of up to 480 Mbps (i.e. 60 MB/s), much higher than USB 1.1's 12 Mbps. This speed allows USB 2.0 to support more high bandwidth devices.
2. Compatibility: USB 2.0 is backward compatible with USB 1.1, which means that USB 2.0 devices can be used with USB 1.1 interfaces, but in this case will run at a lower speed.
3. Device type: USB 2.0 supports the connection of multiple devices, including keyboards, mice, printers, external storage devices, digital cameras, etc.
4. Power supply: USB 2.0 provides a power output of 5V and a maximum current of 500mA, which is sufficient for most peripherals.
5. Plug and play: After the device is connected, the system will automatically recognize and configure it, without the need to restart the computer.
6. Multiple topologies: USB 2.0 supports star and tree topologies, allowing multiple devices to be connected through a hub.
7. Packaging and connector types: USB 2.0 uses standard USB A, B, and Mini USB connectors, which are widely used in various devices.
8. Power Management: USB 2.0 allows devices to enter low-power mode to reduce power consumption and extend battery life (for portable devices such as laptops, etc.).
