Write a program that uses the Die class that was presented in Chapter 4 to write a program that lets the user play against the computer in a variation of the popular blackjack card game. In this variation of the game, two six-sided dice are used instead of cards. The dice are rolled, and the player tries to beat the computer’s hidden total without going over 21. Here are some suggestions for the game’s design: Each round of the game is performed as an iteration of a loop that repeats as long as the player agrees to roll the dice, and the player’s total does not exceed 21. At the beginning of each round, the program will ask the user whether he or she wants to roll the dice to accumulate points. During each round, the program simulates the rolling of two six-sided dice. It rolls the dice first for the computer, then it asks the user if he or she wants to roll. (Use the Die class that was demonstrated in Chapter 4 to simulate the dice). The loop keeps a running total of both the computer and the user’s points. The computer’s total should remain hidden until the loop has finished. After the loop has finished, the computer’s total is revealed, and whoever the player with the most points without going over 21 wins.

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
