Computer Hardware in English: Complete Guide to “Phần cứng máy tính gọi là gì trong tiếng anh”

“Phần cứng máy tính” translates directly to “computer hardware” in English. This comprehensive guide will explore all aspects of computer hardware, from basic definitions to advanced components, helping you understand the English terminology for every part of a computer system.

What is Computer Hardware?

Computer hardware refers to the physical components that make up a computer system. Unlike software (which are programs and operating systems), hardware includes all the tangible parts you can see and touch. According to the National Institute of Standards and Technology (NIST), hardware is classified into four main categories:

  1. Input devices – Components that allow users to enter data (keyboard, mouse)
  2. Processing devices – Components that execute instructions (CPU, GPU)
  3. Storage devices – Components that store data (HDD, SSD, RAM)
  4. Output devices – Components that display or produce results (monitor, printer)
