server, DHCP server, DNS server, …and run smoothly
You do NOT need to reboot machine after installing new
softwares or services

Scalability
The release of the 2.4 kernel can handle large business
workloads that once could only be addressed by closed,
proprietary platforms and solutions
Security
The open source model allows for auditing policy
When problems are found, fixes are developed and tested
by the group of worldwide programmers
Viruses are almost non-existent on Linux
ROI (Return On Investment)
The open source licensing model allows for no per unit fees
or licensing charges.
This will significantly reduce IT infrastructure expense
TCO (Total Cost of Ownership)
Each Linux administrator can maintain a large number of
servers and clients. This reduces the total cost of ownership of
Linux versus Windows, Netware and other PC platforms
