will be installed in server computer.
It is the responsibility
of database or network administrator to install server software in server
computer.
Every server computer is
connected to a network. We can quickly identify a server computer by using the
IP Address of the computer. If we want to develop any program to communicate
with they are server with database three information’s. They are
