Computer Programming Pdf Pdf Object Oriented Programming Class Computer Programming History of operating systems 1.1 why study operating systems? abstraction: os is a wizard, providing illusion of infinite cpus, infinite memory, single worldwide computing, etc. system design: tradeoffs between performance and simplicity, putting functionality in hardware vs. software, etc. how computers work: "look under the hood" of computer. Software systems, buzzwords, issues • operating systems – runs programs, controls the computer, stores information, communicates • applications ("apps") – programs that do things • cloud computing, virtual machines, – where boundaries become even less clear • intellectual property – copyrights, patents, licenses.
