OIT maintains 12 Computer Labs with a total of 453 computers: 7 instructional labs (270 computers) and 5 “drop-in” labs (183 computers). (Complete information about these facilities can be found at http://www.oit.uci.edu/labs/.) The 50 PCs in the Instructional Computer Labs in MSTB 210 will be replaced to meet the demands of current classroom use. The units replaced will be deployed into drop-in labs to take the place of even older systems. Additionally, the heavily used Student Center B109 and C138 drop-in labs will get a previously deferred refresh of 20 iMacs.
