Question 2: determine the DWI components needed to complete the DWV system for the bathroom shown in figures below. The horizontal waste piping is 2 feet below the

and the second path is where ten is added to the value of the entrance and then the subtraction occurs. On the side you can see a series of logic gates that generate a function that will produce an output of 1 only when digit 1 of the exit is bigger than that of the entrance. This output will be sent to two different multiplexers, one for each digit. In the digit 1 diagram it will be sent to a multiplexer that will decide whether to use the subtraction where the entrance has been increased by 10 or whether to use the other where the entrance has had no alteration. If it is a 1, then it will use the first option where ten was added to the entrance. If it is a zero, then the latter will be used. This can be seen below in figure 2.

Overflow occurs when the two numbers of similar signs are added together and a result with an opposite sign is produced.

One of the largest features in Java 8 was the ability to stream over collections of objects. By adding the .stream()-method into the Collection interface, every collection in the java language was suddenly expanded with this new ability. Other data structures like the Map-interface, does not implement the method as they are not strictly speaking collections.

Wireless communication helps businesses more easily stay in touch with customers, suppliers, and employees and provides more flexible arrangements for organizing work. Wireless technology has also created new products, services, and sales channels. If one requires mobile communication and computing power or remote access to corporate systems, you can work with an array of wireless devices: cell phones, personal digital assistants (PDAs), and smart phones. Personal computers are also starting to be used in wireless transmission. Mobile laptop computers equipped with wireless network interface cards link to the wired LAN by communicating with the access point. The access point uses radio waves to transmit network signals from the wired network to the client adapters, which convert them into data that the mobile device can understand. The client adapter then transmits the data from the mobile device back to the access point, which forwards the data to the wired network.

802.11n (2.4GHz or 5GHz) When 802.11n was introduced in 2009 with the ability to communicate at speeds up to 600Mbps, 802.11n also included the ability to work in either the 2.4GHz or 5Ghz spectrum. In this project we have used IEEE 802.11n standard, because our antenna is designed for 5GHz ISM frequency band for Wi-Fi application. Bandwidth requirement for Wi-Fi is 100MHz for that operating frequency band shown in table 1.1.

You go to Wal-Mart, Radio Shack, Office Max, Fry’s, or any of the 100’s of places that sell wireless routers and you are wanting to buy the best router for you, however you are at a crossroad. You now find that there are three types of wireless routers B, G, and N, but what one is the right one for you? Don’t know what is the difference, is it out of date, and is there an option for just reading email and basic internet information. Oh you play games and watch a lot of videos. Is the router you pick the right one for your needs?

Wi-Fi networks use radio technologies called IEEE 802.11 a, 802.11 b or 802.11 g to provide secure. Reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet and to wire networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, with an 11 Mbps (802.11 b) or 54 IV1bps (802.11 a) data rate.

It is appropriate for an organization to have an idea on the basic functioning and installation of the LAN and Wireless LAN (WLAN) Wiring Considerations. Focusing on the wireless LANs, they are often the hosts into which the WLANs are connected to. In the process of their installation and maintenance, various processes are involved that include antenna policy, rate of recurrence of the frequencies and the communicating transmitters (Kahmen et. al., 2008).

Consumer grade equipment that is used in most home network installations, is manufactured to support fairly small environments. Small environments are networks with about five to ten devices connected at the most, at one time. Enterprise grade equipment is created to support large corporate networks with large amounts on users. In the past, corporate wireless networks used multiple access points to ensure continuous connectivity. Today, wireless networking has evolved to enable the use of wireless controllers. Wireless controllers connect access points by using the same SSID and channel for each, which enables uninterrupted connectivity. The wireless controller is the wireless gateway. Corporate networks are established in a similar but more complex architecture as home networks. Networks utilizing a wireless controller base their infrastructure off of a hub and spoke or distributed mesh setup.

A key benefit of both wireless routers is scalability.   Their strong built-in transceivers are designed to spread a wireless signal throughout the home.   A general rule of thumb in home networking says that 802.11b and 802.11g WAPs and routers support a range of up to 300 feet, but obstructions in a home such as brick walls and metal frames can reduce the range of a Wi-Fi LAN by 25%

More companies today use wireless local area network because it can help improve their productivity. Having a single broadband network allows employees to have access to their computers anywhere in the office, and connect to wireless printers when available.

Technological advancement in wireless communications has led to the worldwide proliferation of networks. The various kinds of network

Continual advancement in technology has led to the extension of wireless accessibility due to Wireless Fidelity (Wi-Fi), an important phenomenon that has been impacting the world over the past decade (Kioskea, 2015). The name Wi- Fi was first coined by Wi-Fi Alliance and it refers to wireless Ethernet 802.11 which defines standards for wireless local area networks (WLANs). But since 802.11 was considered too slow for some applications it was surpassed by extensions 802.11a and 802.11b, and later by 802.11g. Traditionally, this radio technology that uses frequency to transmit data through air was initially originated during late 1980s and was evolved with the fundamental objective of making data communication wireless. But today Wi-Fi has become a necessity for both consumer and enterprise since it does not only represent a means of staying connected at home or at the internet and checking emails and surfing the web, it is also consumed by the users for content purposes such as streaming music and high

In this modern era, wireless communication has become a requisite need like water and electricity which is part of our personal as well as our professional life. When we talk about wireless communication, the first word which comes to our mind is Wi-Fi. It uses 2.4-5 GHz RF (radio frequency) to deliver internet access around a wide area. As more and more users are connected to the network, the rate of data transfer gets reduced. So when more people access wireless internet, airwaves gets clogged and it makes difficult to latch onto a reliable signal. Transmission of data is done using radio waves which is just one part of spectrum. We are totally dependent upon this very prevalent service. But it has also many
