Answer:

The answer is 1. Data offset

Explanation:

From the Question given, a device that receives a Transmission Control Protocol packet and also understands where the actual data payload begins is called the Data Offset

Data offset: This is the 4 bit data offset field, also referred to as the header length. It indicates the length of the TCP header so that we know where the actual data starts from or begins.

What is the difference between building a table in word and excel
Anastasy [175]

Answer:

 The main difference between creating a table in word and excel is that there are more number of table tool and the layout section in the excel as compared to the MS word.

Creating a table in word or excel are only depend on the requirements of the particular table. If there is less number of calculations in the table then, it is easy to create the table in word as compared to excel.

And if we want to create a table with maximum numbers of rows and column and also contain high math calculation then, it is good to create in excel.
