1. Consider a planet where everyone belongs to a family of six, every family lives in its own house, each house has a unique address, and each person in given house has a unique name. Suppose this planet has a mail service that delivers letters from source house to destination house. The mail service requires that (1) the letter be in an envelope, and that (2) the address of the destination house (and nothing more) be clearly written on the envelope. Suppose each family has a delegate family member who collects and distributes letters for the other family members. The letters do not necessarily provide any indication of the recipients of the letters. a) Describe a protocol that the delegates can use to deliver letters from a sending family member to a receiving family member. b) In your protocol, does the mail service ever have to open the envelope and examine the letter in order to provide its service? 2. Consider you have 10 data packet from 0 to 9. In Go-back-N and Selective repeat both have window size of 5. While transferring packet, ACK2 is lost. What will happened then?

Assume that minutes is an int variable whose value is 0 or positive. write an expression whose value is "undercooked" or "soft-boiled" or "medium-boiled" or "hard-boiled" or "overcooked" based on the value of minutes. in particular: if the value of minutes is less than 2 the expression's value is "undercooked"; 2-4 would be a "soft-boiled", 5-7 would be "medium-boiled", 8-11 would be "hard-boiled" and 12 or more would be a "overcooked".
