History of Operating Systems Early computers lacked any form of operating system. The user had sole use of the machine; he would arrive at the machine armed with his program and data‚ often on punched paper tape. The program would be loaded into the machine‚ and the machine set to work‚ until the program stopped‚ or maybe more likely‚ crashed. Programs could generally be debugged via a front panel using switches and lights; it is said that Alan Turing was a master of this on the early Manchester

Internet Operating Systems Andrew S Minette POS/355 University of Phoenix Internet operating systems‚ or Web operating systems‚ are not operating systems per say. There are more of user interfaces. An operating system is dependent on system hardware and uses hard disk space on a user computer to install and store applications. Web operating systems‚ however‚ depend on traditional operating systems to run an instance. According to Jonathan Strickland or How Stuff Works‚ while there may not

2.1 TYPES OF OPERATING SYSTEM A. Batch Operating System- Batch processing is the most primitive type of operating system. Batch processing generally requires the program‚ data‚ & appropriate system commands to be submitted together in the form of a job. Batch operating systems usually allow little or no interaction between users & executing programs. Examples of such programs include payroll‚ forecasting‚ statistical analysis‚ & large scientific number-crunching programs. Serial processing combined
