Document Summary

Portability allows programs to work on multiple os; rare and difficult; e. g. , word on apple and windows. Extensions type of data to open files quicker; e. g. , . exe. Single task os 1 program at a time, usually on cellular devise. Multi-task os more complicated, multiple programs, cpu does the instruction within seconds and continues to the next, more open programs = more memory use = decrease in speed; more complex. The ability of an operating system to run more than one application at the same time is known as multitask. Multi-user os common for computers; use of login and password; controls what will be seen or not. Peripheral or device drivers used to allow os to communicate with devices like printers; e. g. , plug and play programs. The portion of an operating system that interfaces with hardware drivers, such as printers are called device/peripheral drivers. Virtual memory for not having enough ram; appear to have more memory; puts data into the hardrive.
