2. Single-core - Wikipedia

   en.wikipedia.org/wiki/Single-core

   A computer using a single core CPU is generally slower than a multi-core system. Single core processors used to be widespread in desktop computers, but as applications demanded more processing power, the slower speed of single core systems became a detriment to performance. Windows supported single-core processors up until the release of ...

3. Multithreading (computer architecture) - Wikipedia

   en.wikipedia.org/wiki/Multithreading_(computer...

   A process with two threads of execution, running on a single processor . In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.

4. Central processing unit - Wikipedia

   en.wikipedia.org/wiki/Central_processing_unit

   A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations.

8. Computer performance - Wikipedia

   en.wikipedia.org/wiki/Computer_performance

   In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
