Questions for the DC Motor Procedures: 1. What is a use of an Optical Isolator (Optoisolator)? An Optical Isolator is a type of semiconductor that allows signals to transfer between circuits and systems, while isolating those systems from each other; they are mainly use for monitoring systems. 2. Use Ohmmeter to measure resistance for DC motor used in this Lab. 56 omhs 3. In Activity 1, explain how you turned the DC motor “on” and “off.” I tried using a transistor as switch using a breadboard and a power supply (battery) to power the motor, with a 1k ohms resistor to limit current, I also connected a custom power supply to add 3.3v onto the breadboard. On our project the simplest way is the ON-OFF switch with is used to control the switch to only rotate at the maximum speed of rotation only in one direction, to make...

...Week 1 Lab Part 1 - Assessment Worksheet Assess the Impact on Access Controls for a Regulatory Case Study Overview Watch the Demo Lab in the Week 1 Learning Space Unit 1, and answer the questions below. The lab demonstrates creating an Active Directory domain as well as user and group objects within the new domain. Directories will be created and permissions assigned based on the required access control as defined in the matrix. Group Policy Objects will also be created and linked to Objects within the domain to enforce security settings. Lab Assessment Questions & Answers 1. What does DACL stand for and what does it mean? Discretionary access control List (DACL) is a type of access control defined by the Trusted Computer System Evaluation Criteria "as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong 2. Why would you add permissions to a group instead of the individual? It is more resourceful and less time consuming. 3. List at least 3 different types of access control permissions available in Windows. Full Control, Modify, Execute, Read, Write 4. What are the least permissions that you need in order to view the contents of a folder? Read, so the user has access to any file on the system that they are entitled to, but they are not able to make any changes. 5. What are other available Password Policy options that could be enforce to improve security? ...

Include an overview of the major tasks accomplished in this lab and any difficulties you encountered in the completion of this lab assignment. Installing the Fedora 13 seemed easy enough but did take a long time when it came to the part of loading everything. I followed the lab instruction that helped me accomplished this which wasn’t too bad to follow. I did wish it had the explanation of each step like the other labs because it helped me understand what I’m doing and given the reason I never dealt with Linux before. The overview of the whole installation started with the “disc” and running it, then from the initial I was able to customize a few things (language, date and time, storage drive, own password, partition, software package, etc.). Luckily I did not encounter any problem that I was not able to install it but instead it went smooth. Something I did notice different was the appearance and where the taskbar was located.

...Spread Spectrum Transmission Comparison Introduction to Spread Spectrum Transmission • What is it? Why is it important? What issues are addressed? How does it work? It is the practice of spreading the transmitted signal to occupy the frequency spectrum available for transmission. The advantages of spectrum spreading include noise reduction, security and resistance to jamming and interception. It’s important because in the next several years anyone will escape being involved, in some way. The applications for spectrum range are, from Wireless Lan’s, radio modem devices for warehousing, palmtop devices to digital dispatch and cellular communication etc. the issues will in a constant frequency signal is easy to intercept, and can have catastrophic interference. Spread spectrum uses wideband, noise-like signals that are hard to detect, intercept, or demodulate. Additionally, spread-spectrum signals are harder to jam than narrow band signals. Frequency Hopping Spread Spectrum (FHSS) • What is it? How does it work? What issues are addressed? Why is it important? Is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. FHSS radio systems work by constantly hopping between a number of frequencies, With FHSS, a short burst is transmitted at one frequency, followed by a short burst transmitted at another frequency, and so on, until the entire transmission is completed...

...Introduction The Department of Defense (DOD) has several departments within the agency that companies will need to work with in order to carry out the terms of their contracts. When considering technology specifically, the DOD has the following departments ready to assist companies: Information Assurance Support Environment, Defense Information Systems Agency, Defense Technology Security Administration, Defense Cyber Crime Center, Defense Technical Information Center, and possibly others that were not immediately obvious (U.S. Department of Defense, 2015). The Information Assurance Support Environment produces Security Technical Implementation Guides (STIGs) for various computer topics, which can be utilized by companies who wish to do business with the DOD. These guides serve as a baseline for the company in regards to the technology specifications they should have in place in order to lock down their systems and network to make them less vulnerable to malicious attacks (Defense Information Systems Agency, 2015). Among these STIGs is one written specifically for the Windows 8 / 8.1 operating system (Information Assurance Support Environment, 2015). This STIG outlines some of the changes made by Microsoft to Windows 8 / 8.1 as well as their recommendations for securing computers, which use that operating system. Tools Windows 8 / 8.1 comes with many tools built into it that allow for the administrator to use in order to do a security audit. A keyboard shortcut of pressing...

First, they provide a lot of food for the global food supply. Second, it provides the world with a lot of medicines. The forest has many plants the hay chemicals in them used to treat diseases like malaria and diabetes. Next, wood is extracted from the forest for the world. Many of the world’s nice timber types like teak and mahogany used in furniture and building are from the rainforest. Furthermore, the rain forests provide the world clothes. The forest has a lot of plants in it that are used in the clothing industry. Finally, the rain forest is home to millions of wildlife. Question 2 With clear examples, discuss 5 major causes of deforestation. There are many causes of deforestation. First, the increasing need for cattle and other animals. The land is needed for grazing for livestock used to provide meat for the world. Second, agriculture moves into the area. Small and big businesses are moving into the forest areas for the fertile soil to produce vital plants and vegetables. Thirdly, the logging industry is a big part of the deforestation. The logging industry is trying to keep up with the world demand for timber. Next, fires have been destroying them.
