Question Answer
SystemGroup of components that interact to achieve some purpose
Information SystemGroup of components that interact to produce information
Information system 5 componentscomputer hardware, software, data, procedure, people (linked through networks that use connectivity to tie hardware, software, data together to make info more accessible & powerful)
Hardwareelectronic components (gadgetry of a computer system, tangible/physical devices used to access system)
Softwareprograms (or applications) that run on computer systems (stored set of instructions that run on your device & specific programs licensed to provide service)
Databuilding blocks of information -> facts & observations
Procedureinstructions that you follow to get your objective (can be formal and documented policies or informational instructions, incl. steps to achieve goal i..e how to log on, save/submit work)
Peopleactors who want to achieve an outcome by interacting with the system
Management information system (MIS)comprise the development & use of information systems to help organizations achieve their goals & objectives; there are 3 key elements (development & use, information systems, goals & objectives)
Development & use + Information systemsdesigned and created by business analysts and system designers at the request of senior managers to solve a problem or meet a need.
need to have an active role in system's development
Goals & objectivesall businesses are organizations but not all organizations are businesses (IS is in almost every type of enterprise, social, non-profit organizations, gov), corporations are legally considered to have many characteristics of humans but are not so need people to think and act for them
IS vs ITIT: refers to methods, inventions, standards, products, refers to raw technology, concerns only of hardware, software, data components of an IS and how these are networked together, will not help an organization achieve its goals & objectives;

IS: refers to a system of hardware, software, data, procedures, and people who product info, when IT is embedded into IS that is when technology within hardware, software, and data are combined with people, procedures that IT becomes useful
Real difference between IS and ITIS includes people
Information and communications technology (ICT)provide products and services that other industries rely on to get their work done; 'hidden' industry -> 3% Canadians workers
How do successful business professionals use IS?- knowing how to use device and applications
- understand the technologies and businesses well that you can identify opportunities for innovation through technology and understanding the risks
- individuals need a core set of skills incl: technical skills, specific technology & industry experience, satisfactory communications & other business skills
ICT user industries comprisecompanies, organizations, public sector bodies that use ICT in their operations - all the industires other than those companies in the ICT sector
Factors affecting IS1. Moore's law (an observation that noted that density of circuits on an integrated chip was doubling every 2 years, proved to be true for almost 50 years, power of computers has increased over the past 50 years, trend shows no sign of slowing down so computering power will continue to increase allowing entrepreuurs to plan new products & services),
2. network effects and lock-in of certain technologies (where the value that is received increased significantly as the # of users increases),
3. general shrinking of device size (tied to Moore's law),
4. tendency for ubiquity (exist everywhere),
5. adoption of location-based services facilitated by GPS technology and mobile use
