What parts are there in the computer host, and what are the functions of each part?

What parts are there in the computer host, and what are the functions of each part?

CPU (processor)--the core component that processes various data

Power supply--provides power for the entire computer. There is a power fan outside the power supply to cool the power supply

Motherboard - carries various devices (such as CPU, memory, etc.) and provides channels for mutual communication

Memory - a place where data is temporarily stored when executing programs

Hard disk - a storage device for storing programs, pictures and other data

Graphics card - a device that provides display functions for programs etc.

Sound card - a device that provides sound for the system

Optical disc drive - a device that reads the data in the optical disc (if it is a CD-ROM burner, it can also perform writing operations)

Network card - used for Internet access (with The motherboard has an integrated network card), and some older machines also have a built-in Modem, which is used when dialing up the Internet via telephone. It is rarely used now

Floppy disk drive--older The computer also has a floppy disk drive, a device that reads 3.5-inch floppy disks

CPU fan--cools the CPU radiator

The motherboard usually also has various interfaces. One to two nine-pin serial ports, one fifteen-pin parallel port, one twenty-five-pin parallel port (this port is commonly used in printers, but many printers now have USB ports), two to six USB ports, If the sound card and graphics card are integrated, there will also be a CRT monitor interface and three sound card interfaces. A general motherboard will have PCI slots, AGP slots, IDE slots, and floppy disk slots, among which AGP It is for plugging in external AGP display cards. PCI can be plugged into external network cards, modems, TV cards and other devices. The IDE slot is connected to IDE hard disks and IDE CD-ROM drives. The floppy disk drive is naturally connected to the floppy disk drive. IDE generally has Two, one floppy disk slot, and usually one AGP slot. PCI depends on the motherboard brand and model, usually 2-6 slots.

Nowadays, new dual-core motherboards also have SATA slots. slots and PCI-E slots. The SATA slot is connected to SATA hard drives and CD-ROM drives that transmit data faster. PCI-E is connected to the graphics card. In addition, there are memory slots, usually 1 to 4. For plugging in memory, the general specifications include early SDRAM, DDR, and the new and commonly used DDRII. However, DDR and DDRII coexist now, and there is still a large market for DDR. What is the relationship between the various components of the computer host that will gradually withdraw from the computer market?

The motherboard you buy must be of the same model as the CPU and memory. Others do not ask what the functions of each component of the computer host are.

What are the basic components of the computer host? , what are the functions of various components? Monitor, motherboard, memory, hard disk, CPU, graphics card, optical disk drive, floppy disk drive, chassis power supply, keyboard, mouse. In detail: 1 Hardware system: The computer hardware system consists of input devices, host and output device. External information is input into the host through the input device, analyzed, processed, and processed by the host, and then output through the output device. #1 Input and output device: Computers can only recognize binary digital electrical signals, while people are accustomed to receiving graphic, text, audio and video signals. Input and output devices play the role of signal conversion and transmission. We commonly use keyboards to input text, microphones to input sounds, and digital cameras, scanners, and cameras to input images. Commonly used output devices include monitors, printers and speakers. #1 Motherboard: Also known as the motherboard, it is a rectangular circuit board installed in the host chassis, with the main circuit system of the computer installed on it. The type and grade of the motherboard determines the type and grade of the entire microcomputer system, and the performance of the motherboard affects the performance of the entire microcomputer system. The motherboard is equipped with control chipset, BIOS chip and various input and output interfaces, keyboard and panel control switch interfaces, indicator light connectors, expansion slots and DC power supply plug-in and other components. The CPU and memory strips are plugged into the corresponding slots (seats) of the motherboard, and hardware such as drives and power supplies are connected to the motherboard. The interface expansion slot on the motherboard is used to plug in various interface cards, which expand the functions of the computer. Common interface cards include graphics cards, sound effects cards, etc. #1 CPU: The CPU (Central Processing Unit) is the core of the computer. The computer's ability and speed to process data mainly depends on the CPU. The capability and speed of the CPU are usually evaluated by bit length and main frequency. For example, the PII300 CPU can process binary data with a bit length of 32 bits and the main frequency is 300MHz. #1 System Bus: The system bus is the information path that connects the expansion slots. ISA and PCI buses are currently commonly used system buses in PCs, and there are corresponding ISA and PCI slots on the motherboard. #1 Input-output interface: I/O interface for short, is the interface that connects the motherboard and input-output devices. The serial port, parallel port, keyboard interface, PS/2 interface, USB interface on the back of the host, as well as the hard disk and floppy disk interfaces inside the host are all input and output interfaces.

