Question 1

Porter’s Five Forces

Answer 1

supplier power, buyer power, competitive rivalry, threat of substitution, threat of new entry

Question 2

digitization vs. digitalization vs. digital transformation

Answer 2

Digitization: a business shifts from manual and paper-based ways of processing data and information to computerized approaches.

Digitalization: an organization shifts from isolated islands of digital technologies to networked and integrated technology systems

Digital transformation: an organization uses technology to critically change the way it competes as well as its internal capabilities and internal digital assets. Digital transformation leverages digital technology to radically improve, restructure, or entirely create new value to their customers.

Question 21

Impacts of moore’s law

Answer 21

> faster processing of transactions
larger numbers could be processed
larger size of primary storage could be used by the CPU
multiple software applications could be run concurrently on a PC
improvement in performance/cost ratio for customers
relatively cheaper to build large computers
energy efficiency of CPUs is improved

Question 22

challenges of moore’s law:

Answer 22

> packing pathways tightly together creates problems associated with size, heat, power (chip starts to melt when processor gets smaller)
chips can’t get smaller forever (get too small > quantum tunneling)

Question 23
