18. http://www.webtutorials4u.com –Finally: Definition of CBIS’ and what they do: –CBIS’s are formal systems Fixed definitions of data, procedures Collecting, storing, processing, disseminating, using data –But they are indeed also computerized…so they take advantage of the 4 things computers do well –Are technology-enabled organizational and management solutions to challenges posed by the environment. –Automated support for input, processing, and output of business processes.

19. http://www.webtutorials4u.com Components of a CBIS

20. http://www.webtutorials4u.com Components of a CBIS – Hardware - computer equipment used to perform input, processing, and output activities. – Software - computer programs that govern the operation of the computer. – Database - an organized collection of facts and information, typically consisting of two or more related data files. – People - the most important element in most computer-based information systems. – Procedures - include the strategies, policies, methods, and rules for using the CBIS.

21. http://www.webtutorials4u.com – Telecommunications - the electronic transmission of signals for communications. – Networks - used to connect computers and computer equipment in a building, around the country, or around the world to enable electronic communications. – Internet - the world’s largest computer network, actually consisting of thousands of interconnected networks Telecommunications, Network, and the Internet
