•Hardware and software combine to solve specific problems
–Software: Application logic providing a service or solves some problem: entertainment, information management, scientific problem solving, system control, forwarding packets in a router, etc.
Although strictly speaking many solutions can be designed and implemented entirely in hardware but this is a course on operating systems.

–Hardware: provides the basic computing resources (Processor(s), Memory, System Bus and I/O modules).
•Software is divided into two categories:
–System software: simplifies application programming by creating convenient to use programming and run-time environments.
•Resource Management: time and space multiplexing of system resources
•Extended virtual machine: standardized interfaces and abstractions simplify programming and system use
–Application software: used directly by user (person, another program or computer system) to solve some problem.
