ESP systemThe electronic stability Program was an electronic stability system for cars. It was a brand-new generation of active safety control system that could significantly improve the vehicle's handling stability under various extreme conditions.
Its function was to monitor the driving state of the vehicle. By monitoring the parameters such as the steering direction, wheel speed, sideslip, and lateral acceleration of the vehicle, it could perform dynamic stability control on the vehicle to ensure that the vehicle remained stable in an emergency and prevent the vehicle from deviated from the ideal trajectory. The ESP system can automatically apply braking force to one or more wheels to ensure that the vehicle is running on the normal lane and can also automatically correct the vehicle's trajectory.
The EP system was not an independent system, but was built on the basis of the Anti-lock Braking System (ABS) and the Acceleration Slip Control System (ASR). It was composed of sensors (such as steering sensor, wheel sensor, sideslip sensor, and lateral acceleration sensor), an ESP computer executor, and an ESP lamp on the dashboard. The principle was to control the stability of the vehicle through direct yawing moment, which meant that the braking force and driving force of the four tires were independently controlled to generate additional yawing moment, so that the vehicle could track the ideal control target according to the driver's driving intention under various working conditions. ESPs could be divided into four or four channel systems, two channel systems, and three channel systems. They had the characteristics of active safety, real-time response, multi-functionality, individual adaptation, and improved control performance.
When the car is driving, when there is understeer, oversteer, or slipping on the road, the ESP system can effectively prevent the car from losing control and greatly improve the safety of the car. However, in some special situations, such as off-road driving, driving through sand and snow, sinking into quagmire, or drifting and other extreme driving, the ESP system would limit the engine speed. At this time, it was necessary to turn it off to increase the speed of the engine wheels.
Most cars would have an EP system, some cars would have it as standard equipment, and some would have it as an option. It was difficult to install the EP system. It was not recommended to install it later because it was composed of a series of sensors and needed to go through a series of tests and debugs. Even if the later installation was successful, it could not guarantee that it would work at a critical time and might even bring potential risks.

Ipsec-esp protocolAn architecture that was designed to provide security services in a hybrid application of both the IPv4 and IPv6 networks.
It provides confidentiality and integrity by encryption of the data to be protected and placing the encrypted data in its data portion. It uses a symmetrical key encryption algorithm to provide data integrity verification, data source verification, and anti-replay attack services.
Depending on the user's security requirements, it can be used to encrypted the transmission layer (such as IP, IP, IGMP), or it can be used to encrypted the entire IP packet. Encapsulated protected data was necessary to provide confidentiality for the entire raw data report.
The EP header can be placed after the IP header, before the upper layer protocol header (in the transport layer mode), or before the encapsulated IP header (in the tunnel mode). The protocol value assigned by Ivana to the EP header is 50. The protocol header before the EP header will contain the value 50 in the "next head" field of the IP version 6 or the "protocol" field of the IP version 4. The ESP contains a non-encrypted protocol header followed by encrypted data. The encrypted data covers the protected ESP header field and protected user data. The user data can be the entire IP datagrams or the upper layer protocol frame of the IP (for example, the protocol of a protocol such as a protocol or a protocol such as a protocol.
In addition, the set of services provided by the EP is determined by the options selected and the arrangement of the implementation when the secure connection (Sa) is established. The confidentiality option is independent of other services, but using the confidentiality service without the integrity/authentication service (in the EP or in AH alone) may cause the transmission to be subject to some form of attack and destroy the confidentiality service. Data source verification and integrity of the non-connection are related services, provided to the user in combination with confidentiality (option). The anti-replay service can only be selected when the data source verification is selected, and the receiver can decide the choice of the anti-replay service alone.

What does ESP mean?There are many meanings to ESP. The following are the common ones:
1. It was the short form of the Executive and Organizing Program.
2. In the field of cars, the electronic stability program was used to prevent the car from losing control when the car understeered, oversteered, or skidded on the road. It was an important configuration to improve the safety of the car.
3. EP can also refer to the EFL system partition, which is a physical partition in the FAT16 or FAT32 format. The partition label is EP (hex), which is generally not visible under the Windows operating system. A computer that supports the EFL mode needs to boot the system from the ESP. The EFL firmwares can load the EFL boot program and applications from the ESP. It can also be used to store system-level maintenance tools and data.
4. In a specific context, esp could also refer to super-intuitive ability, from the book "Stupid Chick's Magic ESP."

What is programming? What does programming mean?It was the process of letting a computer solve a certain problem on behalf of a certain calculation system, and making the calculation system operate according to the calculation method, and finally obtain the corresponding result. In order for the computer to understand human intentions, humans needed to tell the computer the ideas, methods, and means to solve the problem in a form that the computer could understand. The process of communication between humans and the computing system was programming. The programming here was not necessarily for computer programs. Any system with logical computing power could be considered programming.
The programming class was a course that taught knowledge and skills related to programming. In the programming class, students would learn the basic grammar of programming languages (such as data types, operators, branches, and cycles, etc.), use the programming language to implement basic data structures (such as sequence tables, linked lists, etc.), improve their programming thinking and problem solving skills by brushing algorithm questions, and carry out practical projects. For children's programming, they would use more interesting and child-friendly methods, such as using beautiful game screens, cute animated characters, and a standardized programming interface. They would let children learn to break down complex problems into simple steps and write code to execute these steps, thereby cultivating logical thinking, computational thinking, and creative thinking.

In general, programming robots were an interesting and practical tool that could help people learn and apply programming techniques.
NC programmingNumerical-control programming was one of the main contents of the preparation stage of Numerical-control processing. The process was the whole process from the part drawings to obtaining the Numerical-control processing program. This included analyzing the part drawings, determining the processing process, calculating the tool path to obtain the tool location data, writing the numerical control processing program, making the control medium, checking the program, and the first piece of trial cutting.
There were two methods of programming for the numerical control processing, manual programming and automatic programming. The various stages of manual programming were completed manually. The programmer used general calculation tools to calculate the tool trajectory and compile instructions manually through trigonometric-function calculation. This method was relatively simple, easy to master, and had great adaptability. It was suitable for non-mold processing parts. The steps included manually completing the numerical control process of the parts, analyzing the parts drawings, making process decisions, and determining the processing route.
In programming, there was also the special function of the user macro program. There were some differences between the user macro program and the normal program. In the user macro program, variables could be used and assigned values. The variables could be calculated, and the program could jump. However, the normal program could only specify a constant, and the constant could not be calculated. The program could only be executed in sequence and could not jump. The function was fixed. The format of the macro program itself was the same as that of the subprogram. It could use normal, variable, calculation, and control commands. For example, in some engineering application scenarios, such as the calculation of circular arc evenly distributed holes, oval processing, etc., the use of macro programs could improve the efficiency of manual programming.

What is programming?" Program " was the short form of programming. The essence of programming was to let a computer solve a problem on its behalf. This process required a specific calculation method for the calculation system to operate in this way to obtain results. In order to achieve this goal, humans had to transform the ideas, methods, and means of solving problems into a form that the computer could understand, so that the computer could work step by step according to the instructions to complete specific tasks. The process of communication between humans and machines was programming. In addition, programming could also be seen as designing a " controllable system " with logical flow. Moreover, programming was not necessarily limited to computer programs. The operations related to systems with logical computing capabilities could also be considered programming.
