The header of a window is a row of menus, buttons, and text associated with it. (The word "header" is a bit misleading. Despite the name, a header needn't be at the upper edge of its window; in fact, two of the three windows are currently displaying their headers on bottom edges.)

You cannot maximize a User Preferences window. Update (version 2.57): Now you can!, but it does not seem too useful (yet), but anyways it rules down the previous exception, what is actually good |

The accumulator is a temporary storage space for arithmetic operations. Without it, the result of every operation would have to be written to main memory, and then read back into the ALU, which is very slow. For example, to add up a list of numbers, they are loaded one by one from main memory and added into the accumulator. The final answer is then copied back to main memory.
