Comparison of OSI and TCP/IP Reference Model

Now it's time to compare both the reference model that we have learned till now. Let's start by addressing the similarities that both of these models have.


Following are some similarities between OSI Reference Model and TCP/IP Reference Model.


Both have layered architecture.

Layers provide similar functionalities.

Both are protocol stack.

Both are reference models.

OSI(Open System Interconnection)TCP/IP(Transmission Control Protocol / Internet Protocol)
1. OSI is a generic, protocol independent standard, acting as a communication gateway between the network and end user.1. TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network.
2. In OSI model the transport layer guarantees the delivery of packets.2. In TCP/IP model the transport layer does not guarantees delivery of packets. Still the TCP/IP model is more reliable.
3. Follows vertical approach.3. Follows horizontal approach.
4. OSI model has a separate Presentation layer and Session layer.4. TCP/IP does not have a separate Presentation layer or Session layer.
5. Transport Layer is Connection Oriented.5. Transport Layer is both Connection Oriented and Connection less.
6. Network Layer is both Connection Oriented and Connection less.6. Network Layer is Connection less.
7. OSI is a reference model around which the networks are built. Generally it is used as a guidance tool.7. TCP/IP model is, in a way implementation of the OSI model.
8. Network layer of OSI model provides both connection oriented and connectionless service.8. The Network layer in TCP/IP model provides connectionless service.
9. OSI model has a problem of fitting the protocols into the model.9. TCP/IP model does not fit any protocol
10. Protocols are hidden in OSI model and are easily replaced as the technology changes.10. In TCP/IP replacing protocol is not easy.
11. OSI model defines services, interfaces and protocols very clearly and makes clear distinction between them. It is protocol independent.11. In TCP/IP, services, interfaces and protocols are not clearly separated. It is also protocol dependent.
12. It has 7 layers12. It has 4 layers

Tutorial on EasyEDA desktop software for PCB and schematic design

In this article, I am going to write a tutorial on how to use EasyEDA desktop application for creating a schematic and for PCB design. One of best advantage of this software is that you can create design offline and can automatically synchronize your design with your online EasyEDA account.  It can be used for circuits simulation, PCB deign and electronics circuits design. You can download EasyEDA desktop application by clicking on following link and it will work on windows 7 or its greater version. They are also releasing soon offline application OSX and Linux users. So keep visiting their website for more information.                                                    https://easyeda.com/page/download So let’s start and see how to design a schematic and PCB using EasyEDA offline desktop application. So first of all lets see how to create a schema...
