Question 17 - 26, True/False (2 pts. ea.) 17 The purpose of cache memory is to store frequently referenced program instructions durine processing. 18. The speed at which the CPU executes a number of instructions while synchronizing them to all the various components of a computer is regulated by the clock rate. 19. The capacity of the CPU's registers to hold a specific number of bits for processing at the same time is designated as the Word size. 20. The only function of the IP register within the CPU is to hold temporary data being process. 21. Pipelining improves CPU performance by allowing multiple instructions to execute simultaneously in different stages of the fetch and execute cycle. _ 22. A Halt statement is an example of a conditional Branch of a sequence control instruction 23. Arithmetic shift operations preserve the sign bit, while the logical shift operations do not. 24. Primary storage devices support immediate execution of programs, while secondary storage devices provide long term storage of programs and data._ 25. Magnetic secondary storage devices store data bits as variations of laser light reflection due to their magnetic orientation. 26. Important features of primary storage is the data access speed and the number of bits that can be read in a single operation
