中职计算机网络专业来此处补充知识😂，背诵太困难尝试看这个视频理解
讲得太清晰了，谢谢老师。
看了很多视频，看到你这个恍然大悟！很好的讲解，非常感谢！❤
受益良多
这么多年网络书籍白看了。老师你真厉害。
ppt做的真是大胆，配色极好。
老师讲的好的要爆炸。我用英语学习学的挣挣扎扎的，Cisco packet tracer也没法理解直到我在TH-cam发现了这些宝藏视频。老师太棒了！ 完美！视频全收了！目前学到第四讲，视频好的看着都要流泪了！！！！IEEE-48个赞！
10:13 IP address
10:16 2 parts of an IP address
10:22 网络编号
10:26 主机编号
10:35 mind soup
11:08 从网络体系结构角度看IP和MAC
12:07 12:16 IP address is in the head of the IP数据报文 in the network layer 12:19 Mac address位于data-linke layer首部
12:23 demo - 数据报转发过程中IP与MAC地址的变化情况 12:32 由三个网络两个routers两台主机形成的还有TCP/IP体系结构的小型互联网 12:41 每个主机只有一个网络接口，每个router有两个网络接口
14:16 in data-link layer:
18:01每个过程的第二步都需要找出IP对应的MAC address
18:16 ARP protocol
18:51 C is going to send data to A
19:16 RP protocol rationale
23:21 NOTE: ARP can be only used in one network
23:38 simulation
老师讲课时，也放背景音乐？
Pretty good！
妙啊 讲得真好
请问，可以分享PPT吗？谢谢
背景音乐太吵了
0:33 *MAC address*
1:04 question: *How do the machines, A,B,D,E, knows the frame is sent from machine C to machine A* how do they decide to accept the incoming frame or not
1:21
1:51 format of MAC address
2:17 MAC address aka. *Hardware address* or physical address
2:21 NOTE! even though it is called physical address, it does not refer to the address defined in the physical layer
2:29 the MAC address *belongs to the data-link layer*
3:06 standard representation of MAC address
3:30 representation in Linux, Mac
6:48 单播 example: C -> A
7:26 C send broadcast frame
7:59 C发送多播帧给多播地址
廣播的數據 如果ip mac 不匹配可選擇不丟掉嗎？
太难了，难😁
这个很简单了，通信原理才难点
很好！
