To begin

 

Although computers can exchange data with each other through a variety of data transmission methods, by definition, communication needs to transmit information to the receiving end. Communication protocol is similar to a language, which allows computers to communicate with each other, so as to receive computers including data sent to them. TCP / - IP standardizes the communication process by providing a general protocol for all computers on the Internet so as to communicate with each other on the Internet.

Interoperability

As in human communication, computers can communicate with each other in many languages. Some protocols may be more suitable for some private networks than TCP / IP. However, TCP / IP even allows these networks to connect to the Internet. In addition, it allows computers and devices with different hardware structures and operating systems to communicate with each other. This means that a computer running Windows can connect to a web server rotating under Linux to browse to the web web web web web web web web web web web web web web web It is quite similar to the use of English as an international language today.

address

TCP / - IP assigns a single address to each computer on the network, called an IP address. Therefore, each computer in the network can be uniquely identified and can send information by simply addressing its IP address.

Communication with the TCP / / IP protocol starts with a connection between two computers. This is a systematic process, called TCP three routes. The computer starts communication and sends the packet connection request to another computer. If the computer has the correct IP address, it sends a feedback packet. If the first computer receives the packet, it sends one of them to the second computer, whose reception establishes a connection. Then, by using the established connection to exchange information, the harm to data is reduced.

Another  advantages of TCP/IP protocol are

1. It is an industry–standard model that can be effectively deployed in practical networking problems

1. It is interoperable, i.e., it allows cross-platform communications among heterogeneous networks.


2. It is an open protocol suite. It is not owned by any particular institute and so can be used by any individual or organization.


3. It is a scalable, client-server architecture. This allows networks to be added without disrupting the current services.


4. It assigns an IP address to each computer on the network, thus making each device to be identifiable over the network. It assigns each site a domain name. It provides name and address resolution services.

The disadvantages of the TCP/IP model are

1. It is not generic in nature. So, it fails to represent any protocol stack other than the TCP/IP suite. For example, it cannot describe the Bluetooth connection.


2. It does not clearly separate the concepts of services, interfaces, and protocols. So, it is not suitable to describe new technologies in new networks.


3. It does not distinguish between the data link and the physical layers, which has very different functionalities. The data link layer should concern with the transmission of frames. On the other hand, the physical layer should lay down the physical characteristics of transmission. A proper model should segregate the two layers.


4. It was originally designed and implemented for wide area networks. It is not optimized for small networks like LAN (local area network) and PAN (personal area network).


5. Among its suite of protocols, TCP and IP were carefully designed and well implemented. Some of the other protocols were developed ad hoc and so proved to be unsuitable in long run. However, due to the popularity of the model, these protocols are being used even 30–40 years after their introduction.
