preparation machine where you can get different flavours.
A system for distributing electronic mail over network is needed. Each
user of the system should be able to send mail from any computer. All the received mails are stored at a central server. The user can receive mail at any computer. One or two machines with larger data spaces also allows saving messages in files. There should be provisions for forwarding mails and sending mail to several users at once using address list. Draw component and deployment diagram.
Q4) Attempt any four of the following : [4 × 4 = 16]
a) Write short note on object oriented testing.
b) How a use case model helps in analysis phase from inception to
elaboration?
