Key Process Areas (KPAs): The KPAs describe those software engineering functions that must be present to satisfy good practice at a particular level. Each KPA is described by identifying the following characteristics: 01. Goals: Goal is the target of a project or the overall objectives that the KPA must achieved. 02. Commitments: Requirements that must be met …
Software development is totally a layered technology. That means, to develop software one will have to go from one layer to another. The layers are related and each layer demands the fulfillment of the previous layer. Figure below is the upward flowchart of the layers of software development.
Steps of Software Development: A software development process is a structure imposed on the development of a software product. Software development is a detailed process. It includes many steps which is dependent on the software to develop. But the main steps of a software development process have been discussed below.
Software, by definition, is a collection of computer programs, procedures and documentation that performs different tasks on a computer system. There are many types of software and this is increasing with the development of technology. Some of these types are described below.
It is often said that Software is engineered or developed but not manufactured. Although some similarities exists between software development and hardware manufacturing, the two activities are fundamentally different. Software is a design of strategies, instruction which finally perform the designed, instructed tasks. And a design can only be developed, not manufactured. On the other hand, design is just a material of hardware.
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.
