Software is a series of instructions that tell a specific computer how to perform a certain task. This is different from hardware, where the machine actually performs the task and is assembled from parts. In computer technology and software engineering, software literally is all data processed by modern computer systems, which include applications and data. Software is not something that is executed inside a specific machine. A software program may be implemented as a series of instructions on a hardware platform such as a computer server, or in a user-level application such as a mobile application or web browser.
Nowadays, the term “software” refers more to the methodology than to any specific piece of hardware. In hardware systems, a specific set of instructions specifying how the hardware should work is used to create the machine. Software, on the other hand, is more like a set of instructions that tell the computer how to perform a particular task. In computer software systems, the software determines how a piece of hardware should be linked with one another in order to make the desired output.
The term “software engineering” is often used interchangeably with “software engineering”, “software development” and “programming”. Software engineering is concerned with the design, analysis, and implementation of software systems. On the other hand, software development deals more with the creative aspects of software applications. Software application development involves the design, development, and implementation of specific software programs. These are generally used by end users instead of system software engineers.
Application software applications are a subset of system software and are generally less involved and user-level than full-featured system software. Most application software utilizes a form of object-oriented programming (OOP) to allow for code reuse and code modification. A typical computer system can implement thousands of lines of code. As a result, if one part of the program is flawed, it can be fixed separately from the rest of the program, without compromising the integrity of the entire operating system.
The driver software allows the OS to communicate with external hardware devices such as printers, keyboards, scanners, video cards, and digital cameras. This code enables the device to recognize the actions taken by the user, such as clicking, moving the mouse, or playing audio and video games. The term “driver” comes from the term “interface” which refers to the communication between OS and hardware.
Operating system software, or OS, is what actually controls the computer hardware. It controls what the user sees on a screen and controls how the computer works with the hardware. All computer software includes some form of operating system. Basic computer software includes operating systems, security suite, email, anti-virus programs, office applications, and databases for storing information. Other types of software include a web browser, music players, instant messaging programs, and game software.
