Course content

4 sections • 21 lectures • 1h 55m total length

Course Intro6:57
This lecture covers Layer 7 of the Open Systems Interconnect (OSI) Model, the application layer. This layer is responsible for identifying and establishing the availability of desired communication pier and verification of sufficient resources for communication.
7 Layers of the Open Systems Interconnect (OSI) Model - Layer 6-37:48
This lecture covers Layer 6 of the Open Systems Interconnect (OSI) Model, the presentation layer. Layer 6: Presentation is responsible for presenting the data in standard forms. Also this class covers Layer 5:Session layer, which is responsible for facilitating communication. Layer 4:Transport Layer, which is responsible for multiplexing upper layer applications. And Layer 3: Network layer, which is responsible for network paths.
7 Layers of the Open Systems Interconnect (OSI) Model - Layer 2-18:02
This lecture covers Layer 2 and 1 of the Open Systems Interconnect (OSI) Model. Layer 2: Data Link Layer, which is responsible for Logical Link Control and Media Access Control. Layer 1: Physical Layer is responsible for the flow of signals.
OSI Data Flow5:59
This lecture covers OSI Data Flow of the Open Systems Interconnect (OSI) which covers the layers of the data flow from the transmit to the receive.
Terminology6:17
This lecture covers Terminology Open Systems Interconnect (OSI). Terms will be explained to help understand.
Communication between layers, Layer 3 & 4 Examples, and Memory Mnemonics8:13
This class cover Communication between layers, Layer 3 & 4 Examples, and Memory Mnemonics of the Open Systems Interconnect (OSI). Communication layer, vertical communication, explains the data moving. Layer 3 and Layer 4 examples are shown. And Memory Mnemonics to help you remember previous terms.

Open Systems Interconnect Model Comparisons3:50
This lecture will compare the OSI Model, TCP/IP Model (DoD Model), and TCP/IP - Internet Protocol Suite
Application Layer Examples6:03
This lecture will give examples application layers by looking at the following protocols:
HTTP (80)
SNMP (161/162)
FTP (20/21)
TFTP (69)
SMTP (25)
Telnet (23)
NNTP (119)
We will then explain how to classify applications, devices & protocols relate to OSI model layers.

iPv4 Addresses and Base 2 Binary Numbers4:20
This lecture covers iPv4 and Base 2 Binary Numbers. IPv4 will cover the format, and Base 2 Binary Numbers explains how binary numbers work.
Decimal - Binary Numbers6:02
This lecture covers Decimal numbers and how they relate to Binary numbers
Why iPv4 Addressing Part 14:17
This class covers why to use iPv4 Addressing, this is part 1 of part 2.
Why iPv4 Addressing Part 26:40
This class covers why to use iPv4 Addressing, this is part 2 of part 2
The Big Picture (DNS, IPv4, MAC) Part 15:21
This class covers the big picture of DNS, IPv4, and Mac, this is part 2 of part 2.
The Big Picture (DNS, IPv4, MAC) Part 27:10
This class covers the big picture of DNS, IPv4, and Mac, this is part 2 of part 2.
Purpose and Properties of IP Addressing5:01
This class covers and explains the purpose of IP Addressing, and properties of IP Addressing.
iPv4 Bitwise Notation5:00
This class covers iPv4 Bitwise Notation, and walks through a bitwise representation.
IPv4 Classful Addressing Notation3:57
This class covers iPv4 Classful Addressing Notation, and demonstrates an example.
Subnetting4:38
This class covers Subnetting, the practice of dividing a network intro two or more networks.

Description

This course is a preview of the CompTIA Network+ Certification. It is designed for anyone who is looking to take Network+ preparation training or just anyone interested in networking technologies! More than ever, network security is needed to protect businesses from being breached as well as skilled IT professionals to harden and protect the integrity of today’s networks.

Learn the most important System Interconnection Models

This course will go over the following networking security concepts:

Open Systems Interconnect (OSI) Model – We start by going over the most popular System Interconnection Models, Open Systems Interconnect (OSI).
7 Layers of the Open Systems Interconnect (OSI) Model –
- 7) Application
- 6) Presentation
- 5) Session
- 4) Transport
- 3) Network
- 2) Data-Link
- 1) Physical
TCP/IP System Interconnect Model - This section will teach you the 4 layers of the TCP/IP System Interconnect Model and how they are applied in the real world.
- 4) Application Layer
- 3) Transport Layer
- 2) Internet Layer
- 1) Network Access
Open Systems Interconnect Model Comparison - This section will compare the OSI Model, TCP/IP Model (DoD Model), and TCP/IP - Internet Protocol Suite, as well as application layer examples.
