What are the main uses of the following hardware?

The question is incomplete, what hardware is there?

You can directly touch and see the electronic products that can be controlled by software can be called hardware, such as the composition of PC: monitor, hard disk, CPU, motherboard. or other equipment.

(1) At present, the conventional desktop computer, a complete set, mainly includes the following 11 components:

CPU (Loose CPU is not sent back.)

Radiator, boxed CPU comes with radiator) A.

CPU radiator (if you buy a "boxed CPU", you will give a CPU radiator, but the radiator with a small diameter and high speed and high noise will be given away).

Motherboard memory module.

Hard disks (currently divided into mechanical hard disks and solid state drives).

Power supply chassis (you can learn about the mid-tower chassis and mini chassis) discrete graphics card (if the front CPU is an APU and CPU integrated core graphics card, then you can not buy a discrete graphics card).

Display. Keyboard and mouse cover.

Headphones or speakers (you can choose one or the other, or both, and the headphones will not cause discomfort when worn for a long time).

2) The hardware layout of the computer host is as follows:

Hardware facilities include plants, machines, appliances, production lines, office equipment, etc., in addition to the program in your unit's computer and the control system of the production equipment is software, other production-related things are hardware facilities.

The hardware system of a computer network usually consists of five parts: a file server, a workstation (including terminals), a transmission medium, network connection hardware, and external devices.

1. Introduction to file servers.

The file server is generally required to be equipped with a microcomputer with a high-performance CPU system, which acts as the core of the network. In addition to managing transactions across the network, it must provide a variety of resources and services.

2. Introduction of transmission medium.

The transmission medium is the physical path between the sender and receiver in the communication network, and in the case of the local area network, the cable used to connect the server and the workstation. At present, the commonly used network transmission media include twisted pair (mostly used in local area network), coaxial cable and optical cable.

3. Introduction of workstations.

The workstation can be said to be a kind of intelligent terminal, which can process the program and data from the file server after it is processed on the site, generally with and without disk.

4. Introduction of network connection hardware and external devices.

Commonly used network connection hardware includes network interface cards (NICs), hubs, repeaters, and modems. Printers, scanners, plotters, and anything else that can be shared by a workstation can be called an external device.

Hardware: The hardware system is mainly composed of processors, memory, input and output control systems and various external devices.

**The processor is the main component of high-speed computing and processing of information, and its processing speed can reach more than hundreds of millions of operations per second.

Memory is used to store programs, data, and files, and is often composed of fast internal memory (with a capacity of hundreds of megabytes, or even several gigabytes of sensitivity) and slow massive external memory (with a capacity of tens of gigabytes or hundreds of gigabytes or more).

Various input and output peripherals are bridge information converters between man and machine, and the input-output control system manages the information exchange between the external devices and the main memory (** processor).

Computer hardware is an important part of a computer, which contains five important components: combinator, controller, memory, input device, and output device.

1. Combinator.

The main function of combinators in computer hardware is to perform calculations and processes data and information. Combinators consist of the following parts: general registers, state registers, accumulators, and key arithmetic logic units.

Combinators can perform arithmetic calculations (addition, subtraction, multiplication and division) and logical operations (AND or NOT).

2. a controller.

Together, the controller and combinator make up the CPU (CPU). The controller can be regarded as the brain and command center of the computer, which can make the various components of the computer complete the instructions in an orderly manner by integrating and analyzing relevant data and information.

3. Memory.

As the name suggests, memory is the memory system of a computer, which is the notepad in a computer system. Unlike notepads, memory can not only store information, but also accept and read different information in a computer system. The memory is composed of the main memory and the auxiliary memory, the main memory is commonly referred to as memory, which is divided into two parts: RAM and ROM.

Auxiliary memory is external memory, but when the computer processes the information stored externally, it must first go through the information exchange between the internal and external memory before it can be carried out.

4. Input device.

Both input and output devices are critical to human-machine interaction. The advent of input devices such as mice and keyboards has brought earth-shaking changes to computers. There are two main types of existing mice:

Optical mice and mechanical mice. Through the mouse, we can easily locate the coordinates on the computer screen, and can operate the graphics and software processing well, providing the greatest convenience for human beings. The keyboard is also a very important input device, and most of the computer's instructions are carried out through the keyboard.

5. an output device.

The output device is also the key equipment of computer human-computer interaction, which is characterized by the fact that the information of the computer can be displayed in the form of a picture, which has a good intuitiveness. Common output devices include monitors, printers, voice and output devices.

Hardware, software, and facilities are commonly used terms in the field of information technology to refer to different aspects of technology and equipment.

1.Hardware refers to physical components: Hardware refers to electronic, mechanical, or other physical entities that are used to build computer systems or other electronic devices. This includes the computer's main unit, monitor, keyboard, mouse, storage device, processor, chip, printer, etc.

2.Software refers to programs and applications: Software refers to a collection of instructions executed by a computer that controls hardware and makes it perform a specific task.

Software can include operating systems, applications, and other computer programs that are used to accomplish various functions such as word processing, data analysis, graphic design, etc.

3.A facility is a support facility or structure: A facility is an infrastructure, equipment or resource that provides support for a specific purpose or task.

In the field of information technology, facilities can refer to data centers, server rooms, network equipment, communication lines, and air-conditioning systems in computer rooms. These facilities provide the necessary environment and support for both hardware and software.

In a complete information technology environment, hardware provides the physical basis for computing and data storage, software is used to control hardware and provide various functions and services, and facilities provide support and guarantee the operation of hardware and software. These three aspects are interdependent and together constitute a complete technical system.

For individual users, hardware can be computers, mobile phones, and other personal electronic devices, software can be various applications and poor operating systems, and facilities can be network connections and network infrastructure. For businesses and organizations, hardware, software, and facilities can be much larger and more diverse in size and complexity. <>
