Choose one or more of the following statements about this socket networking procedure running as the server (i. e. not the client):
1. Create network endpoint with socket()
2. Start listening for connections with listen()
3. Accept connections with accept()
4. Read and write data with read() and write()

Select all that are correct.

1. In step 4, you could also use send() and recv() to send and receive data
2. There is a missing step in between steps 1 and 2: the socket needs to be bound to a port with bind() before calling accept()
3. Assuming we want to handle more than one network connection for communication after one completes, there should be a loop around step 3
4. We do not use the connect() command in this server procedure as that is up to the client
