• Probably the most familiar platform is Microsoft

• Android is an operating system based on the Linux
kernel
Hardware Architecture
• A set of disciplines that describes a computer
system by specifying its parts and their relations
provides physical environment.
• Types
– Commodity computing platforms
– Video game consoles
– RISC
– Midrange computers
– Mainframe computers
– Supercomputer
Software Frameworks
• An abstraction in which software providing

changed by additional user-written code.
• It is an universal, reusable software platform
to develop software applications, products
and solutions.

Examples
• The Java platform is a virtual machine platform
which runs on many operating systems and
hardware types.
Operating Systems
• A collection of software that manages
computer hardware resources and provides
common services for computer programs.
• The operating system is an essential
component of the system software in a
computer system.
• Application programs usually require an
operating system to function.
