Drag each tile to the correct box.

riadik2000 [5.3K]

Answer:

Make a copy of the original file as a new layer and work on this copy.
Create highlights on the new layer using the Dodge or Paintbrush tools.
Visualize the lighting you require and how it will interact with the different surfaces in the photograph.
Delete the untouched areas of the new layer using the Eraser tool.
Blend the two layers by changing the opacity of the upper layer.
Repeat this technique to add more highlights, adding a new layer each time.

Explanation:

To add light to the photograph, above mentioned steps are followed. In first step, a copy has been created to manipulate the image and blend this with original image after completion of lighting process. In next step, highlight the area on duplicate image that you want to light. Then add light effects that you want on your photograph. With the help of eraser tool, erase the untouched dark area and add some white background to change the opacity of the original layer. repeat this technique to add more highlights and the layers to meet the requirement.

Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such tha

kvv77 [185]

Answer and Explanation:

a)

For Go-Back-N:

Host A sent total number of segments is 9.The initial segment numbers are 1,2,3,4,5 and re-sent the segemnts 2,3,4 and 5 because 2nd segment was lost.

Host B sent the number of ACKs are 8.Host B sent ACKs 1 by four times because 2nd segment was lost and sent 4ACKs with sequence numbers 2,3,4 and 5

selective repeat:

Host A sent total number of segments is 6.The initial segment numbers are 1,2,3,4,5 and re-sent the segemnts 2 because 2nd segment was lost.

Host B sent the number of ACKs are 5.Host B sent four ACKs with sequence numbers 1,3,4,5 and re-sent ACK2 with sequence number 2 because 2nd segment was lost.

TCP :

Host A sent total number of segments is 6.The initial segment numbers are 1,2,3,4,5 and re-sent the segemnts 2 because 2nd segment was lost.

Host B sent the number of ACKs are 5.Host B sent four ACKs with sequence number 2 and There is one ACK with sequence number 6.TCP always send an ACK with expected sequence number

b) If the timeout values for all three protocol are much longer than 5*RTT,then TCP protocol successfully delivers all five data segments in shortest time interval.
