Theoretical vs. Actual Network Speeds. The performance of Wi-Fi networks practically never approach these theoretical maximums. 802.11b networks, for example, generally operate no faster than about 50 percent of theoretical peak, around 5.5 Mbps. Likewise, 802.11a and 802.11g networks generally run no faster than 20 Mbps.
It is not unusual to see aerobic dance and Zumba, a form of dance to Latin music, offered in neighborhood gyms and community centers. Both have similarities but some differences for participants.
Zumba. Zumba is a dance fitness program created by Colombian dancer and choreographer Alberto Beto Perez during the 1990s. Zumba involves dance and aerobic elements. Zumba's choreography incorporates hip-hop, soca, samba, salsa, merengue, mambo, martial arts, and some Bollywood and belly dance moves. Squats and lunges are also included. Zumba Fitness, an organization that sells Zumba videos and products, does not charge licensing fees to gyms or fitness centers.
