Question ID:PT1 S3 Q16 Passage:Computer operating system software has become increasingly standardized. But when a large business with multiple, linked computer systems uses identical operating system software on all of its computers, a computer vandal who gains access to one computer automatically has access to the data on all the computers. Using a program known as a “virus,” the vandal can then destroy much of the data on all the computers. If such a business introduced minor variations into its operating system software, unauthorized access to all the computers at the same time could be virtually eliminated. Furthermore, variations in operating system software can be created without any loss of computer compatibility to the business. Therefore, it is advisable for businesses to implement such variations. Stem:Which one of the following can be inferred from the passage? Correct Answer Choice:CChoice A:If a business does not introduce variety into its computer operating systems, it will lose data on its computers because of damage from virus programs. Choice B:If a computer virus program is introduced into a business’ computer, all of the data on that computer will be destroyed. Choice C:If a business introduces variety into its linked computer operating systems, it will have increased overall protection for its systems, but will not have protected every computer from viral invasion. Choice D:If a business does not have multiple, linked computer systems, its computers cannot be protected from computer viruses. Choice E:If minor variations are created in computer operating system software, it will be easier to access the data on the computers that use that software.
