computer performance

1. clock speed

   • what
     • what is clock speed?
       • the operating speed of a computer or its microprocessor, expressed in cycles per second
   • how
     • how does it work?
       • The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).

2. cores

   • how
     • how does it work?
       • Processor cores are individual processing units within the computer's central processing unit (CPU)
   • what
     • what are cores?
       • a core is a small CPU or processor built into a big CPU or CPU socket.

3. cache

   • what
     • what is a cache?
       • a cache is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.
   • how
     • how does it work?
       • Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU.

4. RAM

   • what
     • what does RAM mean?
       • random access memory
   • how
     • how does RAM work?
       • It works by storing common data that programs are in constant use of, rather than storing the data on a much slower medium like a Solid State Hard Drive (or SSD).
