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

Complete Question:
A system has defined specifications that describe how signals are sent over connections. Which layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model provides this function?
Group of answer choices.
A. Transport
B. Network
C. Data link
D. Physical
Answer:
A. Transport
Explanation:
Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard communication protocol used for interconnecting network devices such as routers, switches, host computers and access points over the internet.
A system has defined specifications that describe how signals are sent over connections. The layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model that provides these functions is the transport layer.
The transport layer comprises of two (2) standard protocols and these are TCP and UDP.
TCP is an acronym for Transmission Control Protocol and it is one of the essential and important protocol of the internet protocol network. This simply means that, it is an essential part of the TCP/IP network. The TCP has a wide range of applications in the following areas, file transfers, world wide web, remote administration, e-mail, etc.
The TCP connection are mainly established in the network using the three-way handshake.
UDP is an acronym for user datagram protocol and it enables the transfer or exchange of data between network devices.
