Difference between System Software and Operating System
A software is a set of rules or instructions that are given to a computer to perform some function. Basically, software is classified into two types: Application software and System software. Application software is additional software in a computer which is used to perform a specific function. Users has a direct access to this application software and this software is not mandatory in a system. We can use system without this application software.
System software is the main software of a computer that has a direct access to the system’s hardware. It takes care and monitors all the other functions of a computer. It manages computer resources. A computer doesn’t work without system software. Operating system is a system software that acts as an interface between the user and system’s hardware.
What is a System Software?
System software also known as system program, is a set of computer programs that are used to operate various hardware components that are connected to the computer system. It acts as interface between the user and application software. This is the main component that controls all the internal working of the system. It acts as a platform to run other application software.
System software are classified into the following types.
Operating system − Operating system is a software that sits in between the software and hardware of the computer system. It acts as a mediator and provides the interface to interact with them. Operating systems are used in computers, laptops, TV, mobiles, etc.
Device driver − Device driver is a software program that manages all the external devices or hardware components that are connected to the computer. It doesn’t have a user interface. It is present in between the operating system and hardware and allows OS to use hardware whenever the request is made. Usually, it is written in C or C++ languages.
Utility software − Utility software maintain the smooth functioning of the computer. It assists the functioning of the operating system, and provides necessary environment that is required for running OS. Utility software comes along with operating system package. They can also be installed separately. Antivirus software, file management tools, compression tools, disk management tool, disk cleanup tool etc., are all examples of utility software.
What is an Operating System?
Operating system is a system software that acts as a mediator between the user and hardware. It manages all the hardware components. It provides an environment for the user to interact with various applications, execute programs and use hardware components etc., OS is the essential part of a computer system.
OS is the first program to run when the computer is turned on. BIOS will start running the operating system once computer is started. It manages other application software, hardware devices, allocates memory, storage management etc.,
The main functions of an operating system are −
Types of Operating Systems
Following are the different types of operating systems −
Batch operating system − Allows multiple users to use it at the same time. But there are no connections between the users. The OS doesn’t directly interact with the hardware. There are certain operators between the OS and hardware.
Time – sharing operating system − Each task is given with certain amount of time to execute. Once the time is completed, the control is shifted to the next task.
Distributed operating system − Here, all computer systems are connected to an OS. Each computer has its own memory and CPU and they are all connected to a single operating system. Connected computers can access various files from that network which are not actually present in them.
Network operating system − Here computers have their own operating system and are connected to a common server
Real-time operating system − These OS are designed to perform specific tasks in a given time limit. They are used in missiles, airbags etc.,
System Software vs. Operating System
The following table highlights the major differences between System Software and Operating System:
System software controls all the hardware components that are connected to the computer
Operating system is a system software that acts as interface between user and system’s hardware
It is loaded into the memory whenever it is required
Once the system is on, it resides in the primary memory until the system is turned off
It is run when the call is made
It is run continuously
System software is of the following types:
System software manages the entire computer system
Operating system manages system along with software
Windows, Linux, antivirus software, compressors, USB drivers etc., are examples of system software
Windows, Mac, Linux, Unix, Android, etc., are all examples of operating system
System software is a software that manages the hardware components of the computer system. Operating system is one of the system software that manages the system’s hardware and also acts as interface between user and hardware. Operating systems runs various other software applications.
