Nt1210 Lab 8

    One possible source of error that can affect the results was that a mercury thermometer was used instead of an electronic one. The use of a mercury

In quadrants 1 and 2 how the amount and constituents of the fingerprint residue on the substrate affects the fingerprint image, is determined. In quadrant 1, excess sebum and moisture is first removed from the finger tips with the help of a clean cloth. In quadrant 2, fingertip is first wiped around the nose or forehead to create excess sebum. Quadrant 3 and 4 were used to compare the details between untreated and dusted fingerprint residues.

7.1 What is the relationship between the bandwidth of a signal before and after it at has been encoded using spread spectrum?

The objectives of this lab were to install essential services such as Active Directory, Dynamic Host Configuration Service, Domain Name Service and Network Time Service on a Windows Server Platform. I used windows server 2016 technical review version 3 and successfully installed all the mentioned services on it. In this lab we used all services on windows as primary and I configured the services on Linux as secondary services.

Tor: “Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy.

We found the density of the unknown object #6 to be 5.9(g/mL). We then use the table to identify the metal, and the result is that the name of the metal is zinc. Since the density of zinc is 7.14 and that is the closes number to our density, we determine that our unknown object is zinc. Our average density for the unknown liquid #5 is .779(g/mL). The closes density of a known liquid on the table is .792(g/mL), so we concluded that our liquid #5 is cyclohexane which has a density of

Lab Three repeats much of Lab Two by setting up the same core services, DNS and DHCP, but adds Microsoft’s Active Directory role to the server. The lab introduces the student to administrating these services in a Graphical based, Windows environment.

Full Backups: A full backup is a complete backup of everything. Sometimes referred to as a normal backup. This normally takes the longest time to perform (and is typically the largest option).

This lab provided a virtual environment that simulated a corporate WAN network. Having a similar network environment at the organization I am currently employed at, I have some experience with vulnerability scanning. I do not have much experience using the nmap utility however, so I was interested to get some experience by completing the tasks within this lab. I didn’t experience many challenges following the steps in the lab itself. I was able to launch the environment successfully and perform the steps without any issue. As with any new environment, it took me a little time to figure out the layout of the simulation and how it functioned. After reading the documentation and spending about ten minutes clicking through the different areas, I felt comfortable and began the steps of the lab.

High temperatures are caused by fires. Fire is the most hazardous physical threat to a system. This is due to the toxic frames that are generated by fire and the water that is used in fire suppression. High temperatures melt Computer resources hence damaging them. Hard disks melt at temperatures exceeding 150 degrees Fahrenheit, optical media and paper products melt when temperatures reach the excess of 100 and 350 degrees Fahrenheit respectively. Extensive exposure to humid conditions damages the electrical and electronic components. The condensed water causes short circuits in mother boards and affects optical and magnetic media adversely.

The theoretical E° of the Cu-Pb voltaic cell was calculated by using the equation E°cell = E°cathode - E°anode. The cathode in part A was copper, while the anode was lead. The E° of copper, was 0.34V, and the E° of lead was -0.13V, and subtracting the E° of lead from the E° of copper resulted in the theoretical E°cell value of 0.47V. The average corrected E°cell for the Cu-Pb voltaic cell was found to be 0.492V, which is quite close to the theoretical value of 0.47V. The average corrected E°were recorded in the following table:

I did not change any parts of the circuit (wires, ammeter, voltmeter or battery pack) in between the measurements – this would have prevented small discrepancies between circuit components from affecting the results. When taking the measurements from the voltmeter and ammeter, I waited for the reading to settle completely. If it didn’t settle, then I would have made an estimate of the middle value being shown. Waiting for the reading to settle prevented accidentally taking a reading while the value is fluctuating randomly when the power is first turned

Electrical circuit analysis is done in order to allow the designer to verify his design and to predict the response of the system under varying conditions of load and excitation.

For each resistor/capacitor pair, times required to achieve 63.2 percent of maximum voltage change and 86.5 percent of maximum voltage change were recorded.
