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.
NFS Network File System is a protocol suite developed and
licensed by Sun Microsystems that allows different makes of
computers running different
operating systems to share files and disk storage. NFS is
implemented using a connectionless protocol (UDP) in order
to make it stateless.
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.
Object Identifiers (OID) The SNMP manager or the management application uses a
well-defined naming syntax to specify the variables to the
SNMP agent. Object names in this syntax are called Object
Identifiers (Object IDs or OIDs). OIDs are series of numbers
that uniquely identify an object to an SNMP agent. OIDs are
arranged in a hierarchical, inverted tree structure.
The OID tree begins with the root and expands into branches.
Each point in the OID tree is called a node and each node will
