Computer Hardware The tangible elements of a computer system The components that store and process data, perform calculations Input devices like the keyboard and mouse allow users to enter data and commands. Storage and processing components consist of the hard drive and other storage components like flash drives.

Types of Computers Desktop (Personal) Computers Server Mainframes Supercomputers Notebook Computers Handheld Devices

Computer Software Programs, routines, and computer languages that control a computer Operating System –Windows Operating System –Mac Operating System Application Software –Microsoft PowerPoint –Quicken

Computer Networks THE INTERNET Local Area Networks (LAN) Wide Area Networks (WAN) Wireless Local Networks Intranets Virtual Private Networks (VPN) Voice over Internet Protocol (VoIP)

Security Issues E-Crime Computer Viruses –Worms –Trojan Horses –Spyware

Ethical Issues Affecting Information Systems Use of information systems by employees and vendors: –Personal Use –Privacy Organizational use of information: –Employment records –Employee monitoring

Disaster Recovery & Backup Natural Disasters Power Failures Equipment Malfunctions Software Glitches Human Error Terrorist Attacks The most basic precaution – Backup. 90% of firms that sustained a loss of critical data went out of business within two years.

Information Systems Trends The Distributed Workforce –Employees who work in virtual offices Application Service Providers –A firm that provides computers and application support On Demand, Cloud, and Grid Computing –Renting software time