#1 Serial communication interface (RS-232-C): Serial port for short, is a standard interface for transmitting information between computers and other devices. Current computers have at least two serial ports, COM1 and COM2. #1 Parallel communication interface: Parallel port for short, is a standard interface for transmitting information between computers and other devices. This interface transmits 8 data bits in parallel at the same time. The parallel port data transmission speed is faster than the serial port, but the transmission distance is shorter. . The parallel port uses a 25-hole D-shaped connector, which is often used to connect printers. #1 EIDE interface: Also called expansion kit IDE interface, it is the interface for connecting EIDE devices on the motherboard. Common EIDE devices include hard drives and optical drives. Currently, the newer interface standards include Ultra DMA/33 and Ultra DMA/66. #1 AGP: "Accelerated Graphics Port" is a graphics card interface standard proposed by Intel in July 1996. AGP graphics cards are connected through the AGP slot on the motherboard. The transmission speed of the PCI bus can only reach 132MB/s, while the AGP port can reach 528MB/s, which is four times the transmission speed of the former. AGP technology has greatly improved the performance of graphics display (especially 3D graphics), making PCs a big step forward in graphics processing technology. #1 Optical Disc Drive: A device that reads optical disc information. It is an indispensable hardware configuration for multimedia computers. Optical discs have a large storage capacity, are cheap, and have a long storage time. They are suitable for storing large amounts of data, such as sound, images, animations, video information, movies and other multimedia information. There are three types of optical disc drives, CD-ROM, CD-R and MO. CD-ROM is a read-only optical disc drive; CD-R can only be written once and cannot be rewritten later; MO is a writable and readable optical disc drive. #1 Memory storage: Memory, for short, is a semiconductor chip used to store current information to be processed and commonly used information. The capacity is not large, but the access is fast. Memory includes RAM, ROM and Cache. #1 RAM: RAM (Random Access Memory) is the main storage of the computer. People are accustomed to calling RAM memory. The biggest feature of RAM is that data will be lost when it is shut down or powered off. A computer with larger memory can process a larger amount of information at the same time. We use refresh time to evaluate the performance of RAM, the unit is ns (nanoseconds). The smaller the refresh time, the faster the access speed. Commonly used RAMs in 586 computers include EDO RAM and SDRAM. The memory chips are installed on finger-width strip circuit boards, called memory strips. The memory module is installed in the memory module slot on the motherboard. According to the connection method between the memory strip and the motherboard, there are 30 lines, 72 lines and 168 lines. Currently installed SDRAM memory sticks with 168 lines, a refresh time of 10ns, and a capacity of 32M (or 64M) are commonly used. #1 Cache: Cache (cache memory) is a small-capacity but high-speed storage located between the CPU and the main memory. Since the speed of the CPU is much higher than that of the main memory, the CPU has to wait for a certain period of time to directly access data from the memory. The Cache stores a part of the data that the CPU has just used or recycled. When the CPU uses this part of the data again It can be called directly from the Cache, which reduces the waiting time of the CPU and improves the efficiency of the system. Cache is divided into first-level Cache (L1 Cache) and second-level Cache (L2 Cache). L1 Cache is integrated inside the CPU, and L2 Cache is usually welded on the motherboard. Common motherboards have 256KB or 512KB L2 Cache welded on them. #1 ROM: ROM (read-only memory) is a semiconductor chip that stores computer instructions and data. However, data can only be read from it but cannot be written to it. The data in the ROM will not be lost after the computer is shut down or powered off. Manufacturers store some important information and programs in ROM that are not allowed to be changed by users, such as the BIOS program stored in the ROM of the motherboard and graphics card. #1 BIOS: BIOS is a program, which is the basic input and output system of a microcomputer. The main function of the BIOS program is to manage the computer hardware. The BIOS program is the first program that is executed when the computer is turned on. After booting, the BIOS program first detects the hardware, initializes the system, then starts the drive, reads the operating system boot record, and hands over system control to the disk boot record, which completes system startup. When the computer is executing, the BIOS also cooperates with the operating system and software to operate the hardware. The BIOS program is stored in the ROM BIOS chip on the motherboard. Currently, most 586 motherboards use Flash ROM to store BIOS programs. The programs (data) in Flash ROM can be updated by executing the program. #1 CMOS: CMOS is a readable and writable RAM chip on the motherboard, which is used to store the current system's hardware configuration information and certain parameters set by the user. CMOS RAM is powered by the battery on the motherboard, and information will not be lost even if the system loses power. Setting and updating various parameters in CMOS requires executing a special setup program. When booting, you can enter the BIOS setup program by pressing a specific key (usually the Del key) to set the CMOS.

