 #### 进程之间的通信方式以及优缺点
 
 * 管道（PIPE）
-    * 有名管道：一种半双工的通信方式，它允许无亲缘关系进程间的通信
+    * 有名管道（命名管道）：一种先进先出的通信方式，它允许无亲缘关系进程间的通信
         * 优点：可以实现任意关系的进程间的通信
         * 缺点：
             1. 长期存于系统中，使用不当容易出错
             2. 缓冲区有限
-    * 无名管道：一种半双工的通信方式，只能在具有亲缘关系的进程间使用（父子进程）
+    * 无名管道（匿名管道）：一种单工先进先出的通信方式，只能在具有亲缘关系的进程间使用（父子进程）
         * 优点：简单方便
         * 缺点：
             1. 局限于单向通信

 #### Communication between processes and advantages and disadvantages
 
 * Pipeline (PIPE)
-    * Famous Pipeline: A half-duplex communication method that allows communication between unrelated processes
+    * Named pipes: A first-in-first-out communication method that allows communication between unrelated processes
         * Advantages: can achieve inter-process communication in any relationship
         * Disadvantages:
             1. Long-term storage in the system, improper use is prone to errors
             Limited buffer
-    * Unnamed pipe: a half-duplex communication method that can only be used between processes with parental relationships (parent-child processes)
+    * Anonymous pipes: A simplex first-in-first-out communication method that can only be used between processes with affinity (parent-child processes)
         * Advantages: simple and convenient
         * Disadvantages:
             Limited to one-way communication
