What is an operating system?
what is an operating system? a collection of programs thatmanage computer resources (CPU, main memory, secondary memory, I/O devices)provide a working environment for the userwith the following goals:manage computer resources efficientlymake a computer system convenient to useAn OS manages a variety of system resources:CPU (time)main memory spacefile storage spaceI/O devicesAn OS allocates and deallocates resources to executing programs (or processes) and may resolve conflicts.
Operating system historyhistorically, programmer was the OSload program (switches, paper tape, cards)set starting addressmonitor executionassemblers, linkers, and loaders eventually helpedcompilers and high-level languages helped the programmer by providing a higher level of abstractionprofessional operators handled job setup and executionprogrammer debugged problems from memory dumpsoperators grouped multiple programs with similar characteristicsbatch system allowed no interaction between the user and the executing programthe biggest problem was (and still is) the discrepancy between the speed of the CPU and the speed of I/O devices; two solutions:off-line processingdisk spooling, which often results in a group (pool) of jobs ready to run when the running job finishes.
