Support your answer with an appropriate screenshot. (3) MAC address, also called the Physical Address in the command prompt, is 84:3A:4B:79:26:c4 2. Communication & Networking a. List technical steps required for setting up a wireless network in a home-setting (4) 1. Equipment Needed: Internet Connection (in this example internet is provide via Satellite connection) with SAT Cable, Modem with power supply, Wireless router (in this example the router is a N300 Wireless Router) with power supply, Ethernet Cable. Each set up may vary slightly dependent on equipment being used. 2. Start with all equipment off. 3. Connect one end of the Ethernet cable to the modem and the other end to the internet port on the router. It is now common that most modems and routers have these ports labeled. 4. Plug in and turn on the modem. If your modem has a battery backup, first remove and reinsert the battery before connecting the modem to the power. 5. 6. 7. 8. 9. It is recommended to wait approximately 2 minutes until the modem is fully turned on. Connect the power adapter to the router, then plug it into the power outlet. Make sure the Power On/Off button is in the ON position (pushed in). Wait until the wireless LED turns solid green. Connect the router to a computer. It is common that the computer will identify the new network connection and ask if a connection is desired. Follow the prompts selecting the Network Name (for this example it is NETGEAR) and the Network Password. The Network Name is also the Service Set Identifier or SSID. If not prompted then a manual setup is possible. Connect wirelessly by going to a utility software that manages wireless connections on the computer. Look for the preset NETGEAR wireless network name and select it. Enter the password. Click Connect. Open a browser. b. List the key differences between 1. Ring and Star topologies (4) i Configuration of networks – RING topology – connects all devices to each other. STAR topology - has a central connection point. All devices hang off one device. ii Amount of cabling (dependent) – Initially RING topologies required less cabling then STAR topologies. Now with wireless connectivity option the amount of cabling used in a STAR topologies can be greatly reduced. iii Effects of device dropping off the network – RING topology – if one device falls off the network then the entire network goes down. STAR topology – if one device falls off the network then only that device is affected. 2. PAN and WAN (4) i Geographical scope – PAN is a Personal Area Network and typically has a reach of about 30 feet or 10 meters. A WAN is a Wide Area Network and typically covers a large geographical area. For example the internet is the world’s largest wide area network. ii Size – PAN is typically one network. WAN typically consists of several smaller networks, which may use different computer platforms and network technologies. 3. Client-server and Peer-to-peer networks (4) i Network Configuration – In a CLIENT-SERVER network a server is present. In a PEER-TO-PEER network there is no server. 4. Coaxial cable and Fiber optic cable (4) i Method of Transfer – COAXIAL CABLE – Digital information is transferred via an electromagnetic wave. In FIBER OPTIC CABLE – Digital information is transferred via light and glass. ii Speed – FIBER OPTIC CABLE has a greater bandwidth than COAXIAL CABLE. iii Cable Sensitivity – COAXIAL CABLE bend better. FIBER OPTIC CABLE can cut out or distort if bend is great or cable gets twisted or kinked. . 3. Website Design a. Design and develop a Website of your own based on a specific theme, using the space provided by the University of Tennessee. (10) a This website uses the Urban color scheme and the Tabs website template. They cover aspects of information currently not covered on the SCPLS website. These pages cover the Geek the Library Campaign, Affordable Care Act, SCPLS Wishlist, Partner Spotlight. Two of these pages are creating awareness of the role of the library system within the community. One page provides information on a national scheme for healthcare insurance and the other lets the community know of another way it can contribute to the success of programming. The System Director has agreed that these pages will be added to the Sevier County Public Library System once converted into wordpress. b. Using Unix account provided by the UT, upload content / material / information that you think is relevant to the theme of your Website. (10) Submit the link of your Website as part of your answer. ABrueland Unix Website 4. Database Basics a. List the key differences between spreadsheet and databases (4) (Joan 2010) i. Difference in Use – Spreadsheets are typically applications for tabulating data, generating reports or charts; while databases are for the large storage of data that will be retrieved by users. ii. Amount of Data – Spreadsheets in comparison to databases handle a smaller amount of data. iii. Difference in way data is edited & accessed – Spreadsheets are applications, while databases are collections of related data that require an application to access and manipulate the data. iv. Entry of data – In spreadsheets the data is typically entered in by people. In databases the data is typically entered or modified via an application. b. Explain the application of databases for Dashboards (4) i. Dashboards are user interfaces that present information such as key performance indicators. They are the interfaces that is part of OLAP (online analytical processing), which is a system consisting of computer hardware, database software, and analytical tools that are optimized for analyzing and manipulating data. c. Explain the key features of the following types of databases: i. Hierarchical (2) – Allows for one-to-one and one-to-many relationships linked in a hierarchical or tree structure. Parent to child or Parent to many children. (Database Models n.d.) ii. Networked (2) – Allows for one-to-one and one-to-many as well as many-to-many relationships. Parent to child, Parent to many children, more than one Parent per child (Database Models n.d.) iii. Relational (2) – Relationships are specified by joining common data stored in the fields of records in different tables. The way a relational database establishes relationships allows the tale to be essentially independent, but the tables can be joined for a particular task. Relationships can be added, changed, deleted on demand making this database model very flexible. (book) d. Illustrate the following relationships i. One-to-One relationship (2) – Parent Child ii. One-to-Many relationship (2) – Parent Child Child Child iii. Many-to-Many relationship (2) – Parent Parent Child Child Child Child 5. Entity-relationship Diagram a. Identify and list entities in the following E-R diagram (4) ENTITIES – Some identifiable object relevant to the system being built. 1. Customer 2. Order b. Identify and list attributes in the following E-R diagram (4) ATTRIBUTES – A characteristic of an Entity. 1. Customer ID 2. Name 3. Address 4. City_State_Zip 5. Discount 6. Order Number 7. Order Date 8. Promised Date c. Identify and list relationship and cardinality of relationship in the following E-R diagram (4) CARDINALITY OF ONE-TO-ONE 1. Customer to Customer ID 2. Customer to Name 3. Customer to Address 4. Customer to City_State_Zip 5. Customer to Discount 6. Order to Order Number 7. Order to Order Date 8. Order to Promised Date CARDINALITY OF ONE-TO-MANY 1. Customer to Order d. Identify primary keys in the following E-R diagram (4) PRIMARY KEYS 1. Customer ID 2. Order Number e. Tabularize the following E-R diagram (4) - I have been unsuccessful in getting the one-to-many to display. Access says it is there but the infinite sign does not display. It needs to show that one customer can place many orders. References CENGAGE Learning. "Information Systems Analysis and Design."
