Some of you will actually design and build operating systems or components of them. Perhaps more now than ever Many of you will create systems that utilize the core concepts in operating systems. Whether you build software or hardware The concepts and design patterns appear at many levels All of you will build applications, etc. that utilize operating systems The better you understand their design and implementation, the better use you’ll make of them. Operating systems (OS) can help computer users do many things, like managing and manipulating files and folders.. Operating systems also provide users the ability to control hardware components of a computer and its peripheral devices, like printers and scanners.. ‹#›. ICS 143A - Principles of .
