WHAT'S A VIRTUAL SERVER?

A virtual server is a basically a
partitioned drive on a main server.
Multiple virtual servers can be created
from a single server which would have
capabilities of acting as a separate
serve altogether i.e. a virtual server can
run a full operating system as well as
be rebooted without aff ecting other
virtual servers. First, the physical server
is booted in a normal manner. Once
the boot process has been completed,
a program is executed which then
boots all virtual servers on a machine.
Virtualization can be of two kinds i.e.
software virtualization and hardware
virtualization. Software virtualization is
mainly used for web hosting services
wherein the same kernel is used. In
hardware virtualization, hardware
resources are partitioned accordingly.
Virtual private servers are mainly used
for security purposes. For instance, if
you require installing a software that
might contain bugs, it would be wise
to install and test on a virtual server
so that the main server is not eff ected
incase it contains any bugs
