Body
I wanted to know the exact function of bind() in TCP. What does it mean by 'binding' a local address to the socket? If it's assigning a port number to the socket, then why don't we use it in the client? I know that port is assigned by OS automatically in the client side, but I'm not getting the big picture of how all of this works. After bind(), we listen(). How is the bind related to listen()? Will the listen() know that bind() has been executed? If so, what changes does bind() make so that it is known? I mean, how does returning zero for successful execution help? I've gone through many definitions, but no where I could get all of this in detail. So if anyone can please explain this to me, I will be grateful.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
