Core Technologies : A Functional Information Technology

A successful IT system is something that is composed of several different functional components to make it a whole. It takes each component to efficiently work so that the entire system runs smoothly. When one or more parts of the system are not properly working it can affect the entire IT system as a whole and render it completely vulnerable to people with malicious intentions. In this paper I will discuss the role of each component in it and shed some light as to why each is needed.

The study of computer based Information Systems (IS) is not just limited to traditional computers and servers, but also includes such devices as:

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

In order for IT System to become active first Computer Programs and Programming must be put in place. Computer Programs and Programming are simple terms an executable set of commands for the computer to perform. A process is an actively running program which may or may not is running in the background. A program running in the background is one that the computer user may not be aware of, but it may be providing useful services such as an ability to connect to other computers. It reads and executes program instructions, performs calculations, and makes decisions (slideshare.net).

There is a mess of servers, switches, switches, and inward equipment firewalls. Each of the association's areas is working with diverse data advances and foundation IT frameworks, provisions, and databases. Different levels of IT security and access administration have been actualized and inserted inside their individual areas. The data engineering framework is maturing and numerous areas are running on antiquated fittings and programming. Additionally, the framework is woefully out-of-dated regarding fixes and overhauls which significantly expand the danger to the arrange as far as classifiedness, trustworthiness, and accessibility.

Hardware refers to the physical components of a computer or other device. An example of hardware could be a printer. Software is the set of instructions that allows a particular program to complete at ask. An example of software could be operating systems, such as Windows, Linux, and Mac OS

Application: A software program that runs on any computer / device that enables the user to perform specific tasks.

In this article Car referenced many sources, one of which includes the University College London, who conducted a five-year research program, that examined computer

Information will only have value if customers can access it at the right times. Availability can be affected by system errors, and malicious attacks as well as infrastructure problems. Availability is ensured by maintaining hardware as well as repairing hardware immediately when need arise. A correct functioning operating system should also be maintained in the environment free of software conflicts. Adequate communication bandwidth should also be addressed as well as preventing bottlenecks from occurrence.

You have been hired by a medium size (approximately 200 employees) widget manufacturing company to do a complete evaluation of their computer needs and make recommendations to them about an information system to support their business. Currently several of their support departments are using manual processes and they wish to automate their accounting and human resources business processes. They also want to harness the power of the Internet in their business.

I. Computer 's are an integral part of our daily lives. Just about anywhere you go, a computer is present. Hospitals, banks, even the gas pump you frequent, relies on computer 's to figure out how much gas you pump, how much it is per gallon, and where to get that money from. As you can see from this line graph, computer 's are in more demand than ever peaking at 350 million sold in a year. (Computer Sales Statistics)

Ben Fifield is a 2011 Olivet Nazarene University graduate and he has happily obtained a bachelors of science in Information Systems. Ben Fifield has gained several job experiences in his past that have been indeed quite impressive. Previously Ben has worked at Olivet Nazarene University with the Information technology apartment. After words he worked at Applied System as System Operation; later, he landed a job with Lincoln College with as a Desktop Support and System Administrator. Now he is a successful network system administrator with a variety of experiences that helped and shaped his present.

Miller Inc. which is in the business of providing data collection and analytics services relies majorly on network security to keep its competitive advantage. This is because the customers that rely on the company's system trust that since there are sufficient security measures that have been ensured, they can store their data securely. Each of the functional models of the system should have sufficient security measures to ensure that complete security of the whole system architecture is achieved. The three functional modules are the backend module, services or operation module and customer access module. The major relationship between infrastructure and security comes in the role they play to ensure that the end user gets the data that they need when they need it and in the best way possible. Therefore for the three modules, there is a need to balance security with the right infrastructure.

3. Give three business examples (not mentioned in the text) of data that must be processed to provide useful information.

Identify and describe the six components of an information system. Which are most directly affected by the study of computer security? Which are most commonly associated with its study?
