What is the responsibility of physical layer?

The physical layer is the lowest layer of the OSI Network Model. It is the part that physically transfers data from one location to another location. For instance, in your cell phone, it is the physical radio that encodes, transmits, and decodes your data packets. In a carrier pigeon network, it would be the carrier pigeons and their pigeon roosts.


What is the purpose of the OSI physical layer?

The functions of the physical layer of the OSI model include data encoding, and transmission of the unstructured raw bit stream. It also includes description of the optical, mechanical, and electrical interfaces to the physical medium.


What are the different layers you think would be necessary for communication to be mapped to a model?

To effectively map communication to a model, several key layers should be considered: Physical Layer: This involves the transmission medium and hardware used for communication, such as cables, satellites, or wireless signals. Data Link Layer: This layer manages direct node-to-node data transfer, ensuring reliable communication over the physical layer. Network Layer: It handles routing and forwarding of data packets across the network, determining the best path for communication. Application Layer: This encompasses the protocols and interfaces that allow end-users to communicate effectively, such as email, messaging apps, or web services. Each layer plays a vital role in facilitating and enhancing the overall communication process.


What mechanical layer sits on top of?

The mechanical layer that sits on top of the physical layer in the OSI model is the data link layer. This layer is responsible for node-to-node data transfer and error detection and correction, ensuring reliable communication between devices on the same network. It encapsulates the raw bitstream from the physical layer into frames, adding necessary addressing and control information.


Which layer is immediately below the data link layer?

Physical layer


Explain in detail the layers of OS?

In computing, the Open Systems Interconnection model partitions a communication system into seven layers. They are the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer.


What is the use of RS 232 in OSI physical layer?

RS-232 is a standard for serial communication that defines the electrical and physical characteristics of the interface between data terminal equipment (DTE) and data communication equipment (DCE) at the OSI physical layer. It specifies parameters such as voltage levels, signal timing, and pin configurations, enabling reliable transmission of binary data over short distances. While it primarily facilitates point-to-point connections, RS-232 is essential for enabling communication across devices like computers, modems, and printers in legacy systems. Its role in the physical layer ensures that data is correctly formatted for transmission and reception.


Which layer is the network support layer?

Physical, Data link and Network layers make the Network Support layers.
