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.
What Is Zumba? Zumba is a fusion of Latin and international music combined with a heart-pumping cardio workout. It was founded in the '90s by Alberto Beto Perez, a fitness instructor from Colombia, when he forgot his music and improvised a traditional aerobics class with Latin music and moves that he grew up dancing to.
