Operating System: collection of
software that directs a computer's
operations, controlling and
scheduling the execution of other
programs, and managing storage,
input/output, and communication
resources.
 Kernel: central component of most
computer’s OS; it’s a bridge between
applications and the actual data processing
done at the hardware level
Terms You’ll Need to Know
Software Stack: Middleware: connects software components
a set of
or applications. Software consists of a set of
software
services that allows multiple processes
subsystems or
running on one or more machines to interact
components
needed to
Application Platform: hardware
deliver a fully architecture or software framework
functional
(including application frameworks), that
solution
allows software to run
