In a simple timeshare operating system all processes receive a time "slice", meaning that a process can run for a specified amount of time, typically measured in fractions of a second.
In a simple realtime operating system, all processes are assigned a process "priority" If a process is ready to run and it has a higher priority than other processes, the process has control of the CPU until the process gets to a point that it is no longer "ready". That can mean that the process is waiting for I/O or for the completion of some event. If multiple process with higher and equal priority are "ready", the CPU is typically shared between them, using some kind of timesharing.
Most of todays operating systems use a blending of the concepts.
Micro-Kernel: A micro-kernel is a minimal operating system that performs only the essential functions of an operating system. All other operating system functions are performed by system processes. Monolithic: A monolithic operating system is one where all operating system code is in a single executable image and all operating system code runs in system mode
what is difference between mild steel and stainless steel
The Operating System (OS) connects the user, applications, and hardware together.
Application can be made by developers not working for Operating System. System Software cannot be created by other people.
An operating system is software that resides between user applications and hardware. It's job is to manage hardware resources and allocate them to the user applications through processes such as memory management and process scheduling.
difference between operating system and system software?
they difference is the network operating system is the type of system that a computer or -IT technology Company uses after it has trademarked it. The OPERATING SYSTEM is the home version
Linux is an operating system kernel. It is a portion of the software that makes up a complete operating system.
Differentiate between Simple Batch Operating Systems and Time-sharing Operating Systems
unix is a multiuser operating system but widows is a single user operating system.

No difference, really. Unix is an OS (Operating System)
Windows is a general purpose operating system and Novell NetWare is a network operating system
Eclipse Computers is an online computer hardware retailer. Computers made from these parts can be paired with a Windows operating system in order to resemble a PC, or with another operating system such as Linux.
Unix is a multi user, multi processing and multi tasking operating system
