Trivial File Transfer Protocol (TFTP)
A TCP/IP protocol commonly used for software downloads.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the
same collision domain regardless of their physical location or
connection point in the network. A VLAN serves as a logical
workgroup with no physical barriers, and allows users to share
information and resources as though located on the same LAN.
Wi-Fi Protected Access
WPA employs 802.1x as its basic framework for user
authentication and dynamic key management to provide an
enhanced security solution for 802.11 wireless networks.
Wired Equivalent Privacy (WEP)
WEP is based on the use of security keys and the popular RC4
encryption algorithm. Wireless devices without a valid WEP key
will be excluded from network traffic.
WPA Pre-shared Key (PSK)
PSK can be used for small office networks that may not have the
resources to configure and maintain a RADIUS server. WPA
provides a simple operating mode that uses just a pre-shared
password for network access.
