...Williams Strayer University Computer Threats Professor Richard Carroll June 18, 2010 The worst thing about computers are the bugs and viruses. There is a myriad of information and opportunities on the internet but if you do not have adequate protection it will be the same as if your were crossing an intersection blind folded. In the beginning when email had become popular one of the worst things what would happen was that someone would intercept your message and use that information for illegal gain. Then came the bugs or viruses that would be secretly embedded in your attachments. Now we have threats that are far worse than anything I would have ever imagined. There are people for who knows what reason, who creates programs just to shut down computer networks. It is true that not every instance of a bug or virus is about money. I had a professor who has a family member who not only wrote viruses and sent them out, but was also a collector of computer viruses. For the life of me I still cannot figure out why. Then there are the people who do this for monetary gain. These people have ways that are unimaginable for you and I to think of ways to steal personal information from others. Look at the social websites like Face book, Twitter and MySpace just to name a few. People are putting all types of personal information on these sites. We believe that these sites are harmless and who would care about what schools we graduated from or what cities we live in. But little...

...Case Project 3-1 Old-Tech Corporation has 10 computers in its main office area, which is networked in a star topology using 10 Mbps Ethernet hubs, and wants to add five computers in the manufacturing area. One problem with the existing network is data throughput. Large files are transferred across the network regularly, and the transfers take quite a while. In addition, when two or more computers are transferring large files, the network becomes unbearably slow for users. Adding the manufacturing computers will only make this problem worse and result in another problem. Because the ceiling is more than 30 feet high, there’ s no easy way to run cables to computers, and providing a secure pathway for cables is next to impossible. Devise a solution to this company’ s networking problems. As part of your solution, answer the following questions: ● What changes in equipment are required to bring this company’ s network up to date to solve the shared-bandwidth problem? Removing the bridges from each computer removing the Bus topology and removing some of the cable usage with a extended star topology; that way everyone has shared files and their protected with supervision of the administrator. May need to upgrade cable however (details of size unknown). ● What topology and which type of device can be used in the manufacturing area to solve the cabling difficulties? An extended start topology would be the best choice in my opinion because they will have less cables running...

...most beneficial. Showing how each job ranks and how I qualified each job will also be shown in this paper. In the end you will see which job actually meet my standards and why I chose the job that I chose. Information Technicians, Cybercrime Investigators and Web Technicians are the careers that I closed took write about. I chose these three careers because they each have something in common. They all require the use of some type of computer. The only difference is the person doing the job, type of computer and what needs to be worked on. Each job was based on a certain criterion and from that I can determine which of the three categorized jobs was better for me or someone else to do that catered to my independent job category and what I prefer to do or of each one. Basically, it's a rating of a job like I would compare cars or a mortgage. Each of the three jobs had a rating and a Weighted Score. All of the jobs I had, I had to rate on a scale of benefits, environment, hours, location, Outlook, qualifications and salary. Then based on the totals determined which one of the three jobs would best fit me for my area of expertise the best and be best in my comfort zone.

... * What changes in equipment are required to bring this company’s network up to date to solve the shared-bandwidth problem? Since the office has 10 workstations connected to a 10 Mbps hub, each computer average bandwidth is 1 Mbps. Since the LAN is relatively small, you can change it to a 100 MB switch. Even if their NICs are only 10 MB, they can upgrade their NICs as need be. Since seem to transfer large files often, so this will allow for the transfers to go smoothly and not bog down the network. Effectively the transfer rate is 200 Mbps depending on what their NICs are capable of. * What topology and which type of device can be used in the manufacturing area to solve the cabling difficulties? The type of topology that would be used is an extended star network, since it will be connected to the office, which uses a star network topology. The device that would be used to overcome the cabling difficulties would be a Wireless Access Point, using a wireless router. We would need to buy Wireless NICs for each of the computers in the manufacturing areas. In case 3-1 the type of network it would be, is a client based model. It is a client based model since there is no centralized server. Old-Tech’s computers transfer large amounts of files to each other on the network. Since any of the users can share their resources on their computer, each person needs determine what level of access other people have to their resources on their computer. Case 3-2 * What type...

...Computer Information Systems Paper Charles E. Jones Jr. CIS/319 Version 8 April 29, 2012 Ike Shia Abstract This paper is to focus on the accuracy, convenience, different types of storage methods, and the roles they play as far as the speed of the systems. Throughout the paper it discusses the best input and output methods for various hardware and software. Accuracy of Data Accuracy of data input is important. What method of data input would be best for each of the following situations and why: As far for printed questionnaires the best method for data input would be a keyboard, because it permits one to produce the required test that formulates the questionnaires. The best method for a telephone survey would be voice recognition and recording system because a voice input device can be programmed to distinguish and record answers spoken into the receiver allowing it to all be computed. Bank checks would best be used in a scanning method that recognizes bar codes. To be more specific a magnetic scanning input device would be the exact system to use. This system reads the numbers at the bottom of the checks and will mechanically make modifications to the correct accounts. It will input the codes in a system will magnetize the information at the bottom of the check for simple interpretation. For retail tags the best data input for would be a bar code scanner as well. This specific scanner is called an optical scanning input device. By using a bar code scanner it...

...dramatically affect students' attitudes toward learning and their habits of learning. Students need an environment that is organized, stimulating, and comfortable in order to learn effectively. One way a teacher can create this type of learning environment is by creating learning centers throughout his or her classroom along with instructional areas. Take the physical features of your classroom into account when planning out what type of learning centers you want to have in your classroom. As the year progresses, you can add different kinds of learning centers to fit your classes. When sitting up your learning centers you not only want to take in the physical features of your classroom. You also need to consider the age of your students, the number of students and the type of activities you want to be conducted. Learning centers consist of multiple stations for children to rotate through. Stations may contain activities from different subjects, such as math, science and reading, or different activities related to the same topic. Using learning centers in your classroom is a fun way for students to experience hands-on learning independently or in small groups. It also opens up possibilities for you to work with small groups or individual students. One type of learning center that is valuable for young children is a reading center. A reading center is a place for students to read independently or quietly with a partner. It should provide comfortable seating, a variety of books...

The first question discussed utilities that would be used to establish what servers were compromised. Web shells, administrative interfaces, and general attack activity were three indicators to make this determination. The second question involved identifying methodologies to find out what network equipment...
