  - human bodies
  - nature
  - places
  - shops
  - made up of different organs that work together to complete a function
  - methods of doing something, a way of carrying out a task or operation
  - parts of the real world
  - patterns of relationships that are organized
  - stochastic in nature
  - substances
  - the means for attaining strategic goals and objectives
* are used for doings
  - organizations
  - specific tasks
  - when a bunch of parts are working together towards one purpose
* based on computing technology are powerful change agents in everyday society.
* can adapt either through learning or through evolution
  - also measure the vein patterns of person's hand and wrist
* can be real things , like a car 's engine
  - things, like a car's engine
  - consist of organisms, machines, fundamental particles, ideas, and numbers
  - have multiple functions including vision, memory, cell division, muscle contraction
* change involves continuous change over several years
  - over time
* clock The oscillator that controls the timing of signals on a circuit board.
* complex integration of various hardware components in a software environment.
* comprise a set of objects and their dependencies
  - collections of components , embracing both software and circuitry
* consists of collections of interacting particles
  - lymph capillaries, lymph veins and lymph nodes
* cure at room temperature, exposure to heat and upon exposure to UV light.
* emerge, change, and end within historical contexts.
* evolve by using ever-increasing increments of information.
* exercise the mind, but faith illumines and guides it.
* exist that mimic human thought, understand speech, and beat the best chess masters.
* generally involve cycles which operate as the system evolves.
* go from a state of low entropy, to a state of high entropy, as unusable energy increases.
* grow through the dynamic process of change.
* have a core and a periphery
  - way of balancing themselves out, particularly climate systems, which are way complex
  - inputs, processes, outputs and outcomes
  - parts that work together to perform a function
* impacted of key importance to humankind are crops and rivers.
* includes hierarchies.
* increase output with less input, pursuing growth, in co-evolution with nature.
* involve people, hardware, software, communication and processes.
* is an adaptation to conserve water
  - international trade fair for information technology, telecommunications and new media
  - instrumentation
* is the most widely used for classifying the world's climates
  - name of a class
  - orderly arrangement of parts and elements into a complete whole
  - used to inject cells, move omentum blood cell and transplant cardiomyocytes
* modeling powerful tool in the development of comprehensive solutions to problems.
* often exhibit both change and constancy
  - seem to have a life of their own and resist change
* refers to a combination of components working together
  - the reproduced relations between people organised as regular social practices
* set of interconnecting components operate together to achieve a specific purpose.
* studies the nervous system and part of the reproductive and musculo-skeletal systems.
* thinking also helps with teams and team building, because teams act as a system
  - and fractal geometry replace traditional analytical tools and methods
  - basis for clear thought and communication, a way of seeing more and further
  - discipline for seeing wholes
  - emphasizes efficient group problem-solving
  - encourages the creation of a learning organization
  - focuses counseling on the relationships among system parts
* thinking is an approach which views the world in terms of systems
  - important factor in solving global problems
* thinking is the art of finding the leverage, i.e. where actions leads to enduring changes
  - integration of the other disciplines with one another
  - process of understanding how things influence one another within a whole
  - key concept in most approaches to organizational learning
  - recognizes that every parts are interconnected
  - way of seeing the woods rather than a few close-by and obvious trees
* undergo stress in various ways.
* work together in an organism
  - to make up a large whole such as the Human body
+ Access control: Security
  * Most biometric systems do not keep an image of the fingerprint but a template. A template is basically a number that is calculated based on various characteristics of the fingerprint. This is done so that persons may not sneak unauthorised images of fingerprints into the database. Most systems allow for dry, greasy, chaffed and minor cuts on the fingers. The other biometric systems are based on retina of the eye, palm, photograph or voice pattern recognition. The palm-based systems take the image of the palm from various angles and compare them.
+ Answering machine: Machines
  * Today, most systems use computer memory to store the messages and the prerecorded text. Many systems allow to listen to the left messages by simply calling the answering machine.
+ IEEE 1394, Technical description, Security issues: Computer hardware :: Electrical connectors
  * This feature can also be useful, for example to debug a machine where the operating system has crashed. Some systems can use it to provide a remote console. On FreeBSD, the dcons driver provides both, using gdb as debugger.
  * These things can be real or imaginary. Systems can be real things, like a car's engine. But systems can also be things made by persons to organize ideas, groups, people, and anything else. A subsystem is a little system within a big system.
