计算机网络：数据链路层之差错控制、奇偶校验码、CRC循环冗余码、海明码

一、差错控制概括来说，传输中的差错都是由于噪声引起的。全局性 1.由于线路本身电气特性所产生的随机噪声(热噪声)，是信道固有的，随机存在的。解决办法:提高信噪比来减少或避免干扰。(对传感器下手) 局部性 ⒉.外界特定的短暂原因所造成的冲击噪声，是产生差错的主要原因。解决办法:通常利用编码技术...

计算机网络，CRC码计算生成

1.网络协议和Internet协议栈?网络协议概念：网络协议是计算机网络相互通信的对等层实体之间交换信息时必须遵守的规则或约定的集合。[网络协议是网络上所有设备（网络服务器、计算机及交换机、路由器、防火墙等）之间通信规则的集合，它规定了通信时信息必须采用的格式。TCP/IP协议、IPX/SPX协议。...
