single-core
A "single-core" processor refers to a computer chip that has only one core, which is the part of the processor that performs tasks. This means it can handle one operation at a time, making it less efficient for multitasking compared to multi-core processors. Single-core processors were common in earlier computers but are now largely replaced by more advanced options.
Despite their limitations, single-core processors can still be effective for simple tasks like browsing the internet or using basic applications. They are often found in older devices or low-power gadgets, such as some models of smartphones and embedded systems.
