Q4. Which of the following statements is true for three-tier architecture?
(a) It is easy to setup
(b) It has a simply structure
(c) It provides high network traffic
(d) It is more secure
(e) None of these
Show Answer
S4. Ans.(d)
Sol. In the three-tier architecture, there is an additional server, called the application server, between the client and database servers. The application server reduces the work of the database server, thereby making application processing efficient. It is more secure because the client cannot access the database directly. However, it is more complex to build.

(a) Volatile
(b) Non-volatile
(c) ROM
(d) Pen Drive
(e) Google Drive
Show Answer
S5. Ans.(a)
Sol. Volatile memory is a type of memory that clears everything when the power of a computer gets switched off, whereas nonvolatile memory retains the data even when the power gets switched off. Moreover, ROM and flash memory also retain the data in case the power gets switched off.

Q10. Which communication mode allows both the sender and the receiver to transmit data at the same time over a single communication channel?
(a) Simplex mode
(b) Half-duplex mode
(c) Full-duplex mode
(d) Semi-duplex mode
(e) None of these
Show Answer
S10. Ans.(c)
Sol. In the simplex mode, communication is always unidirectional, for example television. In the half-duplex mode, communication is bidirectional but one at a time, which means only one of the parties can send data at a time. Walkie-talkie is an example of half duplex communication. In the full-duplex mode, communication is bidirectional, which means both the parties can transmit data simultaneously. Telephone is an example of full-duplex communication. The semi-duplex mode is not and type of communication mode.
