Software development is a process of creating, designing ,deploying a supporting software. Also it plays a crucial part in information technology. Software is an set of instruction that tells a computer what to do. It requires certain amount of skills and experience to be able to develop a software. In this Blog we will see the various phases and process in software development.
What does a software developer do?
Software developers will be in the centre stage in all the phases of the software development process ,from scratch to roll out. Some main responsibilities of software developers are,
- Research,design,development and management of software programs.
- Write and implement efficient software code.
- Testing and evaluating new programs.
- Identify bugs and removing them and identifying areas that require modification and developing those.
- Working with clients to find out if the software meet their expectations and make improvements if required.
- Deploying quality assurance procedures.
Types of Software Development
There are many types of software some can be in a single line while some run into a thousands of lines. Also Software operates independent of hardware or the computer systems. In addition to that the software will instruct the computer hardware on what to do and how to do it. The four major types of software are,
- System software
The system software is crucial and designed to run the hardware and internal functions of the computer. System software will also connects with other devices like monitors , devices ,printers and mouse to the computer. In addition to that it also provides functions that are necessary like Operating systems ,utilities,and hardware management systems.
Application software provides functionalities for users to perform tasks. These are also called as end-user program as its helps the user to complete many tasks. For instance application software can help in performing tasks like shopping , gaming and booking systems. Also Application software is developed for a specific purpose to perform a specific task only.
With Programming software programmers no longer need to work from the scratch. Because of the ready-made software available to help them program in different languages. For example compiler,debugger,interpreter etc..
Software programs with built-in codes for a specific devices are known as embedded software. Embedded software programs helps in the creation of software that will controls machines and devices like automobiles ,cellphones etc..
Software development life cycle
The software development life cycle (SDLC) is a methodology to create high quality at a low cost in short time. Also SDLC methodologies supports the software design to meet the business needs. As a result SDLC will help achieve the goals and eliminates the risks .
The six stages of SDLC are :
