3Analysing

**Definition of Analysing**
Analysing is a process that involves the data being interpretted so it can be transformed into data.

**Hardware used for Analysing**
Harware that is involved in the analysis of data includes the CPU (Central Processing Unit) for processing and storage. Analysis requires fast processing speed to allow for many calculations and large amounts of primary and secndary storage. Large amount of storage are needed to recieve and retain data over a period of time. Fast processing is possible with large amounts of primary and secondary storage. Fast processing is needed to complete calculations required, performed by the CPU. The purpose of analysing is to give meaning to the data. Primary storage is the main memory directly accessible by the CPU (ROM), and secondary storage is the external storage (RAM), such as CD-ROMS, USBs, etc. Fast processing is necessary to complete calculations required for analysis, which is performed by the CPU. Applications requiring complex analysis use parallel processing, which is faster than using one CPU.

Non-Computer Tools
 * Searching: manual filing systems to retrieve documents
 * Speed depends on accuracy
 * Hard to keep up-to-date
 * Simulations: involve using mathematical processes in which a set of rules, relationships and procedures are specified
 * Range from using pen and paper models to complex interactive computer systems
 * Eg. Could be used for experiments instead of using rare materials or expensive equipment

- **Privacy:** eroded by linking databses for analysis. A person leaves a electronic trail of their life behind via. credit cards etc. so if this data was to be analysied and compilied it would create a accurate image of the person, their likes and spending habits, this is known as 'data-mining' or 'data ware-housing' and is used by organisations to target people.=====
