Completion 20. A(n) is an integrated circuit designed to process instructions. 21. Processors based on technology dominate tablet computers and smartphones. 22. processors are found in Microsoft's Surface tablets, Apple's iPads and iPhones, and Samsung's lineup of Galaxy phones. 23. Microprocessors are hard-wired to perform a limited, preprogrammed set of activities called a(n) NEP 24. The and subtraction. 25. The ALU uses to hold data that is being processed. 26. When a program begins, the memory address of the first instruction is placed in a part of the microprocessor's control unit called a(n) is the part of the microproces that performs arithmetic operations, such as addition 27. In a processor, the timing device that sets the pace for executing instructions is called the 28. A microprocessor that contains circuitry for more than one processing unit is called processor. 29. A(n) is special high-speed memory that allows a microprocessor to access data more rapidly than from memory located elsewhere on the system board. 30. storage represents data as microscopic light and dark spots on a dise surface. 31. Remote storage that is available as an Internet service is called storage.
