    en.wikipedia.org/wiki/Machine_code

    In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers , machine code is the binary representation of a computer program which is actually read and interpreted by the computer.

    A modern consumer CPU made by Intel: An Intel Core i9-14900KF Inside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006. A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer.

  4. Microcode - Wikipedia

    en.wikipedia.org/wiki/Microcode

    The advantage over a hard-wired CPU is that internal CPU control becomes a specialized form of a computer program. Microcode thus transforms a complex electronic design challenge (the control of a CPU) into a less complex programming challenge.

  5. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.

    A computer language is a formal language used to communicate with a computer. Types of computer languages include: Construction language – all forms of communication by which a human can specify an executable problem solution to a computer. Command language – a language used to control the tasks of the computer itself, such as starting programs

  7. Control unit - Wikipedia

    en.wikipedia.org/wiki/Control_unit

    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.).
