OSI model TCP/IP

OSI (Open Source Interconnection)
TCP/IP (Transmission Control Protocol/ Internet Protocol

The OSI model consists of seven layers and is part of the networking vocabulary.
The TCP/IP works in the first 3 layers of the OSI model.

Protocols provide all the rules necessary to carry out all the duties within the OSI model.

I was taught that an easy way to remember the seven layers in the OSI model is:
All    -    Application
People    -    Presentation
Seem    -    Session
To    -    Transport
Need    -    Network
Data    -    Data Link
Processing    -    Physical

 I was given the following videos to use. I uploaded theses video's from Youtube.com and intend to use them for my studies  in Web Development.

 

Some things that I have noted from class.

The physical layer deals with 0's and 1's from the ASCI code converting between binary and numbers.The physical layer is also used to connect your cables.

The physical layer deals with hardware, no software. example: hubs,and physical parts to the network.
