MAC AB:CD:EF:01:01:01 may be in the US and MAC AB:CD:EF:01:01:02 may be in Australia. So a router would have to keep track of where every individual MAC is in the world and how to get to it. That just isn't feasible. With an IP address you can be fairly sure that IP 1.2.3.2 and 1.2.3.3 are on the same network and the router that looks after the subnet they live on will know who is who. Therefor your router (or your ISP's) need only to know how to get that networks router. Reducing the amount of routes it needs to know by a couple of magnitudes.

Question No: 35 ( Marks: 3 ) What is concept of “fair use” in copyright law? There is a concept of ‘fair use’ or ‘fair dealing’ in copyright law that provides legitimate exceptions to copyright violation. Generally, fair use of a copyrighted work includes copying it for use in criticism, comment, news reporting, teaching, scholarship or research. Experts draw support from this concept of ‘fair use’ to deal with the problem of copyright over the internet. It is also argued that in cases where the author of a work has himself provided a hyperlink leading to his work, he should be regarded as giving the implied authority or license to download or make copies of his work. In such an eventuality, the issue of copyright should not arise according to an opinion. Question No: 36 ( Marks: 3 ) Digital signatures are considered more reliable than paper signatures. Do you agree with this statement? Briefly justify your answer. 1+2 Question No: 37 ( Marks: 3 ) What is ERP? Briefly explain its use in an organization? (1 + 2) ERP is an approach that attempts to integrate all departments and functions across a company onto a single computer system that can serve all those different departments' particular needs. For example, finance, manufacturing and the warehouse department of a company may have their own software to perform tasks specific to each one of them. However, each software can be linked together so that a customer service representative can see the credit rating of a customer from finance module, warehouse information from warehouse module, and shipment information from the shipment module. SAP is an example of ERP software. ERP is complex. It is not intended for public consumption as proper integration of ERP with ecommerce applications is still a major problem. Question No: 38 ( Marks: 5 ) What do you perceive by Value Added Network? Explain its advantages too with reference to EDI. (2+3) Value added networks are third party networks that provide services to execute authorized transactions with valid trading partners using EDI. Each VAN has a centralized computer system that maintains two files for each user, that is, Postbox: where outgoing messages are placed, and Mailbox: where incoming messages can be picked up. Advantages: Two big advantages of using a VAN in EDI are time independence and protocol independence. Time independence means that the sending and receipt of the interchange or messages can be carried out at the convenience of the users involved. Thus, they are not required to be connected with each other at the same time. Protocol independence means that interchanges are re-enveloped with the transmission protocol appropriate to the recipient when they are retrieved from the postbox by the VAN. Thus, a VAN can provide protocol compatibility between the sender and the recipient, wherever that is missing. Question No: 39 ( Marks: 5 ) What is ACH? What is its role in Virtual PIN system? 2+3 ACH stands for Automated Clearing House.A house through which the bank of payee clears the check with the help of traditional automated clearing house. Role of ACH in Virtual PIN System: A deposit request encrypted with bank’s public key accompanies the payment information. E-cash bank maintains a database of spent coins. On receipt it checks whether the coin is valid and whether it has already been spent or not (to prevent double spending) by referring to its database. If the coins are valid the bank credits the merchant’s account. Thus, if the client has sent valid coins worth $10 for payment to the merchant, and the merchant already has $90 in his account then an amount of $ 10 would be added in his account making it $ 100. Later, the merchant can request the e-cash bank to transfer this amount in his account with the acquirer bank. This can be done through ACH and the merchant can physically withdraw the money form the acquirer bank. Question No: 40 ( Marks: 10 ) What is data warehousing? What are its main tasks? What is its importance for an organization? The primary concept behind data warehousing is that the data stored for business analysis can most effectively be accessed by separating it from the data in the operational systems. A data warehouse, therefore, is a collection of data gathered from one or more data repositories to create a new, central database. For example a hospital may create a data warehouse by extracting the operational data it has accumulated concerning patient information, lab results, drug use, length