Indeed; a Computer Science course (not Computer Engineering) wouldn't bother with tcpdump. Flow control, error correction and 3 way ack algorithms would probably be described and discussed, but not in terms of the details of how they're applied in the TCP/IP stack - you're looking at them as abstract theory.

Computer Engineering probably would cover tcpdump, the TCP handshake (actually a 4 way handshake, with two steps combined into one packet), flow control in TCP and on network links, ECC as used in real networks etc.

as someone currently teaching a Computer Engineering "Network Engineering" course, you are right on all counts on what we cover. Also the time the Computer Science students took the class (due to a prof on sabbattical in their department) they struggled a bit because their classes tend not to cover low-level real world topics.

As an aside, the networking class is getting hard to teach. With DNS moving to be tunneled over https, with https being encrypted (instead of plaintext), and with HTTP3 being QUIC which is custom-protocol-tunnelled through UDP, the analyzing-tcpdump exercises are becoming more or less useless.
