231. Computers process data into information by working exclusively with____________?
- A. multimedia
- B. word
- C. numbers
- D. characters
Explanation: Computers represent all forms of data internally as numeric binary values, including text, images, and sound. Thus, numbers are the underlying form even when the displayed content is characters or multimedia.
Correct answer: numbers232. ______________is the science that attempts to produce machines that display the same type of intelligence that humans do?
- A. Nanoscience
- B. Nanotechnology
- C. Simulation
- D. Artificial intelligence (Al)
Explanation: Artificial intelligence aims to make machines perform tasks associated with human intelligence, such as learning, reasoning, and problem-solving. Nanoscience and nanotechnology concern extremely small-scale materials and devices, not machine intelligence.
Correct answer: Artificial intelligence (Al)233. Which of the following is NOT one of the four major data processing functions of a computer?
- A. gathering data
- B. processing data into information
- C. analyzing the data or information
- D. storing the data or information
Explanation: The standard functions are gathering or inputting data, processing it, producing information, and storing it. Analysis may be performed during processing, but it is not normally listed as one of the four basic functions.
Correct answer: analyzing the data or information234. The task of performing operations like arithmetic and logical operations is called____________?
- A. Processing
- B. Storing
- C. Editing
- D. Sorting
Explanation: Arithmetic and logical operations transform or evaluate data, so they are part of processing. Storing, editing, and sorting describe other specific activities rather than the general operation named here.
Correct answer: Processing235. _______________is the ability of a device to "jump" directly to the requested data?
- A. Sequential access
- B. Random access
- C. Quick access
- D. All of the above
Explanation: Random access allows a device to go directly to a requested location instead of reading all preceding data. Sequential access must proceed in order, and quick access is not the standard technical term.
Correct answer: Random access236. You use a(n)___________such as a keyboard or mouse, to input information?
- A. output device
- B. input device
- C. storage device
- D. processing device
Explanation: A keyboard or mouse sends data and commands into the computer, so each is an input device. Output devices send processed results from the computer to the user.
Correct answer: input device237. On-line real time systems become popular in______________generation?
- A. First Generation
- B. Second Generation
- C. Third Generation
- D. Fourth Generation
Explanation: Third-generation computers, based mainly on integrated circuits, supported the wider adoption of online real-time processing systems. Earlier generations were more commonly associated with batch processing.
Correct answer: Third Generation238. Which of the following are the functions of a operating system?
- A. Allocates resources
- B. Monitors Activities
- C. Manages disks and files
- D. All of the above
Explanation: An operating system allocates hardware resources, monitors system activities, and manages disks and files. Since all three are OS functions, the combined option is correct.
Correct answer: All of the above239. RAM can be treated as the____________for the computer's processor?
- A. factory
- B. operating room
- C. waiting room
- D. planning room
Explanation: RAM acts like a waiting room because it temporarily holds programs and data that the processor is about to use. It provides fast access, unlike long-term storage.
Correct answer: waiting room240. Data becomes____________when it is presented in a format that people can understand and use.
- A. processed
- B. graphs
- C. information
- D. presentation
Explanation: Raw data becomes information after it is processed and presented in a meaningful, usable form. Graphs and presentations are formats that may display information, not the result itself.
Correct answer: information
