• CPU


  Central Processing Unit, sits on the motherboard, responsible for processing and manipulating data
• CPU


  • Produces a lot of heat, requires a dedicated heatsink fan to cool it down
• Processor


  General term that can refer to the CPU or other processing components like graphics cards and sound cards
• CPU components


  • ALU (Arithmetic Logic Unit) - performs processing operations
  • Control Unit - coordinates the CPU and controls the computer
  • Register Unit - small, quick storage locations on the CPU
• Von Neumann architecture


  The standard architecture for modern computers, consisting of memory, control unit, processing unit, and input/output devices
• Stored program concept


  Instructions and data are stored together in memory
• Harvard architecture


  An alternative architecture with separate memories for instructions and data, not used in modern computers
• Fetch-Execute Cycle


  1. Fetch instruction from memory

  2. Decode instruction into operator and operands

  3. Execute instruction using ALU and registers
• System clock


  Provides timing signals to synchronize the operation of computer circuits
• Clock speed


  The frequency at which the CPU operates, determines how fast it can execute instructions
• The faster the clock speed, the faster the CPU can execute instructions
