Question
II. For each statement below, decide whether it is true or false (2 point each, 20 total)
(T) (F) 1. Video networks in business are used primarily to deliver programs.
(T) (F) 2. Intranets use the same communication protocols and applications as the Internet.
(T) (F) 3. When using message switching instead of packet switching, a dedicated path must be established between the parties for all messages that are sent.
(T) (F) 4. Packet switching is like message switching except that the unit of data sent at one time is limited in size, thus requiring larger messages to be broken into pieces.
(T) (F) 5. The service-oriented architecture (SOA) is a form of client/server computing.
(T) (F) 6. Middleware is used to overcome lack of standardization.
(T) (F) 7. Upon receipt, the SMTP receiver must decide whether to place the message in the appropriate user mailbox or local outgoing mail queue.
(T) (F) 8. SMTP does not place any requirements on the contents or message bodies of mail it processes.
(T) (F) 9. In general, the performance of a LAN declines with increased lengths of connections and/or the number of devices using it.
(T) (F) 10. Having multiple paths from one station to another through a network contributes to reliability.
Explanation / Answer
1.FALSE : this is no only for deliver programs to communicate with clients and employee management will use video networks
2.TRUE: Both internet and intranet re using email,file transfer(FTP) and same web protocols uch as HTTP etc
3.FALSE : packets are trasmitted through shared medium
4.TRUE: packet switching is dividing of messages into packets before they are sent, tranmitting packets individually, and then reassemble them into original message at the time of arrival at destination
5.FALSE: The Client -Server architecture follows fat client that processing bulk of data where data-related logic and database server lying on the server.In the case of SOA options exist regarding to where the application logic will.
6.TRUE:middleware used to fill in the platform where stabdards are no there
7.TRUE:SMTP is a protocol that receives and and sends mails by nalyizing appropriate user.
8.FALSE: some times for accuracy SMTP will compress meassage to 7bits or add some other data to message
9.TRUE: As number of connections increases in LAN will decreases its speed as bandwidth utilization is more
10.TRUE: by having multiple paths the networks speed will inceases in other words we can say reliability increases
