Filtering data can save the business time and money. Data can also be received from outside the organisation - such as sales orders, People People are involved in the capture, processing and the inputting of data in a organisation. They are used for sourcing data that the company needs for their information system. However, an example of complex processing could be the likes of a computer performing many calculations and making assumptions about missing data. Spreadsheets are also a good way to find stored values and observe the effects for future prediciations and use the what-if analysis.

If the organisations information systems were to be breached it could mean many peoples personal data would be at risk. Closed systems usually refer to when there is a set output, which only a few formats of output can be chosen from; this system is usually easy to use and aims at presenting information to management. Telecommunication Telecommunication very important in an organisation that uses information systems. The Hardware a business will need are things like routers, servers etc. As part of human resources this device will help employees on the move around the store, monitoring their activity and feeding back how active they are in their role.

There is no point in capturing information that is not relevant as this information will have nothing to do with the subject engaged in. Information that are shared through the internet have a very high risk in getting hacked, stolen or intercepted, the information must be encrypted before they are sent through the internet to prevent the data being hacked. Although hardware plays a role in the technology that could benefit Nexus in the long term, but also software. Closed and Open System The difference between closed and open systems is that closed systems do not interact with any of the environment and do not handle external variables as well as open systems. To find the right locations for the roadshow I checked the Nomis website in order to see what data they had in regards to the population of young people in each location who were in employment with professional occupations. Data should be stored at the most detailed level possible. These functions are often enclosed in a control or feedback loop which allows the input of a system to be changed if the system output may affect it in the future.

For example using others log in to access their account and installing virus to the computer, will destroy their files on the computer. Processing Processing converts the data into the information needed by the user. The employee receives the data from where it was created and is then checked a validated to make sure when the data is transformed it is accurate. Health and safety plays a part in keeping information secure in the sense that if the employees are in no harm and working in a good working environment then they are going to work more effectively and efficiently at their work space, and are able to work to their best ability. For example the management of a school will only allow the technicians to update the systems. Card readers, chip and pin and also credit card details must be secure during transferring data information.

If a backup is taken however, it would be wise to store a copy of this backup at another geographical location, in case there was in fact a natural disaster or any other form of disaster to lose the information, so that the backups do not get lost or destroyed also. So the source in which you find the information must be believable to make interested in the topic. For Matlin insurance this will be very useful for departments such as Human Resources and Marketing. Closed systems have a fixed setoff outputs. Organisations that provide their own web server have often strict rules to what can be posted on the server. This creates the dilemma that not all workers will be working sufficiently if there are not enough computer machines for one per person. Neither you, nor the coeditors you shared it with will be able to recover it again.

This information will be accurate as it comes from a trusted source, dealing with governmental statistics. The reason why we are looking at software utility is that not everybody knows what it is and do not know how software utilities can help your computer from getting viruses, etc. The information is passed on to the senior management. It should also be compatible with the software the organisation will use to process the data. You can also see how information flows between these lower departments, and how they share information.

However, as mentioned above, although being valid and accurate the locations which were less populated with young professionals was not really relevant to our search, as we want to aim our roadshow to as many people as possible — by going to less populated area limits us to target smaller groups of people. Computer data is basically a bunch of ones and zeros as it is made up of binary code, and because of this it means that all computers are able to create, process, save and store this information without losing any quality overtime no matter how often it is used. To receive information the user will need to know how believable the source of information is. Neither you, nor the coeditors you shared it with will be able to recover it again. This would become useful if Nexus had to go out and do talks or presentations about the work they do to other companies or customers for example, allowing them to access the necessary files to present to other people.

Idea 2 Idea 3 Idea 4 Data Data is raw facts and Figures, a data is an information that has not yet been given its context. As you can see I have singled out the top six locations with the highest population in terms of young people in a professional occupation at the time, the highest being Westminster with over eight thousand, and the lowest of the six being four and a half thousand people. Opello can benefit off the data they receive from each department, by saving costs. Organisations need valid information to help them to keep track of their stocks. Processing The processing of data is where the information is turned into knowledge Output Outputted information can be displayed in many forms.

In my case, I have chosen the top six populated locations presented to use by filtering the accurate and valid data set, which presented us with more a more accurate outcome, showing us locations which we are more likely to attract a wider audience of people which we are aiming to target our roadshow at. With there being a server in the office, the employees should have a fairly easy job to recover any lost data from a local machine if they have backed everything up to the server. Features There are five main features of a standard information system: data, people, hardware, software and telecommunications. Computer Misuse Act 1990 is an act that is designed to frame rules and control over computer crime and internet fraud. Small and simple management information systems can be made using general-purpose application software that has already been programmed.
