Stacie Rollins Monday , December 15, 2014 Nt 2640 Unit 1 Assignment 1 Network IDs used to be divided into classes, which were Class A, B, and C. These classes were allowed to have a range of addresses. This class-based system would work well for a while, but the rapid growth of the Internet it becomes evident that this addressing scheme had to be changed in order to support the many networks that were being created. A class full system would be created and still used the IP addressing fundament of a classless system. This 32-bit IP addressing system is subdivided into two portions; the network address space are the host address space. Class A addresses were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero.
Unit 1 IP Addresses Classes and Special-Use IP Address Space Network IDs used to be divided into classes, and these classes are Class A, B, and C. These classes were allowed to have a range of addresses depending subnet we are using. This class-based system would work well for a while, but with the rapid growth of the Internet it became evident that this addressing scheme had to be changed in order to support the many networks that were being created (CompTIA Network, Ch.7, 2009). This 32-bit IP addressing system is subdivided into two portions: the network address space and the host address space in IPv4. Class A were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero. The first octet (the left-most eight bits) is used to define the network ID.
In according to the PC market, Intel was allowed to place their logo on the computers but the cell phone manufacture market is not promised. Therefore, without being able to place the Intel Inside logo on cellphones might be detrimental for the company. Action Plan Short-Term 1. Create a marketing strategy by focusing on the manufactures to gain a greater market share. Even though there is high risk involved in the “wait-and-see” method (as it may be crucial to potential growth), the consumer response to the development of the mobile/PDA market is currently undetermined.
The amount of units that the data is sent in is called packets. Datagrams: Datagrams aren't very reliable because they work by themselves and also you aren't always guaranteed that your data will get to it's destination as a whole when you first sent it. This is were higher protocols come into play because they decide whether the data reaches it's destination. People who stream a lot such as, video, audio, voice use datagrams because it'll still be okay if a few are lost on the way. Addresses: An address is given to a computer by the router.
Doing this, the attacker will know which computers are alive and which aren’t so they know where they should concentrate their attacks on. On another note, network administrators also uses ping sweeps when they are scanning the network to troubleshoot problems or to identify which IP addresses are taken. For example, a company may need to set up some new network printers, so the network administrator need to assign the printers static IP addresses. To avoid any conflict with existing IPs on the network, they will do a ping sweep to determine which IPs are available. What is a port scan and how does it work?
Consumers aged 15 to 29 had poor credit quality and they were considered to be low users, therefore they were not as attractive to current players. The cost to acquire a customer was roughly $370 and the average monthly bill was $52. The average cost to serve one customer was $32. Virgin Mobile was able to identify this niche, its needs and where they usually bought for electronics. The company knew that these customers’ usage was inconsistent and that they did not like the confusion current rates created.
In general, demand for mobile phones as a whole is likely to be fairly price inelastic. This is largely because there are no particularly good substitute for mobile phones. There are other methodsof communication, such as e-mail and letter writing, but they tend to be poor substitutes.Landline phones are a potential substitute, but most people have both. Moreover, few people purchase more than one mobile phone - hence a change in price is unlikely to bring about additional or reduced demand by an individual for a mobile. At an earlier stage, when mobile phones were expensive to buy, and hence a luxury for most people, reductions in price did bring about a significant increase in demand (suggesting demand was then elastic).
It has made the world smaller and more connected than at any point in history, especially with the invention of iPads, iPhones, computers, and mobile devices. A disadvantage of easily obtainable information is whether the information is actually credible or not. Many people look for information on the Internet giving no thought as to whether the information is actually trustworthy or not. There are some sites that look like they have correct information yet they may not be affiliated with certain groups or entities that endorse the copy or the information that the site contains. Misleading information can cause people to make unwise decisions about all sorts of life’s struggles from financial issues,
The internet has made it hard for me to stay focused when reading things you can't learn quickly. Due to the Internet, my expectation of receiving information is to have it quickly and with little or no effort at all. If the influence of technology is to increase, the human brain will no longer be highly valued. "The human brain is just an outdated computer that needs a faster processor and a bigger hard drive."
Now, even our schools use e-mail to alert students of any news that they might need. When one thinks about what they do during a typical day, technology is present in most daily functions. From the coffee maker to an alarm clock to the computer at a desk, all of them are technology that has advanced to make things easier. The question is where technology should stop. For any who have lost their cell phone, they realize how dependant many are on something that is so small.
