...The pros and cons to wired and wireless media The main difference between wired and wireless media is the data transmission is sent with the understanding that with wired media, the data is sent through wired cabling, and wireless is sent using a broadcast signal through the air. Wireless networking is actually sent through the air in the form of a radio wave. The distance that wireless information can usually travel about 150 feet indoors and 300 feet outdoors. (Fredman, 2013) When using wireless in a home or business, a major challenge to the transmission range would be obstructions such as walls. In order to send and receive information two main devices are needed; a wireless router and a wireless network interface card in a computer. Depending on the type of network that will be used, the expenses would vary. A wireless network can potentially be more expensive. The reason for this is because the security of data should be a main priority. Data that is sent through wireless transmissions by default is unsecure and anyone with a wireless device could connect and use the bandwidth of that access point. This is why securing a wireless access point is very important. Most wireless access points are ready with specific encryption methods. Wired Equivalent Privacy (WEP): This encryption allows 64 or 128 bit encryption and uses a word and converts it to hexadecimal. This encryption is possible to be hacked with the correct hacking tools...

...stand in line to pay for tickets for a concert that is literally two months away from now? But is everything we do in this advance world safe? Keeping up with the Future I have done some research on the similarities and differences between wired and wireless networks. I have learned what it takes to set up a network and some of the challenges of using the networks. I have also realized how much the wireless network has grown in the past 5 years. Ethernet vs. Wireless in todays’ World Ethernet would be referred to as your wired home network or your land line. The wireless network would be most commonly addressed as a Wi-Fi network system. Both the Ethernet and Wi-Fi connect you to internet services. However; the Ethernet service is much faster than the Wi-Fi service of speeds more than 1000 Mbps. The cost of the Ethernet network is much more expensive than the Wi-Fi because you have the coaxial cables that have to be installed all around the networks as opposed to Wi-Fi which is very easy to set up and the cost of setting up is very low. There are some pros and cons to having one connection over the other. The pros in Ethernet are more reliable, faster connection and transfers data at super speeds. On the other hand the pro of wireless network gives you more freedom to be mobile with no cables to connect even though its speed is a bit slower than...

According to Laudon and Laudon (2009), Internet networking standards and Web technology used to create private networks are called intranets. An intranet is private and secure and is protected by a firewall which prevents unauthorized individuals from entering the network. Intranet software technology and that of the WWW is the same. Having quick access to accurate information can be vital to a sales and marketing department. The sales and marketing department could benefit from using an intranet by being able to look up sales reports, product information, marketing analysis, and researching competitors are just one click away. The human resources department could benefit from having an intranet because they could eliminate using large amounts of paper. The human resources department could upload employee handbooks, benefits information, job listings and applications, newsletters, and new employee interactive training, as well as other information that would save paper costs. The manufacturing and production departments could benefit from...

...A Look at Wireless Networking Abstract Over the last several years technology has continued to evolve and grow exponentially. The need for wired and wireless networks has become vital in both individuals lives and in the work environment. There are several factors to consider when discussing wired and wireless technologies such as hardware requirements and security measures needed to ensure a secure network. Wireless network trends are now offering new technology such as cloud computing and simply being able to work from anywhere you want. As you read on you will understand the benefits of wireless technology in our personal lives and in work situations. A Look at Wireless Networking Many organizations such as universities, retail centers and your own office depend on the ability to share information in an efficient and useful way. Nowadays networks are an integral part of almost every business and in your own personal life. There are two options for setting up a network — wired and wireless. A wired network uses cables to connect to a computer and a wireless network uses radio frequencies to connect to a computer. The components required to set up a wired or wireless network are somewhat similar with a wireless network needing a few additional pieces. Wireless networks are allowing individuals and businesses to become more mobile. For example, people are able to work from home these days and can have a better work-life balance. Businesses such as Starbucks...

...So far we have studied the use of Distributed Control Systems in Frontier Refineries as a close example of the use of a SCADA-like system in the oil industry. Implementing the capability of satellites to these systems has allowed broadening their utilization potential to other industries, including government and military defense uses within the domain of national security. This can lead us to an analysis of the financial sustainability of these systems for the-at least for now-near future. Based on what we have learned about the oil industry-the need for continuous monitoring and control of diverse assets in the plant/field-we can conclude that the basic functions-pipeline, tank and pump monitoring, leak detection, etc-are operations that will maintain steady usage in spite of fluctuating financial conditions in the oil/gas market. We expect also that, given the conditions of international relations, the military and government need of SCADA systems for anti-terrorism and peacekeeping efforts will not be affected by variations in credit markets. In fact, the more this security around this technology is developed, the more we expect security-sensitive users such as the military will make use of them. We should also consider the possibility that a shift in international relations policies might dampen the demand growth rate for SCADA/Satellite systems. The sources studied for this report also make another consideration: the uncertain and variable situation in the Middle East...

...WEB vs WPA Matthew Otte Friends University Due to the nature of wireless, using radio waves instead of physical media to transferred data, anybody within range could receive the information being transmitted between devices. To successfully employ wireless technology, a solution had to be introduced to ensure security. Wired Equivalent Privacy (WEP) was introduced to meet this need. WEP is a means to secure Wireless Local Area Networks (WLANs) by encrypting transmissions at the data-link layer with the symmetric RC4 encryption algorithm. The main goal when employing WEP was to provide confidentiality, access control, and data integrity at an equivalent level as a wired connection, thus the name. These security standards were...
