Dive deep into the OSI Model to understand its seven layers, their functions, and how it defines the networking framework to implement protocols in seven layers.
The other six layers are the physical layer, the data link layer, the network layer, the transport layer, the session layer, and the presentation layer. What are common cybersecurity threats to the application layer? Viruses, keylogger malware, and Trojan horses are common threats to the ...
The OSI model starts with the physical layer, which acts as the foundation for the other layers, all the way to the top application layer. The physical layer is the layer closest to the physical connection between devices. This layer covers a variety of devices and mediums, among them cabli...
Layer 1 is the first layer of the OSI Model, and therefore, the foundation upon which all higher-level functions are based. It translates the information that receives from the data-link layer (layer 2) into electromagnetic signals (binary data) to send them over the physical medium (wired ...
The Earth’s layers (strata) shown to scale. Credit: pubs.usgs.gov The thinner parts are the oceanic crust, which underlies the ocean basins at a depth of 5-10 km (~3-6 miles), while the thicker crust is the continental crust. Whereas the oceanic crust is composed of dense material ...

How Does the Physical Layer Interact with the Other Layers? Once the actual communication media and system have been designed, it’s also necessary to create chips that can encode and decode the signals sent over the physical media. These chips are generally referred to as PHY chips. These ch...
It is physical and tangible as well. However, it does not deal with the actual physical medium (like fiber, copper). Physical Layer devices are Hub, Repeater, Modem, Cables.This figure shows the position of the physical layer concerning the transmission medium and the data link layer.Physical...
The function of the Application Layers are Application-layer helps you to identify communication partners, determining resource availability, and synchronizing communication. It allows users to log on to a remote host This layer provides various e-mail services ...
Layers are conceptualized as sheets or strata that overlay or underlay each other, often used to describe physical materials, geological formations, or abstract concepts like software architecture. Each layer serves a distinct function or represents a different component within a larger system, emphasizin...
