...Study Guide: Lesson 4 A Little Logic Lesson Overview Logic is the primary tool or methodology in studying philosophy. Philosophy is about analyzing and constructing arguments and a good understanding of the basics of logical reasoning is essential in performing that task. The next 3 lessons will focus on logic and analyzing arguments. In this lesson, you will first be introduced to the laws of logic. These are the first principles for all reasoning. We will then discuss the specialized terminology we use in logic. Finally, we will examine 2 major kinds of logical reasoning: deductive and inductive. We will consider different forms of arguments under each and discuss how to evaluate these arguments. Take note that a large part of this lesson is about learning the terminology for logic. Tasks Read and take notes from chapter 5 of Philosophy: Critically Thinking about Foundational Beliefs, “A Little Logic.” As you read, make sure you understand the following points and questions: * Why are the laws of logic foundational? * The Law of Logic makes discourse possible. If they are not recognized as true, than nothing we claim makes any sense. Therefore, it is important to have a firm grasp of these laws. * List and explain the 3 laws of logic. 1. Noncontradiction – “Something cannot both be and not be at the same time and in the same respect. Expressed symbolically: ~ (P•~P).² It reads, “It is not the case that there can be both P and non-P”. 2....

Nt1110 Unit 4 Assignment Video Summary

...Deborah Collins NT110 – Prof Whitehead Unit 4. Assignment Video 04/14/14 Motherboards come in several form-factors. When building a system, it is important to know what it will be used for before purchasing. Two of the most important parts need to be considered before the system is built – the CPU and the motherboard. There are several different types of CPUs and motherboards, so care should be taken that the CPU can be seated on the motherboard. Also, think about what the computer will be used for. General users will not need a top of the line system for browsing the web, email, social networking and word processing types applications, so a “bare-bones” type of computer may be a better selection. Systems used for gaming, video editing or high end graphics will need to have other considerations such as a higher end graphics card, more RAM and better than average cooling.

...NT1110 Unit 4 Research Paper Student NT1110 Abstract Components and technology of today’s computer motherboards. This paper will give a brief description of chipsets, Motherboard bus’s, & Component Integration. NT1110 Unit 4 Research Paper The chipset on today’s computers is responsible for managing the flow of information between the CPU, Memory, & the Peripherals. Chipsets are usually deigned to work with a specific family of microprocessor such as Intel or AMD. Mother board Buses can be broken down into two different types, the first type is the internal bus. The internal bus is easily recognized by the gold lines of wire that run throughout the motherboard. The external buses are the slots filled with pins on the motherboard. Both types of bus are basically the lines of communication for the mother boar. There are six major types of external buses on a common motherboard, only a few of these are found on the mother board of a home PC, they are PCI, AGP, USB, & IDE. The external Buses connect to the Internal bus via the pins in there Appropriate slots, those pins transfer the information from the external buses to the internal bus and then to the final destination. The final topic of this paper is component Integration, component integration has eliminated the need for individual component hard ware and the heat they produce. The elimination of those two things has enabled the manufacturers to reduce the size of today’s computers enabling the......

Unit 4 Chap 15 Case Study

...Unit 4 Chapter 15 Case Study 1. McDonalds has taken a proactive approach toward supporting and valuing diversity by establishing an initial diversity program. In 1980 they hired their first official manager for the program. McDonalds has always embraced and empowered a diverse workforce. Encouraging diversity both at McDonalds and within its supply chain is not only the right thing to do but good for business. 2. There are a couple different structures and systems that McDonalds has established in order to ensure that it leverages its diversity as part of its business strategy. One critical component to diversity and inclusion for McDonald's is teaching people how to work with others who are different than themselves. The core of its education framework includes formal presentations, workshops, seminars, and informal training designed to practice the skills and behaviors needed to collaborate with and lead people in an inclusive, diverse workforce. 3. McDonalds plans to overcome prejudice and discrimination by having all of its different human networks in a U.S. headquarters. 4. The AFA and AFTAH are sick and tired of rewarding and subsidizing corporations that promote homosexuality. McDonalds should take a step back on having so many homosexual employees in order for the AFA and AFTAH to associate with them . 5.
