How many sockets can be created from a port?
655
Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K.
@premktiw: Yes, multiple client sockets can be bound to the same local IP/port pair at the same time, if they are connected to different server IP/Port pairs so the tuples of local+remote pairs are unique.
Why does TCP socket programming need two sockets(one welcome socket and one connection socket) but UDP only needs one?
A port is a number between 1 and 65535 inclusive that signifies a logical gate in a device. Every connection between a client and server requires a unique socket. For example: 1030 is a port.
It's operating system dependent.
For Windows, look here for the MaxConnections entry.
For Linux, look here as the comment on question says.
