Comparison of OSI and TCP/IP Model
OSI model is a seven-layered model which is strictly layered, has less credible and service interface and protocols are clearly distinguished whereas TCP/IP model is 4 layered model which is loosely layered, has more credible and service interface and protocols were not clearly distinguished before.
Summary
OSI model is a seven-layered model which is strictly layered, has less credible and service interface and protocols are clearly distinguished whereas TCP/IP model is 4 layered model which is loosely layered, has more credible and service interface and protocols were not clearly distinguished before.
Things to Remember
- OSI is seven-layered.
- TCP/IP is four Layered.
- The network layer provides both connectionless and connection-oriented services and Transport Layer provides only connection-oriented service in OSI model.
- Internet layer provides connectionless service and Transport Layer provides both connection-oriented and connectionless service in TCP/IP model.

Comparison of OSI and TCP/IP Model
OSI Model TCP/IP Model
| It is seven-layered | It is four Layered |
| Internetworking not supported | TCP/IP supports internetworking |
| Strict layering | Loosely layered |
| The network layer provides both connectionless and connection-oriented services. | Internet layer provides connectionless service. |
| Transport Layer provides only connection-oriented service | Transport Layer provides both connection-oriented and connectionless service. |
| Layer was first developed than protocol | Protocol were first developed than layer |
