Netscape, which once controlled more than 80 percent of the market share in web browsers, lost its dominant position when customers migrated to internet explorer, microsoft's web browser. internet explorer was easy to install and had no significant differences in terms of usability. this example serves to illustrate that:
a. fast-following smaller firms are always ready with newer and possibly superior products.
b. customers of technology companies are becoming increasingly savvy and more demanding.
c. the open source nature of technology ensures that no firm can expect to monopolize a market.
d. firms need to employ increasingly stringent intellectual property norms to guard against infringements from smaller, competitive rivals.
e. firms with low switching costs can sometimes be rapidly overtaken by strong rivals with additional competitive advantages.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !

First one good luck
