Information Systems and Computer Applications CLEP Prep Practice Exam

An operating system is not a type of data (choice A). Data refers to the different types of information that can be stored, processed, and communicated by a computer. An operating system, on the other hand, manages and controls these activities.

An operating system is also not a type of computer language (choice B). Computer languages are used to write software programs and give instructions to the computer, whereas an operating system is a software program itself.

Additionally, an operating system is not a physical device (choice C). Physical devices are tangible objects, such as a computer or phone, that can be touched and interacted with. An operating system is an intangible program that runs on these devices to manage their functions.

Therefore, the most accurate answer is D A software program that manages and coordinates the activities of the computer.
