21. Which of the following is a type of binary code? • ASCII • Extended ASCII • EBCDIC • Unicode • All of the above. These are all binary codes that are used to relay data and instructions to and from the CPU. Both of the first three use various eight-bit combinations in binary form. Unicode uses 16 bits to represent characters

22. The section(s) of the CPU are the: • processing unit. • power supply and processor. • motherboard. • RAM and ROM memory. • ALU and control unit.

23. The section(s) of the CPU are the: • processing unit. • power supply and processor. • motherboard. • RAM and ROM memory. • ALU and control unit. The arithmetic logic unit, which performs mathematics and logical operations, and the control unit, which fetches, decodes, retrieves, and stores, are the two main sections of the CPU. The CPU consists of millions of tiny transistors that allow it to interpret and manipulate input
