A CPU, or central processing unit, is a vital part of your computer or phone, and is responsible for executing every command you or an app makes.
Ulric Neisser coined the term cognitive psychology in his book with that title published in 1967. Neisser characterizes people as dynamic information-processing systems whose mental operations might be described in computational terms. Steven Pinker described language instinct as an evolved, built-in capacity to learn language (if not writing).
According to the Atkinson-Shiffrin memory model or multi-store model, for information to be firmly implanted in memory it must pass through three stages of mental processing: sensory memory, short-term memory, and long-term memory. [7] An example of this is the working memory model.
A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core , which stores copies of the data from frequently used main memory locations .
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
The term is frequently used to refer to the central processing unit (CPU), the main processor in a system. [7] However, it can also refer to other coprocessors , such as a graphics processing unit (GPU).

The "ghost in the machine" is a term originally used to describe and critique the concept of the mind existing alongside and separate from the body.In more recent times, the term has several uses, including the concept that the intellectual part of the human mind is influenced by emotions; and within fiction, for an emergent consciousness residing in a computer.
