System Software is a set of programs that control and manage the operations of computer hardware. It also helps application programs to execute correctly. System Software are designed to control the operation and extend the processing functionalities of a computer system. System software makes the operation of a computer more fast, effective, and secure. Example: Operating system, programming language, Communication software, etc.

Computer hardware and software

Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system hardware. This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software. Practical computer systems divide software into three major classes: system software, programming software and application software, although the distinction is arbitrary, and often blurred. Computer software has to be "loaded" into the computer's storage such as a hard drive, memory, or RAM. This involves passing instructions from the application software, through the system software, to the hardware which ultimately receives the instruction as machine code. Each instruction causes the computer to carry out an operation -- moving data, carrying out a computation, or altering the control flow of instructions.

Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit.

Hardware refers to the physical, tangible computer equipment and devices, which provide support for major functions such as input, processing internal storage, computation and control , output, secondary storage for data and programs , and communication. A computer system is a set of integrated devices that input, output, process, and store data and information. Computer systems are currently built around at least one digital processing device. There are five main hardware components in a computer system: Input, Processing, Storage, Output and Communication devices.
