Potential Test 2 Questions (Part II)

As promised here are the potential short-essay and terms for the final three lectures of the second half of the term.

Short-Essay Questions

- when preparing your answers for these short-essay questions, please keep in mind that each question is worth 4 marks which implies that you need to make at least four points. Also, please note that terms like Describe, Discuss, Differentiate mean that we are looking for a sentence or two for each point (not just a list of terms). The questions below contain five (5) short-essay questions from each lecture (or lecture/seminar combination). Two (2) short-essay questions from each set of 5 will appear on Test 2 (for a total of twelve (12) questions total from the two sets of questions released as Part I and Part II). For Questions 6-8 from Lecture 10 and Question 15 from Lecture 11, if one of these were to appear on Test 2, it would have the same format but the actual numbers will be different. This means you cannot just memorize the answers, but must know how to actually do the math.

Lecture 9 (Brian Patrick)

Briefly describe four of the five steps that an organization typically follows when it decides to

implement Web-based e-commerce.

Explanation / Answer

LECTURE-9:

Following are the steps that an organization typically follows when it decides to
implement Web-based e-commerce are mainly:

1.Research and strategy

The core focus of any e-Commerce website design should be clear communications between the web development company and the client.
It is very important that the designers and developers have a clear understanding of the company, the product and the industry as
a whole.

2. Planning

This involves setting down all the requirements for the new e-Commerce site as well as its participants. What are the requirements
for users? Content? Search? Landing pages? This is the time to ask yourself crucial questions regarding how much (or how little)
knowledge someone must have about your product or service to make a purchase.

3.Information Architecture

Here you’ll consider the navigation and layout of the site as well as best practices for overall user experience. How easy is it
for your potential customer to find what they’re looking for quickly and easily?

4. Construction
This is the “nuts and bolts” behind any solid, reliable e-Commerce website, including client and server-side applications (front
end and back end programming), quality assurance testing, integration of third party tools and other solutions that will make
your e-Commerce website scalable as it continues to grow.

Electronic customer relationship management provides an avenue for interactions
between a business, its customers and its employees through Web-based technologies.
The process combines software, hardware, processes and management’s commitments
geared toward supporting enterprise-wide CRM business strategies.
Businesses that strategize and implement an E-CRM solution are able to align
their processes around technology to effectively deliver seamless, high-quality
customer experience across all channels. Customers have the power to help themselves
through online personalized services that are made available on demand.

ADVANTAGES OF E-COMMERCE:

1. Cost Effective

The entire financial transactions will eventually become electronic, so sooner conversion is going to be lower on cost. It makes every transaction through e-commerce payment a lot cheaper.

2. Higher Margin

E-commerce also enables us to move better with higher margin for more business safety. Higher margin also means business with more control as well as flexibility. You can also save time from the e-commerce.

3. Better Productivity

Productivity here means productivity for both companies and customers. People like to find answers online because it is faster and cheaper, and it costs a lot cheaper expense as well for the company.

4. Quick Comparison

E-commerce also enables you to compare price among several providers. In the end, it leads you to smart shopping. People can save more money while they shop.

5. Economy Benefit

E-commerce allows us to make transaction without any needs on stores, infrastructure investment, and other common things we find. Companies only need well built website and customer service.

DISADVANTAGES OF E-COMMERCE:

1. Security

Customers need to be confident and trust the provider of payment method. Sometimes, we can be tricked. Examine on integrity and reputation of the web stores before you decide to buy.

2. Scalability of System

A company definitely needs a well developed website to support numbers of customers at a time. If your web destination is not well enough, you better forget it.

3. Integrity on Data and System

Customers need secure access all the time. In addition to it, protection to data is also essential. Unless the transaction can provide it, we should refuse for e-commerce.

4. Products People

People who prefer and focus on product will not buy online. They will want to feel, try, and sit on their new couch and bed.

5. Customer Service and Relation Problem

They sometimes forget how essential to build loyal relationship with customers. Without loyalty from customers, they will not survive the business.

MOST COMMON UNETHICAL USES OF DIGITAL TECHNOLOGIES ARE:

1.Pirating is one of the most common ways to use a computer
unethically. Pirating includes downloading software or files,
including games, movies and photo-editing programs.

2.Hacking is another way to use computers unethically. Hacking
is the act of invading another person's files or computer to
take valuable assets or information. Hacking can also quickly
turn into identity theft and exploitation.

3.Bullying is a rising trend in cyberspace, especially with the
popularity of social networks, such as Twitter and Facebook.
Bullying is the act of intimidating someone through violent or
threatening means.

TWO PHYSICAL HEALTH CONCERNS:

1.Addiction to the computer for a long time leads to headache and backbone pain.
2.The harmful electronic rays coming out from screen deeply effects human eyes and tends to different problems.

TWO EMOTIONAL HEALTH CONCERNS:

1.Using computers in every context can lead to frustration,dippression etc in case of slow response or system hang.
2.Addiction to social medias become the most common reason of harassment.

Perform the following operations assuming 6-bit 2’s complement binary numbers.
110001 + 001111

110001
+ 001111
-----------
000000
+ 1
------------
000001

010011 – 111100

2's complement of 111100

000011 + 000001 = 000100

010011 + 000100 = 010111

Convert the binary number 1010 1101 1011 1101 to octal:

1010110110111101

group the bits into group of three bits from right:

010 101 101 101 111 101 (Add 0 if last group not includes 3 bits)

Add a 4, 2, and a 1 underneath each set of three numbers to note your placeholders.

010 101 101 101 111 101

421 421 421 421 421 421

If there is a one above the "4," then your octal number has a 4 in it. If there is a 0 above the one's place, the octal number does not have a one in it, so leave a blank, zero, or dash.

010 101 101 101 111 101

421 421 421 421 421 421

020 401 401 401 421 401

now add all the bits of each group:

(0+2+0)(4+0+1)(4+0+1)(4+0+1)(4+2+1)(4+0+1) == 255575 --> octal number

Convert the binary number 1010 1101 1011 1101 to hexadecimal:

group these bits into 4 bits and convert into decimal:

1010 1101 1011 1101

10 13 11 11

A D B B

== ADBB

Convert the hexadecimal number A1B2 to binary:

Just reverse the process of binary to hexadecimal,

A1B2

10 1 11 2

== 1010 0001 1011 0010
