Behind the scenes, this operating system uses buffers for storing the text values that are entered.

在幕后，该操作系统使用缓冲区来存储输入的文本值。

When a user clicks " login" , the text values are sent to a server, which executes code that checks if that username exists, and if it does, verifies the password matches.

当用户单击“登录”时，文本值被发送到服务器，服务器执行代码检查该用户名是否存在，如果存在，则验证密码是否匹配。