CMOS settings are also traditionally called BIOS settings. #1 Graphics card: Also known as a monitor adapter card, it is an interface card that connects the host and monitor. Its function is to convert the output information of the host into information such as characters, graphics, and colors, and transmit it to the monitor for display. The graphics card is inserted into the ISA, PCI, and AGP expansion kit slots of the motherboard. ISA graphics cards have been basically eliminated. #1 Sound Card: An interface card used in multimedia computers to process sound. The sound card can convert speech, music and other sounds from microphones, cassette recorders, CD players and other devices into digital signals for computer processing and save them in file form. It can also restore digital signals to real sound output. The interface at the end of the sound card protrudes from the back of the chassis, and has interfaces for connecting microphones, speakers, joysticks, and MIDI devices. #1 Video capture card: An interface card used to capture dynamic or static video images input from TV antennas, video recorders, DVD players, etc. It is an important tool for multimedia production. High-end video capture cards can also perform MPEG compression and create VCD while capturing images. #1 Interrupts: An interrupt is a process by which a computer handles a special problem. When a special situation (or "event") occurs while the computer is executing the program, the current program is temporarily suspended, and the program that executes the event is transferred to the program that executes the event. After the processing is completed, it returns to the interruption point of the original program to continue. The entire process of execution is called an interrupt. #1 IRQ: That is, "interrupt request", which is a signal sent by other devices requesting a computer response. The computer will decide when to respond based on the level and priority of the IRQ. In principle, each device has its own unique interrupt request channel, that is, IRQ value (also called IRQ number). If two hardware devices use the same interrupt channel, an IRQ conflict will definitely occur. #1 DMA: That is, "direct memory access", which is a data transfer operation within the computer. The entire data transfer operation process is carried out under the control of the "DMA controller" and does not pass through the CPU. During the data transmission process, the CPU only performs a little processing at the beginning and end of the data transmission. DMA technology greatly improves the efficiency of computer systems. DMA transmission is performed through DMA channels. For example, floppy disk drives and sound cards all occupy DMA channels to transmit data. Two devices cannot use the same DMA channel to transmit data at the same time, otherwise a DMA conflict will occur. #1 Main frequency and FSB: Main frequency refers to the CPU core operating clock frequency. FSB refers to the working clock frequency of the CPU and the external (motherboard chipset) for exchanging data and instructions. The system clock is the "external frequency" of the CPU. The clock signal obtained by multiplying the system clock according to a specified ratio is used as the core working clock (main frequency) of the CPU. For example, if a computer uses a Pentium 233 CPU, the FSB of this computer is 66MHz, and its main frequency is (66×3.5) = 233MHz. The system clock (FSB) is the basic clock of the computer system. All clocks of different frequencies in each subsystem of the computer are associated with the system clock. For example, in the current 100 MHz FSB system, the system memory works at 100 MHz (or 66 MHz), L2 Cache works at 100 MHz, PCI works at 33 MHz, and AGP works at 66 MHz. It can be seen that the above frequencies have a certain proportional relationship with the external frequency. Increasing the system clock (FSB) can improve the performance of the entire computer, but increasing the FSB will inevitably change the clock frequencies of other subsystems and affect the actual execution of each subsystem. This should be paid full attention to when the CPU exceeds the FSB. . #1 DVD: Digital Versatile Disc. A DVD drive refers to a device that reads DVD discs. The capacity of a DVD disc is 4.7GB, which is equivalent to seven times that of a CD-ROM disc. It can store a 133-minute movie and includes seven Dolby Digital surround sound tracks. DVD discs can be divided into: DVD-ROM, DVD-R (can be written once), DVD-RAM (can be written multiple times) and DVD-RW (read and rewrite). Most current DVD players use the EIDE interface, which can be connected to the IDE1 or IDE2 port like a CD-ROM player. What are the functions of the various parts of the erhu?