of stay, disease state, etc,. Data Warehousing is not just the data in the warehouse, but also the architecture and tools to collect, query, analyze and present information. Question No: 41 ( Marks: 10 ) Precisely explain the steps of “Knowledge discovery from database” in order of their occurrence. Answer: Knowledge discovery process include Data cleaning, Data selection, Data transformation, Data Mining, Data integration, Pattern evaluation & knowledge presentation. Explaination of each step: 1-Data cleaning Data cleaning means that missing values should be provided in different fields/columns wherever needed and any impossible or erroneous values should be substituted by correct/reasonable ones. For example if the age of a person is typed as 1000 years in the column ‘age’ then an average age value can be put in its place. 2-Data selection Where there are quite a few erroneous or missing values in a row, then that row can be discarded/deleted altogether. This process is called data selection. 3-Data transformation In data transformation, the data from all different sources is converted into the same format. For example, date typed under a column should be in the same format in the entire data collected through different sources. 4-Data integration In data integration, data from all the sources is assembled or integrated into one and housed in the data warehouse. 5-Data Mining Now, this cleaned, transformed, selected and integrated data is fed to the data mining tool from a data warehouse for data mining purpose. 6-Pattern evaluation & knowledge presentation The results/ patterns are evaluated by managers and useful knowledge is thus gained. Note that almost 80% of the total time used in a knowledge discovery process is spent on just making the data fit for mining, that is, data cleaning, data transformation, data selection etc. FINALTERM EXAMINATION Fall 2009 IT430- E-Commerce (Session - 1) Question No: 1 ( Marks: 1 ) - Please choose one Key version represents public key by ► Buyer ► Seller ► E-Bank ► Certification Authority Question No: 2 ( Marks: 1 ) - Please choose one SSL stands for ► Secure Socket Layer ► Security Service Layer ► Sub Secured Length ► None of these Question No: 3 ( Marks: 1 ) - Please choose one How many kinds of Web Portals are?

As a marketer, when you are aiming at marketing your business in the entire world, you have to keep certain considerations in mind. Your web design must provide content in various languages and provide prices in various currencies, so that people belonging to different countries/cultures can understand the information contained in your web site. A regular display of currency exchange rate information can be useful in this behalf. Today, tools exist that can translate emails and your web sites into different languages. Another important consideration should be as to whether the country where you are doing the business has the required infrastructure to support your e-business. For example, whether you have a proper distribution channel of your products in a country you are doing business in. Similarly, you should carefully choose a payment system for your e-business which is compatible with the environment of a country where you are doing business. For example, a payment mechanism using SET cannot be considered as compatible with business environment in most of the third world countries. Question No: 41 ( Marks: 10 ) Give an example to show how members of supply chain can work together to reduce inventory, increase quality of product, reduce production cost and increase process speed. In 1997 the company had to stop its two assembly operations for several weeks due to errors in production and scheduling system causing it a huge financial loss. Thereafter, it decided to invest in information systems in every element of its supply chain. Involving its suppliers in the process, it began the use of EDI and internet technology, so that the suppliers could supply the right part or assembly at right time to prevent production delay. Now, the suppliers could get engineering specifications and drawings before the start of manufacturing using a secure internet connection, and plan their own business activities, accordingly. Also, members of the supply chain could have the knowledge of the completion of milestones and any changes in production schedule. In two years time, this approach resulted in reducing half the time needed to complete individual assembly processes. Thus, instead of waiting for 3 years the customer airlines could now have the ordered airplane ready for delivery in 10-12 months. Furthermore, the company launched a spare parts web site for ordering replacement parts. The site allowed customer airlines to register and order for replacement parts through browsers. Soon, the site was processing 5000 transactions per day at much lower cost as compared to orders cost through phone, mail, or fax. It also improved customer service in the sense that most parts could now be delivered the same day or the next day.
