==Computing==
=== Hardware === 
* [[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
**** [[Neural processing unit]] (NPU), a class of specialized [[Hardware acceleration|hardware accelerator]] or computer system designed to accelerate [[artificial intelligence]] and [[machine learning]] applications, including [[Artificial neural network|artificial neural networks]] and [[machine vision]]
**** [[Vision processing unit]] (VPU), an emerging ({{as of|2023|lc=y}}) class of [[microprocessor]]; it is a specific type of [[AI accelerator]], designed to [[Hardware acceleration|accelerate]] [[machine vision]] tasks
**** [[Tensor Processing Unit]] (TPU), an [[AI accelerator]] [[application-specific integrated circuit]] (ASIC) developed by [[Google]] for [[Artificial neural network|neural network]] [[machine learning]], using Google's own [[TensorFlow]] software.
**** [[Secure cryptoprocessor]]
**** [[Quantum processor]], a [[computer]] that takes advantage of [[Quantum mechanics|quantum mechanical]] phenomena. At small scales, physical matter exhibits properties of [[wave–particle duality|both particles and waves]], and quantum computing leverages this behavior, specifically quantum superposition and entanglement, using specialized hardware that supports the preparation and manipulation of [[quantum state]]s.
**** [[Coprocessor]]
**** [[Floating-point unit]]
**** [[Audio processor]]
**** [[Network processor]], a microprocessor specifically targeted at the networking application domain
**** [[Baseband processor]]
** [[Multi-core processor]], single component with two or more independent CPUs (called "cores") on the same chip carrier or on the same die
** [[System on a chip]], a chip including one or more processor cores, such as CPUs, GPUs and others, and additional support circuitry
** [[Front-end processor]], a helper processor for communication between a host computer and other devices

=== Software ===
* [[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 ===
* [[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

== Other ==
* [[Firewood processor]], a machine designed to cut and split firewood
* [[Food processor]], an appliance used to facilitate repetitive tasks in the preparation of food
