Note: Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Q. 1. a. Discuss computer networks categorically.
Answer:A computer network or data network is a telecommunications network which allows
computersto exchange data. In computer networks, networked computing devices exchange data
with each other along network links (data connections). The connections between nodes are
established using either cable media or wireless media. The best-known computer network is the
Internet.
Networkcomputerdevicesthatoriginate,route andterminatethe dataare callednetworknodes.[1]
Nodes can include hosts such as personal computers, phones, servers as well as networking
hardware. Two such devices can be said to be
b. Define Network protocols. What are the various types of computer network?
Answer:Network congestion occurs when a link or node is carrying so much data that its quality of
service deteriorates. Typical effects include queueing delay, packet loss or the blocking of new
connections. A consequence of these latter two is that incremental increases in offered load lead
either only to small increase in network throughput, or to an actual reduction in network
throughput.

2. Q. 2. Explain the following terms:
a. Video Compression
Answer:Video compression uses modern coding techniques to reduce redundancy in video data.
Most video compression algorithms and codecs combine spatial image compression and temporal
motion compensation. Video compression is a practical implementation of source coding in
informationtheory.Inpractice,mostvideocodecsalsouse audiocompressiontechniquesinparallel
to compress the separate, but combined data streams as one package.
b. Audio Compression
Answer:Audio data compression, as distinguished from dynamic range compression, has the
potential to reduce the transmission bandwidth and storage requirements of audio data. Audio
compression algorithms are implemented in software as audio codecs. Lossy audio compression
algorithms provide higher compression at the cost of fidelity and are used in numerous audio
applications. These algorithms almost all rely on psychoacoustics to eliminate less audible or
meaningful sounds, thereby reducing the
Q. 3. Discuss the features of the Bluetooth technology and how they all make it work.
Answer:Bluetoothisawirelesstechnologystandardforexchanging data over short distances (using
short-wavelength UHF radio waves in the ISMband from 2.4 to 2.485 GHz]) from fixed and mobile
devices,andbuildingpersonal areanetworks(PANs).InventedbytelecomvendorEricssonin1994, it
was originally conceived as a wireless alternative to RS-232 data cables. It can connect several
devices,overcomingproblems of synchronization. Bluetooth is managed by the Bluetooth Special
Interest Group (SIG), which has more
Q. 4. Explain the network configuration of Dense wavelength division multiplexing (DWDM) and
its pros and cons.
Answer:Dense wavelengthdivisionmultiplexing(DWDM) iswavelengthdivisionmultiplexing(WDM)
with typical channel spacing of 100 GHz for 40 channels and 50 GHz for 80 channels. Each channel
containsa TDM (time divisionmultiplex) signal.Andeach of up to 80 channels can carry 2.5 Gbps for
a total of 200 billion bits per second by the optical fiber. These signals use the 3rd transmission
window, called the C-Band, meaning the light beam

3. Q. 5. Shed light on User-to-network and Network-to-network connectivity and the technologies
used.
Answer:A wirelessnetworkisanytype of computernetworkthatuseswirelessdata connections for
connectingnetworknodes. Wirelessnetworkingisamethodby which homes, telecommunications
networksandenterprise (business) installationsavoidthe costlyprocessof introducing cables into a
building, or as a connection between various equipment locations. Wireless telecommunications
networks are generally implemented and
Q. 6. What are the benefits and drawbacks of Cloud computing?
Answer:There is nodoubtthat businessescanreap huge benefits from cloud computing. However,
withthe manyadvantages,come some drawbacksas well. Take time to understand the advantages
and disadvantages of cloud computing, so that you can get the most out of your business
technology, whichever provider you choose.
