Explain why do computer manufacturers typically made their new processors backward compatible with their earlier processors?

Being compatible relates with earlier versions of a certain model being same with the older version. An advanced version of a program is regarded to be backward compatible if it can use files and information or data created from a previous model of a similar program. A PC is known to be backward compatible when it exhibits traits of running a similar software as the previous model of the computer. The backward compatibility of a computer is essential since it diminishes the requirement to start over when the need to upgrade the computer to a modern version arises.  An example, A regressive word processor, permits an individual to edit or alter some documents made with a past rendition of the model. As a rule, makers attempt to keep every one of their items in reverse good. Here and there, notwithstanding, it is important to relinquish in reverse similarity to exploit another innovation. The compatibility of the processors allows the makers and innovators to save on time that is required to come up with new programs or models. The time saved translates to a sum of money that is saved during the process of making system compatible. Saving on time gives innovators time to come up with more advanced systems. Also, the older version maintains its strengths when the new processors are advanced resulting in a more efficient and productive program. The compatibility allows programmers to identify challenges of a previous model and have the capacity to alter it allowing it to perform better.