The structure of the erhu is relatively simple, consisting of the piano tube, the piano rod, the piano skin, the pegs, the strings, the bow rod, the jack, the bridge and the bow hair. The functions of each part of the Erhu:

The Erhu is composed of nine main parts, and their functions are introduced as follows:

A Qintong: It is an important part of the Erhu, which is pushed and pulled by the bow. Movement, the sound body that vibrates the piano skin after wiping the strings. The texture and shape of the piano barrel have a direct impact on the volume and sound quality. Generally made of rosewood or mahogany. The shapes include hexagon, octagon, circle, front octagon and back circle, etc. The most commonly used is hexagon. There is a sound window (usually a carved wood window) inlaid behind the piano tube, which not only decorates the piano tube, but also has certain benefits for pronunciation, sound transmission and sound filtering.

B piano skin: There are two types: python skin and snake skin that can be moved up or down. Python skin is better. It is an important pronunciation body of Erhu and the key to the vibration source. It has a direct impact on the sound quality and volume. The bigger the scales of the frog, the better the sound.

C piano pole: It is the pillar and trunk of the erhu. It not only plays a supporting role in connecting the upper and lower parts, but also has a certain influence on the overall vibration and pronunciation.

Some materials for making piano rods include sandalwood, ebony or mahogany. Generally, more mahogany is used. Redwood is cheap, high-quality, and has certain tensile properties.

D piano shaft: There are two upper and lower piano shafts (also known as Qin Zhen), which play the role of adjusting the pitch. The upper shaft is bound with rubber inner strings, and the lower shaft is bound with twisted outer strings. There are two types of piano shafts: wooden shafts and mechanical shafts, both of which have their own pros and cons. The wooden shaft is stable after tuning and will not easily go out of tune. However, it is sometimes tight and loose, which makes tuning difficult. The mechanical axis tunes the strings quickly and freely, and the intonation is good, but the current production quality is not completely satisfactory, and sometimes looseness and slipping occur, which can easily lead to out-of-tune strings.

Types of piano shafts: copper and wooden zither

E bow: It is an important tool for erhu pronunciation. It consists of two parts: bow rod and bow hair. The bow shaft is made of thin and solid purple bamboo and should be of moderate thickness. The softness, hardness and elasticity of the bow rod will directly affect the performance. In the past, nylon silk and horse hair were used for bow hair. Horsetail was mostly used, and white horsetail was the best, followed by black horsetail. Generally, thin purple bamboo is used to tie the ponytail, and a live screw (bow fish) is installed at one end to adjust the tightness of the bow hair. F string: It is one of the sounding bodies of the piano and one of the sound sources of the erhu. Its quality directly affects the pronunciation effect. There are currently two types of strings: one is metal strings, which have the characteristics of good tension, good sound quality, good intonation and high sensitivity. They are divided into aluminum strings and silver strings. Silver strings are the best; the other is silk strings. , the sound it produces is softer and more delicate than metal strings, but it has poor positional force, poor intonation, and is easy to break the strings and change the sound. Nowadays, metal strings are mostly used.

G Qianjin: Also known as Qianjin, it plays a role in fixing and cutting the erhu strings. It also has a certain impact on pitch. It is made of cotton thread, silk thread, plexiglass, plastic and other materials. There are various forms, including fixed jacks, wire-wound jacks, metal jacks, etc. The more commonly used one is Hongrao Qiandujin.

H bridge: It is the vibrating medium between the strings and the piano skin, and plays an important role in pronunciation. The materials used include wood, bamboo, metal, paper, etc. Commonly used materials include pine knotted horses and maple wooden horses. The wood of the pine knot horse is soft, and the pronunciation is round and honest. The maple horse is moderately soft and hard, with a soft pronunciation and less noise. J piano base: It is the bottom bracket of the piano body, which plays the role of decoration and stabilization of the piano body. Some erhu piano supports are also equipped with adjustable bottom supports, which can be adjusted with nylon buckles, making it more convenient when playing. What components does a computer host consist of? What are the functions of these components?

It is divided into two parts: 1. The motherboard (the motherboard is equivalent to a platform, mainly including pcb circuit boards, and various Interface, slot, chip) 2 Interface component Slot component is referred to as plug-in (including CPU, memory, graphics card, multi-function card, hard disk, power supply, etc.).

