Data transmitted on a network consists of units called
packets. Each packet contains a payload (the data), plus
overhead information such as where it came from (source
address) and where it should go (destination address).
Packet Internet (or Inter-Network) Groper
A program used to verify whether the host associated
with an IP address is online. It can also be used to reveal
the IP address for a given domain name.
A physical access point to a device such as a computer
or router, through which data flows into and out of the
device.
A set of rules governing the transmission of data. In
order for a data transmission to work, both ends of the
connection have to follow the rules of the protocol.
In a physically separate location. For example, an
employee away on travel who logs in to the companyʼs
intranet is a remote user.
Registered Jack Standard-45
The 8-pin plug used in transmitting data over phone lines.
Ethernet cabling usually uses this type of connector.
Remote Monitoring
Extensions to SNMP, provide comprehensive network
monitoring capabilities.
Forwarding data between your network and the
Internet on the most efficient route, based on the dataʼs
destination IP address and current network conditions. A
device that performs routing is called a router.
Simple Network Management Protocol
The TCP/IP protocol used for network management.
Spanning Tree Protocol
The bridge protocol to avoid packet looping in a
complicate network.
A subnet is a portion of a network. The subnet is
distinguished from the larger network by a subnet mask
which selects some of the computers of the network
and excludes all others. The subnetʼs computers remain
physically connected to the rest of the parent network,
but they are treated as though they were on a separate
network. See also network mask.
