Post 3: The Processor (CPU)
The CPU (Central Processing Unit) is the main component of any computer. It’s often called the “brain” of the PC because it interprets and executes all program instructions. Without it, no computer could function.
Main features:
-
Clock speed (GHz): shows how many operations it can perform per second. For example, a 3.5 GHz CPU can complete 3.5 billion cycles in one second.
-
Cores: each core acts like a mini-processor inside the CPU. Modern CPUs usually have between 4 and 16 cores.
-
Threads: allow each core to handle multiple tasks simultaneously.
-
Cache: ultra-fast memory built into the CPU for frequently used instructions.
Real-life example:
When you open Google Chrome and Spotify at the same time, the CPU splits the instructions across its cores so you can browse and listen to music without freezing the system.
Tip:
If you want a gaming or design PC, look for processors with at least 6 cores and 12 threads
