And, finally, unlike streams a zero byte read does not indicate that the message has been fully received.

最后，不像流那样，读取了零字节并不表明已经完全接收了消息。

If the number of ones in a byte is already odd, you will set its least significant bit to a zero.

如果一个字节中1的个数已经为奇数，那么就将它的最低位设置为零。

youdao

This is a zero byte message that tells the client that it's done with the "Hello" process and indicate that the server won't be asking the client for a certificate.

这是一个0字节的消息，它告诉客户端“hello”过程已经完成，也就意味着服务端将不验证客户端的证书。

And because there are a billion bytes accessible to us, that's-- essentially means well we can just call that byte number zero.

由于有十亿个字节的存储量供我们使用-,也就是说，我们有0号字节。
