RARP
An abbreviation of Reverse Address Resolution Protocol. This 
is a method for providing IP Addresses to nodes on a network. 
When a node powers up, it broadcasts a RARP packet 
containing its Ethernet Address. The RARP server receives 
the packet and sends the IP Address back to the node.
Router
A device that directs network packets to the segment of the 
network for which the packet is intended, and excludes 
packets that are not intended for a segment. Routers reduce 
unnecessary network traffic and control access to segments of 
the network.
SPX
An abbreviation of Sequenced Packet Exchange. SPX is part 
of NetWare. It make sure that packets are received in the 
correct order and that there are no errors.
Subnet Mask
There are approximately 4.3 billion different addresses in the 
IP Address range of 000.000.000.000 to 255.255.255.255. 
These addresses can be divided into smaller, and much more 
manageable subnetworks, or subnets. The Subnet Mask 
identifies which part of the IP Address contains the Subnet 
Address and which part contains the host (or device) address.
TCP/IP
An abbreviation of Transmission Control Protocol / Internet 
Protocol. TCP/IP is a set of communications protocols that is 
supported by a variety of computer platforms. TCP controls 
the data transfer and IP controls the routing of the data. The IP 
Address is a unique address that identifies a device in a 
network. The IP Address has to be set in the machine by the 
System Administrator. The IP Address consists of four bytes 
of information and is expressed as decimal numbers with the 
bytes separated by dots, for example 13.1.188.2.
TIFF
An abbreviation of Tagged Image File Format. A standard file 
format commonly used for scanning. Images scanned with the 
machine are captured in a TIFF 6.0 file format.
Twisted Pair
See 10Base-T.
