Gerard is currently working as an entry-level customer support technician, but he would like to someday become a software developer. what is the best first step to understand what he should do? ask his manager for a new job or at least a job recommendation study graphic design in order to obtain the necessary skills use career resources to investigate what skills and education are required work part-time as an entry-level web developer question 13 (true/false worth 6 points) (08.03 lc) career resources are used to explore career options and find career information. true false question 14(multiple choice worth 6 points) (08.01 mc) classify the following skills: writing html code, evaluating color theory, using design principles. hard skills interpersonal skills people skills soft skills question 15 (true/false worth 6 points) (08.03 lc) a mentor is a person who is advised, trained, or counseled by a trusted mentee. true false

A911 dispatcher is the sole sender of messages to all police officers. while on patrol, officers communicate with the dispatcher who, in turn, relays messages to other officers. the officers do not communicate directly with one another. this illustrates a network.

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?
