CN1047 INTRODUCTION TO COMPUTER NETWORKING CHAPTER 3 OSI. layer 1 is the physical layer and, under the osi model, defines the physical and electrical characteristics of the network. the nic cards in your pc and the interfaces on your routers all run at this level since, eventually, they have to pass strings of ones and zeros down the wire. layer 2 layer 2 is known as the data link layer. it defines the access strategy for sharing the physical medium, figure 1 displays the iso 11898 standard architecture using the bottom two layers of the osi model, the data-link layer and the physical layer . the data-link layer is responsible for transferring messages from a node to the network without errors.).

OSI MODEL –PHYSICAL LAYER. Physical Layer Concern with transmission of raw bits over a communication channel. It deals with specifications of network connectors, type of transmission media and voltage level used for 0 bit and 1 bit. Types of Media Communications media has 2 classes : 1) Conducting media 2) Radiating media. Types of Media 1) Conducting media-Referred as bounded … The physical layer of the OSI model defines connector and interface specifications, as well as the medium (cable) requirements. Electrical, mechanical, functional, and procedural specifications are provided for sending

In the OSI model, information is passed from one layer to the next, starting at the applica- tion layer on the transmitting host and proceeding down the hierarchy to the physical layer, then passing over the communications channel to the destination host, where the informa- It is the topmost i.e. seventh layer of OSI Model. It enables the user to access the network. It provides user interface & supports for services such as e-mail, file transfer, access to the world wide web. So it provides services to different user applications.

Located at the lowest layer of the Open Systems Interconnection (OSI) communications model, the physical layer's function is to transport data using electrical, mechanical or procedural interfaces. Currently planned for release in 2019, the 802.11ax standard offers 10 Gbps speeds –up to 40% faster The Lower Layers: Physical, Data Link, Network The three lower layers of the OSI reference model are responsible for transferring the data between the end systems, hence constitute the communi-
