8. Question

A device receives a Transmission Control Protocol (TCP) packet. The

device understands where the actual data payload begins. Which

portion of the TCP header provides this information?

A

Data offcat.

Data offset field

Step-by-step explanation:

The data offset field is used to store the size of the Transmission Control Protocol (TCP) header. The size of the Transmission Control Protocol (TCP) header is stored using a four bit number so that the receiving network device understands where the actual data payload begins. The minimum size of the header has 5 data offset words (representing 20 bytes) while the maximum size of the header has 15 data offset words (representing 60 bytes).

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
