Choosing Hardware
• Thick Clientsvs.
• Thin Clients
![Page 7: The Perfect Computer Lab Low-cost and low-maintenance: An impossible dream? In search of](https://reader035.vdocuments.net/reader035/viewer/2022062716/56649de55503460f94add810/html5/thumbnails/7.jpg)
Thick Client
• Fast processor• Lots of storage space• State of the Art• Good for multimedia• Nice, but expensive!!
• Lots of workstation maintenance often required.
![Page 8: The Perfect Computer Lab Low-cost and low-maintenance: An impossible dream? In search of](https://reader035.vdocuments.net/reader035/viewer/2022062716/56649de55503460f94add810/html5/thumbnails/8.jpg)
Thin client
• Usually slower processor• Often has no hard drive
• Easy management since there is little to go wrong
• Good for Internet/word processing
• Speed limited by network and server• Cheap!

The fit client
• Small hard drive (< 5 gigs)• Most commonly used
applications are installed locally• No data is stored locally• Very little management required• Utilize the workstation processor
and resources

Buy cheap, but not too cheap
• Buy good mice (Logitech/Optical)
• Buy good headphones (I like the Califone ones)
• Buy good keyboards (or replace them regularly)
• Keep your monitors in good order
• Aim for identical hardware

Operating Systems
• Microsoft vs. Linux?• Either way: older
hardware means use lighter software
• Open vs. School Licensing
• Consider downgrading your license

Secrets of the “fit” client

Office Applications
• Fit to hardware• Consider Office 97
• Consider OpenOffice
• Make a uniform installation(same hardware / same software)
![Page 22: The Perfect Computer Lab Low-cost and low-maintenance: An impossible dream? In search of](https://reader035.vdocuments.net/reader035/viewer/2022062716/56649de55503460f94add810/html5/thumbnails/22.jpg)
• Look for managed, network software even if it costs more– Mavis Beacon Teaches Typing– ClassWorks– Accelerated Reader
• Remember no data is stored on a fit client locally — avoid software that cannot store data on network drive
Courseware

• Consider classic educational products like: LOGO that are freely available and have an active community for support.
Courseware
• Consider inexpensive older product versions available online or shareware to complement your courseware.

Summing it upThere may not be a “perfect” lab. But with the right expertise and planning it is possible to set-up a low-cost, low-maintenance computer lab. Using “fit” clients rather than high end systems saves both money and time and reduces the total cost of ownership.
