An 8-bit computer is a type of computer architecture that processes data in 8-bit chunks. This means it can handle 256 different values at a time, which limits its ability to perform complex calculations compared to modern systems. Popular in the late 1970s and 1980s, these computers were often used in home computing and gaming. Examples of 8-bit computers include the Commodore 64 and the Apple II. These systems typically featured simple graphics and sound capabilities, making them suitable for basic applications and games. Despite their limitations, they laid the groundwork for future advancements in computer technology.
