Computer perfomance

1. RAM

   • how ?
     • RAM is considered volatile memory, which means that the stored information is lost when there is no power.
   • what ?
     • RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes.
   • why ?
     • RAM allows your computer to perform many of its everyday tasks, such as loading applications, browsing the internet, editing a spreadsheet, or experiencing the latest game.

2. clock speed

   • how ?
     • The clock speed - also known as clock rate - indicates how fast the CPU can run.
       • In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor.
     • how
   • what ?
     • the operating speed of a computer or its microprocessor, expressed in cycles per second (megahertz).
       • why ?
         • A computer's processor clock speed determines how quickly the central processing unit (CPU) can retrieve and interpret instructions.

3. cache

   • why ?
     • The explanation is: a cache is a data storing technique that provides the ability to access data or files at a higher speed.
   • how ?
     • The data in a cache is generally stored in fast access hardware such as RAM (Random-access memory) and may also be used in correlation with a software component.
       • To store data locally in order to speed up subsequent retrievals. Pronounced "cash." See Web cache and browser cache.
   • what ?
     • Caching is a term used in computer science. ... Put differently, a cache is a temporary storage area that has copies of data that is used often.

4. cores

   • how ?
     • The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body.
   • why ?
     • Your brain is the CPU in your body. The CPU is the brain in the computer. The uses of the CPU are many and include performing calculations, running programs, and so on.
   • what ?
     • 1. A core, or CPU core, is the "brain" of a CPU. It receives instructions, and performs calculations, or operations, to satisfy those instructions. A CPU can have multiple cores.
       • A processor core (or simply “core”) is an individual processor within a CPU. Many computers today have multi-core processors, meaning the CPU contains more than one core.
