1 Data registers can hold numeric values such as integer and, in some architectures, floating-point values, as well as characters, small bit arrays and other data. 2  In some older and low end CPUs, a special data register, known as the accumulator, is used implicitly for many operations.
A commander-in-chief is the person or body that exercises supreme operational command and control of a nation's military forces or significant elements of those forces. In the latter case, the force element is those forces within a particular region, or associated by function.
Practically, the sitting president, as Commander In Chief, has the highest military authority. However, in 1976, President Gerald Ford posthumously awarded George Washingtonâ¦ with the rank of General of The Armies of The United States, stating that he would forever outrank all officers past, present, and future. So technically, he has the highest rank of any American.
