...Networking Kaplan University October 23, 2012 IT-331 Prof: Scott Paetzold There are endless amount of networking sites available online that any individual can join in hopes to gain opportunities and maintain their career goals. These sites can differ heavily in popularity and focus; most are free but there are many that charge annual fees to join. The choice in whether or not to join a free site or pay site depends heavily on the individual and what he/she is looking to achieve. The free sites offer many benefits that are appealing to a lot of people but the sites with fees offer much more information and learning opportunities. The fee-based sites have many advantages that free sites cannot offer. These sites offer a wide range of benefits and opportunities that any member can take advantage of. Though it costs to join these sites, the membership fee is often very low compared to the amount of benefits that are offered. Additionally, these benefits are much more focused on one area of interest (such as IT), giving the user much more information than most free sites can offer. These fees-based sites offer professional trends, conferences, publications, job listings, product discounts, mentoring, and most even have an interactive learning center to help build your knowledge in your career focus area (Denham, 2011). There are also many networking sites that can be joined for free that are very popular and useful. One such site is LinkedIn. This site has become...

...Networking Carol Ridgeway Kaplan University IT331 Technology Infrastructure Professor Howard Weinraub Unit 3 Assignment May 7, 2013 Twisted Pair Cables is a pair of wires that are twisted together to provide protection against crosstalk and noise that is generated by the adjacent pairs that forms a circuit to can transmit data. There are two basic types of twisted-pair cables, unshielded twisted pair, UTP, and shielded twisted pair, STP (Cisco, 2003). Coaxial Cables have a hollow outer cylindrical conductor that is surrounded by a single inner wire that is made of two conducting elements, copper and a copper braid or metallic foil. The copper conductor is surrounded by a layer of flexible insulation that has a woven copper braid, or metallic foil, that helps to reduce the amount of outside interference. And finally, a cable jacket covers the shield (Cisco, 2003). A fiber optic cable contains strands of glass fibers that is inside of an insulated casing that is designed for long distance and very high bandwidth, gigabit speed, network communications by using pulse of light to carry a signal (Scocco, 2006). Wireless signals are electromagnetic waves that travels through the air. To receive the signals from the access point the computer, or laptop, must have a wireless adapter card, or wireless NIC, installed. Wireless signals use portions of the RF spectrum to transmit voice, video, and data. Satellite radio provides uninterrupted services to millions...

...Unit 2: Components of IT Kaplan University IT331 –01 Contents Questions 3 References 7 Questions 1) Describe at least three different networks (computer or data communications) which you access or interact with on an average day. I use a variety of networks on a daily basis during the work week. To start, I work from home and I must first connect to my home LAN which has an internet connection. My home LAN consists of a router that shares my internet connection wirelessly. Next, I connect to my work’s LAN by using a Virtual Private Network (VPN). My work’s LAN consists of a router and several switches. On the network, there are several workstations, servers, printers, and various resources that I access to perform my job tasks. The VPN connection is also handled by a specific router for VPN access. In addition to my home network, work network, and VPN, I also have a cloud-based music service where I access my music that gets me through the day. The cloud based network is not local, but it is accessible over the internet at Google. 2) Binary data codes like EBCDIC, ASCII, or Unicode are often presented using hexadecimal notation rather than a long list of 0’s and 1’s. Likewise other items requiring long sequences of 0’s and 1’s like IP addresses to identify network location are generally presented in non-binary formats as well. Describe the relationship between a hexadecimal character and its associated binary. Describe the relationship between one octet...

...IT331-CNS Capstone 6/28/12 OSI Model 1. Explain in detail the functions of each layer of the 7-layer OSI model. a. Layer 1 – Physical Layer – To establish and terminate the connection to a media source, it also does the conversions of data from one form to another. b. Layer 2 – Data-Link Layer – Transmits data from one point to another. c. Layer 3 – Network Layer – Transmits data from one host to another on another network. d. Layer 4 – Transport Layer – Controls the end-to-end connections, reliability, flow control of data in a network. e. Layer 5 – Session Layer – Controls connections between computers and manages application sessions in a network. f. Layer 6 – Presentation layer – This layer controls data representation and the encryption and decryption of data in a network. g. Layer 7 – Application Layer – This layer interacts with software applications that implement a communicating component. The application layer decides whether sufficient network or the requested communication exists. 2. Using the OSI model as a reference, describe how you would troubleshoot connectivity problems. h. To troubleshoot connectivity problems using the OSI model you should answer the following questions: i. Is your network cable plugged in? ii. Is there a link light on the Ethernet switch and Ethernet NIC? iii. Do you have an IP address? iv. Can you ping your default gateway? ...
