Chapter 02 Hardware and Software TRUEFALSE 1. When making hardware decisions, the overriding considerations of a business should be technology cost. (A) True (B) False Answer : (B) 2. Because of the electromechanical processes involved in using primary storage, it is considerably slower than secondary storage. 3. The ability to process (organize and manipulate) data is a small aspect of a computer system. 4. The components responsible for processing-the central processing unit (CPU) and memory-are housed together in the same box or cabinet, called the system unit. (A) True (B) False Answer : (A) 5. The clock speed of a central processing unit (CPU) is independent of machine cycle time. 6. RAM stands for random access memory, a form of memory that holds its contents even if the

current is turned off or disrupted. (A) True (B) False Answer : (B) 7. A multicore microprocessor combines two or more independent processors into a single computer so that they can share the workload and boost processing capacity. (A) True (B) False Answer : (A) 8. Compared to secondary storage, main memory offers the advantages of non-volatility, greater capacity, and greater economy. 9. Disk mirroring is a method of storing data that generates extra bits of data from existing data, allowing the system to create a "reconstruction map" so that if a hard drive fails, it can rebuild lost data. 10. With the redundant array of independent/inexpensive disks (RAID) approach, data can be split and stored on different physical disk drives using a technique called mirroring to evenly distribute the data. 11. The overall trend in secondary storage is toward use of indirect access methods and increased volatility.

(A) True (B) False Answer : (B) 12. Optical mark recognition (OMR) is a technology from the 1950s still used to speed up the processing of checks. 13. Organic light-emitting diode (OLED) monitors use less power than light-emitting diode (LED) monitors. (A) True (B) False Answer : (A) 14. As the difference among computer manufacturers in the arenas of price and performance narrows, support for green computing is emerging as a new business strategy for these companies to distinguish themselves from the competition. (A) True (B) False Answer : (A) 15. Application software is a set of programs designed to coordinate the activities and functions of the hardware and various programs throughout the computer system. 16. Information systems that operate within the workgroup sphere of influence support a firm in its interaction with customers, suppliers, shareholders, competitors, special-interest groups, the financial community, and government agencies.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
