You need a network protocol that guarantees every byte arrives, in order, with no loss. Which socket type do you create, and what do you give up vs the alternative?
What is the correct order of TCP server calls before you can talk to a client, and what does each step do?
What does this client snippet do wrong?
```python
s = socket.create_connection(
(ip, 50000))
s.send("hello")
```
A peer sends exactly 1000 bytes in one send. Your TCP code does data = conn.recv(1024). Is data guaranteed to be all 1000 bytes?
In a TCP receive loop, how do you detect that the peer closed the connection?
```python
while data := conn.recv(1024):
...
```
Why wrap a socket in with socket.socket(...) as s: instead of just assigning it?
