Answer True False Question (MIS, Ch 4) Businesses that handle large volumes of retail transactions often store this data in a corporate data center on mainframe computers, which many I.T. professionals fondly refer to as “big iron” in their lingo. Answer True False Question (MIS, Ch 4) Because _____ reduces the amount of paper in organizations, some of its most enthusiastic adopters are companies in paper-intensive fields such as law, retail, insurance, and banking. Answer processing OMR imaging printing Question (MIS, Ch 5) To accelerate their work, application developers can use one of several _____ programming languages, such as Microsoft Visual Basic, Borland Delphi, Micro Focus COBOL, ASNA Visual RPG, and Visual C++. Answer visual Question (MIS, Ch 4) What factors make one computer more powerful than another? Answer The two major factors to consider are processing speed and memory capacity. A computer’s speed is determined, among other factors, by the CPU clock rate (measured in MHz or GHz), and the amount of information the CPU can process per cycle (determined by the size of the data word and the capacity of internal data communication, which is often referred to as bus width). However, the architecture of the various computer components also plays a significant role in determining processing speed. To mention one, consider the discussion of multi-core CPUs. When two computers are built with the same components except the number of cores, the computer with the greater number of cores is faster.
