Question

Translation encryption and compression are some of the duties of the presentation layer in the osi model which layer is responsible for these duties in the internet model?explain your answer

Answer 1

Answer:

The presentation layer is responsible for translation, encryption, and compression of data.

Explanation:

This is also called layer 6.

Presentation layer is also called the Translation layer.The data from the application layer is extracted here and manipulated as per the required format to transmit over the network.

The functions of the presentation layer are :

Translation : For example, ASCII to EBCDIC.

Encryption/ Decryption : Data encryption translates the data into another form or code. The encrypted data is known as the cipher text and the decrypted data is known as plain text. A key value is used for encrypting as well as decrypting data.

Compression: Reduces the number of bits that need to be transmitted on the network

Answer 2

Translation encryption and compression are some of the duties are:

Explanation:

• Translation, encryption, authentication, and data compression are all handled by the OSI model's sixth layer.

• In most cases, SSL is used to encrypt data, and no specific translation is required (content encoding is recognised by the browser directly and typically we just use utf-8 as it simply works).

• Compression isn't common, however it can be done as an HTTP protocol enhancement (Content-Encoding header).

• In a way, I suppose encoding and compression are part of the Application layer (and laying on top of HTTP)
