This was really useful in determining one's location during the times when technology wasn't that advanced yet. First is that it depends as to what time of the day is it being used. If used at day, most probably at high noon, the altitude of the sun would be measured and recorded and/or remembered. Most of the times, the latitude is determined during the day since it is much easier. At night, a star of known declination will be substituted to the sun. Most of the times, the North Star is used. Then, an almanac will be utilized to determine the declination of the Sun or the star, depending on which was used. After which, the formula is applied, which is latitude = 90 degrees - measured altitude +declination.
Answer:
Forward Compatible
Explanation:
If a piece of software designed to run on Windows XP can run on the latest version of Windows, we say the latest version of Windows is Forward Compatible.
Forward compatibility or upward compatibility is a design characteristic that allows a system to accept input intended for a later version of itself. The concept can be applied to entire systems, electrical interfaces, telecommunication signals, data communication protocols, file formats, and computer programming languages.
The objective for forward compatible technology is for old devices to recognise when data has been generated for new devices.
Passwords, TPM, and Drive Encryption.
Hope this helps. :)
