OSI MODEL - Presentation Layer
#Summary - In today's video we will discuss about Presentation Layer of OSI Model.
#Presentation Layer - Presentation Layer is the sixth layer of the OSI Model. At sending end, It receive data from application layer and passes to Session Layer. At receiver end, It receive data from Session Layer and passes data to the Application Layer.
*Responsibilities of Presentation Layer -
a) Translation - Presentation Layer Changes information from its sender dependent format into a common format that will be accepted by the receiving device.
b) Encryption - Encryption is a process in which the data is converted into a form that prevents unauthorized users from reading and decrypt its encrypt data at the receiver's end .
c) Compression - Compression is the process reduces the number of bits used to represent the information.
• Two types of Compression -
1. Lossless Compression - No lose of data
• Two types of Compression -
1. Lossless Compression - No lose of data
2. Lossy Compression - Some Lose of data..
