COMPUTERS AND SOFTWARE
A computer’s operating system and various activities are carried out by software, which is a collection of instructions, data, or programs. In contrast, hardware, quite different from software, refers to the components that make up a computer’s physical structure. Software thus becomes a crucial part of computers. Software can be said to be the soul of the computer. An application, script, or program that runs on a device is referred to as software in general usage. Software can be viewed as the changeable component of a computer, whereas the hardware, unlike software, is always present. Find the basic information about software in this article.
TYPES OF SOFTWARE

Application Software:
Application software, the most prevalent kind of software, is a set of computer programs that carry out a particular task for a user or, in some situations, for another application. Applications can be standalone or comprise a collection of programs that operate them on the user’s behalf. Office suites, graphics software, databases, database management software, web browsers, word processors, software development tools, image editors, and communication platforms are a few examples of contemporary applications.
System Software:
These software packages are made to run the hardware and application software on a computer. The actions and features of the hardware and software are coordinated by the system software. Additionally, it manages how the computer hardware functions and offers a setting or platform in which all other software can operate. The OS, which controls all other computer programs, is the best illustration of system software. The firmware, computer language translators, and system utilities are more examples of system software.
Driver Software:

This software, also referred to as device drivers, is frequently regarded as a kind of system software. Device drivers manage the peripherals and devices linked to a computer, allowing them to carry out the activities that are unique to them. A device driver is required for the operation of every connected device to a computer. Examples include any nonstandard hardware, such as specialized game controllers, that comes with software, as well as standard gear, such USB storage devices, keyboards, headphones, and printers, that is enabled by software.
Middleware:
Software that acts as a middleman between two different types of application software, between system software and application software, or between the two is known as middleware. Microsoft Windows, for instance, can communicate with Excel and Word thanks to middleware. Another application on a computer running one type of OS can utilize it to request remote assistance from an application running on a computer running a different OS. Additionally, it makes it possible for more recent programs to communicate with older ones.
Programming Software:

To write code, computer programmers utilize programming languages. It is possible for programmers to create, write, test, and debug other software programs using programming languages and tools. Compilers, debuggers, interpreters, and assemblers are a few examples of programming software.
Designing and implementation

Project managers utilize a framework called the software development lifecycle to outline the steps and duties involved in creating software. The planning stage of the design lifecycle is followed by a need analysis of the users of the program and the development of specific requirements. The design phase, which follows the first requirements analysis, seeks to define how to satisfy those user requirements.
Following the conclusion of the development phase, software testing takes place before the implementation stage. Any actions necessary to maintain the system are completed during the maintenance phase.
A description of the software’s structure, data models, interfaces between system components, and possibly the algorithms the software engineer will employ are all included in the software design.
User requirements are converted during the software design process into a format that computer programmers can utilize to code and implement software. The software engineers create the program design iteratively, incorporating details and making adjustments as they go.
