Imagine that we can quarantine infected members of the population, so that they are unable to transmit the disease to others. let q represent the fraction of the infected population which is quarantined, and let 1-q represent the fraction of the infected population that is not quarantined and can transmit the disease to the susceptible individuals. a. rewrite the difference questions for s[t 1] and i[t 1] (from question 1), to incorporate the effects of quarantine. (hint: quarantine should affect the term representing the proportion of susceptible individuals who are infected each time step) b. quarantine can be viewed as a way of modifying the transmission coefficient (a) by reducing the number of individuals which can be infected. this modified transmission coefficient can be referred to as a'. write an equation for a' that incorporates both a and q.

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.
