Introduction to Computer Information Systems Essay Example for Free

Introduction to Computer Information Systems EssayComputer softw ar is no longer a major barrier to widespread character of piano tuner nurture systems.IntroductionTo sleep with about the connection of these topics it is must to know about the link between these phrases as well as the basic concept of these two. Firstly, to know what is calculating machine softw ar and wireless Information systems and then secondly to question their effects upon each other. Computer software is basically some programs or events that are written yet to achieve sure functions by the software engineers. Events are the set of steps that are written and unite to make a program. Now thither arises a question that what is a program then the firmness of purpose of this question is that Programs are basically a set of rules and instructions on the basis of which a computer act to achieve certain functions. To perform a specific set of actions on computers intelligently or normally is the basic need to write a program.Wireless Information systems are basically the systems that employ wirelessly. What is Wireless and why and how question arises then? Wireless, as its name, shows that it means some sort of stockpile of data and discipline among wireless devices without using wires. It contribute be habituated in form of mobiles, organisers, and on large scale Radio is the example of it. Wireless information systems can be the freewheel of mobiles, wireless devices, and networks. The device used for it is basically a device that is installed first and then it can be used. (Wireless network and information processing system, 2008)Certain DependenciesIn case of Wireless information systems, there are certain dependencies. Among those dependencies some of them are very basic and arethe mobility of the user mobility of the resourceExplanationThese dependencies can be differentiated in a way that in case of user mobility it can be in the form of traveling user whereas the c ase with the second dependency is that a network if created among tenfold PDAs and now in this case, if the PDAs are moving. Along with this dependency, there is certain other as well. Just to be a focus on the actual behavior of the wireless and then wireless information systems only two are mentioned here to emphasize the main and most-valuable factors affecting the wireless in general.Important features to consider aboutThere are certain tendencies that are important to know about these systems. According to these, Information systems have to develop first. While developing these systems a software engineer needs to know the protocols (specific rules of dealing on networks) and standard to follow up on them and then to develop finally (Feldman, 2007). There are certain standards that need to follow while considering wireless. In this way, there appears a need to select a standard according to the type of wireless information system. Those standards are as followsIEE802.11IEE802 .11aIEE802.11bIEE802.11gIEE802.16IEE802.16aOpen AirHome basedBlue tooth basedDiscussion afterwards implementation of these steps, architecture to develop a software program is required. When these wireless systems developed then these should vie with the hassle fairly in real time. If an architecture of software program is designed in such(prenominal) a way that it is safe for security flexibility and other issues as well. If technology is implemented selected in an improved way then an information system can work well. If there are leaks in the design and programming tactics and technology implementation then there would be a roofy of leak in the system as well that result in a very bare or drastic problem. In this way, it can say that software programs that developed to resolve a problem need attention in all these metrics to work upon and to get a better result. If there is a better program written by a programmer who is reliable and portable, efficient and of gruelling func tionality then fulfill the better requirement in this case. Whereas if we are talking about the wireless information systems things become more sensitive as we are dealing on real-time and gather a lot of security risks. Thats why after applying and implementing rules and regulations and following the standards will get the better results.The use of wireless information systems is beneficial for the companies and organization in various ways, first of all, it is accessible in nominal resources. It reduces the time and mobility issues problem and enhances the productivity of the organization in this regard.(Wireless Networking in the developing world session 2007)The use of wireless management systems can improve the effectiveness of applying multiple procedures. An output of these procedures when resulted in a ethical form then increased or enhanced the productivity of the organization in a agile manner. Well, reputed industries, companies, and organizations are referring towards these wireless information systems that are very fast growing. Along with all this, there are still new advancements are just coming on the way to increase the quality of the projects or to attain the benefits of the technologies as much as it can be.ReferencesPhillip M.
