What is the computing level of the computer?
How many levels of computers are there? The national computer grade examination is divided into four grades, as follows:
A DOS version and a WINDOWS version;
There are five language categories in the second level: BASIC, FORTRAN, PASCAL, C language and FOXBASE；;

How many grades of steel bars are there? Hot rolled steel bars in China can be divided into four grades according to their strength:
1.Ⅰ grade reinforcement
Its strength grade is 24/38kg, and it is a round steel bar rolled from killed steel, semi-killed steel or boiling steel No.3 ordinary carbon steel. It is a low-strength steel bar, which has the characteristics of good plasticity, high elongation (Δ 5 is above 25%), easy bending and forming, and easy welding. It has a wide range of uses, and can be used as the main stress reinforcement of small and medium-sized reinforced concrete structures, stirrups of components, tie rods of steel and wood structures, etc. Wire rod reinforcement can also be used as raw material for cold-drawn low carbon steel wire and double reinforcement.
2. Grade Ⅱ reinforcement
Grade II steel bars are rolled with low-alloy killed steel or semi-killed steel, and silicon and manganese are used as solid solution strengthening elements. Grade Ⅱ rebar has a strength grade of 34(32)/52(50) kg, high strength, good plasticity and ideal weldability. Long longitudinal bars and evenly distributed transverse bars are rolled on the surface of steel bars, which can strengthen the bond between steel bars and concrete. Using grade II steel bar as the stressed steel bar of reinforced concrete structure can save 40 ~ 50% of steel compared with grade I steel bar. Therefore, it is widely used in large and medium-sized reinforced concrete structures, such as the main reinforcement of bridges, dams, port engineering and building structures. Secondary steel bars can also be used as prestressed steel bars in building structures after cold drawing.
3. Grade Ⅲ steel bar
The main performance of tertiary reinforcement is roughly the same as that of secondary reinforcement, and the strength grade is 38/58kg.
4. Grade Ⅳ reinforcement
Grade Ⅳ steel bar has a strength grade of 55/85 kg, and is rolled from medium carbon low alloy killed steel. In addition to silicon and manganese, vanadium or titanium is added as solid solution and precipitation strengthening elements to improve its strength and ensure its plasticity and toughness. The surface of grade Ⅳ steel bar is also rolled with longitudinal and transverse ribs, which is the main prestressed steel bar in building construction. Grade Ⅳ steel bars should be cold-drawn by the construction unit before use, and the cold-drawn stress is 750 MPa, so as to improve the yield point, give play to the inherent potential of steel and achieve the purpose of saving steel. The yield point of cold-drawn steel bar is not obvious, so it is designed according to the statistical value of cold-drawn stress (cold-drawn design strength). However, after several months of natural aging or artificial heating aging, the steel bar will have a short yield step, which is slightly higher than the cold-drawn stress, and the steel bar will have a hardening trend, which is called "age hardening". Therefore, while ensuring the specified cold-drawn stress, the cold-drawn elongation should be controlled not to be too large to prevent the steel bars from becoming brittle. Grade Ⅳ steel bars have high carbon content, so the process of flash-preheating-flash welding or electric heating after butt welding is generally adopted to ensure that the welded joints, including the heat affected zone, do not produce hardening ability and prevent brittle fracture. The diameter of grade Ⅳ steel bar is generally 12mm, which is widely used in prestressed concrete slab members and for binding large prestressed building members (such as roof trusses and crane beams). When hot-rolled grade Ⅳ steel bar is used as prestressed steel bar, it still needs cold drawing and welding, and its strength is still low, which needs to be further improved.

After you have selected a set of titles, you can also go to the "modify titles" in the personal center to modify them and change them into another set of titles. After this operation, your rank will remain unchanged, and your title will only change horizontally. For example, when you get to the third level, your title is company white-collar series, that is, assistant, and then you go to the personal center to change your title to imperial examination winning series, and then after you log in again, your title will be displayed as "scholar"
Post bar users can log in directly when they know it. By default, your title is "company white collar", and then you can go to the personal center to re-select a set of titles you like.

What are the grades of rain? When we listen to or watch the weather forecast, we often hear terms such as "light rain", "moderate rain" and "moderate to heavy rain", which is the grade of rainfall. Rainfall means that the rainwater falling on the ground is not evaporated, infiltrated and lost, but is determined by the depth of accumulation. The unit of depth stipulated in our country is millimeter. The level of rainfall is divided into light rain, moderate rain, heavy rain, heavy rain, heavy rain and torrential rain according to the rainfall within 24 hours. Light rain: the rainfall is less than10mm, and the raindrops are clear, which is debatable. When they fall on the roof tiles and hard ground, they will not splash, and the rain will be gentle and intermittent; It usually takes two minutes to completely wet the slate and roof tiles, and the puddle is slowly formed. Moderate rain: the rainfall is between ten and twenty-five millimeters, and the rustling rain can be heard. Rain falls like a line, and raindrops are not easy to distinguish. They splashed gently on the holes and hard ground, and puddles soon formed. Heavy rain: the rainfall is between 25 and 50 mm. When it rains heavily, the rain falls like a downpour, dripping on the roof tiles and hard ground, splashing several inches. The rain is like a drum, and the pool is quickly formed. Heavy rain: the rainfall is between 50- 100 mm, and there is water on the road surface. Rainfall between 100 mm and 200 mm is called rainstorm; Rainfall exceeding 200 mm is called rainstorm, and low-lying areas are flooded. Shower: refers to stratum precipitation, with heavy raindrops and drastic changes in intensity. When it rains, it is dark, sometimes it suddenly clears up, revealing sunny days, and sometimes it is accompanied by thunder.
What is the accuracy of the water meter? The accurate grade of water meter is divided into: A B C D.
The level of D is the highest, and the level of B is basically used in China.
Before 1996, the water meter standard was marked on the water meter core.
The new water meter standard GB/T778-2007 is that the meter core is not marked with many grades, but there are flow parameters indicating the water meter grades.
How's the computer performance? WINDOWS B is a paperless exam.
The second level examines the examinee's basic knowledge of software and hardware and the ability to program and debug on the computer with a high-level computer programming language. Including VISUAL BASIC programming, VISUAL FOXPRO programming, QBASIC programming, FORTRAN programming, C programming, FOXBASE programming.
The third level is divided into four categories, namely PC technology, information management technology, network technology and database technology.
Level 4 examines the necessary ability of analysis and design of computer application projects or application systems.
Candidates apply for one grade at a time. If there are different grades, choose one of them. The examination includes two parts: written examination and computer operation. Those who pass the examination shall be issued a certificate by the examination center of the Ministry of Education, which is common throughout the country.
What are the secret levels of official documents? "Top secret", "secret" and "secret" are three levels.
