Design a finite state machine that determines the least recently used number in a set. For this FSM, the set of numbers is (0, 1, or 2). For example, for the sequence 0, 1, 0, 2, 0, 2, where the left-most number is the first number to appear in the sequence, the least recently used number would be 1 because 0 and 2 were both used more recently than 1. Your FSM receives a 2-bit unsigned binary number (ab) that encodes the values 0, 1, or 2. Each cycle your FSM must output the 2-bit unsigned binary number (xy) that indicates which number was least recently used. Your start state should use the assumption that the numbers 0, 1, 2 were previously seen in that order, making 0 the least recently used number. If an illegal number that is not part of the set is received as an input, return to the same state.

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.
