    • Hardware: Processors and CPUS
      Bridget Gioia
      Jasper Grassa
    • Hardware
      Tangible parts of computer systems, includes support for processing, storage, input, and output
    • Processing
      Carries out instructions given by software using circuitry and a defined routine to transform data into useful outputs.
    • Processors
      • Designed to excel in a specific type of activity.:
      • Computer graphics
      • General-purpose personal computing
      • Industrial use in mainframe computers
      • Special-purpose (media player, digital cameras, and medical equipment)
    • Integrated Circuit
      • Also called chips or microchips; connect transistors and other electronic components on a thin piece of material like silicon.
      • Store and process bits and bytes
    • Central Processing Unit (CPU)
      • A group of circuits that perform the processing in a computer, typically in one integrated circuit called a microprocessor.
      • The CPU governs all actions that a computer carries out
    • Control Unit
      • Accesses program instructions then decodes them.
      • After doing this they direct the flow of data in and out of the ALU, the registers, RAM, and other system components like secondary storage, input, and output devices.
    • Arithmetic/logic unit and Registers
      ALU contains the circuitry to process mathematical and logical operations.
      Registers holds the bytes being processed at the time.
    • Cache
      • A temporary storage place for frequently and recently accessed data.
      • Having certain data stored in a cache makes the operation of the computer faster
      • The size of cache is measured in megabytes (MB)
    • Clock Speed
      Speed of the processor: says how fast it can process data (measured in gigahertz (GHz)
    • Multiprocessing
      Uses more than one processing unit to increase productivity and performance
    • Multi Core Processor
      • Combines multiple CPUs on one chip to speed up processing
    • Moore’s Law
      Number of transistors on a chip will double every two years
    • Optical Computing
      Optical processors use light waves instead of electrical currents
      Have the potential to be 500x faster than electronic circuits
    • Three-Dimensional Processing
      Change 2D wafers to 3D arrays to speed up processing
      Allows processing to occur vertically and horizontally
    • Quantum Computing
      • Uses quantum bits (qubits) instead of bits
      • Displays properties of the laws of quantam mechanics rather than classical psychics
    • DNA Computing
      Computer would be composed of enzymes and DNA molecules
      Perform 330 trillion operations per second (100,000x the speed of PCs)
    • Motherboard
      • Primary circuit of a computer
      • All core components are connected here
    • Bus
      Subsystem on the motherboard that transfers data among the components
