Operating system Every computer has an operating system. NEXT
Operating system Operating systems provide a basis for application programs and acts as an intermediary between user and hardware. An operating system is sometimes called the software environment or platform. BACK NEXT
Operating system Operating systems handles behind the scene activities that we don’t usually consider. These tasks include: 1. Loading and running programs 2. Organizing files 3. Coordinating networks that share resources BACK NEXT
Categories of Operating systems - Environments Three main environments of operating systems 1. Stand-alone operating system – Desktop 2. Networked operating system – Linked computers 3. Embedded operating system – Hand-held BACK NEXT
Categories of Operating systems - Divisions Two distinct divisions of operating systems 1. Proprietary - Owned and licensed by a corporation - Most operating system are proprietary 2. Non-Proprietary - Source code is free and available to the public - Called an open source program BACK NEXT
