16 Glossary
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. |
