1.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.
2.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).
3.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.
4.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.
5.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.
1.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.
2.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).
Discussion Activity 2
The various risks of IT sourcing are the dubious accessibility, loss of personal touch, lower protocols of security.
3.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.
4.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.
5.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.
1.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).
2.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.
3.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.
Discussion Activity 3
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.
4.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.
5.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.
1.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.
2.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.
3.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.
4.Blogging can be defined as the personal web log of an individual, where the person journals about his or her day.
Discussion Activity 4
Blogging plays an important role in businesses. The customers or the clients have a clear idea what the organization is up to and gets a daily idea of the ups and downs of that particular organization (Laudon and Laudon 2015). This increases the customer relationship management between the client and the company.
5.Intranet is a network by which the employees of an organization can easily create, collaborate, communicate and develop the culture of the company. The purpose is to provide network to everyone in the company.
Extranet is the network that provides limited access to only authorized customers, partners, vendors or any other persons. The purpose is provide network to only restricted users for protecting the network.
1.The GIS or global information system can be defined as an information system that is being developed for utilizing globally. This type of information system attempts in delivering the complete measurability of data globally within defined context (Petter, DeLone and McLean 2013). It is utilized by various organizations for spreading their businesses worldwide.
2.For resolving this conflict, a global information system is required. This type of information system would be extremely beneficial for both the European Union and the United States companies. This would be protecting the data perfectly without any type of complexities. Thus, the conflict would be resolved.
3.Data modelling is the first step in database designing as well as object oriented programming. The designers at first create the conceptual model for looking how the data items are related to each other. Further, it progressed to the logical model to physical schema. The two most important examples of data models are Hierarchical database model and Relational model.
4.Sensitivity test or analysis is the theoretical study of analyzing the uncertainty of the output of any mathematical system or model. It is extremely important to identify the uncertainty in the results.
Two examples of the sensitivity tests are Decision making and Communication.
5.A geographic information system could be utilized for scheduling the classes easily by simply capturing, storing, manipulating, managing, analyzing and thus presenting the geographical data (Chang 2015). It helps to create interactive queries and thus classes could be easily scheduled.
One such example is Python.
