Using the Winsock Control in Client/Server Applications  By S.S.
Ahmed  The Internet Transfer Control (ITC) is a handy control
for Internet programming, but there is another control that is
even more robust and helps programmers to create more flexible
applications. The Winsock control comes with Visual Basic 6.0
(VB6) and is used to create applications that access the low-
level functions of the Transmission Control Protocol/Internet
Protocol (TCP/IP).  TCP/IP is a specification that defines a
series of protocols used to standardize how computers exchange
information with each other. TCP/IP provides communication
across interconnected networks that use diverse hardware
architectures and various operating systems. The protocols in
TCP/IP are arranged in a series of layers known as a protocol
stack. Each layer has its own functionality.  Winsock is a
standard that is maintained by Microsoft. This standard is
basically a set of routines that describe communications to and
from the TCP/IP stack. These routines re
