Yong Choi BPA CSUB

 An Information System (IS) is interrelated components to collect, process, store and distribute information to support mainly decision makings in an organization.  Information technology (IT) describes the combination of computer technology (hardware and software) with telecommunications technology (data, image, and voice networks).  CBIS vs. Manual IS  CBGIS vs. Manual GIS

 Information Age ◦ Bill Gates (how much rich?), List of GDPhow much richList of GDP ◦ Major TANGIBLE product of Microsoft ◦ Information age phenomena  Population of “facebook.com” : 800 million active user  US: 310 million

 Post information age  IBM WatsonWatson  MOOC: massive open online coursemassive open online course ◦ Udacity Udacity ◦ khan Academy khan Academy

Functions of an GIS

 Comprehensive term for all the physical parts of a computer  Tangible: things that you can actually touch and feel ◦ disks, monitors, keyboards, printers, boards, speaker, and chips.  Falling price of HW ◦ Technical driving force of the Information Age

 Faster  Cheaper (PC: less than $500)  Smaller  Shorter computer product life cycle

 Price of 1 MB hard drive space  1983: $300 ◦ ** First PC in 1981 ◦ ** Early IBM PCs have MB  1989: $ 2  1997: $.07  Today: minimal

 One hour teleconferencing ◦ 1985: $100 ◦ 1998: less than $10 ◦ Today: minimal (i.e., skype)  Internet dial-up service ◦ 1997: AVG. $40 ◦ DSL: less than $15

 More Multimedia Oriented…. ◦ graphics, picture, sound, voice, video clip  Smaller, Smarter…. ◦ Tablet PC (ipad), smart phone….  More powerful ◦ Traditional: single CPU vs. all tasks ◦ Parallel: multiple CPUs vs. many tasks ◦ Massive parallel (process many tasks simultaneously)  many networked CPUs vs. many tasks

 Intangible: untouchable ◦ Written in various computer program languages ◦ C++, Java, VB.NET....  Set of instructions that hardware executes to carry out a specific task for you  Changing of SW price  Availability of various SW tools ◦ Technical driving force of the Information Age  More important than HW ◦ Y2K ◦ WorldCom (now MCI)
