(5). this is true the CPU tells the RAM which address holds the data that CPU wants to read.
(6). A Character set determines in part what bits the computer stores.
(7). the binary equivalent of decimal 123456789 stores in the RAM.

(18). Input of commands that control the computer best describes a feature in a common between computer, mice, and computer
