4 non-routine cognitive skills - correct answer Abstract reasoning, systems thinking, collaboration, and ability to experiment 3 Broad reasons to why 'Intro to MIS' is important: - correct answer 1. Ultimate in job security - marketable skills - by helping you learn abstraction, systems thinking, collaboration, and experimentation. 2. Background to assess, evaluate, and apply emerging information systems technology to business. 3. Many MIS-related jobs available with strong market growth 4 laws that summarize rapid advancements in core aspects of computing: - correct answer Moore's Law - processing speed, the speed of a computer doubles every 18 months Kryder's Law - storage capacity, that the storage density on magnetic disks is increasing at an exponential rate Nielson's Law - data communications, network connection speeds for high-end users will increase by 50% per year. Metcalfe's Law - data communications, states that the value of a network is equal to the square of the number of users connected to it 5-component framework - correct answer An assembly of hardware, software, data, procedures, and people that produces information What is MIS? - correct answer 3 elements - management and use, information systems, and strategies Difference between IT and IS? - correct answer IT is only made up of hardware, software, and data; while IS is made up of IT (hardware, software, and data) and also procedures and people. What is a system (with examples)? - correct answer A system is a group of components that interact to achieve some purposes, examples - cell phone, computer, camera Difference between the 3 elements - correct answer Management and use, Information systems, and strategies. Management and use means develop, maintain, and adapt, it means to create an information system that meets your needs, take an active role in systems development. Information system - business processes need information technology. Strategies -information systems exist to help people in a business to achieve the business' strategies. Explain the input, process, output, and feedback framework. - correct answer Inputs are systems components that bring data/information into the system for processing. Process are the systems components that perform some computations/calculations/manipulations on incoming data/ information to generate output. Output is system components that display, store, or distribute processed data/ information produced by system as output. The feedback is a type of output component that provides information about correct functioning of input and processing steps and ensures that desired outcomes are not accompanied by undesirable consequences. Explain the difference between a system and systems thinking. - correct answer A system is just a set of interrelated components that work together to accomplish a common goal while systems thinking is the individual components of a system working together, which are interconnected, to make up a system Explain systems thinking conceptually, practically, and operationally. - correct answer Systems thinking conceptually is the process of understanding how things influence each other within the whole. Systems thinking practically is a problem-solving approach: any problem in a system is viewed as "belonging" to the system as a whole, rather than to the part of the system where the problem can be seen or where it first arose. Systems thinking operationally is built around the notion that individual components of a system can be understood in terms of their relationships to one another, rather than in isolation. 3 different applications of systems thinking in managing with IS. - correct answer Information system design and implementation, information system use, and information system repair and maintenance/problem solving. Define data and explain with examples. - correct answer Raw facts about something of interest. Examples - people, places, events, transactions, objects, etc. Explain how data can be distinguished from raw facts. - correct answer Raw facts simply exist in nature; data are only those raw facts that are relevant to decision-making. Explain variables and constants, and their relationship to data. - correct answer Variables are something that can have more than one value, a data category that can take on many values (ex. Student names, prices per unit of a set of products). Constants are a data item that can only take on a single value, each individual value within a data category (ex. the name of a single student, the price per unit of a particular brand of coffee on Aug 18, 2018). What is structured data? - correct answer Structured data is data in the form of rows and columns. Most of the time structured data means tables in a relational database, can refer to spreadsheet data as well. 80% of data today is unstructured. Explain what is information and how is information created from data? - correct answer Information is data organized in a meaningful manner. Information is created from the organization of data in a way to show how the raw facts are related. Explain, compare, and contrast between the characteristics of valuable information. - correct answer Valuable Information: · Accessible: info should be easily accessible by authorized users · Accurate: accurate info is error free · Complete: complete info contains all the important facts · Economical: info should be relatively economical to produce, must balance value of info with cost of producing it · Flexible: can be used for a variety of purposes · Relevant: must be relevant to the decision maker · Reliable: can be depended on; reliability depends on source of the info · Secure: should be secure from access by unauthorized users · Simple: not overly complex, too much info can cause info overload · Timely: delivered when it is needed · Verifiable: you can check it to make sure it is correct Explain what is BI, and what is its purpose. - correct answer BI is business intelligence which it uses data to drive decision-making.
