Computer Software Program
Software consists of programs which enables a computer to perform certain tasks. Programs are a set of instructions that describe a set of tasks to be carried out by a computer.
Software Programs are also referred to as computer programs. Computers process millions of instructions per second contained in a software program. The sequence of instructions strung together such that when executed, they do something useful, and usually repeatable and reliable. Computer software programs are written by computer programmers and also many a times generated by other programs. A computer software program is loaded into memory (RAM) and then executed, one instruction after another, until termination with success or from a software or hardware error. The operating system loads the computer software program into the memory. There are different types computer software programs. A common software program is the operating system itself. Let us see how software programs work in tandem to achieve meaningful tasks. A computer is initialized in modern PCs by a computer program called BIOS. BIOS is a piece of software stored on programmable memory chips installed by the manufacturer, called the BIOS. The BIOS will attempt to initialize the boot sequence, making the computer ready for higher-level program execution.
A software program is likely to contain a variety of data structures and a variety of different algorithms to operate on them.
Creating a computer software program is the iterative process of writing new set of instructions also referred to as source code. After a computer software program is written, it is tested, analyzed and refined.
A person who practices this skill is referred to as a computer programmer or software developer. The process of computer programming is now referred to as "software development" or software engineering.
Software development is the translation of a user need or marketing goal into a software product. Software development is sometimes understood to encompass the processes of software engineering combined with the research and goals of software marketing to develop computer software products.
It is often difficult to isolate whether engineering or marketing is more responsible for the success or failure of a software product to satisfy customer expectations. This is why it is important to understand both processes and/or facilitate collaboration between both engineering and marketing in the total software development process.
Software engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software.

A major trend in software industry is the Open Source software. An open source software is one whose source code is open for scrutiny and use. The term open source is most often applied to Software program.
The Open source initiative promotes open access to the production and design process commonly applied to the source code of software. This is made available to the general public with either relaxed or intellectual property restrictions. This allows users to create user-generated software content through either incremental individual effort, or collaboration.
Sourceforge is a website which hosts open source projects. It is a popular resource centralized resource for managing projects, issues, communications, and code. Sourceforge provides free hosting to all open source development projects.
Freeware is copyrighted computer software which is made available for use free of charge, for an unlimited time, as opposed to shareware where the user is required to pay (e.g. after some trial period or for additional fuctionality). Authors of freeware often want to "give something to the community", but also want credit for their software and to retain control of its future development. Sometimes when programmers decide to stop developing a freeware product, they will give the source code to another programmer or release the product's source code to the public as free software.
A software developer is a person who is concerned with one or more facets of the software development process, a somewhat broader scope of computer programming or a specialty of project managing. A programmer writes the set of instructions in a computer software program, an analyst writes the classes and architecture, and an architect writes and designs the components, threads and layers of a software application.
