Another method you can use to determine how much water you should drink each day is by dividing your weight in pounds by two, according to the Public Broadcasting System. The resulting number is the amount of water in ounces you should drink each day. If you weigh 150 pounds, you should consume at least 75 ounces of water per day. This is a little over nine cups of water daily.
Availability, in the context of a computer system, refers to the ability of a user to access information or resources in a specified location and in the correct format.
