What are the 5Vs of big data?

Variety, Volume, Velocity, Value, Veracity

What does 'Variety' in big data refer to?

Data from different sources in various formats (structured, semi-structured, unstructured).

What is 'Volume' in the context of big data?

Huge amounts of data that require significant storage space and/or a high number of observations.

What does 'Velocity' describe in big data?

The frequency of data generation and/or provision.

What is 'Value' in big data characteristics?

The extent to which data can provide insights through extraction and transformation.

What does 'Veracity' mean in big data?

The reliability and validity of the data.

What are some dimensions of information quality?

Timeliness, Accuracy, Clarity, Completeness, Relevance, Reliability.

What is the definition of a system as per systems theory?

A collection of interrelated components working together towards a collective goal.

What are the components of a work system?

Participants, information, technologies, processes and activities, products/services, customers.

What is the difference between open-loop and closed-loop control systems?

Open-loop systems take no action to modify processes after initiation, while closed-loop systems use feedback or feedforward control to adjust processes.

What resources support Business Information Systems (BIS)?

People, hardware, software, communications (processes, procedures), and data.

What categorizes the different types of Business Information Systems?

Operations information systems, management information systems, and transaction processing systems.

What is the distinction between Information Technology (IT) and Information Systems (IS)?

IT refers to the technology itself, while IS uses IT to create management information.

What is an example of a disadvantage of computer processing?

Computer-based information systems cannot use human judgement or intuition effectively.

What is a virtual machine (VM)?

A software emulation of a physical computer that can run multiple operating systems.

What does Moore's Law state?

The prediction that transistor density on semiconductor chips will double approximately every 18 months.

What is the purpose of a content management system?

To help users create and manage web sites quickly without technical knowledge.

What are the basic hardware components of a computer system?

Input device, memory, central processing unit, output device, storage device.

What are the categories of computers?

Mainframe, minicomputers, microcomputers, and client/server systems.

What is the function of system software?

To manage and control the computer system's operations on behalf of the user.

What is e-business?

The use of Information and Communication Technologies (ICT) to conduct business, especially via the Internet.

What is the role of Business Information Systems (BIS) in decision-making?

To support managers in making decisions to help the organization function properly and achieve objectives.

What are some success factors of a Human Resource Information System (HRIS)?
