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.](https://image.slidesharecdn.com/mi0035-computernetworks-150827070348-lva1-app6892/85/Mi0035-computer-networks-1-320.jpg)
![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. 4. Explain the network configuration of Dense wavelength division multiplexing (DWDM) and
its pros and cons.
Answer:Dense wavelengthdivisionmultiplexing(DWDM) iswavelengthdivisionmultiplexing(WDM)

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](https://image.slidesharecdn.com/mi0035-computernetworks-150827070348-lva1-app6892/85/Mi0035-computer-networks-2-320.jpg)
