OSI 7 Layers Table with Protocols and Devices

-

The OSI model divides computer networking into seven logical layers. Each layer has a unique purpose, related protocols, and network devices. The table below summarizes the OSI 7 layers with clear examples of protocols, PDUs, and devices used at each level.

OSI 7 Layers Explained with Protocols, PDU, and Devices
Layer Description Protocol PDU Devices
Application - Interacts between user and network application.
- API - set of routines that make up part of a software application		 HTTP, FTP, IMAP, SNMP, POP3, SMTP Data Chrome, Firefox, Skype
Presentation - Formats the data of application/network to be presented for the destination to be sent.
- It can be viewed as the data translator between the application and network.
- Character set translation
- Data conversion
- Data compression
- Data encryption or decryption (if needed)		 SSL, TLS
Session - Establishes a session between two nodes.
- Connection maintenance and termination
- Synchronization
- Dialog control
- Send to ports		 H.245, RTCP, SCP, SDP Logical Ports
Transport - Ensures that the entire message is delivered to the destination or not.
- Service point addressing
- Segmentation & reassembling
- Connection control
- Flow control
- Error control		 TCP, UDP Segment
Network - Controls the operations of the subnet, deciding which physical path the data takes.
- Logical addressing
- Routing
- Handling congestion issues
- Internetworking		 IP (IPv4, IPv6), ICMP, IPsec, MPLS, ARP Packet Routers
Data Link - NIC – Switch – NIC
- Deals with data transfer
- Framing
- Physical addressing
- Access control
- Flow control
- Error control		 Ethernet, PPP, ATM, CDP Frame Switch, Bridge
Physical - Concerned with the transmission and reception of the unstructured raw bit stream over the physical medium.
- Media characteristics
- Data encoding
- Transmission mode		 Bluetooth, DSL, 802.11, Wi-Fi, ISDN Bits Repeater, Coax, Fibre

This OSI 7-layer table serves as a quick reference for students and IT professionals preparing for networking certifications like CCNA, CompTIA Network+, or just learning fundamental data communication concepts.

If you're a frequent user of SecureCRT , backing up your session settings and restoring them later is crucial—especially when migrating to a new PC or recovering from a crash. In this guide, you’ll learn how to manually back up and restore SecureCRT settings on Windows , ensuring you never lose your configurations again. Does SecureCRT Have a Built-in Export/Import Feature? Yes, SecureCRT provides built-in export and import features in the Tools menu. However, these features may not capture all configuration details such as: Backup scripts Custom login scripts Certain session-specific files Therefore, if you want to completely clone your SecureCRT environment—including every session and customization—the safest option is to manually back up the entire Config folder. What Is the SecureCRT Config Folder? SecureCRT stores your personal settings (sessions, host keys, global options, etc.) in a folder located at: C:\Users\<Your username>\AppData\Roaming\VanDyke\Config Th...

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
