how does the operating system interact with application software ?


With the software applications feed the CPU the intructions it needs to process data. these intructions take the form of computer code. Every software application, no matter what its type or manufacturer, needs to interact with the CPU. For programs to work with the CPU, they must contain code that the CPU recognize. rather than having the same blocks of code for similar pro-cedures in each software application, the operating systerm includes the blocks of code that applications need to interact with it.

what is a blog?
----> weblogs (or blogs) are personal logs, or journal entries, that are posted on the web. The beauty of blogs is that they are simple to create, manage, and read. Although different types of blogs exist, there are some basic similarities. first, blogs are arranged as a listing of entries on a single page, with the most recent blog (entry) appearing on the top of the list. second, blogs are public. everyone who has a web browser and access to the internet can read a blog. Finally, blogs are searchable, making them user friendly.
