Data
Data needs to be imputed into an information system so it can be managed and processed. Data has to be stored in the most efficient way, like keeping the same type of data together. The data stored must accurate, valid and fit-for-purpose so that when it is outputted as information, the information that is used is correct and won’t impede the company’s work.
People
People are involved in obtaining data and processing it to create information for purposes relevant to the business. Staff need to have the correct training and skills to get the most out of information systems and make them effective employees.

Telecommunications
Most information is shared between different departments in a company over the internet although this can cause multiple security issues and can breach the Data Protection Act. This issue is often resolved by companies as they have an intranet where they can transfer data between departments and be protected by the company’s security system. Overall, the telecommunication system must be effective to transfer data safely and reliably.
Input
Input is the data that is entered into the information system detailed data that is stored and processed creates the output and the user must specify to the system what sort of analysis they want the system to do All data and information must be stored in the most detailed way possible that the system can provide. IT department of a company may choose to store summarise of data so that that data is easy to use and is consistent – thus when it is used it is more reliable. …show more content…
There are a wide range of ways in which data can be processed, some simple some complex. Simple processing would be simply adding up the number of items sold by the business by a variable, such as the store location, the product or the time or date. Complex processing is the function of a computer performing calculations and making assumptions about any missing data to create the information from the data available. processing takes raw data inputted into the system and uses it to produce information suitable to the user’s purpose for it.
Output
Output can be in 2 separate forms, graphical and textual. Graphical is often used to view information on a larger scale and presented as charts, graphs, diagrams and pictures. Graphical output makes it easier to understand trends in a company and can be used to highlight changes in the company (e.g. a drop in sales). It is most commonly used when presenting data to management as it is easier to follow.
Textual is used to view the information on a smaller and more detailed scale, to do this it’s presented as charters, text or numbers. This is used when the user must analyse detail and know specific information. Both formats can be used collectively to represent information – graphical outputs can show important figures as a whole and textual outputs can be used to go into more detail on a specific area
