Question

Which field in a Transmission Control Protocol (TCP) header is not typically used in modern networking?

Answer 1

TCP stands for Transmission Control Protocol. It is the most commonly used protocol on the Internet. When you load a web page, your computer sends TCP packets to the web server's address, asking it to send the web page to you.

The only field it shares with TCP headers are the source and destination port fields, which are used to identify the application sheet.

Step-by-step explanation:

The header itself is considerably more complicated, This is not very surprising, as TCP is a significantly more complicated protocol that must keep each end of the connection informed (synchronized) about the current state.

Answer 2

The TCP receives the data which it receives from the data stream, and then it divides into chunks, and add the header to it to form a segment. And the segment header comprises ten mandatory fields. And among this ten extension field is also an optional extension field which is being termed as the Options. And this field can or cannot be included in the segment header. And in modern networking, it is avoided in general. However, now various network engineers have proposed several new applications of options, and consider it for addition of various new features or add ons to tackle various vulnerabilities.

Step-by-step explanation:

Its certainly the Options, which is a variable between 0-320 bits, and is divisible by 32, or in multiples of 8. And its length is being decided through the data offset field. And the options, in general, has around 3 fields or less. They are option length, option kind, and options data, and each of these is of 1 byte. Through the Option kind, we come to know about the option type we are in business with, and the option length is the overall length, and the options-data consist of the option's value, though only if relevant.
