IPA IP 2025 Question 67
A question IPA Japan published in 令和7年度 ITパスポート試験 公開問題 問67, translated into English. ITPEC is based on the same exams.
Which of the following is the hardware for drawing processing that has functions such as accelerating 3D image processing and making video smooth?
Explanation
GPU — the Graphics Processing Unit is the processor dedicated to drawing images.
A GPU has a large number of simple arithmetic units that work in parallel, which suits graphics: computing the position and colour of very many polygons and pixels at once. Taking this work from the CPU accelerates 3D image processing and lets video play smoothly at a high frame rate. The same parallel power is now also used for AI and other heavy calculation.
Answer (b)
Why not others:
- •(a) — CGI (Common Gateway Interface) is a mechanism by which a web server runs a program and returns its output; it is not hardware
- •(c) — a GUI (graphical user interface) is a way of operating a computer with icons, windows and a pointer, not drawing hardware
- •(d) — a UPS (uninterruptible power supply) keeps supplying power from a battery for a time when the mains power fails
Key rule: GPU = parallel processor for graphics (and AI calculation); GUI = the on-screen interface; CGI = web server programs; UPS = backup power.
