CPU

  1. 1. CPU Computer Maintenance
  2. 2. What is a CPU? <ul><li>Often called the brains of the computer, the CPU is the device that performs the calculations that make computing possible. </li></ul>
  3. 3. Two typical components of a CPU: <ul><li>The arithmetic logic unit (ALU) , which performs arithmetic and logical operations. </li></ul><ul><li>The control unit (CU) , which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary. </li></ul>
  4. 4. CPU Terminology <ul><li>Front Side Bus (FSB): Measured in megahertz or gigahertz, the FSB is the channel that connects the processor with the main memory. </li></ul><ul><li>Multi-core: Composed of two or more independent CPUs in one chip. </li></ul><ul><li>Cache: Expensive high-speed memory used for storing frequently used instructions. </li></ul><ul><li>Sockets and slots: Processors either fit in a socket or slot, depending on their construction. </li></ul>
  5. 5. CPU Terminology (cont.) <ul><li>Pins: Within the categories of sockets and slots, there are different types of each. The types vary by size, and number and configuration of pins. </li></ul><ul><li>Fans and heatsinks: Heatsinks are little radiators used to radiate the heat away from the processor. Together with the fan they keep the processor’s temperature within a safe range. </li></ul><ul><li>CPU families: Each member of a family has the same internal design with the only difference being speed and perhaps some less-publicized specifications. </li></ul>
  6. 6. Selecting an Appropriate Processor <ul><li>Compatibility with the Motherboard </li></ul><ul><ul><li>Socket or Slot </li></ul></ul><ul><ul><li>Brand of processor </li></ul></ul><ul><ul><li>Certain models and speed </li></ul></ul><ul><li>Fastest with the most cache you can afford. </li></ul>
