How network protocols function at the OSI layers

# data[].attributes.body
Now that you know the OSI model’s layers, here are some examples of how specific network protocols function at each layer:

Physical layer network protocols

Common physical layer protocols specify standards for transmitting raw bit streams between two network nodes connected physically.

Physical protocols include:

Ethernet Physical Layer: Handles electrical signaling, cabling like Cat 5 and fiber optic connections.

Wi-Fi Physical Layer Standards: Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol standards encompass wireless transmission over radio frequencies along with modulation schemes.

Data link layer network protocols

The data link layer manages node-to-node communication, turning raw physical transmissions into orderly, addressed frames via protocols handling synchronization, error checking, flow control, and more.

Examples include:

Ethernet Data Link Protocols: IEEE 802.2 Logical Link Control (LLC) and IEEE 802.3 Medium Access Control (MAC) jointly handle physical addressing, frame synchronization, and error detection.

Point-to-Point Protocol (PPP): Enables direct serial data links between nodes by formally encapsulating datagrams with error detection and optional compression.

What Are Network Protocols and How Do They Work?

# data[].attributes.attachment_link.description
Network protocols act as common languages allowing devices to exchange data reliably. Understand what protocols are and how they deliver connectivity.

Data transmission is the transfer of data from one digital device to another. This transfer occurs via point-to-point data streams or channels. These channels may previously have been in the form of copper wires but are now much more likely to be part of a wireless network.

As we know, data transmission methods can refer to both analog and digital data but in this guide, we will be focusing on digital modulation. This modulation technique focuses on the encoding and decoding of digital signals via two main methods parallel and serial transmission.

The effectiveness of data transmission relies heavily on the amplitude and transmission speed of the carrier channel. The amount of data transferred within a given time period is the data transfer rate, which specifies whether or not a network can be used for tasks that require complex, data-intensive applications.

Network congestion, latency, server health, and insufficient infrastructure can bring data transmission rates to a sub-par level, affecting overall business performance. High-speed data transfer rates are essential to processing complex tasks like online streaming and large file transfers.

network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.
