Q1. What is the primary purpose of technology in everyday life?
-
A. to enable human communication
-
B. to provide information for survival
-
C. to improve quality of life ✓
-
D. to enhance technological advancement
Explanation: Technology exists to solve problems and make life better - healthier, safer, more comfortable, more productive. Communication and information access are important functions, but improving life overall is the broader primary purpose.
Q2. What is the term used to describe a computer program designed for specific purposes and runs on personal computers.
-
A. system software
-
B. application software ✓
-
C. programmable logic controller (PLC)
-
D. network software
Explanation: Application software is built for specific user tasks such as word processing, browsing, or gaming. System software, by contrast, manages the computer itself and provides the platform applications run on.
Q3. Which part of a computer carries out its calculations and runs programs?
-
A. The CPU ✓
-
B. The keyboard
-
C. The printer
-
D. The screen
Explanation: The central processing unit (CPU) executes instructions and performs calculations. The keyboard and screen are input/output devices, and the printer only outputs documents.
Q4. What is the primary purpose of a computer?
-
A. to store data
-
B. to process information ✓
-
C. to generate electricity
-
D. to communicate with other systems
Explanation: A computer's defining purpose is processing information: it accepts input, transforms data through computation, and produces output. Storage and communication are supporting functions, and generating electricity is not a computer function at all.
Q5. Which of the following best describes the core operation of a computer?
-
A. computes data
-
B. processes information ✓
-
C. store data
-
D. transmits information
Explanation: 'Processes information' best captures what a computer does: it transforms input data into meaningful output. Storage and transmission support the process, and 'computes data' is narrower than what computers actually do.
Q6. Which type of computer is designed to provide services - such as files, web pages, or email - to other computers over a network?
-
A. A server ✓
-
B. A supercomputer
-
C. A laptop
-
D. A calculator
Explanation: Servers exist to answer requests from client computers, providing files, web pages, email, and other network services. Supercomputers focus on massive computation, while laptops and calculators are endpoint devices.
Q7. Computers process information using which of these?
-
A. Electrical circuits ✓
-
B. Steam pressure
-
C. Hydraulic pipes
-
D. Chemical reactions
Explanation: Computers represent data as tiny electrical signals switched through billions of circuits etched onto chips.
Q8. Technology is best described as the application of knowledge and tools to ___.
-
A. solve human problems ✓
-
B. create artwork only
-
C. play professional sports
-
D. replace all human jobs
Explanation: Technology applies knowledge, tools, and techniques to solve practical problems and meet human needs.
Q9. What is the primary function of a computer?
-
A. It processes information and stores it in memory ✓
-
B. It is designed only for entertainment
-
C. It generates electricity for homes
-
D. It runs without any software
Explanation: Computers take in data, process it, store results in memory, and output information - that combination is their core function. The distractors describe things computers plainly do not do.
Q10. In computer graphics, what is the process of generating an image from a wireframe or 3D model called?
-
A. rendering ✓
-
B. printing
-
C. scanning
-
D. downloading
Explanation: Rendering is the process of generating a final image from a 2D or 3D model using software.
