In Go-Back-N and Selective Repeat, assume that the timeout values are sufficiently long such that 5 consecutive data packets and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively. Suppose Host A sends 5 data packets to Host B, and the 2nd packet (sent from A) is lost. No packet loss occurs during retransmission, and in the end, all 5 data packets have been correctly received by Host B. How many packets has Host A sent in total and how many ACKs has Host B sent in total with Go-Back-N and Selective Repeat, respectively? Please explain.

Carlos, an algebra teacher, is creating a series of powerpoint presentations to use during class lectures. after writing, formatting, and stylizing the first presentation, he would like to begin writing the next presentation. he plans to insert all-new content, but he wants to have the same formatting and style as in the first one. what would be the most efficient way for carlos to begin creating the new presentation? going under the file tab and opening the first presentation, deleting all content from each page, and adding new content going under the file tab and clicking on new in the left pane, then choosing new from existing going under the design tab and clicking on themes, then selecting the theme that was used for the first template going under the design tab and opening the template that was created for the first presentation
