OCR COMPUTING

1)A system is a collection of parts work together for a common purpose. For a system to be useful it must produce an output. It needs to process inputs and produce outputs. Systems usually interact with other systems, the systems might be made from many sub-systems.

2)A proprietary standard is a privately owned standard widely followed in an industry due to the owner's market power. An open standard are standards available to the general public and are developed and maintained by a collaborative or consensus driven process.

3)De Facto standards have helped developed easy to use systems because many systems use the same standards, for example HTML and QWERTY.
 
4) An embedded system is a combination of computer hardware and software that is specifically designed for a particular function

5)The kernel is the central part of an operating system the controls the hardware.

Algorithms

                               Flowcharts

A flowchart is a form of diagram that represents an algorithm, process or workflow. A flowchart is represented using different boxes to show different functions, and lines to show their order. Flowcharts can be used to display simple processes and programs, giving a visual aspect, to make it easy to follow and understand. The flow chart was introduced by Frank Gilbreth, to the members of ASME in 1921.
