Select the category of computers that includes personal computers, laptops, smartphones, and other single-user devices.

Microcomputers represent a category of computers designed for individual use, typically catering to a single user. This category encompasses personal computers, laptops, and smartphones, which are all systems intended for personal productivity, entertainment, communication, and various applications that support individual tasks.

Microcomputers are characterized by their relatively smaller size and lower processing power compared to larger computer systems, yet they are versatile and widely used in everyday environments. The accessibility and affordability of microcomputers have led to their proliferation in homes, schools, and businesses, making them a staple in the technology landscape.

On the other hand, other categories like mainframe computers, supercomputers, and servers are designed for different functionalities and workloads. Mainframe computers are used for large-scale data processing and enterprise applications, supercomputers are specialized for complex calculations and scientific simulations, and servers are built to manage network resources and serve multiple users simultaneously. These distinctions highlight why microcomputers are the correct choice for individual user devices.
