Glossary of Terms ROM: Read-Only Memory, a memory device that retains its information even when power to it is removed. A ROM version of a network device does not need to download, since the ROM contains the entire executable code and thus never needs to reload it. Frequently the ROM is provided as "flash ROM", which can be reprogrammed by downloading if the user chooses. Router: Device capable of filtering/forwarding packets based upon data link layer information. Whereas a bridge or switch may only read MAC layer addresses to filter, routers are able to read data such as IP addresses and route accordingly. RTEL: Lantronix' "reverse Telnet" software allows hosts using TCP/IP to establish a session with a device attached to a terminal server port. Server: A computer that provides resources to be shared on the network, such as files (file server) or terminals (terminal server). Session: A connection to a network service. Shared Ethernet: Ethernet configuration in which a number of segments are bound together in a single collision domain. Hubs produce this type of configuration where only one node can transmit at a time. SLIP: Serial Line Internet Protocol, a protocol for running TCP/IP over serial lines. SNA: Systems Network Architecture. IBM's layered protocols for mainframe communications. SNMP: Simple Network Management Protocol, allows a TCP/IP host running an SNMP application to query other nodes for network-related statistics and error conditions. The other hosts, which provide SNMP agents, respond to these queries and allow a single host to gather network statistics from many other network nodes. Source Code: Programs in an uncompiled or unassembled form. 11-14 DSTni-XPress DR User Guide
