Wireless N Networking refers to computers networks that follow specifications in IEEE 802.11n standard. Development of 802.11n began in 2002 & was published in 2009. Alternate names such as "Wireless N" and "Draft N" were coined to distinguish early products whose development started before 2009.
Sometimes 802.11g is referred as "G". It is an IEEE wireless standard. 802.11g was an improvement on 802.11a and 802.11b and was released in June 2002. 802.11g supports WLAN (Wireless LAN) communication between host computers, routers, and other consumer devices.
802.11a is an IEEE standard used for transmission of data over a wireless network. The base version of these standards (802.11) came in 1997 with amendments released subsequently. Both 802.11a and 802.11b released in September 1999. 802.11a networks operate at radio frequencies b/w 5.725 and 5.850 GHz

Resin tooth filling typically contains a filler particle such as quartz, which provides the mixture's strength and color. It is costly as compared to silver tooth filling.
In some cases, the change in period blood color can indicate a health problem like fibroids, low estrogen levels, and even vaginosis.
