Digital Espresso
I have several computer questions. Can you help?
An analyst identifies a delay in billing as a symptom rather than a problem, but he recommends that the project move on to the next stage. What phase of the systems development life cycle comes next?
A) Systems analysis
B) None, since there are no system problems
C) Preliminary investigation
D) System design
(I think it's B..am I right?)
An Internet coffee vendor learns that you live in an affluent suburb and recently bought a high-priced espresso make online. The information probably came from
A) marketing databases
B) cyberstalkers
C) hackers
D) value-added resellers
(marketing databases???)
and last but not least....
Online purchases can be speeded up by storing a buye's payment, shipping, and billing information so it can be supplied electronically. That information is stored in a/an
A) smart card
B) digital wallet
C) online check
D) digital signature
(Smart card???)
Thanks SO much for your help!!!!!!
First one is none because after testing it is implemetation phase.
second is value added resellers, marketing dbase is only when a consumer purchases a product or sevice.
third is digital wallet, smart card is a physical device with microchip in for storing data,digital signature is for authenticating
