DIGITAL CONTENT MANAGEMENT Lecture 2 Content Is data, information or knowledge that is held in a container like a book or website independent of structure or style. Content Management Terminology · Data is a raw value, fact or statistic. Data has no meaning in itself (symbols, signs). · Information is data that is arranged and connected with clear relationships. Data with meaning and purpose. · Knowledge is a collection of information that can be understood and used. Knowledge can be practical and useful. · Wisdom is deep knowledge applied with judgement.

Information: data that is processed to be useful; provides answers to 'who','what', 'where' and 'when' questions. Knowledge: application of data and information; answers 'how' questions. Understanding: appreciation for 'why'. Wisdom: evaluated understanding (forecasting and expectations). Digital Technology Information in the world around us if often: Difficult to measure (e.g. ideas, experience) - Analogue / continuous and variable (e.g. temperature, light, sound) - Computing involves numeric operations. How does computing deal with information that is analogue or not numeric? How does computing translate real world phenomena that will become content to be delivered to our customers? Digits are whole numbers that can be counted. Computers consist of multiple electronic circuits.
The most basic components in each electronic circuit can have one of the following states: - On - Off Real world phenomena can be converted into digital data through these electrical charges! Data that is input into digital computers (like keyboard characters, mouse inputs and touch inputs) is encoded into specific combinations of electrical charges: Off = 0 On = 1 Data and computer program instructions are processed by computers as specific combines of 0s and 1s. Information that is output from digital devices is decoded from specific combinations of 0s and 1s. e.g. Colours in pixels (picture elements) on screens and monitors. e.g. Characters and lines printed by printers.
