You probably use a computer every day. Maybe for homework. Maybe for games. But sometimes it feels hard to remember the English names for all the computer parts.
Don’t worry. This guide makes it easy.
In this lesson, you will learn the most common parts of a computer in English with simple meanings and real-life example sentences. The words are easy enough for kids and beginners. You can also use this list for school projects, speaking practice, vocabulary notebooks, flashcards, and classroom posters.
When I design visual sheets for kids, I always use clear pictures beside each word. Students remember computer vocabulary much faster when they can see the object while reading the name.
