	Which of the following best describes cache?   stores data that will be moved from one computer to another temporarily holds data as it is about to be sent through the ALU for execution holds frequently used instructions and data to speed processing retains and permanently stores data when the computer is turned off

	ASCII is a(n):   numbering system for representing numbers with decimals. character representation standard common in older mainframe computers. encoding standard used to represent letters and characters. symbolic programming language that directly represents machine instructions.

	Which of the following is NOT true about the CPU?   The data and program instructions the CPU needs are stored in the same area in the computer system. The control unit manages the switches inside the CPU. The CPU can access the data and program instructions stored in RAM more than one million times faster than if they are left on the hard disk drive. The CPU's storage area is not big enough to hold everything it needs to process at the same time.

	Which of the following statements about the arithmetic logic unit (ALU) is FALSE?   It is part of the CPU. It uses assembly language. It is designed to test the comparison of values such as greater than, less than, or equal. It is designed to perform mathematical operations.

	__________ is a layer of storage that has even faster access than RAM.   Cache memory Flash DRAM The CPU chip

	Which of the following is TRUE about random access memory?   The type of memory chips your computer uses is independent of the type and speed of your CPU. RAM has faster access times than the hard disk drive. RAM is nonvolatile. All RAM is the same.

	Programs such as Microsoft Word are permanently stored on the hard disk because the hard disk offers ___________ storage.   volatile RAM nonvolatile cache

	The _____________of the CPU manages the switches inside the CPU.   control unit pipeline clock cycle clock speed
