...Exercise # Review question #1. In one or two paragraphs, describe how the internet changed form a government research project into a technology for business users. The internet began as a way for the military to control weapons systems while under attack. In the 60’s, the U.S. Department of Defense became worried about possible effects of nuclear attack on its computing facilities. The Defense Department realized that in the future they need powerful computers for coordination and control. The Defense Department funded a research at leading universities and institute with the goal of designing a worldwide network that could remain operational even the network were sabotage by the military enemy. The researchers were determined the best solution to accomplishing their goal was to create networks that do not require a central computer control network operations. However, at the time the only network existed was a single connection between sender and receiver from the leased telephone company line. There was a concerned of risk using single connection method for connecting computers, so the researchers developed a different method in communication using multiple channels. In 1969 the Department of Defense researchers in the Advanced Research Projects Agency (ARPA) use this direct connection network model to connect four computers; one each at University of California at Los Angeles, SRI International, University of California at Santa Barbara, and the University of Utah into the...

...Adoption of Electronic Commerce Technologies by SMEs in Malaysia Sherah Kurnia, Basil Alzougool, Mazen Ali Department of Information Systems, The University of Melbourne, Australia Emails: sherahk@unimelb.edu.au balzougool@pgrad.unimelb.edu.au mali@pgrad.unimelb.edu.au Saadat M. Alhashmi School of Information Technology Monash University Email: saadat.m.alhashmi@infotech.monash.edu.my Abstract Electronic commerce (EC) offers many benefits to organizations of any size including small to medium- sized enterprises (SMEs). At this stage, there is still a need for a better understanding of the potential and relevance of EC in developing countries as well as the behaviour of SMEs towards EC adoption. Moreover, there is still a need for a holistic view of how various widely known factors at the organization, industry and national levels affect EC adoption. Therefore, this study proposes a theoretical model of EC technologies adoption by SMEs in developing countries by incorporating various readiness factors identified in the literature that may determine EC technologies adoption by SMEs in developing countries. It then explores the influence of these factors on the adoption of different EC technologies. The environmental pressure is also considered in this study. Through a survey of SMEs within the grocery industry in Malaysia as an example of a developing country, the study demonstrates how various readiness factors influence the adoption of various EC technologies differently...

...Determining Databases and Data Communications BIS 320 August 11, 2014 Determining Databases and Data Communications In the first illustration, a marketing assistant for a consumer electronics company is responsible for the task of maintaining booths for trade shows from beginning to end and must resolve any related issues that may arise. There are many things that need to be kept track of including data related to the equipment received for trade shows. Situations such as these required detailed lists of all things involved. For example, the equipment related to the trade show booth would be kept in its own category where they would be listed individually in relation to their utilization purposes for the trade show. Other data would need to be recorded such as detailed information in relation to the condition of the items during the shipping process. The marketing assistant must ensure the booth and its display contents, are brought to their desired location in a timely fashion and taken back securely in order to assure their future use to the company. By having information such as postal tracking numbers, tabs can be kept on the dispatch and retrieval dates, hence being aware of the items locale at all times. Trade shows typically need certain tools for tracking and maintaining the information needed with relation to the equipment being used. A great initial option would be a program such as Excel, to track the necessary data. However, Excel may not be the most effective...

...FUNDAMENTALS OF SURFACE MODES: ¥ COLLOIDS ¥ means ÒglueÓ in Greek ¥ was coined in 1861 by Thomas Graham. ¥ ¥ ¥ ¥ ¥ WHAT IS A COLLOID? usually consists of two phases; one continuous phase in which the other phase is dispersed. Size of particles: larger than the size of molecules and small enough for the dispersed phase to stay suspended for a longer period of time. ¥ No strict boundaries for the size limits. OFFICIAL DEFINITION ¥ In 1903 Wolfgang Ostwald formulated the official definition of a colloid: ¥ a system containing entities having at least one length scale in between 1nm and 1µm. ¥ For smaller particles there is no distinct boundaries between the phases and the system is considered a solution; ¥ for larger entities the particles will fall to the bottom due to the gravitational force, and the phases are separated. 1 2 3 MESOSCOPIC PHYSICS ¥ The particle size is in the so-called mesoscopic range in between the macroscopic and microscopic limits. LARGE INTERFACIAL AREA ¥ One very important quality of the colloids is the large interfacial area between the dispersed and the continuous phases. WHAT EFFECTS HAS THIS? ¥ This means that interface effects and hence the electromagnetic surface modes, are very important for the properties of the colloids. ¥ It costs energy to create this much surface and the particles would clump together if this isnÕt prevented. ¥ Usually the particles are charged and hence repel each other. 5 6 4 Four states...

... it increases the water movement out of the plant by a process called transpiration. When there is a shortage of water, the guard cells well get smaller and close the stomata, and the transpiration process will move slower. The osmolarity would be tested with solute concentrations ranging from 0.0 M to 0.6 M. The concentrations increased 0.1 M each time and the solute used was sucrose. The goal of this experiment was to determine which concentration had the least effect on the potato after being incubated. This information helped us estimate the osmolarity of the potato tuber tissue. Our group hypothesis is that the osmolarity of the potato will have the concentration with the 0.1 M solution. This hypothesis is based off the predicted outcome that smaller molarity concentrations will have the least effect on the potato. The more solute added to a solution decreases the concentration of water in most cases (Kosinski). The decrease in water concentration would then lead to a lower weight of the potato tuber once it has finished incubating. Methods & Materials: For experiment A you will need the following items: 1 large potato tuber Forceps petri dish razor blade DI water metric ruler 7 250 mL beakers/ or disposable cups balance that weighs to the nearest 0.01g sucrose...

...The data solute concentration of the egg was found by taking the average percent change in mass for each percent solute concentration used in the lab and putting the data into the graph(Mass vs. Solute Concentration Over 3 Days). According to the data from the class, the solute concentration inside an egg is 25.1%. The egg would be in an isotonic solution at 25.1% solute concentration. This is when the concentration outside the egg is equal with the concentration of water inside the egg. The point of equilibrium is the point at which the trendline crosses the x-axis. At this point, the egg would no longer gain or lose mass. If the concentrations are the same inside and outside the egg, diffusion will not be able to take place. All averages...
