File Server A generic term for a device that provides files upon
request. It overlaps other commonly used terms such as Novell
server, NT server, and Unix server, which are more specific
because they indicate the operating system running in the file
server. File servers often provide other functions such as
remote access, DHCP, or security related services.
Frame Data organized in bytes encapsulated with a header and
a trailer containing information regarding the data. Frame and
packet are sometime used interchangeably.
Frame Loss Rate Percentage of frames that should have been
forwarded by a network device under steady state (constant)
load that were not forwarded due to lack of resources.
Frame Type The format of the frame. Some examples are:
SNAP/IP, SNAP/IPX, 802.3/802.2, EthernetII/IP,
EthernetII/IPX, 802.3/IPX, 802.2/IPX.
FTP File Transfer Protocol - Internet protocol for transferring

Hop A data link through a bridge or router between stations on
a network. For example: Agilent.com is 6 hops away from my
PC.
ICMP Internet Control Message Protocol - The IP layer
protocol for handling errors and control messages.
IP Internet Protocol - The protocol developed and used in the
Internet. It is now used in nearly all public and private
networks. It provides an addressing structure that allows
relaying of packets in a manner that is logically separated from
the underlying physical network. It is a connectionless, best
effort protocol designed to work across dissimilar networks.
IP Address A four-byte address always written in decimal with
each byte separated by dots. This is an address normally
assigned through software and associated with a hardware
address of a network interface card. It can also be associated
with a resource on the network such as an SNMP agent.
IPX Internetwork Packet Exchange - Novell Netware’s network
layer protocol, it handles network addressing, routing and
packets.
