2. Analysing Analysing is the interpretation of the data. It involves examining the data and giving meaning to it. When data has been ordered and given meaning by people it is called information.

3. Hardware Hardware requirements for analysing depend on the type of analysis. When analysis involves large amounts of data or complex simulations, the hardware must perform a large number of computations very quickly and with a high degree of precision. If the simulations are complex, such as in scientific applications, then a supercomputer or mainframe may be required. Analysis depends on the storage and processing capabilities of the information system. Hardware requirements for analysing depend on the type of analysis.

4. Large amounts of storage are needed to receive and retain data over a period of time. If the primary storage (memory) and secondary storage (memory) and secondary storage (storage) resources are abundant, then fast processing is possible. Large amounts of storage are needed to receive and retain data over a period of time. If the primary storage (memory) and secondary storage (memory) and secondary storage (storage) resources are abundant, then fast processing is possible. Fast processing is needed to complete the many calculations often required for analysis. This is performed by the central processing unit (CPU). Applications requiring complex analysis use parallel processing. This is the simultaneous processing of instructions using multiple processors or CPUs. Parallel processing is much faster than using one CPU. Fast processing is needed to complete the many calculations often required for analysis. This is performed by the central processing unit (CPU).

Participants use a range of software applications to analyse image, audio, video, text and numeric data. Searching is the process of locating data and information. Most software applications have a ‘Find’ or ‘Search’ command. The user types in a string of text or numbers and the software examines the data to find a match. A query is a search of a database for records that meet a certain condition. There are three methods of entering a simple query: selecting a menu option, using query by example and using a query language. Searching is the process of locating data and information.

Modelling and simulations are used to make predictions and examine decisions concerning real situations. A model is a representation of some aspect of the real world and a simulation is the use of that model.

The software allows the user to make changes to one item of data and observing the effects on other items. ‘What-if’ predictions are a powerful feature of spreadsheet software.

8. Non-computer tools Information technology is not always a suitable tool for analysing data. It is often necessary to compare and contrast computer and non-computer tools for analysis on the basis of speed, volume of data and cost. The following are some of the non-computer tools used for analysis. Information technology is not always a suitable tool for analysing data.

Unauthorised Analysis: Data occurs when people gain illegal access to an information system. The theft of information and its subsequent analysis is a major concern for any organisation. Unauthorised Analysis: Data occurs when people gain illegal access to an information system. The theft of information and its subsequent analysis is a major concern for any organisation. The incorrect analysis of data results in inaccurate information. If data has been poorly organised or an inappropriate model used to represent a situation, the analysis will be wrong.
