DDNS - Dynamic DNS (DDNS) is a method of updating, in real time, a DNS to point to
a changing IP address on the Internet. This is used to provide a persistent domain
name for a resource that may change location on the network.
SSID - Service Set Identifier (SSID) is a sequence of characters that uniquely names a
wireless local area network (WLAN). The maximum length of the SSID is currently 32
characters long.
MAC Clone - Most ISPs bind an IP with a MAC address to constrain the users to share
the network. MAC Clone function is used to clone your computer’s MAC address to
the router to lift the network sharing constraint.
WMM - Wireless Multimedia Extensions (WME), also known as Wi-Fi Multimedia
(WMM), is a Wi-Fi Alliance interoperability certification, based on the IEEE 802.11e
standard. It provides basic Quality of service (QoS) features to IEEE 802.11 networks.
WEP - Wired Equivalent Privacy (WEP) is a security algorithm for IEEE 802.11 wireless
networks. WEP, recognizable by the key of 10 or 26 hexadecimal digits, is widely in
use and is often the first security choice presented to users by router configuration
tools.
WPA/WPA2 - Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are
two security protocols and security certification programs developed by the Wi-Fi
Alliance to secure wireless computer networks. The Alliance defined these in
response to serious weaknesses researchers had found in the previous system, WEP
(Wired Equivalent Privacy).
RADIUS - Remote Authentication Dial in User Service (RADIUS) is a networking
protocol that provides centralized Authentication, Authorization, and Accounting
(AAA) management for computers to connect and use a network service.
QoS - Quality of service (QoS) is a technology that used to solve the issues of network
latency and blocking by setting several related aspects.
DoS - Denial of service (DoS) usually refers to an attack that attempts to make
network resource unavailable to its intended users by flooding a network or server
with requests and data.
NTP - Network Time Protocol (NTP) is a networking protocol for clock
synchronization between computer systems over packet-switched, variable-latency
data networks.
Daylight Saving Time - Daylight Saving Time (DST) which also called summer time in
several countries in British English, and European official terminology, is the practice
of advancing clocks so that evenings have more daylight and mornings have less.
Typically clocks are adjusted forward one hour near the start of spring and are
adjusted backward in autumn.
