DHCP
Dynamic Host Configuration Protocol, DHCP, is a protocol for assigning dynamic IP addresses to devices on a
network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In
some systems, the device's IP address can even change while it is still connected. DHCP also supports a mix of static
and dynamic IP addresses. Dynamic addressing simplifies network administration because the software keeps track of
IP addresses rather than requiring an administrator to manage the task. This means a new computer can be added to a
network without the hassle of manually assigning a unique IP address. Many ISPs use dynamic IP addressing for dial-
up users.
NMS (Network Management Station)
Includes such management software as HP Openview and IBM Netview.
PC Card
A computer device packaged in a small card about the size of a credit card and conforming to the PCMCIA standard.
PDA (Personal Digital Assistant)
A handheld device.
SNMP
Simple Network Management Protocol
SSID
A Network ID unique to a network. Only clients and access points that share the same SSID are able to communicate
with each other. This string is case-sensitive. Wireless LANs offer several security options, but increasing the security
also means increasing the time spent managing the system. Encryption is the key. The biggest threat is from intruders
coming into the LAN. You set a seven-digit alphanumeric security code, called an SSID, in each wireless device and
they thereafter operate as a group.
TKIP
Temporal Key Integrity Protocol. TKIP is a protocol used in WPA. It scrambles the keys using a hashing algorithm and,
by adding an integrity-checking feature, ensures that the keys haven't been tampered with.
VPN (Virtual Private Network)
A VPN uses encryption and other security mechanisms to ensure that only authorized users can access the network and
that the data cannot be intercepted.
WLAN (Wireless Local Area Network)
A type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes.
