Introduction

Categories of Software Project To: Williams and Smith Accounting Services From: Adam Ashton Date: Friday, 06 January 2006 Re: Categories of Software Introduction In this report I will explain the different types of software that are available, show what their purpose is and their advantages and disadvantages. Hardware and Software Before I start, I will explain the difference between software and hardware as many people mix up these terms. Hardware refers to the parts of a computing system that you can actually touch or see. This means things like the monitor, the keyboard and mouse etc. The computer circuit boards, the printer and all the disc drives are part of the hardware of the system. All these are the things that are manufactured and assembled in a factory. The software of the system means the program's which have to be written by a computer programmer. These things may well be stored inside the computer, perhaps in magnetic form on a hard disc. You cannot actually see the software; it is stored in coded form, as a series of '1's and '0's which only the computer can understand. ...read more.

Utility programs help manage, maintain and control computer resources. These programs are available to help you with the day-to-day chores associated with personal computing and to keep your system running at peak performance. Some utility programs come together with certain operating system. Some examples of utility programs include: * Virus scanning software * Backup software * Scandisk * Disk defragmenter * Deleting, renaming and copying of files Compilers and Interpreters are types of software used to translate the statements from a programming language to machine language. Computers only understand one language, and that is a series of 1's and 0's. It is very difficult to program software in machine language so programming languages that are easier to understand and more like English we're introduced along with interpreters/compilers. Compilers differ from Interpreters in that once a program has been compiled, it is saved in the machine language and then that file can be run over and over without needing to be compiled again. Interpreters do the same job however; it does not save the file in its compiled format - if it ever needs to be run again it must be interpreted (compiled) ...read more.

Conclusion

Once the software has been designed and developed it is then sold to your business. This is called Bespoke Software. This is an application or utility that is designed or tailored for a business or person's specific needs. The benefits of this are that it is designed specifically for you, which should help improve efficiency in your business. However, it is expensive. The Second is to buy the product 'Off the Shelf' this is where the product has already been made and you just buy from a shop ready made. This is cheaper than bespoke software and you can be sure it has been tested by many people but it might not be what you are looking for in a software package. I hope you found my report on the 'Categories of Software' useful in explaining and choosing the right software for your business. There is, however, far more information on the internet on types of software, especially for operating systems.
