Database
A database is a collection of information that is organized so that the
contents may be easily accessed/managed.
Data Packet
In an IP network, packet switching is the method employed to transmit
data and the smallest chunk of data is called a packet (packet size

IP address onto the Internet. It is used for a PC/Server assigned with a
Static IP address and requiring multiple TCP/IP ports to be opened.
DNS
Domain Name System translates Internet domain names to IP
addresses, giving meaningful and easy-to-remember names to
otherwise arcane IP addresses.
Driver
