IT FOR BUSINESS
Discussion Activity 1
Question 1
Answer: This statement is inadequate as an information system comprises of various
other things as well like telecommunications, human resources, procedures, data warehouses
and several databases (Laudon and Laudon 2015). With all these components, when
computer software and hardware is added, it is known as an information system.
Question 2
Answer: A problem can be defined as any particular situation or matter that is
regarded as harmful or unwelcome and should dealt to overcome.
The most significant example of business problem is data security and privacy.
Computer based information system helps to increase the data security by providing
secured location of data storage and data manipulation (Galliers and Leidner 2014).
Question 3
Answer: Yes an off the shelf computer program can be utilized as strategic
information system as the off the shelf computer program provides training, support,
development influence, price, software updates as well as upgrades, fitness for purpose, trials,
ownership to its clients. These advantages are also present in strategic information system.
Question 4
Answer: The strategic information system offers corporation short lived advantages
often because of the fact that the competitors solely imitate the leader and thus the advantage

finishes or diminishes (Pearlson, Saunders and Galletta 2016). This is the one and only
reason.
Question 5
Answer: Adobe encourages the PC users for downloading the Flash Player and
Acrobat Reader completely free of cost. Strategically, it helps the Adobe as both of the
products belong to it and applying anything on these two products is never free of cost
(Davies, Dean and Ball 2013). Thus, Adobe is making money indirectly.
If they give the application away, their generosity would help them to make money by
the software itself. After few months of usage, the software has to be upgraded and they can
easily make money from that.

Question 1
Answer: The main advantage of agile over waterfall model is that it does not a
sequence of processes throughout the project execution. It is very fast and effective (Rainer et
al. 2013). The deliverable of the project is produced as well as accepted incrementally within
short iterations. This is absent in waterfall model.
The main risks of agile model involve lack of documentation makes the new members
of the project difficult to understand. The next risk is that it requires more cost and time and
hence often it crosses budget.

Answer: The benefits of IT sourcing are the saving of money, controlling expenses,
focusing on the core operations, involving more IT resources (Petter, DeLone and McLean
2013).
The various risks of IT sourcing are the dubious accessibility, loss of personal touch,
lower protocols of security.
Question 3
Answer: Yes the development of the information systems by the end users should
always be encouraged. The end user computation within the organizations with separate
strategies of information system helps in the determination of the characteristics and nature of
the entire user developed applications, practices of system development, methods of quality
assurance and the procedures and policies of the end user (Power, Sharda and Burstein 2015).
Yes since it comprises of various benefits, the risks are outweighed.
Question 4
Answer: Supply chain can be defined as the system of people, activities, resources
and information that helps to move any service or product from the supplier to the customer.
The main purpose of supply chain management is to manage the flow of services and
goods in a periodical manner by means of interlinked networks (Cassidy 2016). It is the
designing, planning and controlling of supply chain activities.
Question 5
Answer: Radio Frequency identification is a chip that utilizes electromagnetic fields
for tracking and identifying tag or objects. It is extremely efficient and can be utilized in all
businesses.

RFID is used in SCM for the purpose of tracking and identifying the goods and
services (Kravets and Lapshina 2013). It helps to maintain the supply of the goods well and
good and so that no repetition or mistake is occurred.
Discussion Activity 3
Question 1
Answer: For buying a computer, few important and most significant parts are
required. Without these parts, it is not possible to assemble a complete computer. The basic
parts of any particular computer system are the monitor, Central Processing Unit or CPU,
Keyboard, Mouse, Speakers, Scanner and Printer (Beletskaya et al. 2013).
Question 2
Answer: The important features before buying a new computer system mainly include
usability, price, type of the operating system, size of the computer monitor, peripherals, brand
of the company, size of hard disk, Random Access Memory, Processor and Warranty of the
product.
Question 3
Answer: LAN or Local Area Network: It is a computer network, which works in a
very small area like a single room, a building or an apartment.
WAN or Wide Area Network: It is a computer network that works in a larger
geographical area of radius over 1km. it comprises of two LANs (Laudon and Laudon 2015).
MAN or Metropolitan Area Network: It is a computer network that works in a larger
geographical area than LAN, however smaller than WAN.

PAN or Personal Area Network: It is a computer network that works for the
transmission of data within devices like telephones, computers, tablets and many more.
Question 4
Answer: The main advantages of optical fibre over any other communication media
mainly include extremely higher bandwidth, lower loss of power, faster speed, high carrying
capacity, cost effective, thinner, light weighted, light signals, lower signal degradation, longer
lifespan and many more. Thus, it is accepted by all users.
Question 5
Answer: Yes there is certain downside to this pervasiveness of Wi-Fi in everywhere.
The first and the foremost problem of this availability of Wi-Fi is that the students and the
youth generation are more involved into Internet connection and not in their studies (Petter,
DeLone and McLean 2013). The second problem is that people are not being able to work
properly. Moreover, Wi-Fi brings out security issues; there is a high chance of data loss when
it is being used on Wi-Fi.
Discussion Activity 4
Question 1
Answer: Database management system help to organize data or records effortlessly
and effectively. These are organized by various fields, records or files. Spreadsheets is a
particular computer program, which is used for recording and analyzing numbers. The
example that database can do and spreadsheets cannot is that database can perform data
operations, while spreadsheets cannot (Davies, Dean and Ball 2013). The second example is
that database can quickly select any information and makes the search easier; however
spreadsheets enable to produce charts and graphs from that data.

Question 2
Answer: Data cleansing is the procedure for detecting as well as correcting the
inaccurate or corrupted records or data from any particular set or table of records for the
successful identification of incomplete, inaccurate data parts and thus replacing and
modifying them. This is done before storing the data warehouse as it provides more space in
the warehouse and also the data is secured.
Question 3
Answer: It is a large storage of data that had been accumulated from broader range of
sources within any specific organization and are utilized for taking management decisions. It
helps to maintain the data safely and securely without any type of complexities (Davies, Dean
and Ball 2013).
The main difference between transactional database and data warehouse is that
database is the information repository utilized for backing of data; whereas data warehouse is
a particular type of database that aims on applications like storage, filtering, analyzing and
retrieving of bulk amount of data.
Question 4
Answer: Blogging can be defined as the personal web log of an individual, where the
person journals about his or her day.
Blogging plays an important role in businesses. The customers or the clients have a
