AN OPERATING SYSTEM IS PROGRAM THAT ACTS
AS AN INTERFACE BETWEEN THE USER AND THE HARDWARE OF THE
COMPUTER. IT ALSO MANAGES THE COMPONENTS OF THE MACHINE SUCH AS
PROCESSOR MANAGEMENT, DISK RESOURCE MANAGEMENT, INPUT OUTPUT FILES, DEVICES
ETC.
THE OPERATING SYSTEM CAN BE CLASSIFIED ON
VARIOUS PARAMETERS.
IN THIS SECTION WE WILL LEARN THE CLASSIFICATION OF THE OPERATING SYSTEM BASED ON THE NUMBER OF USER AND THE NUMBER OF TASK PERFORMED BY OPERATING SYSTEM THAT RUN SIMULTANEOUSLY ON THE COMPUTER.
SO LETS BEGIN
CLASSIFICATION BASED ON THE NUMBER OF USER
BASED ON THE NUMBER OF PEOPLE ACCESSING THE COMPUTER, THE OPERATING SYSTEM CAN BE CLASSIFIED NAMELY IN TWO TYPES NAMELY SINGLE USER OR MULTI USER. AS SHOWN IN LIST BELOW
SINGLE USER :- IN THIS TYPE OF OPERATING SYSTEM ONLY ONE USERS CAN ACCESS THE RESOURCES OF THE OPERATING SYSTEM AT A TIME. EXAMPLE OF SINGLE USER INCLUDE DOS AND MICROSOFT WINDOWS
MULTI USER :- IN THIS TYPE OF OPERATING SYSTEM MORE THAN ONE USER CAN SIMULTANEOUSLY ACCESS THE COMPUTER RESOURCES. EXAMPLE OF MULTIUSER OPERATING SYSTEM INCLUDE UNIX, VMS (VIRTUAL MEMORY SYSTEM) AND MAINFRAM OPERATING SYSTEM (MULTIPLE VIRTUAL STORAGE) MVS , LINUX, UNIX, NOVEL NETWARE ETC.
CLASSIFICATION BASED ON THE NUMBER OF TASK
BASED ON THE NUMBER OF TASK THAT CAN RUN SIMULTANEOUSLY ON A COMPUTER THE OPERATING SYSTEM CAN BE CLASSIFIED NAMELY SINGLE TASKING OR MULTI TASKING. THEY ARE EXPLAINED BELOW.
SINGLE TASKING :- A SINGLE TASKING OPERATING SYSTEM ALLOWS THE USER TO PERFORM A SINGLE TASK AT A TIME. EXAMPLES OF OPERATING SYSTEM ARE DOS, PALM OS FOR HANDHELD PALM COMPUTERS.
MULTITASKING :- A MULTIPLE TASKING OPERATING SYSTEM ALLOW
THE USER TO SIMULTANEOUSLY WORK ON DIFFERENT PROJECTS OR ON DIFFERENT PROGRAMS.
EXAMPLE OF MULTI OPERATING SYSTEM INCLUDE MICROSOFT WINDOWS AND APPLE MAC
OS. AN EXAMPLE OF MULTITASKING CAN BE
COPYING FROM ONE FILE TO ANOTHER FILE OR FROM ONE DRIVE TO ANOTHER AND
