Does TCP/IP need any any improvement or is there a need for a new model since TCP/IP was made for an outdated time and the power of today's networks?

That sounds like a homework question!
So, what do you think? (More importantly, what does your teacher think?)

Sorry, I guess I posted in a wrong place. You are right, that is related to my homework. Unfortunatley, I am not good in networking. I thought I can get some advise here... Anyway, thanks.

You can get advice and help here, however you cannot get tailor-made homework answers. We require you to put thought into it as well. However, if you do put effort in, we can help you refine your ideas.
So, what do you think? I'll start you out - what is one of the major features of TCP/IP? What is the main difference between it and another protocol such as UDP?
Thank you for giving me the opportunity to explore the networking. To my understanding, TCP/IP is the communication protocol for communication between computers connected to the Internet. It divides networking communication into 4 layers. The application layer (top layer) gathers the message or file into smaller packets and received by the other side of the application layer then resemble to original packets. The Network interfere layer (bottom layer) handles the IP address part of packets and send it to the assigned destination. UDP (User Datagram Protocol) is similar to TCP but UDP does not break the message into packets. Therefore is less reliable. Applications program that using UDP has to make sure they recognize the entire message. When networking program wants to save processing time, they might want to use UDP instead of TCP. UDP using port numbers to distinguish the different users and their request. And checksum is to verify the number of bits in the transmission unit to make sure the data is in one piece. But, I still don’t know if there is anything that TCP/IP can be improved?
Okay, why would using UDP be "better" in some cases over TCP/IP? Think VoIP, think 3-way handshake and ack's.
There are only two transport layer protocols that are used TCP and UDP .TCP/IP refers to the whole protocol suite. There are situation where UDP is better than TCP , e.g when doing video conferencing , the data has to be travelling faster the overhead for handshaking will cause the whole process to be slower.
