An O/S manages access to the resources of a computer.
O/S host applications, shielding them from the hardware.
Other popular operating systems:Windows XP, Windows Vista, MAC OS X
Unix looks more like DOS than Windows

Why Learn Unix/Linux?
Unix/Linux commonly used on computer “servers”:Web serversDatabase serversSupercomputers/Clusters
Over 50% of servers in corporations run Unix or Linux
A little Unix experience goes a long way, on the job, and looking for a job

Why Learn Unix/Linux?
At UM/MCSR:- to run Computational CHEM and STAT
apps- more disk space than on your PC’s- run one calculation for several days- for calculations too big for your PC or MAC
Student programming assignments may be completed on MCSR/UM systems
