Everything about the 7 Layers of OSI Model

In this course, you learn about the basics of network communication. All about how the data is transferred on the network and logical addressing to communicate on the network. Dhananjay has tried demystifying the concepts of network communication through the 7 layers of the OSI model.

Following topics are covered -

1. Physical Layer

   • Understanding the basics of data transmission

   • Different types of cables (e.g., copper, fiber optics)

   • Connectors (e.g., RJ45)

   • Voltage levels and signaling

   • Data rates and bandwidth

2. Data Link Layer

   • Introduction to MAC addresses

   • Ethernet and Ethernet frames

   • Error detection and correction

   • ARP (Address Resolution Protocol)

   • PPP (Point-to-Point Protocol)

   • Switching and bridging

3. Network Layer

   • IP addressing (IPv4 and IPv6)

   • Routing protocols (e.g., RIP, OSPF)

   • Subnetting and CIDR

   • ICMP (Internet Control Message Protocol)

   • NAT (Network Address Translation)

   • VLANs (Virtual LANs)

4. Transport Layer

   • TCP (Transmission Control Protocol)

   • UDP (User Datagram Protocol)

   • Port numbers

   • Flow control

   • Error detection and correction

   • Multiplexing and demultiplexing

5. Session Layer

   • Session establishment, maintenance, and termination

   • Checkpointing and recovery

   • Synchronization

   • Session-layer protocols and APIs

6. Presentation Layer

   • Data compression

   • Encryption

   • Data translation and formatting

   • Character encoding (ASCII, Unicode)

7. Application Layer

   • HTTP (Hypertext Transfer Protocol)

   • FTP (File Transfer Protocol)

   • SMTP (Simple Mail Transfer Protocol)

   • DNS (Domain Name System)

   • Client-server architecture basics
