What is a system software ?

A computer's operating system is an example of system software.

System software is software on a computer that is designed to control and work with computer hardware.

The two main types of system software are the operating system and the software installed with the operating system, often called utility software.

The operating system and utility software typically depend on each other to function properly.


A utility or software utility:

A utility or software utility is computer system software knowing to analyze, configure, monitor, or help maintain a computer.

Typically a utility is smaller than a standard program in size and may be included with an operating system or installed separately.

Types of system software:
System software includes:
Operating systems.
Device drivers.
Middleware.
Utility software.
Intel driver page.
BIOS chip details the data of systems firmware.
BIOS setup utility. ...


Some system software is used directly by users and other system software works in the background.

System software can allow users to interact directly with hardware functionality, like the Device Manager and many of the utilities found in the Control Panel.
Ex:In ASP.Net ->caching



In all versions of Windows the drivers are stored in the C:\Windows\System32 folder in the sub-folders Drivers, DriverStore and if your installation has one, DRVSTORE. These folders contain all the hardware drivers for your operating system

  Conclusion : system software 

System software, is the software within the OS designed to provide services to other software, and for hardware functions such as input and output and memory allocation, it acts as an intermediary between programs and the computer hardware.

An operating system (OS) is the software that manages computer hardware and software resources and provides common services for computer programs and enables users to interact with the hardware.

API: Get o.s services

Application software (App) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Application software refers to all applications collectively.
UI: intract users

Multitasking,Multi programming & Multiprocessing

Home Multitasking (Time sharing) Multitasking has the same meaning of multiprogramming but in a more general sense, as it refers to having multiple (programs, processes, tasks, threads) running at the same time.  This term is used in modern operating systems when multiple tasks share a common processing resource (e.g., CPU and Memory). Multitasking:As the name itself suggests, multi tasking refers to execution of multiple tasks (say processes, programs, threads etc.) at a time.  Ex: In the modern operating systems, we are able to play MP3 music, edit documents in Microsoft Word, surf the Google Chrome all simultaneously, this is accomplished by means of multi tasking. Multitasking is a logical extension of multi programming. Multi programming  In a modern computing system, there are usually several concurrent application processes which want to execute.  Now it is the responsibility of the Operating System to manage all the processes effe

(PCB) or Task Control Block (TCB)

Home (PCB)   or   Task   Control   Block   (TCB) •   As   the   operating   system   supports   multi-programmin g ,   it   needs   to keep track of all the processes •   T he   process   control   block   (PCB)   is   used   to   track   the   proces s ’s execution status. •   Each   block   of   memory   contains   information   about   the   process   state,   program   counter,   stack   pointe r ,   status   of   opened   files, scheduling algorithms, etc. •   All   these   information   is   required   and   must   be   saved   when   the  process   is   switched   from one state to anothe r . •   The   process   table   is   an   array   of   PCB’s,   that   means   logically contains a PCB for all of the current processes in the system.

Buffering, Polling & Spooling

Home Buffering Kernels provide many services related to I/O.  Several services—scheduling, buffering, caching, spooling, device reservation, and error handling—are provided by the kernel’s I/O subsystem and build on the hardware and device-driver infrastructure. A buffer, of course, is a memory area that stores data being transferred between two devices or between a device and an application. Caching: A cache is a region of fast memory that holds copies of data or cache is a temporary storage area where frequently accessed data can be stored for rapid access.  What does Buffer mean? A buffer is a temporary holding area for data while it's waiting to be transferred to another location. It is usually located in the RAM. The concept of the buffer has developed in order to prevent data congestion from an incoming to an outgoing port of transfer.  Computers have many different devices that all operate at varying speeds, and a buffer is needed to act as a sort of te
