The central object is

HostSystem

. Each property of

is a data object that encapsulates some information about the host. For example, the

capability

property is a

HostCapability

object, the

runtime

property is a

HostSystem

methods, but through methods in managed objects related to

. For example, you manage the host time using the

HostDateTimeSystem

and you manage kernel modules using

HostKernelModuleSystem

.
