Answer:

The lossy compression method is also known as irreversible compression and is beneficial if the quality of the data is not your priority. It slightly degrades the quality of the file or data but is convenient when one wants to send or store the data. This type of data compression is used for organic data like audio signals and images. The algorithm use in Lossy compression include: Transform coding, DCT, DWT, fractal compression, RSSMS.

The Lossless compression method is also known as reversible compression and is capable of reconstituting the original form of the data. The quality of the data is not compromised. This technique allows a file to restore its original form. Lossless compression can be applied to any file format can improve the performance of the compression ratio. The algorithm use in Lossless compression include: RLW, LZW, Arithmetic encoding, Huffman encoding, Shannon Fano coding.

Advantage of Lossy compression: Lossy compression can achieve a high level of data compression when compared to lossless compression.

Advantage of Lossless compression: Lossless compression doesn’t degrade the quality of data during compression

Disadvantage of Lossy compression: Lossy compression degrades the quality of the data during compression

Disadvantage of Lossless compression: Lossless compression has less data holding capacity when compared to lossy method

Example of type of data for Lossless compression: Text

Example of type of data for Lossy compression: Audio

Answer:

Lossless retains the file size while lossy algorithm discards excess files size or parts.

Explanation:

Compression algorithms are algorithms used to minimise the file size of a large file format. It is handy for maximising available disk space and reduce upload and download time of these files. Lossless and lossy are two types of compression algorithms.

Lossless algorithm is used to compress a file, but yet retains the structure of the original file or data. It is used where an identical file from the original is favourable and is used in archives.

Lossy is the opposite of lossless because it discards excess parts of a file. It is used in compressing audio files like MP3.

Answer:

B. GRID COMPUTING , ON - DEMAND COMPUTING AND REAL TIME COMPUTING

Explanation:

Grid computing, on-demand computing and real time computing are currently the most impactful information technology processes. The Grid computing from example entails distributed computing whereby computing resources are distributed across different systems for a computing task. This is seen in server systems where a super virtual computer composed of a network of computers are connected to share resources and perform large tasks. This form of computing has majorly affected and improved complex computing tasks today.

On demand and real time computing are also other notable trends in IT with real time computing bringing the power of live and direct coverage of information to our screens and on demand making it possible for the average user to access computing resources as needed such as in the services of cloud computing providers

Why does the definition of fair use remain ambiguous?
bogdanovich [222]
Millions of dollars in legal fees have been spent attempting to define what qualifies as a fair use.

There are no hard-and-fast rules, only general guidelines and varied court decisions, because the judges and lawmakers who created the fair use exception did not want to limit its definition.

Like free speech, they wanted it to have an expansive meaning that could be open to interpretation.
