The device that commands and coordinates the work of the computer is .

Controller. The controller is the part that directs the various parts of the computer to work in coordination according to the functional requirements of the instructions, and is the nerve center of the computer.

and the command center, which is registered by instructions.

IR (instructionregister), program counter.

The PC (ProgramCounter) and the operation controller 0c (OperationController) are composed of three parts, which are extremely important for coordinating the orderly work of the entire computer.

A computer system consists of two parts: a hardware system and a software system. The American-Hungarian scientist John Von Neumann laid the basic structure of the modern computer, which is characterized by:

1) Use a single processing component to complete the work of calculation, storage, and communication.

2) The storage cell is a linear organization of fixed length.

3) The unit of the storage space is directly addressed.

4) Using low-level machine language, instructions are used to complete simple operations through opcodes.

5) Centralized sequential control of calculations.

6) The computer hardware system consists of five components: combinator, memory, controller, input device, and output device, and stipulates their basic functions.

7) Color binary form represents data and instructions.

8) When executing programs and processing data, programs and data must be ethically loaded from the external memory into the main memory, so that the computer can automatically adjust the instructions from the memory and execute them when working.

The CPU (** processor) of the device that directs and coordinates the work of the computer.

**The processor is a very large-scale integrated circuit, which is the computing core and control core of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software.

**The processor mainly consists of combinators (Arithmetic Logic Unit, ALU) and cache memory and the buses that enable the data, control and state between them. Together with the internal memory and input-output (IO) devices, it is known as the three core components of an electronic computer.

Controller Controller Controller.

Answer]: B memory is a device that stores programs and data; The controller is the command center of the computer of the judgment family, which makes all parts of the computer work automatically and coordinatedly; Combinators are components that perform calculations on data; Registers are storage units in the CPU, high-speed storage components with limited storage capacity, which can be used to temporarily store finger orders, data, and addresses. Keijo hood.

The device that directs the work of the Burning Rock coordination computer is the CPU (** processor).

The CPU is the part that commands the various parts of the computer to coordinate and work according to the functional requirements of the instructions, and is the nerve center or center and command center of the computer, and the CPU is the computing and control core of the computer system, and is the final execution unit of information processing and program operation. Since its inception, the CPU has made tremendous progress in terms of logical structure, operational efficiency, and functional extension.

In computer architecture, the CPU is the core hardware unit that controls and allocates all the hardware resources of the computer (such as memory, input and output units) and performs general-purpose operations. The operations of all software layers in a computer system will eventually be mapped to the operations of the CPU through the instruction set.

CPU function

**The processor (CPU) is one of the main equipment of the electronic computer and the core component in the computer. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is the core component of the computer that is responsible for reading, decoding and executing instructions.

**The processor mainly consists of two parts, namely the controller and the combinator, which also includes the cache memory and the data and control of the data that are connected between them. The three core components of an electronic computer are the CPU, internal memory, and input and output devices. **The functions of the processor are mainly to process instructions, perform operations, control time, and process data.

Answer]: The main function of the controller is to command the automatic and coordinated work of all parts of the machine.
