Software has become a critical part of our lives - it is as critical to computers as blood is to humans. Basically software is the entire set of programs, procedures, and routines associated with the operation of a computer system, including the operating system. It is an ordered sequence of instructions for changing the state of the computer hardware in a particular sequence.

So you want to know about how to write software. Well, Software is written by programmers in a number of programming languages such as a Java platform. Traditionally software is developed in a closed and commercial environment. It is developed according to the Design Specification. The preparation of the software is simplified by the use of 'wizards' that walk the user through the creation of the presentation. There is also some documentation done before hand. This document is developed to ensure that a sufficient base is provided for the software design.
Depending on the magnitude of the project Inspections are integrated into the development process, and the software is inspected while being developed. inspections are carried out on software that have been completed by their author but not yet tested, reviewed, or otherwise approved or baselined. They are used to judge the quality of the software work product, not necessarily the quality of the people who create the product. Some Inspection materials include the software to be inspected, the inspection announcement, the preparation log, background information, and checklists.
Furthermore, the inspection will look at not only how software is designed, developed and tested - but also at how the vendor is able to leverage the ecosystem. It will also be checked to see if it is usable by the users for which it was designed.
Generally you can develop write software on windows or Mac OS but some software is strictly developed on Linux and as such deploying on Mac OS and Windows can be a serious frustration. This often comes with some documentation, which is to operate and maintain the software. It is developed and maintained according to the project's defined software process.
Other than focusing on how to create computer software, it is also important to know that software products may be developed for a particular customer or may be developed for a general market. So before you buy a book on how to create simple software for windows or something like that, you need to know why you want to learn about how to write software or how to create computer software.
It does not just end with creating the software but you should know that software costs more to maintain than it does to develop. You need to have tools to support later activities such as programming, debugging and testing.
Depending on the size of your planned project, you may have to organize some real money before you embark on this journey especially if you are going to spend some time trying to answer the question, "how is software created' - I mean learning about development before you start the development process itself. Costs vary depending on the type of system being developed and the requirements of system attributes such as performance and system reliability. Roughly 60% of costs are development costs, 40% are testing costs.
There are a number of easy to use application development tools that do not need much investment in to learning and also maintaining the software. Do not be locked-in with some applications that you will find hard to use and may cost you a lot of money. I usually say if you have the question "how is software developed" lingering on your head then take the time to learn by getting your hands dirty with easy to use application development software. You can find some trial software online that will not cost you anything to download and try out for a few days.
