  • 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