Component function: CPU (core , for calculation), memory (temporarily store data), motherboard (connect CPU, memory, graphics card, hard disk, etc.), graphics card (compute graphics, display output), hard disk (save system, data) (use), power supply (power supply), etc.

What are the parts of the computer?

1. CPU (Central Processing Unit), the CPU includes arithmetic units and internal storage cache (now called a cache). It is the main core of the computer and is responsible for computing and processing all data.

2. RAM (memory), all data that needs to be processed by the CPU must be temporarily stored in the memory. Its size is closely related to the execution speed of the entire machine. Although it is called memory, But it will release all storage space when the power is turned off.

3. The hard disk is the real storage of the computer. All data is stored in it. The computer has data processing, which is to send data from the hard disk to the memory and then process it by the CPU, so It is not directly connected to the CPU. The data stored in it will never be lost unless you delete it or the hard drive fails.

4. The motherboard is another main accessory of the computer. All the accessories in the computer are connected to the motherboard, including the north and south bridge chips and CMOS batteries, so it is a platform and bridge. Failure is crucial to the performance of the entire machine.

5. The graphics card, hence the name, means that only graphics on the computer can be displayed on the monitor. Its quality is directly related to the graphics display effect of the computer.

6. Sound card, with which the computer can have pleasant sound. Of course, there is a small speaker on the chassis. Without a sound card, the small speaker can also make some basic alarm sounds, but without a sound card The computer is like a mute who can only babble.

7. CD-ROM (Compact Disc Drive), hardware used to read data from optical discs.

8. Floppy disk drive. Before the advent of optical discs, this task was performed by floppy disks. There were 5-inch and 3.5-inch floppy disks. Nowadays, ordinary computers no longer use this hardware because of the There is too little storage. The largest one is only 1.44M.

9. Chassis and power supply. Of course, power supply is an indispensable thing. In the machine age, there is no need to talk about anything else if there is no power. A good power supply can make the computer run more stably. As for the chassis, it only fixes various components. In terms of hardware and aesthetics, it’s okay to have it or not. Hardcore gamers don’t like to use a chassis because it hinders heat dissipation.

10. Monitor, the carrier of computer graphics display, can’t say more. Without monitors, computers would not develop and become popular so quickly.

11. Keyboard and mouse are the most basic input devices. The birth of the mouse also played an important role in the popularization of computers.

12. Network card or wireless network card. How can we travel in the online world without a network card in today's E era?

13. Speakers or headphones, how can you listen to sound without them?

At present, ordinary computers include the above 13 items. Of course, in addition to these, there are also some computer peripheral products, such as printers, scanners, mobile hard drives, TV cards, fault cards, cameras, etc. What parts are inside the computer host?

There is a motherboard, CPU, memory, graphics card, sound card, network card, hard disk, optical disk drive, and floppy disk drive.

Central Processing Unit (Central Processing Unit, CPU for short) is also called a microprocessor , it is a device that integrates arithmetic units and controllers on a semiconductor chip. It is the core of the microcomputer. Today's CPUs also integrate cache memory (Cache) to increase the speed of data processing.

The CPU is divided into 8-bit, 16-bit, 32-bit and 64-bit according to the word length of the information processed. Today's CPUs are mostly 32-bit and 64-bit, such as Intel's Pentium, Pentium II and Pentium III, AMD's K6, K6-2 and Athlon, etc.

CPUs are divided into operating frequencies: 300MHz, 333MHz, 400MHz, 466MHz, 500MHz, 550MHz, 600MHz, 800MHz and even 1GHz.

The motherboard, also known as the system board or motherboard, is the largest integrated circuit board in the microcomputer and the most important component. It includes the basic I/O interface, interrupt controller, DMA controller and buses for connecting other components, as well as the microprocessor module (CPU) and memory module installed on it.

Memory storage, referred to as memory, is the memory device of a computer. Its function is to store original data, intermediate data, calculation results and problem-solving programs. Storage usually accesses data and programs by address. It consists of many storage units, each unit stores a number of binary data codes. In order to distinguish different storage units, the storage units are numbered in a certain sequence. This number is called an address. To perform data access operations, you should first specify the address of the storage unit, and then "select" the corresponding storage unit according to the specified address by the memory to access data

Among the various parts of the computer There are three types of signals transmitted between devices: data, address and control signals. The line that transmits data signals is called data bus DB (Data Bus), the line that transmits address signals is called address bus AB (Address Bus), and the line that transmits control signals is called control bus CB (Control Bus). These three buses connect the five major parts of the computer. The bus is like a "highway", and the information transmitted on the bus is regarded as a "vehicle" on the highway. It is obvious that the number of "vehicles" passing on the highway per unit time is directly dependent on the width and quality of the highway. Therefore, bus technology has become an important aspect of microcomputer system structure. What are the components of computer hardware and what are the functions of each component?

