Explanation
The two fundamental types of signals are Analog (continuous) and Digital (discrete).
Q.10 What does the acronym DCN stand for in networking?
Data communication Net
Data common Network
Data communication Networking
None
Explanation
DCN stands for Data Communication Networking, which refers to the infrastructure for data exchange.
Q.11 In a data communications system, the information to be communicated is called the?
Transmission
Medium
Message
None
Explanation
The ‘Message’ is the specific data, text, or information that is being sent from a sender to a receiver.
Q.12 What is the meaning of 'Transmission Mode'?
Transferring data between zero devices
Transferring data between one device
Mechanism of transferring data between two connected devices
None
Explanation
Transmission mode refers to the direction of signal flow between two linked devices.
Q.13 Which of the following was the world's first operational packet-switching network?
CNNET
ARPANET
ASAPNET
None
Explanation
ARPANET (Advanced Research Projects Agency Network) was the precursor to the modern Internet.
Q.14 A Computer Network can be defined as a?
Collection of hardware and computers
Interconnected by communication channels
System for sharing resources and information
All of the Above
Explanation
A network is a set of devices connected by communication links to share data and hardware resources.
Q.15 How many distinct types of Transmission Modes are there in data communication?
1
2
3
None
Explanation
The three types of transmission modes are Simplex, Half Duplex, and Full Duplex.
Q.16 Watching TV News is an example of which transmission mode?
Simplex
Half Duplex
Full Duplex
None
Explanation
Broadcasting TV news is Simplex because information flows only in one direction from the source to the viewer.
Q.17 Listening to the Radio is an example of which transmission mode?
Simplex
Half Duplex
Full Duplex
None
Explanation
Radio is a Simplex mode because the transmission is unidirectional; the listener cannot send data back through the same channel.
Q.18 Using a walkie-talkie is an example of which transmission mode?
Simplex
Half Duplex
Full Duplex
None
Explanation
Walkie-talkies use Half Duplex mode where both parties can communicate, but only one can transmit at a time.
Q.19 Modern Mobile phone conversation is an example of which transmission mode?
Simplex
Half Duplex
Full Duplex
None
Explanation
Mobile phones use Full Duplex mode, allowing both parties to send and receive data (speak and listen) simultaneously.
Q.20 Which of the following transmission modes is strictly unidirectional?
Simplex
Half Duplex
Full Duplex
None
Explanation
Simplex mode is unidirectional, meaning data can only ever flow from the sender to the receiver.
