What is the version of win10s

S is like a simplified version of Win10, among which S stands for Streamline (simplification) and also represents School (school) Windows10 S is mainly launched in the education market. The main feature of the system is that it only allows the installation of applications from the Windows 10 app store and will also Prevent the installation of ordinary desktop programs.

Before the official release of Windows 10 S, to be precise, this version of the system should be called Windows Cloud, and only a small range of tests is done. According to Microsoft's official explanation, Windows 10 S is a new Windows experience streamlined for security and excellent performance, targeting teachers and students.

Win10 S belongs to a specialThe Windows 10 version, simply put, is a "simplified version". It has the characteristics of fast startup, cheap price, better compatibility, lower hardware requirements, etc. It is mainly developed for the education market and student users.

Win10 S is a special configuration version of Win10 Professional Edition, which aims to create simplicity, speed, safety and performance. The Win10 S system itself also contains many functions, including Win10 Professional Edition, but it can only run programs in the Win10 app store, including Win32 to UWP applications.

WIN 10 S version is a simplified version of WIN 10, which can only be downloaded from the App Store. Applications other than the app store can't be opened. When upgrading to the professional version, did you select "My organization owns this computer"?

What wiring method (power distribution system)? What are T, N and S?

1. x0dx0aTN-S system x0dx0a TN-S grounding system is a grounding type that strictly separates the working zero line (N line) and the special protection zero line (PE line).As shown in Figure 2.

2. TN-mode power supply system, a protection system that connects the metal shell of electrical equipment to the working zero line, is called the zero protection system, which is represented by TN. The working zero line of the TN-C power supply system is also used as a zero protection line, which can be called a protection neutral line and can be represented by PEN.

3. TN-S system three-phase five-wire system, the transformer output three-phase five-wire system PE is grounded within the specified distance, and the entry end is close to the ground. Five-wire arrival electrical equipment. The device can be directly wired to the user and take the seat! The wires are divided into yellow, green, red, N light blue and PE yellow-green wires.

What are TN-C system, TN-S system and TN-C-S system respectively?

TN-C-S power supply system is in the temporary power supply of construction. If the first part is TN-C power supply, and the construction specification stipulates that the construction site must adopt the TN-S power supply system, then the PE line can be separated from the main distribution box of the site behind the system. The characteristics of the TN-C-S system are as follows.

TN-C-S: The transformer leads to the TN-C method, which begins to distinguish PE and N from PEN at a certain level of power distribution system (the two are not allowed to meet and shake hands after that), that is, it is TN-C type before the divergence point, and then it is similar to TN-S (not real TN-S).

TN-C-S is the first half of the power supply system is the TN-C system, and the second half (power distribution box) is the TN-S system.

TN-C mode power supply system uses a working zero line as a zero protection line, which can be called a protection neutral line and can be represented by PEN. The TN-S power supply system is a power supply system that strictly separates the working zero line N and the special protection line PE, which is called the TN-S power supply system.

TN-C-S is a widely used power distribution system. In industrial and mining enterprises, potential-sensitive electrical equipment is often set at the end of the line, and most of the front end of the line is fixed equipment. Therefore, it is very disadvantageous to change it to the TN-S system at the end of the line.

In the TN system, it is divided into three systems: TN-C, TN-S and TN-C-S: the IEC standard divides the TN system into three types according to the different combinations of N line and PE line: 1) TN-C system-The N line and the PE line are integrated in the whole system (C is the first letter of the word "one" in French Combine).

What does the tn-s system refer to

TN-S system Three-phase five-wire system, the transformer output three-phase five-wire system PE is grounded within the specified distance, and the entry end is close to the grounded. Five-wire arrival electrical equipment. The device can be directly wired to the user and take the seat! The wires are divided into yellow, green, red, N light blue and PE yellow-green wires.

TN-S power supply system is a power supply system that strictly separates the working zero line N and the special protection line PE, which is called the TN-S power supply system. The characteristics of the TN-S power supply system are as follows. 1 )When the system is running normally, there is no current on the dedicated protection line, but there is an unbalanced current on the working zero line.

The TN-C-S system is a system in which the first section of the protection zero line of the trunk part is shared with the neutral line, and the second section of the protection zero line is separated from the neutral line; the TN-C system is a system in which the trunk part protects the zero line and the neutral line is completely shared.

What does car pess system mean

Car pess system can be understood as an anti-theft system, which may not be able to start the car after it appears. The car anti-theft system refers to the system set up to prevent the theft of the car itself or the items in the car. It consists of an electronically controlled remote control or key, an electronic control circuit, an alarm device and an actuator.

Refers to the ratio of the current market price of the stock to the company's earnings per share.Its economic meaning is: according to the current business situation of the company, how many years does it take for investors to make a profit through the company to recover their investment? Static P/E (E is the realized earnings per share) - calculated according to the company's earnings per share in the previous year.

This is speed mode, S super mode, P is power mode, E is economy mode, spe or turtle is safety mode. Battery forklifts, no exhaust gas pollution, with the improvement of environmental protection requirements, the demand has grown rapidly, especially for medium and small tonnage battery forklifts.

that is, the PES formula, P (problem, nursing diagnosis name) E (etiology, related factors) S (symptomsandsign, symptoms and signs, including other examination results), is mostly used in existing nursing diagnosis.For example: inefficient breathing pattern (P): cyanoea, shortness of breath (S): related to chest pain (E).

pes is an ethylene-vinyl acetate copolymer. PES is a transparent amber atypical resin with excellent heat resistance, excellent dimensional stability, and good chemical resistance. In addition, PES shows excellent reliability against sudden temperature changes, and has excellent reliability in long-term use at high temperatures.

Formula Nursing diagnosis includes three parts, called PES formula. ( 1) Health problem (Problem) is the name of nursing diagnosis, which is a description of the existing or potential conditions of individual health. These questions all reflect the changes in health status, but do not indicate the extent of the change.

What does the tn-s system refer to?

1. The TN-C-S system is a system in which the first section of the trunk part protects the zero line and the neutral line, and the latter section protects the zero line and the neutral line; the TN-C system is a system in which the trunk part protects the zero line and the neutral line.

2. TN-S system refers to a low-voltage power distribution system, which is controlled by a power distribution substation (usually reducing the transmission voltage of the power grid to a distribution voltage), a high-voltage distribution line (i.e. a voltage of more than 1 kV), a power distribution transformer, a low-voltage distribution line (voltage below 1 kV) and corresponding control protection. Equipment composition.

3. TN-S power supply system is a power supply system that strictly separates the working zero line N and the special protection line PE, which is called the TN-S power supply system. The characteristics of the TN-S power supply system are as follows.1) When the system is running normally, there is no current on the special protection line, but there is an unbalanced current on the working zero line.
