Difficulty: Challenging AACSB: Analytical thinking LO: 5-1: What is IT infrastructure and what are the stages and drivers of IT infrastructure evolution? 8 30) Explain why standards are so important in information technology. What standards have been important for the growth of Internet technologies? Answer: Standards are important because they result in different manufacturers creating products that can be used either with each other or to communicate with each other. For example, without standards, each light-bulb manufacturer would have to also create specific light-bulb sockets for use with their light bulbs. In the same way, computers and computer technology have been enabled through standards. Standards have allowed many different manufacturers to contribute to the same, standardized definitions of a technological application. For example, the ASCII data standards made it possible for computer machines from different manufacturers to exchange data, and standardized software languages have enabled programmers to write programs that can be used on different machines. The standards that have been important for the growth of the Internet include TCP/IP, as a networking standard, and WWW standards for displaying information as web pages, including HTML. Difficulty: Challenging AACSB: Analytical thinking LO: 5-1: What is IT infrastructure and what are the stages and drivers of IT infrastructure evolution? 31) Have mainframes disappeared? Answer: Mainframes have not disappeared. They continue to be used to reliably and securely handle huge volumes of transactions, for analyzing very large quantities of data, and for handling large workloads in cloud computing centers. The mainframe is still the digital workhorse for banking and telecommunications networks that are often running software programs that are older and require a specific hardware platform. Currently, mainframes process 30 billion business transactions per day, and 80 percent of the world's corporate data also originates on the mainframe.
