Software is simply a series of instructions which tell a particular computer how to perform a certain operation. Generally this is compared to hardware, where the machine actually does the work and is constructed from various parts. However, software is usually created for specific purposes and is integrated into a larger program. A good example of software is a web browser. The different components include the Web browser itself, its HTML coding and various scripts to allow it to function properly.
So what is it that makes computer software so very useful? Well first of all, the whole point behind most software is that it takes the hard work out of some tasks. For example, with web browser you might sit down at your desk and add new tabs or search for something and spend hours in front of the screen, only to find out later that the information you were looking for was already there in your screen. With software this is never going to happen.
Of course, some applications software can be used on both a hardware and a software platform. This is not as common however, because it requires much more programming knowledge for the hardware side of things and it requires that the same program be compatible on both platforms. However, if an application software is written for a specific operating system, then it is possible to run the same program on both hardware and software platforms. So, an example of this is a medical software which works with both Windows and Mac.
Programmers and developers also like to use computer software which is available as freeware. This means that the software can be used for free, but if it is altered or used in any way that infringes on any copyright, then the developer who wrote it has no obligation to give back to the owner. Many people think of freeware as one-off downloads. In fact this is true of many freeware applications. However, there are also lots of freeware computer systems software which have commercial values.
Freeware is not suitable for everyone. For example, it may contain adverts for other products, and in doing so the owner of the adverts might have a financial gain from it. When using freeware, you must always remember that it is just that – free. You should not use it to create malicious programs such as viruses or spyware. Anti-virus software is also very useful to help you make sure your computer systems software is up-to-date and will stop the risk of virus infection.
When looking at computer science curriculum a student should look out for a couple of different types of reference books. The first piece of software engineering that they should look for is a good first piece of reference, which is usually a manual for a scientific procedure. The manual will help them identify the problem, explain what they are trying to achieve, and then describe the methodology. The second piece of software engineering which is quite important is citations. Citations are used to show that an author has used a scientific method or concept.
A good citation needs to be correct and complete. It also needs to have a description of the data which was used. When checking out free software programs for computer systems, students should check to make sure they can easily find a citation needed for the assignment. There are many free software programs which supply data citations in the form of HTML citations.
