ITNW 1425 – Chapter 1 Homework
Case Project 1-2
Question: Would you choose a peer-to-peer network or server-based network? Write a list of supplies you might purchase to accomplish this task. What computer configuration tasks might you need to perform?
ANS: In this situation I would choose a peer-to-peer network as it would fit perfectly for the six employees who still use floppy disks to get files from one computer to another. They’d each have control of resources for their own machines, training the employees on the new configuration would be minimal and inexpensive for the company and allow each employee to share files through the network. The peer-to-peer network or workgroup impose no centralized control or security over shared resources. Also the loss of a single machine means only the loss of access to the resources on that one machine, the others would continue to function. Any user can share resources on his or her computer with any other user’s computer, and each user can determine what level of access other users have to his or her shared resources. Each user in this group must act as the administrator of his or her computer’s resources. Each user would also have to remember each set of credentials, which can be confusing if they aren’t trained properly in creating secure passwords, which is where efficient training on my part to help them to understand how to create secure passwords, why they’re created and the consequences of not using them properly. Because the company wants to spend as little money as possible the challenge with security will be a huge task. The key is training the personnel on security measures and making sure they understand the consequences of their actions for the company if they choose not to follow them. Ensuring they also know and understand why they need to back up their work and data on a regular basis, install patches as needed and how it helps to keep their computer running as efficiently as possible. I’d of course recommend they purchase new computer systems (desktop PC’s) for the company, running Windows 7 or Vista. Depending on their printers I recommend they get one or two of those as well. They’d need new cables and once the PC’s are set up and mapped to the printers then the employees can begin training on them immediately. They’d need to know how to back up their data, ensure patches were installed as needed, password security. Of course each computer would have a restore CD made before training could begin. Once training is completed which shouldn’t take long at all, they’re ready to roll.
Case Project 1-3
Question: What type of network is called for --- LAN, WAN, MAN, or internetwork? What additional devices might be needed to ensure efficient network communication?
LAN - Types of network which calls for a LAN would be a smaller network, such as a school limited to a single collection of machines and connected by one or more interconnecting devices in a small geographic area. Additional devices that might be needed to ensure efficient network communication would be a hub or a switch, router. LANs are normally used for local access.
WANS – When a network’s scope expands to encompass LANs in geographically dispersed locations, they are classified as WANs because they span distances measured in miles and link two or more separate LANs. WANs user the services of third-party communication provides, such as phone companies to carry network traffic from one location to another. WANs are used in geographically dispersed locations normally used for access to remote sites elsewhere in the country or around the world.
MANS – Use WAN technologies to interconnect LANs in a specific geographic region, such as a country or city. Normally used for regional or citywide access. MANs are geographically dispersed internetworks. Uses third party communication providers to provide connectivity between locations.
Internetworks – A networked collection of LANs tied together by devices such as routers.
To ensure efficient communications each of these would in this day and age use hubs which are now Stone Age in my opinion. Switches were also used, but now the norm would be routers for communication between the different systems.

...of instruments she had were drums, the triangle, maracas, small cymbals, and rain sticks. After they all had an instrument she had them all start playing the instruments for about a minute and then she had them change instruments with another kid in the class. It got a little crazy but they all looked like they were having a good time. After the all got to play two instruments she had all the kids put the instruments back where they are suppose to go then back to the circle. When they got back to the circle the teacher went on the smart board that they have and she pulled up a bunch of songs that they could sing and dance along too. Some of the songs she pulled up were “Head Shoulders Knees and Toes”, “Twinkle Twinkle Little Star” and “The Itsy Bitsy Spider”. For each one of those songs that she would sing with the kids she would have hand movements so they would sit still. The kids were very involved in what they were told to do. The part of the music lesson they loved the most was when they were singing the songs and doing the hand motions along with the song. They looked like they were very interested in it. The teacher had all the kids doing everything as I said when they were playing the instruments everyone got an instrument and started playing and when they...

Child Development Observation

...Amber Jeppesen Child 68 MW 4:45-6:10pm October 17th, 2014 Part 1—General Information The name of the center I observed at was C.L.O.U.D.S Preschool Program at Perdew Elementary School. The address of the center: 13051 Miller Ave. Etiwanda, CA 91739. The C.L.O.U.D.S Preschool Program has goals for each and every one of its students to succeed in language development, social skills and preacademic training sets. This program does include fees, each different for every student due to the fact that each student has a different learning plan. Students come at different days as well as times. Mrs. Jones and Mrs. Jarvis were the teachers in the C.L.O.U.D.S Preschool class I observed. Mrs. Jones and Mrs. Jarvis work together teaching side by sided. Mrs. Jones is in charge of the A.M. class, while Mrs. Jarvis takes charge of the P.M. class. They offer each other assistance while the other is in charge, making it very convenient for one another. Other adults that were helping out in the classroom were Instructional Aides, hired by the Etiwanda School District that Perdew Elementary School is under. There are two aides, D’Ann and Julie. Mrs. Jones let me know there is always a parent volunteer in class with the preschoolers. Of the three days I was there observing, there were three different parent volunteers. The Instructional Aides were hands on with the kids, while the parents sat back and helped out with projects the teachers needed help with. The kid I observed...
