FAQs on 7 LAYERS OF OSI -2 in very Detailed Manner - Specialist / IT Officer (BANK PO ;SBI ; LIC) Video Lecture - Computer Awareness for Competitive Exams (Hindi) - Banking Exams
| 1. What are the 7 layers of the OSI model? |  |
Ans. The 7 layers of the OSI (Open Systems Interconnection) model are:
1. Physical Layer: Deals with the physical transmission of data over the network.
2. Data Link Layer: Ensures error-free transmission of data frames between nodes.
3. Network Layer: Handles routing and logical addressing to enable data transfer between different networks.
4. Transport Layer: Provides reliable end-to-end communication and segmentation of data.
5. Session Layer: Establishes, manages, and terminates sessions between applications.
6. Presentation Layer: Handles data formatting, encryption, and compression for proper interpretation by the receiving application.
7. Application Layer: Provides network services to end-user applications.
| 2. What is the role of the Physical Layer in the OSI model? | |
Ans. The Physical Layer of the OSI model is responsible for the physical transmission of data over the network. It defines the electrical, mechanical, and procedural aspects of the physical medium, such as cables, connectors, and physical interfaces. The main functions of the Physical Layer include encoding, modulation, and transmission of bits, as well as the synchronization of data transmission between devices. It also deals with the physical characteristics of the network, such as data transmission rates, voltage levels, and physical topologies.
| 3. How does the Transport Layer ensure reliable communication? | |
Ans. The Transport Layer in the OSI model ensures reliable communication by providing end-to-end error recovery and flow control mechanisms. It breaks down the data received from the upper layers into smaller segments and assigns sequence numbers to each segment. These sequence numbers allow the receiver to rearrange the segments in the correct order. The Transport Layer also implements acknowledgment and retransmission mechanisms to ensure that all segments are successfully delivered. Additionally, it manages the flow of data to prevent congestion and overload on the network.
| 4. What is the purpose of the Session Layer in the OSI model? | |
Ans. The Session Layer in the OSI model is responsible for establishing, managing, and terminating sessions between applications. It allows different applications on different devices to establish a connection and exchange data. The Session Layer handles functions such as session establishment, synchronization, and checkpointing. It also manages session recovery in case of failures or interruptions. The Session Layer ensures that the data exchange between applications is organized and coordinated, providing a seamless and reliable communication experience.
| 5. How does the Presentation Layer handle data formatting? | |
Ans. The Presentation Layer in the OSI model handles data formatting to ensure proper interpretation by the receiving application. It translates the data from the application layer into a standard format that can be understood by different systems. This includes tasks such as data compression, encryption, and data conversion between different character sets or data formats. The Presentation Layer also handles data syntax and semantics, ensuring that the data is correctly structured and meaningful to the receiving application.
