Consider the following 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$()$

Which of the following statements are correct? $($select one or more$)$

Group of answer choices

accept $()$ returns the same file descriptor as the one we create with socket$()$ call.

In step $4,$ you could also use send$()$ and recv$()$ to send and receive data

Assuming we want to handle more than one network connection for communication after one completes, there should be a loop around steps $3$ and $4$

There is a missing step in between steps $1$ and $2$: the socket needs to be bound to a port with bind$()$ before calling listen$()$

We do not use the connect$()$ command in this server procedure; connect$()$ is used by the client.$$
