-# Osi tcp ip model
+# OSI and TCP/IP Models
 
-TCP/IP Model is a communication protocols suite using which network devices can be connected to the Internet. 
-On the other hand, the OSI Model is a conceptual framework, using which the functioning of a network can be described.
+The OSI and TCP/IP model is used to help the developer to design their system for interoperability. The OSI model has 7 layers while the TCP/IP model has a more summarized form of the OSI model only consisting 4 layers. This is important if you're are trying to design a system to communicate with other systems.
