Layer 1 (Physical): Actual hardware sits at this layer. It transmits signals over media. The TCP/IP model, sometimes referred to as a protocol stack, can be considered a condensed version of the OSI model. Layer 1 (Network Access): Also called the Link or Network Interface layer. This ...
At Layer 1, the Physical layer of the OSI model is responsible for the ultimate transmission of digital databitsfrom the Physical layer of the sending (source) device over network communications media to the Physical layer of the receiving (destination) device. Examples of layer 1 technologies in...
Layer 1: Physical Layer The Physical Layer serves as the foundation of the OSI Model, focusing on the actual transmission of data in its raw bit form over a physical medium. Its essential functions encompass: Encoding and Signaling: Encoding bits into electrical or optical signals suitable for...
Layer 2 Data Link examples include PPP, FDDI, ATM, IEEE 802.5/ 802.2, IEEE 802.3/802.2, HDLC, Frame Relay. OSI Layer 1: Physical OSI Model Layer 1, or the physical layer, conveys the bit stream—electrical impulse, light, or radio signal—through thenetworkat the electrical and mechanical...
examples of data link protocols are HDLC and ADCCP for point-to-point or packet-switched networks and Aloha for local area networks. On IEEE 802 local area networks, and some non-IEEE 802 networks such as FDDI, this layer may be split into a Media Access Control (MAC) layer and the ...
Examples of protocols operating at the Application Layer includeHypertext Transfer Protocol (HTTP)for web browsing, File Transfer Protocol (FTP) for file transfers, Simple Mail Transfer Protocol (SMTP) for email services, and Domain Name System (DNS) for resolving domain names to IP addresses. Thes...

Ethernet, Wi-Fi, and Bluetooth are all examples of protocols that cover the data link layer. The MAC address of your computer’s network interfaces is associated with the data link layer. Layer 3: Network Layer The network layer provides functionality for transmitting packets between networks. Th...
When an application on one computer starts communicating with another computer, then the Application layer is used. The header contains parameters that are agreed between applications. This header is often only sent at the beginning of an application operation. Examples of services within the ...
7. Application Layer The application layer is used by end-user software such as web browsers and email clients. It provides protocols that allow software to send and receive information and present meaningful data to users. A few examples of application layer protocols are theHypertext Transfer Pro...
