Document Summary

Application software programs that help us solve real-world problems; written to address specific needs. System software programs that manage computer system and interact with hardware at fundamental level; provides tools and environment in which application software can be created and run. Utility software programs performing various activities fundamental to computer installations but not part of os. Operating system system software that manages computer resources and provides interface for system interaction. Shell provides interfaces though which human can interact with computer. Kernel manages computer resources, such as memory and input/output devices. Allows application programs to interact with other system resources. Manages resources and these resources often shared among programs that want to use them. Multiprogramming technique of keeping multiple programs in main memory at same time, competing for cpu. Memory management act of keeping track of how and where programs are loaded in main memory. Process dynamic representation of program during execution.
