Changing computing

The changing world of computing


The world of computing is an ever-changing one. But what is most significant, it is here to stay. Some people invent solutions to problems that seemed impossible to solve before. And they are right. Some people continue to make improvements out of an Old West that may look macro but soon will be technologically obsolete. While others seem to be doing the impossible and are getting it right. Well, they are not doing the impossible, they are making improvements.

Software is the answer to any problems that cannot be solved by a hardware. It is the one which is adequate in perform tasks with high accuracy and with small size. Three words best describe software: It is precise, It is reliable and Most of all, It is easy. Take the above mention software for instance, which is a computer storage backup tool.

Over the years, software developers have made changes to the original software. While some of the changes are useful, some are surely acts of art. It depends on the user how he/she perceives the software and how the new one works for him.

Three generic qualities of software and which are motto of software development are:

Propriety implies that the software should perform the tasks as intended without any error. It should be error free and should neither be easily damaged, nor the user should face any problems while using the software. Abundance implies that the software should be able to perform all the needed tasks and that should be easy to use. The accessibility implies that the software should be capable to be used from any type of computer system and also any sort of hardware.

While making the changes in the software, the application programmer puts in it with minimum human intervention. When the first version of a software is released, the second one is usually perfect and more comprehensive than earlier version. The second one is usually geared to all the needs of the user and all the minor details can be fine tuned. That is the reason for the release of the subsequent version. All these versions of the software are cumulative and each one has something new to offer.

Software Development in three forms:



Off-the-shelf Software

External software is obvious, having its own separate storage space. In-house software on the other hand, although being economical, has many problems associated with it. It also puts extra pressure on the software vendor to ensure that the software is up-to-date with the hardware. Since hardware does not stay the same, but computers, the software vendor usually has to assume the responsibilities of software vendors as well as the hardware vendors. Additionally, the In-house software are usually very expensive.

Off-the-shelf software on the other hand is a more common practice. It finds use in most office environments as there are many users who access office productivity tools. These tools are mostly driven by productivity and not by the users. Typically, these office programs are registry dependent and any changes in the registry can affect the productivity of the software. In addition, most of the off-the-shelf software is proprietary which means that the software cannot be modified and it may or may not be original. Although it is not illegal per say, it is not encouraged either.

Finally, there’s the last option: low-cost, entry level freeware or shareware.

I seriously simplify this article. These softwares are of a low cost as in no monetary cost and the company that produces the software can obviously earn some money through this. However, this type of software may have a limited audience and may never be fully developed. Shareware on the other hand, are usually either low-cost or free. This type of software may be lacking in enterprise features and may not fully develop all the capabilities of the low-cost programs.

Freeware is also related to Open Source. See, a freeware program is an “open source” program in that it allows anyone to modify the source code. Of course, anyone can make changes to them and redistribute them, but the community of users has stipulated that certain goals, intentions and purposes cannot be changed. An example of such a freeware program is the operating system GNU, along with its complete source code, is available for anyone to use and modify. Another example is GIMP which is also free to use.
