First, preemptive and preventive uses of force are often justified by claiming either that there is substantial risk of a future attack or that it is difficult to ascertain how dangerous the target is.
Short-Term Memory: Up to 7 Items, But Highly Volatile. Many psychology experiments have shown that our short-term memory can hold only a limited number of separate items. The average is about 7 items, plus or minus 2, depending on the individual. You can easily confirm this by reading someone a series of words that have no connection with one another, then asking this person to repeat them.
Most modern computers store memory in units of 8 bits, called a byte (also called an octet). Arithmetic in such computers can be done in bytes, but is more often done in larger units called (short) integers (16 bits), long integers (32 bits) or double integers (64 bits). Short integers can be used to store numbers between 0 and 216 - 1, or 65,535.
