Lab No. 2: The Microscope Light microscopy The bright field microscope is best known to students and is most likely to be found in a classroom. Visible light is focused through a specimen by a condenser lens‚ then is passed through two more lenses placed at both ends of a light-tight tube. The latter two lenses each magnify the image. Limitations to what can be seen in bright field microscopy are not so much related to magnification as they are to resolution‚ illumination‚ and contrast

CHAPTER 7 Q1) What does the shell ordinarily do while a command is executing? What should you do if you do not want to wait for a command to finish before running another command? A1) The shell goes to “sleep” until the command has been processed. You can run a program in the background‚ which will allow you to run more than one at a time. Q3) What is a PID number? Why are these numbers useful when you run process in the background? Which utility displays the PID numbers of the commands

I took the skin-tone IAT and my data suggested a strong automatic preference for light skin compared to dark skin. I knew that I may or may not have agreed with some parts of the test results; however‚ I strongly disagree with the results that I actually did receive. The way that the test switches the sides in which the categories are populate‚ was really confusing. I do not believe that it was because there were light skinned people on one side and dark skinned people on the other‚ I believe it

The second intelligence was the logical-mathematical intelligence which represented the ability to solve mathematical and logical problems with ease. An interesting observation made by Lynn Helding states that: “the connection between logical-mathematical intelligence and musical intelligence is notable.” The reason this particular statement amaze me was because I obtain hundred scores in those two intelligences‚ and at first I thought it was a coincidence. The third intelligence was spatial intelligence

Physical Networking (NT1310) Unit 5/Activity 1 Wired and Wireless: Wired networking has traditionally been deployed for stationary computers and machines which do not require mobility. Wireless networking allows the user to roam wire free where the wireless network exists while never dropping the connection to the network. Traditionally‚ wired connections have been the primary means of access to the network‚ with wireless connectivity offering a secondary means of connection for mobile devices. Wired

Although Zigbee implements a wide assortment of security measures‚ there are still a variety of vulnerabilities and attack methods that can be used. These attacks and how they can be carried out will be described in this Section. The first and possibly easiest attack to implement is the denial of service attack. These types of attacks overload the network such that service is denied to the network’s end users. In a typical wired network this is accomplished by having a huge number nodes simultaneously

Matthew Anderson NT1310 October 1‚ 2014 Unit 3 Assignment 1 “A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu‚ 2013). There are several common instances of the bus architecture‚ including one in the motherboard of most computers. Bus networks may be the simplest way to connect multiple clients even though many may have problems. When two clients want to transmit at the same time on the same bus‚ this may cause
