	Glossary
	connect to the Internet via PPP, you might want to set your
	machine's MTU to 576 too. Most Ethernet networks, on the
	other hand, have an MTU of 1500.
Network Mask	A 32-bit number used to group IP addresses together or to
	indicate the range of IP addresses on a single IP network/
	subnet/supernet. There is a group of addresses assigned to
	each network segment. For example, the mask 255.255.255.0
	groups together 254 IP addresses. If we have, as another
	example, a sub-network 192.168.16.64 with mask
	255.255.255.224, the addresses we may assign to computers
	on the sub-network are 192.168.16.65 to 192.168.16.94, with
	a broadcast address of 192.168.16.95.
	A number used by software to separate the local subnet
	address from the rest of a given Internet protocol address
	Network masks divide IP addresses into two parts (network
	address and address of a particular host within the network).
	Mask have the same form as IP addresses (i.e.
	255.255.255.0), however, its value is needed to be
	understood as a 32-bit number with certain number of ones
	on the left end and zeros as the rest. The mask cannot have an
	arbitrary value. The primary function of a subnet mask is to
	define the number of IP hosts that participate in an IP subnet.
	Computers in the same IP subnet should not require a router
	for network communication.
NTP	Network Time Protocol. A standard for synchronizing your
	system clock with the ``true time'', defined as the average of
	many high-accuracy clocks around the world.
Parity	In serial communications, the parity bit is used in a simple
	error detection algorithm. As a stream of data bits is formed,
	an extra bit, called the parity bit, is added. This bit is set on
	(1) or off (0), depending on the serial communications
	parameters set in the UART chip.
