Analysing

It is the process that transforms data into information. However, the data are not altering during the process. It is also a process that’s look for pattern or meaning in data. Hardware for analysing: RAM (Random Access Memory), ROM (Read Only Memory
Software for analysing: search key, logical operator.Non-computer tools for analysing: Telephone book, wind tunnel
Social Issue: Unauthorised analysis of data, erosion of privacy from linking database for analysis

It uses different kind of hardware to physically gather all data in this world. The reason of people collecting data is to analysis then to translate it to a monitor .Therefore, it can be displayed as useful information to let people to read or use. The decisions that involve in collecting are 1.What to collect it? 2. How to collect it? 3. Where to collect it? Through different types of hardware and software, people can collect data from the world. The Hardware for collecting is keyboard, voice recognition, document scanner and bar code readers. And the software for collecting, such as keystroke, a web data entry form, spreadsheet, web browser, sound recorder. For the non computing tools of collecting is handwriting on paper, data entry form layout, interviews, surveys. However, the process of collecting would bring up some issues. Socially, privacy, acknowledging the data source, data accuracy and the ergonomics of collecting data.
