It has been said that the advantage that leading-edge retailers such as Dell and Wal-Mart have over their competition isnt technology, its their management. Do you agree? Why or why not? Solution I absolutely agree. It is true that certain technology, such as Wal-Mart\'s continuous inventory replenishment system, can give certain firms a competitive edge to start. Over time however, other firms in the industry will be able copy and adopt similar technologies. What really sets firms like Wal-Mart and Dell is the business models they have created, for example Dell\'s direct-sales approach to the marketing of their products, and specifically their ability to adopt radically different business processes which leverage the technology at their disposal. The creation of business models and the shaping of business processes are management responsibilites, and thus management should receive credit for the successes of both Wal-Mart and Dell. (D.B) .

ISP who has allowed them the use of 4 externally routable IP addresses to transmit data across the Internet. Assuming that only non-privileged ports are used, what is the maximum simultaneous number of TCP connections that can be supported through a NAT gateway using those 4 addresses? Solution NAT behavior for source TCP port range for connections is unspecified. as the port number is 16 bit, there can be 65535 TCP connections can be defined for any given client. provided the listening port is open. The NAT allocates a mapping for the first initiated connection by the internal endpoint to the external endpoint in case of externally initiated connections.These connections can be re used some times. In this scenario, TCP can have maximum 4 simultaneous connections at any given time. .

Is TOD a input or output?? Is this correct?>> Inputs: start, stop, flow meter, counter Outputs: pump and full light. Not sure if TOD is a input or output. A TOD is use to take the interger value in the counter accumulator, convert it to BCD(binary coded decimal) and then move this BCD value to the control panel LED display (O:4). Solution Inputs to PLC are Start,Stop,Flow meter, Counter Counter acts as input in the sense that when counter reaches a set value DN bet is set and From the memory input is send to control the light and pump. Outputs:Full Light, Pump. CU and DN are also outputs whose values are stored in memory and which are then used as inputs. TOD is neither input nor output. It is just an intermediate stage for data manipulation i.e. convert integer to BCD value. .

Is a public park considered to be a public good? Why or why not? Solution In economics, a public good is a good that is both non-excludable and non-rivalrous in that individuals cannot be effectively excluded from use and where use by one individual does not reduce availability to others. Gravelle and Rees: \"The defining characteristic of a public good is that consumption of it by one individual does not actually or potentially reduce the amount available to be consumed by another individual\". Public goods include fresh air, knowledge, lighthouses, national security, flood control systems and street lighting. Public goods that are available everywhere are sometimes referred to as global public goods. [1] There is an important conceptual difference between the sense of \'a\' public good, or public \'goods\' in economics, and the more generalized idea of \'the public good\' (or common good, or public interest),\" .

Iron(II) ion reacts with water to a small extent by a hydrolysis reaction: Kc 2 x 107 Sulfuric acid was added to the stock Fe+ solution to prevent this hydrolysis. How would you final result for the % iron change if you forgot to add the 5 drops of 6M H2SO4 to your iron unknown? Explain. (assume FeOH does not react with o-phen) Solution Hydrolysis of Fe2+ is prevented by the addition of 5 drops of 6 M H2SO4. If we forgot to add this H2SO4, the % iron found would be lower than the expected value as the hydrolyzed Fe2+ would not form the o-phen complex and fails to contribute to the final absorbance value. Absorbance is directly proportional to concentration of Fe-phen complex in solution .
