                                                                       (Melnichuk, 2022)                                                              

  What is software?                                                    

A set of instructions, data, or programs used to control computers and perform certain activities is referred to as software. Applications, scripts, and programs that operate on a device all are referred as software. Software can be compared to the variable part of computer, whereas hardware is invariable part(Rosencrance, 2021).

Types of software

  • System software
  • Application software 
System software
System software is software that directly controls computer hardware and offers basic functionality to users as well as other applications in order for them to function properly. It manages the internal workings of computer as well as external hardware such as monitors, printers, storage devices. It is similar as interface between hardware and user application. Human readable language is converted to machine language by system software and vice versa. 

Application software
  Application software is software that performs particular functions or provides functions that go beyond the basic operation of a computer. Additionally, application software is created to help end-users to do a certain task. It is designed to fulfill the end-users requirement.

Software Development

The process through which programmers create computer programs is know as software development.
Software development is a set of computer science activities concerned with the creation, design, deployment and maintenance of software. Software development is the life cycle of procedures that is constituted of a well-segregated structure imposed for the production of software that may trend in the market(GeeksforGeeks, 2021).

Steps in software development process:

                                                              
                                                                            
                                                                                                (Pham, 2022)


Gathering and analysis
In the first step it is important to gather the general ideas for any software and learn about and document the needs of users. Then the data is analyzed to ensure what the application is supposed to do and its requirement(Pham, 2022).

Design
The system designs aid in the specification of both hardware and system requirements. It also aids in the definition of a system's overall design in software architecture.

Coding/Implementation
After the design documentation for the software to be created, the work is divided evenly into numerous parts and modules. In this step actual coding starts. The production of excellent codes by the developers is the main focus of this phase. This is the most time consuming step of the entire process.

Testing
This is the important step for developers as if any errors are discovered in the codes, then the coding process should be repeated and the cycle will continue until the project is completed. All types of functional testing, including integration testing, unit testing, system testing, acceptance testing and non functional testing are completed in this step.

Deployment 
After the coding errors are eliminated the deployment stage starts. The initial code is made available to costumers which is known as Beta testing. If any changes are required or the faults are discovered during implementation then they are reported to the team. After all the changes have been applied and the bugs are fixed then the final dispersal or deployment is set.

Maintenance
When the software product is fully put on the market after the completion of all the steps successfully it must be kept operating and maintained. It may be necessary for concerns to resurface from time to time to keep the system up to date with the latest operating system patches(Pham, 2022).

Welcome Post

  My name is Fizu Rijal. I belong from the beautiful country Nepal which is blessed by the gorgeous mountains of Himalayas and the extensive vegetation and foliage of Terai and Hilly regions. Talking about myself I completed my Higher Secondary School from National School Of Sciences in Nepal. I have always been interested in learning computer science since my school days, where we were taught BASIC since then I love programming. The dream of pursuing degree in computer science is driven by my deep interest and curiosity about software development and various computer applications. Another important reason is the scope of computer science which provides a great career opportunities all around the world. Computer Science is a growing field and I believe learning computing will make me more competent so   I chose to study it. Besides engaging myself in computer work, I also love travelling different places, learning and knowing more about people, their cultures, and their way of living.

Research Essay: Main Body

  The ultimate goal of software development is to build high quality, maintainable software in a timely and cost-effective manner. This is only possible if the processes for producing it is matured. In this matured process, it should be possible to estimate how much time and effort will be required to complete the end result ahead of time. When building a software product, software development companies use a method. The framework that is utilized to organize, design and control the process of constructing an information system is referred to as this methodology   (bartleby, 2022) . The standard process of software development completes in six steps which includes gathering and analysis in which the general ideas for any software is gathered and the data is analyzed to ensure what application is supposed to do. Secondly, in the design step it helps in the definition of a systems overall design in software architecture. Along with that coding and implementation comes which is the most t
