Operating Systems (OS's)
Operating Systems, or OS's, are software systems that manage computer hardware. Operating systems also provide the platform for which applications can be installed on. Application programs require an operating system to run on. Operating systems control the communication between the software and hardware of an electronic device. For hardware functions such as input, output, and memory allocation, the operating system acts as the intermediary between the programs and the computer hardware. Operating systems can be found on almost any device that contains a computer, like desktop computers, laptops, netbooks, servers, tablets, smartphones, video game consoles, and supercomputers. Here are some examples of some popular operating systems:
The specific versions of these operating systems are not listed. All these operating systems have roots in UNIX, except Windows and z/OS.
