Digital Representation
Digital is an abstraction of analog voltage
Voltage is a continuous, physical unit
Typically ranging from 0 to 5 volts on PCs
Digital logic abstracts it to 2 distinct levels  “1” or positive (typically 2.5 V or greater)  “0” or negative (typically less than 1 volt)
Eases design and manufacturing

This thesis examines how designs based on a conjunction between craft and digital techniques may offer new possibilities for an architect or designer in contemporary practice. How is it relevant that what initially appear to be two distinct approaches to designing and making can be introduced to each other and coalesce to form a constructive attitude of mutually borrowed logic? The thesis champions the crafting of innovative design and the incorporation of digitally derived procedures that allow for globally efficient dissemination and malleability.

Question 1. Reorder the following efficiencies from the smallest to the largest: a. 2n3 + n5 b. 2000 c. 4n+1 d. n4 e. (n-1)! f. nlog2(n) g. 2klogk(n) (k is a predefined constant) Solution: Efficiency: a measure of amount of time for an algorithm to execute (Time Efficiency) or a measure of amount of memory needed for an algorithm to execute (Space Efficiency). Non-decreasing order: 2000
