B
Baud rate
Baud was the prevalent measure for data transmission speed until replaced by a more
accurate term, bps (bits per second). One baud is one electronic state change per second.
Since a single state change can involve more than a single bit of data, the bps unit of
measurement has replaced it as a better expression of data transmission speed.
The measure was named after a French engineer, Jean-Maurice-Emile Baudot. It was first
used to measure the speed of telegraph transmissions.

C
Client program
A client program is a type of computer program that actively requests service from a
server program, which often resides on another computer.
COM port
A COM port is serial communications port (RS 232 interfaced) on a Windows-based PC.
Most PCs come with two built-in COM ports, although the number of ports can be
extended into the hundreds by installing either multiport serial boards, or network-based
serial device servers.

Data-stream transmission
Data-stream transmission refers to a series of data transmitted continuously without
interruption.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating
the configuration of computers that use TCP/IP. DHCP can be used to automatically
assign IP addresses, to deliver TCP/IP stack configuration parameters such as the subnet
mask and default router, and to provide other configuration information such as the
addresses for printer, time and news servers.
DNS
The Domain Name System (DNS) is an Internet directory service. DNS is how domain
names are translated into IP addresses, and DNS also controls email delivery.
