What do you mean by upward compatibility?

Question 1: What is the difference between backward compatibility and upward compatibility? Backward compatibility means that the high version supports the low version, or the later developed version supports and is compatible with the earlier developed version, with little upward compatibility. Most software is backward compatible. For example, office20 10 can open word files built by office2007, office2006, office2005 and office2003, but office2003 cannot open word files built by office2007 and office20 10!

Question 2: Are the following statements about the concepts of upward compatibility and backward compatibility correct? Please provide strong supporting arguments. Up and down are the same as forward and backward. Up and down are relative. For software, backward compatibility means that the higher version of the program can handle the lower version of the data smoothly. The same is true for hardware. New products support old products. (backward compatibility), of course, old products support new products. For old products. It is upward compatible. Compatibility depends on the new product.

Question 3: What do you mean by compatible version? Compatibility is different from backward compatibility.

The new version can support the backward compatibility of the old version.

Sometimes the new version can be backward compatible, but many times it is necessary to give up the old code. At this time, the old client needs to find a dll compatible with his old version. That is, a branched version is generated.

Second, upward compatibility means that the old version can be compatible with the new version. If it is compatible from top to bottom, it is completely compatible, and there is no need to make a branch version. If the old version is compatible with the new version, it means that the new version does not increase the interface, but narrows the interface. This is also a factor in generating the version.

Generally, there are many backward compatibility, such as software under win7 or xp system.

Question 4: What is the difference between upward compatibility and backward compatibility? Can you give me a simple example? Upward compatibility means that it can be improved and there is room for renewal. Backward compatibility, can only maintain the status quo, can only use older applications.

Question 5: The software compatibility of serial computers must be backwards compatibility, and strive for upward compatibility as far as possible? What do you mean, backward compatibility means that the software runs on the machine before it is put into use, and upward compatibility means that it runs on a higher-end similar machine.

Question: What are the upward compatibility and backward compatibility of Android? The high-end system is compatible with the software of the low-end system (for example, 4.0 is also compatible with the software of penalty.3).

Upward compatibility: Contrary to backward compatibility in theory, this situation hardly exists in practice.

Hope to adopt.

Question 7: What does Mitsubishi PLC mean by backward compatibility? It is best to explain all backward compatibility and upward compatibility of PLC, thank you! In other words, the higher version of PLC is compatible with the lower version of PLC. In other words, the higher version of their functions retains the lower version of their functions.

There is no saying that chickens are upward compatible.

Question: How can word2007 be upward compatible with 20 10? This doesn't need mending. The document formats are all do X, xslx, etc. 2007 is consistent with 20 10. Only in 2003 did you need to install your own patch bag.

Question 9: Can memory be upward compatible? Backward compatibility means that the memory of DDR400 can work in DDR333 266 133 mode.

Memory is not upward compatible. If your motherboard only supports Hai 00 memory, then you can't plug in II 533 667 800, and you can only use less than 400 memory.

Question10: Can Android software be backwards compatibility or upward compatible? Theoretically, the new high version can be compatible with the old low version, but the reality is that the compatibility is not good.
