TCP IP Model



TCP/IP Model is a rule or “Protocol” that determines how information is organized, sent and translated in a computer network. This model is based on today's internet, mainly paid for by 4 s.

On the other hand, OSI Model (Open Systems Interconnection) is paid by 7 properties, it will be used to understand network communication at theoretical level.

Major Differences Between TCP/IP and OSI
The difference between the two models is mainly based on the number of properties and the way they combine information.

Comparing the s ( s)
OSI 7 properties have been added to TCP/IP and replaced by 4 properties.

1. Application : The top three parts in OSI (Application, Presentation, and Session) will be rolled under one Application in TCP/IP. Protocols such as HTTP, FTP and SMTP can be found here.

2. Transport : It has the same name in both models. It is the part where you make sure the information is accurate. (TCP and UDP hold protocols).

3. Internet (in OSI 'Network'): In TCP/IP it is called "Internet " and in OSI it is called "Network ". The main task is to send information in the right way (Routing) using IP Address.

1. Network Access (via OSI 'Data Link' and 'Physical'): OSI's Lower Two Networks (Data Link and Physical) in TCP/IP under Network Access . This also controls physical communication through cable or wifi.

Why is TCP/IP used so much?.

Implementation: TCP/IP was built to be direct for work (Implementation) so this is how the internet world we are in.

Transitability: Can work without choosing any hardware or operating system (OS).

In short, OSI is a "map" that helps you learn in detail about the network, but TCP/IP is the "language" that computers use to connect with each other.
