QUESTION 1(a)(i)

Q Distinguish between the "e-wallets" and "bank transfers" e-commerce payment methods.
A

Solution


Definition and Function:

➧ E-Wallets:

E-wallets, also known as digital wallets or mobile wallets, are electronic payment systems that store users' payment information, such as credit card details, bank account information, or prepaid balances. Users can load funds into their e-wallets, either from their bank accounts or by linking their credit/debit cards. During an e-commerce transaction, customers can select the e-wallet as their payment option and authorize the payment from their stored funds or chosen payment source. E-wallets provide a convenient and secure way to make online purchases without directly sharing sensitive financial information with the merchant.

➧ Bank Transfers:

Bank transfers involve the direct transfer of funds from the customer's bank account to the merchant's account. When a customer selects bank transfer as the payment method during an e-commerce transaction, they are redirected to their online banking platform. They must log in and initiate the payment manually, providing the necessary transaction details. The funds are then transferred from the customer's bank account to the merchant's bank account. Bank transfers are typically conducted through electronic funds transfer (EFT) systems and are often used for larger transactions or in B2B e-commerce.

Payment Process:

➧ E-Wallets:

The payment process with e-wallets is quick and straightforward. Users only need to select the e-wallet as the payment method, and the necessary payment information is automatically retrieved from the e-wallet. Users may need to authenticate the payment with a PIN, fingerprint, or other security measures. Once authorized, the payment is completed instantly, and the transaction details are shared with the merchant.

➧ Bank Transfers:

Bank transfers involve a more manual process. After selecting bank transfer as the payment method, users are redirected to their online banking platform to complete the payment. They need to log in, enter transaction details (such as recipient's bank account number and transaction amount), and authorize the payment. The transaction may take some time to process, depending on the bank and payment system used. The funds are transferred from the customer's bank account to the merchant's bank account, and the merchant is notified of the payment once it is confirmed.

Availability and Accessibility:

➧ E-Wallets:

E-wallets are widely available and accessible to users through mobile apps or web-based platforms. Many e-wallet services are compatible with various devices, including smartphones, tablets, and computers. Users can easily load funds into their e-wallets and make payments with just a few clicks.

QUESTION 1(a)(ii)

Q In an era of identity theft and impersonation, security is among the primary concerns that restrains consumers from engaging in e-commerce

With respect to the above statement, examine critical functions that are performed by a secure electronic transaction (SET) system.
A

Solution


➧ Confidentiality:

Confidentiality ensures that sensitive information exchanged during a transaction remains private and protected from unauthorized access. In a SET system, confidentiality is maintained through the use of encryption techniques. Encryption encodes the data into an unreadable format that can only be deciphered by the intended recipient with the appropriate decryption key. By encrypting data such as credit card details, personal information, and transaction details, a SET system ensures that this information remains confidential and inaccessible to unauthorized parties.

➧ Integrity:

Integrity ensures that the data transmitted during a transaction is not altered or tampered with during transit. In a SET system, integrity is achieved through the use of digital signatures and message authentication codes (MACs). Digital signatures are cryptographic techniques that provide a means to verify the authenticity and integrity of digital messages. They are generated using the private key of the sender and can be verified using the corresponding public key. By digitally signing the transaction data, the SET system ensures that any modifications or tampering with the data can be detected by the recipient. Similarly, MACs use cryptographic algorithms to generate a unique code that represents the integrity of the data. This code is transmitted along with the data and allows the recipient to verify its integrity upon receipt.

➧ Authentication:

Authentication ensures that the parties involved in a transaction are who they claim to be. In a SET system, authentication is achieved through various means, such as the use of digital certificates and secure protocols. Digital certificates are issued by trusted certificate authorities (CAs) and provide a means to verify the identity of individuals or organizations involved in a transaction. These certificates bind a public key to an entity and are used to establish secure communication channels. Secure protocols, such as Secure Socket Layer (SSL) or Transport Layer Security (TLS), provide encryption, authentication, and integrity services to secure the communication between the client and the server. By employing these authentication mechanisms, a SET system ensures that only authorized and authenticated parties can participate in the transaction.

QUESTION 4(e)

Q (i) Define "cell referencing" in the context of spreadsheet applications.

(ii) Using an example, explain one type of cell referencing.
A

Solution


(i) In the context of spreadsheet applications

Cell referencing refers to the method of referring to specific cells within a spreadsheet by using a unique identifier. Cell references allow users to dynamically link and manipulate data across multiple cells, formulas, and functions.

One type of cell referencing commonly used is called "relative cell referencing." In this type, the reference to a cell is based on its relative position to the cell containing the formula or function. When a formula or function is copied or dragged to other cells, the cell references adjust automatically based on their relative positions.

(ii) For example

Consider a spreadsheet that contains sales data for different products in columns A and B. In column C, we want to calculate the total sales for each product by multiplying the quantity (column A) with the price per unit (column B). Let's assume the formula for the first row in column C is "=A1*B1".

If we copy or drag this formula to the second row, the relative cell references adjust accordingly. The formula in the second row would automatically update to "=A2*B2", referring to the cells in the same row as the formula. Similarly, if we copy or drag the formula to subsequent rows, the cell references will continue to adjust based on their relative positions.

This relative cell referencing allows us to apply the same formula or function to multiple cells while maintaining the appropriate relationship between the data. It simplifies the process of performing calculations or applying functions across a large dataset, as the references adjust automatically based on the relative positions of the cells involved.

Solution


Let's consider an example where you have two worksheets in an Excel workbook:
"Sheet1" and "Sheet2." In "Sheet1," you have a list of products with their corresponding prices, and in "Sheet2," you want to display the total sales for each product.

Here's how you can use a formula to link the data between the two worksheets:

In "Sheet1," enter the product names in column A starting from cell A2, and enter the corresponding prices in column B starting from cell B2.

For example:

A B
Product Price
A 10.00
B 15.00
C 12.00


In "Sheet2," where you want to display the total sales for each product, enter the product names in column A starting from cell A2.

For example:

A B
Product Tota sales
A
B
C


In cell B2 of "Sheet2," enter the following formula:

=SUMIF(Sheet1!$A$2:$A$4, A2, Sheet1!$B$2:$B$4)

This formula uses the SUMIF function to calculate the total sales for each product. It searches for matching product names in "Sheet1" (A2:A4), and when a match is found, it adds up the corresponding prices (B2:B4).

Copy the formula from cell B2 and paste it into the remaining cells in column B of "Sheet2" (B3:B4).

Once you enter the formula in cell B2 and copy it down, "Sheet2" will display the total sales for each product based on the prices listed in "Sheet1." The formula will automatically update if you make any changes to the prices in "Sheet1."

A B
Product Total sales
A 10.00
B 15.00
C 12.00
