7. Other Considerations for PCs Warranty –Usually 1 year for parts and labor –Repair on site vs. drop off –May need to keep boxes Internet Access –Have to select an Internet Service Provider (ISP) –FiOS, DSL, cable are all options –May depend on what's available in your location 7 Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Information and Computer Science Basic Computing Concepts Including History Lecture c

8. Other Considerations for PCs (continued) Security Software –Windows 7 has Defender –Add more from other vendors (Norton, McAfee) –Need anti-viral, anti-spyware, anti-adware Backing up –Software makes it easier to backup and restore –Can back up to external hard drive or DVD –Online services 8 Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Information and Computer Science Basic Computing Concepts Including History Lecture c

9. Computer Systems for Healthcare Applications 9 Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Information and Computer Science Basic Computing Concepts Including History Lecture c Vary depending on software requirements Typical for EMR –Server(s) hosts application, database –Local machine runs application (client) Need –Server(s) –Client PCs –Network connection

10. Selecting a Server 10 Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Information and Computer Science Basic Computing Concepts Including History Lecture c Depends on application requirements and number of users Usually contains –High end processor/multiple processors –Large amount of RAM –Large amount of storage (RAID) –Connection to a fast network (multiple connections) May need –Database –Web server

11. Client PCs 11 Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Information and Computer Science Basic Computing Concepts Including History Lecture c Desktops for fixed computer locations –Users who work at desks –Can be in exam room –Doesn't need wireless Laptops/netbooks for mobile computing –Users can have own computer –Take it to any clinical setting –Requires wireless –Limited battery life

12. Other Needs 12 Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Information and Computer Science Basic Computing Concepts Including History Lecture c Scanners –Small footprint –ID card scanner Back up systems –Tape –Hard Drive –Online –May need offsite backup storage Internet Access Security –Network firewall –Security software for servers and clients
