1. Triple Core
2. Single Core
3. Dual Core
4. Quad Core

Explanation: – Single-core CPUs have been around since the early days of computing. They have a single processing unit that can only execute one instruction at a time. This means that they can only do one thing at a time, which can make them slow for multitasking.

Dual-core CPUs, which have two processing units, were introduced in the late 1990s. They were able to execute two instructions at a time, which made them much faster than single-core CPUs for multitasking.

Triple-core and quad-core CPUs were introduced in the early 2000s. They have three and four processing units, respectively, which can execute three and four instructions at a time. This makes them even faster than dual-core CPUs for multitasking.
