The vulnerabilities applied to open Wi-Fi, as well as networks secured by the WEP and WPS standards. But the problem isnât simply a matter of networks lacking sufficient protection. Most end users are unaware of the risks involved in using public Wi-Fi. They treat it as just another network, and use it to send sensitive information via email or connect to online banking or e-commerce services.

A year is a leap year if it is divisible by 4, but century years are not leap years unless they are divisible by 400. So, the years 1700, 1800, and 1900 were not leap years, but the year 2000 was, which is why in a given 100 years, there are 24 leap years and 76 ordinary years. Why Do We Need Leap Years? The actual length of a year (the revolution of Earth around the Sun) is 365.2422 days. If we didn't have leap years, the seasons would shift about a quarter of a day every year, and after 100 years the seasons would be off by 25 days. The extra leap day adjusts this drift. it is divisible by 400.
