Which flow types apply to each set of flows described below?

a. Users on the internet accessing the same Web server

b. Forty workstations processing batch jobs overnight, managed by a central mainframe.

c. Email use across the internet

d. A transaction-processing application, authorizing credit card transactions between a company’s retail stores and its headquarters

Answer 1

(a) This displays the flow type of a Client-Server - in this one program(the client) requests a service or resource from another program(the server)

(b) This displays Distributed computing - in this the components of a software system are shared among multiple computers. Forty workstations processing the data are the data sources these data sources would flow the data to the data source or the mainframe

(c) Email use across the Internet flow from the user to the server.

A combination of client-server and peer to peer network.

In a peer to peer network, a number of workstations (or clients) are connected together for sharing devices, information or data.

(d) A transaction-processing application flows information both ways since an authorization and authentication is to be checked in both directions when money is involved
