What is a good working definition of what a System is and perhaps what it is not?

A set of interdependent parts/activities that interact together to produce a work; there is often a underlying mechanics that determine the type of system. A group of parts, or a set of activities that do not produce work is not a system.

For the 4 system definitions you were to look up please give in your own words what they mean and give an example of them for each case?

Modularity: Refer to a flexible nature of a system's components in being rearranged, combine, upgraded.

Decomposability: Refer to a minimum viable state of a component. In a system, this refer to the most basic functional component/part.

Emergence: Refer to a bottom-up development of pattern resulted from interaction of the system's component; these interaction can be rather simple.

Chaos: Refer to a system with whose outcome/work is unpredictable upon stimulus input.

Give us your definition of what Tessllation means and give an example you encountered, not mentioned in the reading?

Tessellation is a geometric shape that can be repeated over and over--without any overlaps--to form a pattern. The shape can be repeated with symmetrically, asymmetrically, translationally, rotationally or by glide reflection. An example of Tessellation would be my house's Terracotta tile; other example would be window's ventilation hole's Terracotta pattern.

What is The difference between ideas of Modularity and Tessellation? What are the properties that are in opposition with each other?

Modularity refers to the ability to rearrange, combine and upgrade each component of a system. Tessellation is built upon repeating a fixed geometric shape without overlapping them. In short, the opposing property of Tessellation against Modularity is its fixed, unchangeable nature.

What is the difference between designing something that has Complexity (aperiodic) vs being Uniform (periodic)?

Periodic design--or uniform design--focuses on the likeness of each basic shape. Complex design--or aperiodic design--emphasizes on change, and often refers to a complete change in degree from start to finish.
