A file is a record or a set of data. More precisely, a file is a sequence of bytes organized What is Process Spawning? What is Time Slicing? What is Device Driver? Concurrent Engineering : Simultaneous performance of the various stages of product development Manufacturability and Value Engineering : Activities that help improve a product's design, production, Robust Design : Design that can be produced to requirements even In this technique, time of single processor is shared in among of multiple users over the entire network system simultaneously.

Time-sharing operating system implements CPU scheduling and multi programming system which to deliver to every users a small piece of operating time. The technique of time sharing system relates with batch processing systems. In an operating system software performs each of the function:. The kernel is the central component of a computer operating systems. The only job performed by the kernel is to the manage the communication between the software and the hardware.

A Kernel is at the nucleus of a computer. It makes the communication between the hardware and software possible. While the Kernel is the innermost part of an operating system, a shell is the outermost one. A monolithic kernel is a single code or block of the program.

It provides all the required services offered by the operating system. It is a simplistic design which creates a distinct communication layer between the hardware and software. Microkernel manages all system resources. In this type of kernel, services are implemented in different address space.

The user services are stored in user address space, and kernel services are stored under kernel address space.
