"question": "请简述 TCP 三次握手的过程及其作用。",
|

|
|
"answer": "TCP 三次握手过程：1) 客户端发送 SYN 报文，seq=x；2) 服务器回复 SYN+ACK 报文，seq=y, ack=x+1；3) 客户端发送 ACK 报文，seq=x+1, ack=y+1。三次握手的目的是确认双方的发送和接收能力正常，同步初始序列号。",

|
|
"explanation": "三次握手是 TCP 建立连接的核心机制。第一次握手：客户端发送 SYN；第二次握手：服务器回复 SYN+ACK；第三次握手：客户端确认 ACK。这确保了双方都能发送和接收数据。",
