Computer Hardware & Software and Emerging Trend & Technologies Yong Choi School of Business CSU, Bakersfield
Computer Hardware • 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
Computing Power • Faster • Cheaper (PC: less than $500) • Smaller • Shorter computer product life cycle
Storage • Price of 1 MB hard drive space • 1983: $300 • ** First PC in 1981 • ** Early IBM PCs have 20 - 30 MB • 1989: $ 2 • 1997: $ .07 • Today: minimal
Transmission • 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
Hardware Trend • More Multimedia Oriented…. • graphics, picture, sound, voice, video clip • DMB • 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
Computer Software • 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)
Two Major Categories of Software Application software – enables you to solve specific problems or perform specific tasks
Two Major Categories of Software System software – handles tasks specific to technology management and coordinates the interaction of all technology devices Two main types of system software Operating system software – controls application software and manages hardware devices Utility software – provides additional functionality to your operating system: Anti-virus, Screen saver….
GUI vs. Command Driven • DOS vs. Windows (i.e., 98, 2000, XP, Windows 7..) • End-user acceptance • End-user training • Productivity • Technical Compatibility • no DOS market after 2002
Demo of Command Driven • Start programs accessories command prompt • Try to delete “sylmis300.ppt” PowerPoint file • dir • cd my documents (not case sensitive but space) • dir (to see available files) • del sylmis300.ppt (don’t forget the file extension) • dir
The instruction “ADD 2 and 5 and assign the result to variable y” written in different programming languages
JAVA • Developed and introduced in 1995 (the newest) by Sun Microsystems • Platform independent • JAVA program can be run on Windows, Unix, Linux, OS/2, and System 7 • Very robust • If necessary, JAVA can handle text, data, sound, and video within one program. • ONLY language for the Internet-based EC • Young, hidden problems, and slow execution speed
SW Considerations • Compatibility with existing software • Outsourcing • Off-the-shelf software
