7 Layers Explained in Computer Network

OSI Model

1. Application Layer  The master of communication! It deals with applications that require network communication and uses protocols like HTTP, FTP, SMTP, etc. to transmit data.

2. Presentation Layer  Transforms data into the right format for transmission. The layer compresses data, encrypts data, & translates data into ASCII codes or UNICODE for proper network communication.

3. Session Layer  Manages network sessions and authorizations. It establishes, manages, and terminates connections while ensuring authorized user access to particular files.

4. Transport Layer  Ensures smooth data transmission by segmenting the data into smaller parts, controlling the flow of data, and correcting errors in case of data inconsistency.

5. Network Layer  It identifies the network where data is transmitted and uses packets with source and destination IP addresses to route data to the appropriate destination.

6. Data-Link Layer  This layer adds MAC addresses to packets, generates frames, and ensures that data is ready for transmission to the destination.

7. Physical Layer  Converts frames into appropriate signals for transmission, including electrical pulses or laser beams. It deals with encoding the stream of bits into signals, ensuring smooth transmission of data.
