DATA Communication QUIZ 1
Data Communications - ANS-refers to the transmission of this digital data between two or more
computers and a computer network or data network is a telecommunications network that allows
computers to exchange data.
Network - ANS-A set of devices often mentioned as nodes connected by media link is called a
Node - ANS-can be a device which is capable of sending or receiving data generated by other
nodes on the network like a computer, printer etc.
Communication Channels - ANS-These links connecting the devices are called
Computer Network - ANS-is a telecommunication channel through which we can share our data
Data Network - ANS-Computer Network is also called?
Internet - ANS-The best example of computer network is
Distribution System - ANS-. Computer network does not mean a system with control unit and
other systems as its slave. It is called a
Communication - ANS-This means exchange of informations
Protocols - ANS-Set of rules which govern data communication
Packet - ANS-Smallest bit of data
Deliver
Accuracy
Timeliness
Jitter - ANS-Four Fundamentals in Data Communication
Video Calls - ANS-Where we can experience "jitter" ?
Transit Time - ANS-It is the time taken to travel a message from one device to another.
Response Time - ANS-It is defined as the time elapsed between enquiry and response.
Reliability - ANS-It decides the frequency at which network failure take place. More the failures
are, less is the network's
, Security - ANS-It refers to the protection of data from the unauthorised user or access. While
travelling through network, data passes many layers of network, and data can be traced if
attempted.
Interpersonal Communication - ANS-We can communicate with each other efficiently and easily
example emails, chat rooms, video conferencing etc.
Communication Model - ANS-The diagram used to exchange data between two parties. For
example communication between a computer, server and telephone (through modem).
Source - ANS-Data to be transmitted is generated by this device, example: telephones,
personal computers etc.
Transmitter - ANS-The data generated by the source system are not directly transmitted in the
form they are generated. The __________________ transforms and encodes the information in
such a form to produce electromagnetic waves or signals.
Transmission System - ANS-can be a single transmission line or a complex network connecting
source and destination.
Receiver - ANS-accepts the signal from the transmission system and converts it to a form which
is easily managed by the destination device.
Destination - ANS-receives the incoming data from the receiver.
Data - ANS-The exchange of data between two devices through a transmission medium is
__________ Communication.
Wire Cable - ANS-The transmission medium used is ________ ____________.
Delivery - ANS-_____________ should be done to the correct destination. (Fundamentals in
Data Communications)
Timeliness - ANS-Delivery should be on time. (Fundamentals in Data Communications)
Accuracy - ANS-Data delivered should be accurate. (Fundamentals in Data Communications)
Message - ANS-It is the information to be delivered.
Sender - ANS-is the person who is sending the message.
Receiver - ANS-is the person to him the message is to be delivered.
Medium - ANS-It is the medium through which message is to be sent for example modem.
