A holiday company uses spreadsheets to organise the holidays they offer for scuba divers. In the first two columns, there is a list of holiday codes together with the accommodation offered. Also in the spreadsheet, there are formulae to manipulate the data stored elsewhere in the spreadsheet. There is also space to calculate the number of weeks and days each type of holiday has been booked for. (a)What type of holiday would you expect to see in D5?(1) (b)What value would you expect to see in F5?(1) (c)What formula would you expect to see in G2?(2) (d)What formula would you expect to see in H2?(2)Immersive Reader (6 Points)

Identify at least three types of characteristics that you were asked about as you the computer identify a fruit.

Consider a slotted aloha system, where the time slot equals the fixed duration of each packet. assume that there are 4 stations a,b,c,d sharing the medium. (a) stations a,b,c,d receive one packet each from higher layers at times 1.3, 1.5, 2.6,5.7 respectively. show which transmissions take place when, according to the slottedaloha protocol; describe all transmissions until all four packets have been successful.when needed, each station has access to the following sequence of random number, provided by a random number generator and drawn uniformly between 0 and 1: (1) station a draws numbers: 0.31, 0.27, 0.78, 0.9, 0.9, 0.11, 0. (2) station b draws numbers: 0.45, 0.28, 0.11, 0.83, 0.37, 0.22, 0. (3)station c draws numbers: 0.1, 0.2, 0.3, 0.4, 0. (4) station d draws numbers: 0.36, 0.77, 0.9, 0.1, 0.1, 0.1, 0.1, 0. (b) in slotted aloha, a station transmits in each time slot with a given probability. what probabilities would you assign to each of the four stations so as to: (i) maximize the efficiency of the protocol? (ii) maximize fairness among the four stations? (c) will the efficiency increase or decrease if we modify slotted aloha as follows: (i) get rid of slots and allow stations to transmit immediately? (ii) implement carrier sensing? (iii) implement collision detection? (iv) implement collision avoidance?
