WHAT IS PROCESSOR ?

• Processor (computing)
  • Central processing unit (CPU), the hardware within a computer that executes a program
    • Microprocessor, a central processing unit contained on a single integrated circuit (IC)
      • Application-specific instruction set processor (ASIP), a component used in system-on-a-chip design
      • Graphics processing unit (GPU), a processor designed for doing dedicated graphics-rendering computations
      • Physics processing unit (PPU), a dedicated microprocessor designed to handle the calculations of physics
      • Digital signal processor (DSP), a specialized microprocessor designed specifically for digital signal processing
        • Image processor, a specialized DSP used for image processing in digital cameras, mobile phones or other devices
      • Coprocessor
      • Floating-point unit
      • Network processor, a microprocessor specifically targeted at the networking application domain
  • Multi-core processor, single component with two or more independent CPUs (called "cores") on the same chip carrier or on the same die
  • Front-end processor, a helper processor for communication between a host computer and other devices

Software[edit]

• Word processor, a computer application used for the production of potentially printable material
• Document processor, a computer application that superficially resembles a word processor—but emphasizes the visual layout of the document's components

Systems[edit]

• Information processor, a system which takes information in one form and transforms it into another form by an algorithmic process
• Data processing system, a combination of machines, people, and processes that for a set of inputs produces a defined set of outputs
• Information system, a system composed of people and computers that processes or interprets information
