Yes, SMTP (Simple Mail Transfer Protocol) relies on the underlying network infrastructure, which includes the physical data link layer, for transmission. While SMTP operates at the application layer of the OSI model, it requires the lower layers, including the physical layer, to facilitate the actual sending and receiving of data packets over a network. Without the physical data link layer, SMTP messages could not be transmitted between servers or clients.

What is network access layer?
The network access layer is the lowest layer of the TCP/IP model, responsible for facilitating the physical transmission of data over a network. It encompasses the protocols and technologies that enable devices to connect to a network, including Ethernet, Wi-Fi, and other physical media. This layer handles tasks such as framing, addressing, and error detection, ensuring that data packets are properly transmitted to their destination. By managing the interaction between the network and the physical hardware, the network access layer plays a crucial role in network communication.
Which layer is the network support layer?
Physical, Data link and Network layers make the Network Support layers.
Which layer of OSI Model is the network interface card of LAN related to?
The network interface card (NIC) of a Local Area Network (LAN) primarily operates at the Data Link Layer (Layer 2) of the OSI model. This layer is responsible for node-to-node data transfer and framing, enabling the NIC to manage how data packets are placed on and received from the physical medium. Additionally, the NIC also interacts with the Physical Layer (Layer 1), which deals with the physical connection and transmission of raw bits over the network medium.
What is transmission layer?
physical
Which layer arranges the transmission of a data frames bits when they are dispatched across the network?
The Data Link layer is responsible for arranging the transmission of data frames' bits when they are dispatched across the network. It ensures reliable transfer of data frames between directly connected nodes by managing error detection and correction, as well as framing and addressing. This layer operates above the Physical layer, which handles the actual transmission of raw bit streams over the physical medium.
Is the transmission medium a part of physical layer why or why not?
The Physical Layer defines the means of transmitting raw bits rather than logical data packets over a physical link connecting network nodes. The bit stream may be grouped into code words or symbols and converted to a physical signal that is transmitted over a hardware transmission medium. The Physical Layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to broadcast on, the modulation scheme to use and similar low-level parameters, are specified here. Within the semantics of the OSI network architecture, the Physical Layer translates logical communications requests from the Data Link Layer into hardware-specific operations to affect transmission or reception of electronic signals.
