Technical help – Available on Internet (user must be comfortable with UNIX system)

Windows word processor is better than Linux

Linux vs. WindowsLinux vs. Windows

Head to head competitionUsed side by side as serversBoth handled daily workload for several

small business operationsLinux with hardware disadvantage

supported a community of users 3 times size of NT’s

In The Commercial ArenaIn The Commercial Arena

System Administration – Most significant differenceLinux – tougher environmentLinux requires learning multi-user issues built into

Unix-file permissionsNT – easier environmentNT requires less effort to get a starter server up and

runningBut in NT you have to solve multi-user issues for

each and every subsystem

11-38

In The Commercial ArenaIn The Commercial Arena

NT – graphical interfaces, wizards and easy-to-grasp metaphors

But as server chores become more customized, NT cannot handle it

Linux – textual interface (with X-Window)But for complex jobs, Linux gives a powerful

set of tools

NT – easy for non-programmerLinux – programmer-based culture

ConclusionConclusion

“When is it best to use Linux and when should some other operating system be preferred?”

It all depends on the user
