1. Compare the hash values calculated for example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. They change to keep authentication and integrity. 2. Why are the MD5sum and SHA1sum hash values the same every time you calculate for the “example.txt” sample fi le? What if they were different when you re-calculated the hash value at the other end? These are the same to verify authentication and integrity.

Lab 18 Troubleshooting Windows 7 Exercise 18.1 Troubleshooting Network ConnectivityOverview Rob calls the help desk to report that he cannot access any websites on the Internet. While he is still on the phone‚ you have him try to access a file on his departmental server. In both cases‚ his attempts fail. Troubleshoot Rob’s computer and determine why he is unable to access the network. The troubleshooting process will be completed when you are able to access the network using Rob’s computer

Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Throughout this lab‚ data was collected and compiled to analyze these effects across selectively

GS104 Lab Report Experiment # 2 Data Collection David Case: January 23‚ 2015 Experiment #2 Data Collection Objectives: Exercise 1: Formulating a Hypothesis about pitching speed. To form a hypothesis for the pitching velocity of a ball. Use a spreadsheet and math to calculate the actual velocity and determine the accuracy of the hypothesis. I will also roll a large ball to measure its velocity and graph its horizontal motion. Materials: Volley

soil from the site and then take several other samples from different points on the site. This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests. In order to turn my soil samples

Balance Lab of a Copper Slug and Sodium Chloride (NaCl) on a Centigram and Electronic Scale PURPOSE/INTRODUCTION The purpose of this experiment is to learn how to weigh a substance on a centigram scale and an electronic scale through direct weight or by weight difference. The hypothesis is that all scales used should show the same weight for a given sample. The experiment should show precision and accuracy of the equipment being used. This will allow a better understanding on how to properly
