Understanding the TCP/IP protocol

Haha! In September 18, I will take the National Computer Level 3 examination. I apply for network technology. Some students say this is simple, and now I have a lot of contact with my computer, it is best to know something about the TCP/IP protocol.
I read some books today! Something about the TCP/IP protocol is found! I used to think that the TCP/IP protocol is a big one. What other protocols are included here? Today I know it is:

TCPTransmission Control Protocol): Transmission Control Protocol

IPInternet Protocol): internetworking Protocol

The sum of these protocols is called the TCP/IP protocol, which makes the most basic thing on the internet almost disappear without it!

Tcp protocol: It is responsible for decomposing sent data, breaking large data into small data packets, and breaking them into dozens of data packets ), then, add necessary information to each data packet, such as the data packet serial number, departure address, accept address, and error correction information );

IP protocol: responsible for transmitting data packets decomposed by the tcp protocol to the destination after analysis;

As shown in the following example:

A large machine needs to be transported to a distant location, but it is impossible to run it with a single means of transportation. Therefore, we will break down this machine into small pieces, each of which has a serial number, the destination address, the sender address, and several trucks are used to transport to the destination. After arriving at the destination, you can see the labels on each small block and find out where they come from. Then, based on the serial numbers, assemble the machine into a complete machine and work again. Hey!

Advantages and disadvantages of TCP/IP protocol:

Excellent: data can be transmitted through multiple channels without hanging on a tree.

Widowed: increases the volume of each data packet, resulting in a greater total of packets than the sent data packets. If the target machine processes slowly, hey! I can't imagine it!

Hey! Find the IP address definition in the original rfc 791!