1. Controller The controller is a component that analyzes the input instructions and uniformly controls each component of the computer to complete certain tasks. It generally consists of an instruction register, a status register, an instruction decoder, a sequential circuit and a control circuit. It is a component that coordinates and directs the work of various components of the computer. Its function is to sequentially retrieve commands from the memory, generate control signals, issue instructions to other components, and direct the entire computing process. The controller is the center for unified command and coordination of other components.

2. Calculator Calculator, also known as Arithmetic Logic Unit (ALU for short), is a component that performs arithmetic and logical operations. The main function of the arithmetic unit is to perform various arithmetic operations and logical operations and process data. Controllers, arithmetic units and temporary registers form the core of the hardware system - the Central Processing Unit (Central Processing Unit, referred to as CPU). The CPU is integrated on a chip using large-scale integrated circuit technology and is the core device of the computer system.

3. Storage Storage is a component of a computer that stores or temporarily stores data. All information in a computer, including raw input data. The intermediate data that has been initially processed and the useful information that has been finally processed are stored in the storage. Moreover, various programs that command the execution of the computer, that is, a series of instructions that specify how to process the input data, are also stored in the memory. Storage is divided into memory storage (referred to as memory or main memory) and external storage (referred to as external storage or auxiliary storage, such as a hard disk). Memory storage

External storage

4. Input device The input device is an important human-machine interface, used to accept the raw data and programs input by the user and convert them into It is converted into a binary system that can be recognized by the computer and stored in the memory. Commonly used input devices include keyboards, mice, scanners, light pens, etc.

Keyboard

Mouse

Scanner

5. Output device The output device is a device that outputs the results of computer processing and is used to The results of computer processing stored in the memory are converted into output in a form acceptable to people. Commonly used output devices include monitors, printers, plotters, etc.

Monitor

Printer What are the main components of an airplane? What is the function of each part?

1. The principle of airplane flight

An airplane is a heavier-than-air aircraft. When an airplane flies in the air, aerodynamic force will be generated on the airplane. The airplane relies on aerodynamic force to lift. Flying empty.

2. The main components and functions of flight

So far, except for a few special forms of aircraft, most aircraft are composed of wings, fuselage, tail, and landing gear. and the power unit consists of five main parts.

1. Wing - The main function of the wing is to generate lift to support the aircraft flying in the air, and also plays a certain role in stability and operation. Ailerons and flaps are generally installed on the wings. Operating the ailerons can make the aircraft roll, and lowering the flaps can increase lift. Engines, landing gear and fuel tanks can also be installed on the wings. Aircrafts with different uses also have different wing shapes and sizes.

2. Fuselage - The main function of the fuselage is to load passengers, passengers, weapons, cargo and various devices, and to connect other parts of the aircraft such as wings, tails and engines into one overall.

3. Tail - The tail includes horizontal tail and vertical tail. The horizontal tail consists of a fixed horizontal stabilizer and a movable elevator. Some high-speed aircraft combine the horizontal stabilizer and the elevator into a fully moving horizontal tail. The vertical stabilizer consists of a fixed vertical stabilizer and a movable rudder. The function of the tail is to control the pitch and deflection of the aircraft to ensure that the aircraft can fly smoothly.

4. Landing gear - The landing gear of an aircraft is mostly composed of shock absorbing struts and wheels. Its function is to support the aircraft during takeoff and landing, taxiing on the ground and parking.

5. Power unit - The power unit is mainly used to generate pulling force and thrust to make the aircraft move forward. Secondly, it can also provide power for other electrical devices on the aircraft. Nowadays, the most widely used aircraft power plants include: aviation piston engines plus propellers, turbojet engines, turboprop engines and turbofan engines. In addition to the engine itself, the power plant also includes a series of systems that ensure the normal operation of the engine.

*In addition to these five main parts, the aircraft is also equipped with various instruments, communication devices, navigation devices, safety devices and other devices according to the needs of aircraft operation and mission execution.
