Implement a PDASimulator based on the above given Java programs to model a pushdown automaton. Your PDASimulator should implement the Automaton interface provided above. It should utilize a Stack data structure (such as java. util. Stack). It should have a Character type attribute to indicate the character stored at the bottom of the Stack. The processInput(String input) will take a string as an input to a PDA and the PDA processes it to return whether or not the input is accepted. Hint: you may create a constructor for this class to take a PDAState object as its initial/START 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.
