Software is the single most important technology on the world stage. The category of software is huge where categories may have subcategories. And this is all because, software is getting used in almost every aspects of human life. Everywhere we go we will find a reason or necessity to have software there.
Before we learn about why software does not “wear out”, lets learn about the state “wear out”. When something is no longer of any use, it reaches the “wear out” state. That is, it can not perform the function it was built for. For example, a printer reaches “wear out” state it can’t print anymore. This doesn’t include the recycling options. One make use of a dead printer to do anything else but printing.
Software is a collection of executable instructions that can be executed by computer devices to perform instructed task or tasks. However, non-executable resources and data can also be referred as software.
Engineering of software is the establishment and use of sound engineering principles in order to obtain economical software that is reliable and work efficiently on real machines.

There are some fundamental steps but as they are fundamental, all these steps may have sub-steps. The fundamental steps are described below with a neat diagram.
Digital Image Processing : An image which has a two dimensional function of f(x,y), where x and y are plane co-ordinates and the amplitude of f at any (x,y) is called the grey level of the image at that point. When the values of these of an image are finite, discrete quantities then the image … Read more
Cross Elasticity of Demand : Cross elasticity of demand occurs when a change in price of a commodity brings the change in demand of another commodity. The cross elasticity of demand for two goods X and Y, is the ratio of the percentage change of quantity purchased of X to the percentage change in price … Read more
