HIGH SPEED SWITCHES
PRELIMINARY DATA

DESCRIPTION The 2N2219A and 2N2222A are silicon Planar Epitaxial NPN transistors in Jedec TO-39 (for 2N2219A) and in Jedec TO-18 (for 2N2222A) metal case. They are designed for high speed switching application at collector current up to 500mA, and feature useful current gain over a wide range of collector current, low leakage currents and low saturation voltage.

ARP is used to mediate between Ethernet (and other broadcast link-level protocols) and the network layer, or IP protocols. Put more simply, ARP converts IP addresses to Ethernet addresses. 2. What is the purpose of the dynamic host control protocol (DHCP)? DHCP (Dynamic Host Configuration Protocol) is a communications protocol that lets network administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network. http://searchunifiedcommunications.techtarget.com/definition/DHCP/ARP. Lab #2 Network Documentation 1. When you TELNET to LAN Switch 1 and LAN Switch 2, why is it a good idea to first PING an IP interface or port’s IP address? The ping verifies connectivity by sending ICMP echo packets to a host and listening for an echo reply. This will detect if there are any name resolution issues. 2. Why is using Telnet a security risk for an IP network infrastructure? Telnet sessions are in clear text and programs such as packet sniff can capture passwords and then use them to log into those sessions. 3. How can you mitigate the security risk caused by Telnet? Intrusion detection is a packet inspection tool that monitors, intercepts and responds to abuse in real time.

The first control was a negative control, Water ,this would show there is no Amylase present. The second control would be a Positive control ,the starch solution this would show the presence of the enzyme amylase. The negative control water does not contain starch. Saliva contains Amylase this is why it is included in the experiment. The saliva is a positive because it turned yellow, this shows no starch left because the amylase broke it all down. 2. What is the function of amylase? What does amylase do to starch? The function of amylase is to start the digestion proses. Amylase function is to break down starch to sugar. 3. Which of the foods that you tested contained amylase? Which did not? What experimental evidence supports your claim? The cooked rice contained Amylase and the starch solution contained amylase. The water the Apple contained no starch. 4. Saliva does not contain amylase until babies are two months old. How could this affect an infant’s digestive requirements? Usual babies do not start eating food until three months. The reason there saliva does not contain amylase is because there bodies have not started producing it yet. For there digestion it means they will not break down any starch foods and just pass them trough there body...

...Lab Report 1: Pipettes and Std Curve Ingrid Simons University of Texas at El Paso June 12, 2014 Introduction: Procedures that require very small volumes of DNA and reagents are performed with instruments such as, micropipettes and pipettes. These instruments are used when scientists need to accurately and precisely deliver small volumes of a liquid. Molecular biologists use very small volumes of liquid at times they are as small as 0.1 µL, in order to do these measurements the use micropipettes. The function of the micropipettes is to act as a plunger when the depressed by the thumb and by its release liquid is drawn into a disposable plastic tip. The liquid is released when the plunger is pressed again (The University of QueensLand). The tip is an important part of the micropipette, each tip is disposable and come in different sizes depending of the micropipette being used. There is three standard micropipettes, the P20 which measures 0.5-20μL, P200 that measures 20-200 μL, and P1000 that measures 100 μL to 1 mL. An important part of this laboratory was learning how to read the meniscus curve. A meniscus is a curve that is formed at the surface of a molecular substance, such as water, when it touches another material (USGS). Meniscus is caused by adhesion, a result of water’s high surface tension. The glass beaker attracts water molecules, and water molecules stay together, as a result many molecules gather to touch the glass. They will accumulate along the...
