The main drawback of TCP (Transmission Control Protocol) as compared to UDP (User Datagram Protocol) is its high overhead.

TCP is a connection-oriented protocol, which means it establishes and maintains a dedicated connection for the duration of an exchange. This involves a number of steps:

1. Connection establishment: Before any data can be sent, the sender and receiver must establish a connection using a process known as a three-way handshake.

2. Data transfer: Once the connection is established, data can be sent from the sender to the receiver. TCP ensures that all data arrives correctly and in the right order.

3. Connection termination: After all data has been transferred, the connection must be closed using a process known as a four-way handshake.

Each of these steps requires the exchange of a number of control packets, which adds to the overhead of the protocol. In contrast, UDP is a connectionless protocol, which means it does not establish a dedicated connection and does not guarantee the delivery or order of data. This makes it much more lightweight and efficient than TCP, but also less reliable.
