    英文回答：
    Mouse and Keyboard.
    Mouse and keyboard are two essential tools for computer users. They play important roles in facilitating our interaction with computers and enable us to perform various tasks efficiently. Let me explain their functions in detail.
    Firstly, the mouse, as a pointing device, allows us to move the cursor on the computer screen and select different items by clicking the buttons. For instance, when browsing the internet, we can use the mouse to click on links, scroll through webpages, and navigate between different tabs. The mouse also enables us to interact with graphical user interfaces, such as dragging and dropping files or icons. Without a mouse, it would be challenging to perform these actions accurately and quickly.
    Secondly, the keyboard is another indispensable input device. It allows us to type letters, n
umbers, and special characters to input text into various applications. For example, when writing an email, we can use the keyboard to type the content and press the enter key to send it. The keyboard also provides shortcut keys that allow us to execute specific commands or functions with a single press. This saves us time and effort, especially when working with software applications like Microsoft Word or Excel.
    In addition to their basic functions, both the mouse and keyboard have undergone advancements to enhance user experience. For instance, the mouse now often includes additional buttons, such as the scroll wheel and side buttons, which provide extra functionality. These buttons can be programmed to perform specific actions, like zooming in or out, or opening a new tab in a web browser. Similarly, keyboards now come with multimedia keys that allow us to control media playback, adjust volume, or launch specific applications with ease.
    In conclusion, the mouse and keyboard are indispensable tools for computer users. They enable us to navigate through digital interfaces, input text, and execute commands efficientl
y. Without them, our interaction with computers would be limited and less convenient.

    鼠标和键盘是计算机用户必不可少的工具。它们在促进我们与计算机的交互以及高效完成各种任务方面起着重要作用。让我详细解释一下它们的功能。
keyboard是什么意思啊    首先，鼠标作为一个指针设备，允许我们在计算机屏幕上移动光标，并通过点击按钮选择不同的项目。例如，在浏览互联网时，我们可以使用鼠标点击链接、滚动网页和在不同的标签之间导航。鼠标还使我们能够与图形用户界面进行交互，例如拖放文件或图标。没有鼠标，准确快速地执行这些操作将变得困难。
    其次，键盘是另一个不可或缺的输入设备。它允许我们输入字母、数字和特殊字符以在各种应用程序中输入文本。例如，在写时，我们可以使用键盘输入内容，并按回车键发送。键盘还提供了快捷键，可以通过单击一次执行特定的命令或功能。这节省了我们的时间和精力，特别是在使用Microsoft Word或Excel等软件应用程序时。
    除了它们的基本功能外，鼠标和键盘还经过了改进以提高用户体验。例如，鼠标现在通常包括额外的按钮，如滚轮和侧面按钮，提供额外的功能。这些按钮可以编程执行特定的操作，如放大或缩小，或在Web浏览器中打开一个新的标签。类似地，键盘现在配备了多媒体键，允许我们轻松控制媒体播放、调整音量或启动特定的应用程序。
    总之，鼠标和键盘是计算机用户必不可少的工具。它们使我们能够高效地浏览数字界面、输入文本和执行命令。没有它们，我们与计算机的交互将受到限制，变得不太方便。
