Application program (foreign abbreviation: App, foreign full name: application).
Due to the popularity of smartphones such as Android.iPhone, it refers to the third-party applications of smartphones. Well-known app stores include Apple's AppStore, Google's GooglePlayStore, Nokia's Ovistore, BlackBerryAppWorld and Microsoft's Marketplace.
2:APP is the abbreviation of AeleratedParallelProcessing. Accelerated parallel processing technology. It is a general parallel computing technology introduced by AMD for its GPU. Using this technology, we can give full play to the parallel computing ability of AMDGPU, which can be used to speed up the operation of software or carry out large-scale scientific operations.
3. In VC, app is the entrance and exit of the application, where you usually handle some setting information that needs to be read or written when starting and exiting the program, and set some global variables.
4. Application middleware
Appserver, formerly known as middleware, has a much longer history. As early as 1960s and 1970s, it has been widely used in IBM mainframe system, and it is called TPMonitor. The famous ones are Tuxedo of BEA and CICS of IBM, which run on the server side of terminal/server mode. Its main function is to separate business logic, conduct distributed computing, and automatically manage transactions, resources and fault tolerance. Because of the long development time, the technology is very mature. Middleware was first written in cobol, and now we can occasionally see the old system of cobol's middleware. Later, middleware was implemented in C. The famous middleware is CICS of IBM and Tuexdo of BEA, which are still widely used in high-end systems, especially banking systems.
5: The suffix of snow carp application is app. Snow carp platform is a mobile phone application platform developed by Shanghai Snow carp Computer Technology Co., Ltd. (this platform is used by a large number of domestic/cottage machines), which is also the STEP platform.
This platform is an application development engine based on MTK, ADI and Spreadtrum. These mainstream built-in platforms were originally closed platforms. By installing the STEP platform, external applications can be loaded through external storage, so that the user's mobile phone platform has the extended functions of smart phones. The platform comes with a reasonable billing scheme, so that all partners can get reasonable income through the software store.
6:
Random polypropylene (APP) is a by-product of polypropylene (isotactic polypropylene) and a sticky substance.
constitutional formula
The average molecular weight is 3000- 10000. Sometimes it can reach tens of thousands.
It is an amorphous, slightly sticky white waxy solid at room temperature and begins to decompose at 200℃. Soluble in organic solvents such as alkanes, aromatics and esters, insoluble in ethanol, acetone and water. Because of its small molecular weight, irregular structure and low cohesion, its mechanical properties and heat resistance are poor.
7:
The English abbreviation of high-efficiency wood flame retardant is app- ammonium polyphosphate, and the molecular general formula is (NH3)n2PnO3n 1. White powder, density1.74; Break the chain in strong acid solution to produce ammonium phosphate. Close to neutrality, good dispersibility, and no reaction with other substances. Good thermal stability, decomposition temperature is not lower than 250℃. Low toxicity.
Used as additive flame retardant. When it is decomposed by heat, it produces ammonia and very stable polyphosphoric acid, which can be a protective layer of polymer and isolate oxygen. It can also be used in combination with other flame retardants.
