Computer Software All computer systems consist of two major components,namely,hardware and software. ■ The hardware refers to the physical equipments that are necessary for performing various operations, such as reading and processing data,storing results and providing output to the users in a desired form. The software refers to a set of computer programs that are required to enable the hardware to work and perform these operations effectively
Computer Software ◼ All computer systems consist of two major components, namely, hardware and software. ◼ The hardware refers to the physical equipments that are necessary for performing various operations, such as reading and processing data, storing results and providing output to the users in a desired form. ◼ The software refers to a set of computer programs that are required to enable the hardware to work and perform these operations effectively
Computer Software A computer program is basically a set of logical instructions,written in a computer programming language that tells the computer how to accomplish a task.The software is therefore an essential interface between the hardware and the user. We can say that software gives life to the hardware and therefore,the software is popularly referred to as the "soul"of the computer system while the hardware as the“heart

Types of Computer Software A computer software performs two distinctive tasks: (1)The first task is to control and coordinate the hardware components and manage their performances (2)The second one is to enable the users to accomplish their required tasks. The software that is used to achieve the first task is known as the system software and the software that is used to achieve the second task is known as the application software. While the system software is essential for a computer to work,the application software is the additional software required for the user to perform a specific job
