To increase the maximum distance for a signal. If put after the maximum distance the signal may degrade. 3. The connection and processing speed. It also depends on the number of connections the computer or laptop will allow. Lab Review: 4.2 – Page: 85 1. A. Bend Radius: The minimum radius that a fiber optic cable can be bent without loss of light or impairment. A general rule that it be no less than 15 times the cable diameter B. To not affect a signal sent down the line. 2. The core/Glass Filament, Cladding, Buffer, Strengthener and Outer Jacket. Lab Review: 4.3 – Page: 90 1. Ease of installation, lack of certified fiber optic specialists and changes to the physical design of the network later on. 2. By limiting the devices needed depending on the distance and need of each network. Verify the number of access points needed before the start. Lab Review: 4.4 – Page: 95 1.

...NT1210 Lab 3 3.1.1 If wireless devices where not governed by the Wi-Fi alliance it would make it hard to communicate hardware and software between different machines. That would mean cable providers, cellphone providers, and internet providers would all have to use their own Wi-Fi frequencies. Without the WI-FI alliance it would be to hard to manage day to day life with all devices not being able to share hardware and software. Also there would be no real security so it would be easy for someone to hack all of your information. 3.1.2 A model that is used to visualize something that I would use is power points. It is easier to explain something to someone when you break down the information into slides and show key points. Power points make information easier to understand. 3.1.3 Data Link Physical Application Network Transport 3.1.4 If the model is to general then you wouldn’t understand it. If the model is to granular then the data would begin to overlap itself. Review.3.1 1. The data wouldn’t be filtered correctly so there would be connection errors. 2. (OSI) started in the 1970s, with a lot of progress on individual standards in the 1980s, and with vendor products appearing by the early 1990s. It was created to compete with TCP/IP.

TCP refers to Transmission Control Protocol. OSI refers to Open Systems Interconnection. Model TCP/IP is developed on points toward a model the internet. TCP/IP has 4 layers. OSI has 7 layers. TCP/IP more reliable than OSI OSI has strict boundaries; TCP/IP does not have very strict boundaries. TCP/IP follow a horizontal approach. OSI follows a vertical approach. In the application layer, TCP/IP uses both session and presentation layer. OSI uses different session and presentation layers. TCP/IP developed protocols then model. OSI developed model then protocol. TCP/IP offers support for connectionless communication within the network layer. In the network layer, OSI supports both connectionless and connection-oriented communication. TCP/IP is protocol dependent. OSI is protocol independent. http://www.differencebetween.net/technology/internet/difference-between-osi-and-tcp-ip-model/ Read more: Difference between OSI and TCP IP Model | Difference Between | Difference between OSI vs TCP IP Model http://www.differencebetween.net/technology/internet/difference-between-osi-and-tcp-ip-model/#ixzz3f4nyPzTU TCP/IP model protocols and functions.

...ip address classes and special-use ip address space IP Addresses Classes and Special-Use IP Address Space Samuel Abraham ITT Technical Institute NT2460 Mr. Taylor 6/25/2013 Class A Addresses Class A addresses are used for very large networks with millions of hosts, such as the Internet. A Class A network number uses the first 8 bits of the IP address as its network ID. The remaining 24 bits make up the host part of the IP address. The value assigned to the first byte of a Class A network number falls within the range 0 to 127. For example, consider the IP address 75.4.10.4. The value 75 in the first byte indicates that the host is on a Class A network. The remaining bytes, 4.10.4, establish the host address. An RIR assigns only the first byte of a Class A number. Use of the remaining 3 bytes is left to the discretion of the owner of the network number. Only 126 Class A networks can exist because 0 is reserved for the network, and 127 is reserved for the loopback device, leaving 1 to 126 as usable addresses. Each Class A network can accommodate up to 16,777,214 hosts. The 10.x.x.x network is reserved for use by private networks for hosts that are not connected to the Internet. If you want to assign a Class A network and you are not visible on the Internet, you can use one of these network addresses. Class B Addresses Class B addresses are used for medium-size networks, such as universities and large businesses with...

Lab 6.2 Review Its bad to have lots of wireless network around you cause it could cause lag around you it depend on the people. The standard allows having speed and it allows you to have a better connection. Lab 6.3:WLAN Router Configuration Exercise 6.3.1 It uses IP addresses because it allows to config your setting easier and it would allow you to customize your setting. Exercise 6.3.2 The router auto assigns the IP addresses when you first start using the router. It shows you how the setting gets lock but you could unlock them to change those settings. Exercise 6.3.3 The IP config show you everything you need to know from your IP address and your gateway and basically it shows you your networking.

Networking standard: Network Standards refer to a series of definitions for data & voice networks and are published by IEEE and ISO. Network standards define how networks are supposed to run in relations to architecture, electrical, interface and overall process standards. TCP/IP Model: Is maintained by the Internet Engineering Task Force (IETF). Provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. Development of the networking model was funded by DARPA, an agency of the United States Department of Defense. Open networking model: Like TCP/IP purposefully shares the details that any vendor can make products using those standards. Open Systems Interconnection (OSI) model: Uses 7 layers, with layers 1 through 4 matching layers 1 through 4 on TCP/IP’s model. Encoding: A set of rules used to represent characters or values in an alternative format. Header: Information at the beginning of a data packet. Header typically includes addressing...

...An operating system is the framework that allows you to communicate with computer hardware in an interactive way (Answers Corporation, 2013). Without this, you would not be able to tell the computer to do anything and it would not have any instructions to follow (Answers Corporation, 2013). This is why it is important for a computer to have an operating system (Answers Corporation, 2013). There are three main operating systems Windows, Mac, and Linux. When it comes to popularity and market share the most popular operating systems are Windows and Mac. Linux is an operating system that is popular with desktop users (HubPages, 2013), According to HubPages, “Windows is the Operating System with the largest market share. However, this doesn’t make it the best when it comes to quality and consistency as it is constantly marred with problems of viruses and malware (HubPages, 2013).” It usually had an affordable price tag at first, but the consumer is charges extra items like soft wear and anti-virus expenses that add up (HubPages, 2013). Linux is usually thought as a less effective than Mac and Windows, however it does offer many software programs that are similar to the Windows and Mac programs for free (HubPages, 2013). All three computer operating systems have Intel processors that make them unique. According to Pearson Certification Team, “Macintosh computers have Intel processors, they are not PCs. Likewise, the Mac OS is not compatible with PC hardware, and PC- based operating...
