Layer 2 Domains Paper Layer 2 Domains Paper We have chosen an extended star topology connection using a router to designate the VLANS and two 24 port switches to provide the most cost effective setup for this small office network. Being the very small nature of the setup we are using a class C network of 192.168.0.1 that we will designate the first 20 IP addresses of each VLAN as static to support any servers we might install as well as printers we may install in the future.

PDUs typically include “envelope information” in the form of specific headers and trailers. __F__ 5. The Session layer is equipped to request retransmission of all erroneous or missing PDUs when reassembly is underway‚ so that it can guarantee reliable delivery of data from sender to receiver.

As a result it is frequently referred to as the OSI Seven Layer Model. A layer is a collection of theoretically similar functions that provide services to the layer directly above it and obtains service from the layer beneath it. On each single layer an instance provides services to the instances at the layer above and requests service from the layer beneath. An example of this

Experiment #1: Thin-Layer Chromatographic Analysis of Drug Components | Performed on: Wednesday‚ May 8th‚ 2013 | | | 5/15/2013 | | Introduction: The goal of this experiment was to identify an unknown analgesic drug through the use of thin-layer chromatography. The drugs used were‚ Unknown #1‚ caffeine‚ aspirin‚ and acetaminophen. Thin-Layer Chromatography is a technique for identifying substances using a mobile phase (developing solvent) that draws up through a

The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done on a plate that is coated with a layer of absorbent

Thin-Layer Chromatography of Analgesics Abstract: In this experiment thin-layer chromatography (TLC) was used to determine the composition of an unknown mixture of analgesics given five references of AC‚ ASP‚ CAF‚ IBU‚ SAL‚ an unknown consisting of a mixture of three of the references‚ and two unknowns (6‚23) containing a single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two
