4.●Let us now see how randomization is done when a collision occurs.After a(71),time is divided into discrete slots whose length is equal to the worst-case round-trip propagation time on the ether(2τ). To accommodate the longest path allowed by Ethernet, the slot time has been set t0 512 bit times, or 51.2μsec.After the first collision, each station waits either 0 or l (72) times before trying again. If two stations collide and each one picks the same random number, they will collide again. After the second collision, each one picks either 0,1,2,or 3 at random and waits that number of slot times. If a third collision occurs (the probability of this happening is 0.25), then the next time the number of slots to wait is chosen at (73) from the interval 0 to 23-1.In general, after i collisions,a random number between 0 and 2i-1 is chosen, and that number of slots is skipped. However, after ten collisions have been reached, the randomization (74) is frozen at a maximum of 1023 slots. After 16 collisions, the controller throws in the towel and reports failure back to the computer. Further recoveryis up to (75 )layers.(71) A．datagramB．collisionc．connectionD． service(72) A．slotB．switchC．processD．fire(73) A．restB．randomC．onceD．odds(74) A．unicastB．multicastC．broadcastD．interval(75) A．localB．nextC．higherD．lower

    问答题
    Judy plans to visit the National Gallery once each month in 2012 except in July and August when she plans to go three times each. A single admission costs $3.50, a pass valid for unlimited visits in any 3-month period can be purchased for $18, and an annual pass costs $60.00. What is the least amount, in dollars, that Judy can spend for her intended number of visits? dollars

    正确答案： 49.50
    解析：
    根据题干可知，2012年，Judy共打算参观国家美术馆 16 次，那么根据题意，每次都购买入馆费的话需要花费16×$3.50=$56,这显然比办理年卡（$60.00）花费少；假如Judy在6-8月期间办理月卡，其余月份每次支付入馆费，那么她的总花费为$18+(9×$3.50)=$49.50；由此可见，最少的花费为$49.50。
