BCIS 2610 Exam 1 Study Guide
Study the various laws (Moores, Metcalfe,Bell, Nielsons, and Kryders) Moore’s Law: law created by Gordon Moore, stating that the number of transitors per square inch on an integrated chip doubles every 18 months. Moore’s prediction has proved generally accurate in the 40 years since it was made. Sometimes this law stated that the performance of a computer doubles every 48 months. Although this is not strictly true, this version gives the gist of the idea
Metcalfe’s Law: The value of a network is equal to the square of the number of users connected to it
Nielsen’s Law: Network connection speeds for high-end users will increase by 50% per year If you want to learn more check out louise nevelson white vertical water
Kryder’s Law: The storage density on magnetic disks is increasing at an exponential rate
Know the reasons and explanations of strong non-routine skills. Skills are abstract reasoning, systems thinking, collaboration, and the ability to experiment
Abstract reasoning: the ability to make and manipulate models
Systems thinking: the ability to model the components of the system to connect the inputs and outputs among those components into a sensible whole that reflects the structure and dynamics of the phenomenon observed
Collaboration: the activity of two or more people working together to achieve a common goal, result, or work product. Collaboration is only successful when a team can give and receive critical feedback Don't forget about the age old question of the affluent use hospital services more intensively than the poor
Experimentation: making a reasoned analysis of an opportunity, envisioning potential solutions, evaluating those possibilities, and developing the most promising ones, consistent with the resources you have
Know examples of data.
Data: recorded facts or figures
Understand the five-component model of information systems. Be able to name and describe them. Pay attention to terms such as actor.
- Five components are hardware, software, data, procedures, and people
- The outermost components, hardware and people, are actors which means they take actions
- Software and procedure components are both sets of instructions (software=instructions for hardware, procedure=instructions for people)
- Data is the bridge between the computer side of things and the human side of things
Know the difference between hardware and software. Study the examples.
- Hardware is all of the physical parts of a computer system while software is the collection of programs and other operating information used in the hardware
What is Google Project Loon (you also saw a video of it at the beginning of the course). Know the characteristics of good information.
Project Loon: a research and development project being developed X, formerly Google X, with the mission of providing internet access to rural and remote areas. The project uses high altitude balons placed in the stratosphere at an altitude of about 18 km (11 mi) to create an aerial wireless network with up to 4G LTE speeds Don't forget about the age old question of utd child development
- Good information is conceived from accurate, correct, and complete data that has been processed correctly as expected
What is the business user’s role in information systems?
- The business user understands the business needs and requirements, and has the ability to make changes based on info provided and data collected
Know the difference between structured and unstructured decisions.
Structured decision: process where there is an understood and accepted method for making the decision.
Example: a formula for computing the reorder quantity of an item in inventory Unstructured decision: process where there is no agreed-on decision making method Example: predicting the stock market
Know the difference between operational, managerial, and strategic levels. Also, understand how decisions are made at each level.
Operational decisions: decisions that concern the day-to-day activities of an organization
Managerial decisions: decisions that concern the allocation and use of resources Strategic decisions: decisions that concern broad-scope, or organizational issues Identify if an activity is a collaborative activity. Know the primary criteria for judging team success. Know why teams collaborate. We also discuss several other topics like ucsb pstat
- See earlier definition of collaboration
Team success: (according to Hackman) is that team members have a meaningful and satisfying experience
Be able to list the phases of project development and activities in each phase. Define project data and metadata.
- Phases of project development are starting, planning, doing, and finalizing - Starting: sets team authority, sets project scope and initial authority, forms a team, establish team roles and responsibilities, establishes team rules - Planning: determines tasks and dependencies, assigns tasks, determines schedules, revises budget
- Doing: performs project tasks, manages tasks and budgets, solves problems, researches tasks as necessary, documents and reports progress We also discuss several other topics like potatoes can be peeled commercially by soaking them in a 3-m to 6-m solution of sodium hydroxide, then removing the loosened skins by spraying them with water. does a sodium hydroxide solution have a suitable concentration if titration of 12.00 ml of the
- Finalizing: determines completion, prepares archival documents, disbands team
Project data: data that is part of the collaboration’s work product Project metadata: data used to manage a project
Define version management systems.
Version management: Tracking of changes to documents by means of features and functions that accommodate concurrent work
Know the difference between synchronous and asynchronous communication. Identify Hackman’s three criteria for team success.
Synchronous communication: Information exchange that occurs when all members of a work team meet at the same time, such as face-to-face meeting or conference calls
Asynchronous communication: Information exchange that occurs when all members of a work team do not meet at the same time, such as those who work different shifts
- Hackman’s 3 primary criteria for judging team success
o Successful outcome: meaning achieving of goals
o Growth in team capability: meaning did the team get better for the sake of better work processes We also discuss several other topics like notes of political parties class 10
o Meaningful and satisfying experience: more of a feeling than a direct goal. Did everyone receive rightful credit? Was a sense of camaraderie felt?
Understand the Principles of Competitive Advantage (Figure 3-12) enough to identify examples.
Understand Porter’s Four Competitive Strategies.
- Barriers to entry
- Switching costs: organizations can lock in suppliers by making it difficult to switch to another organization or by making it easy to connect to and work with an organization
- Establish alliances with other companies
- Reducing costs
What is Porter’s definition of value?
Value: not just tangible parts, but also the time required to contact the vendors for those parts, to maintain business relationships with those vendors, to order the parts, to receive the shipment, and so forth
What does Porter’s five forces model assess?
- Porter recognized a movement to create integrated, cross-departmental business systems
- Porter’s work eventually led to the creation of a new discipline called business process design.
o This idea says that organizations should not automate or improve existing functional systems, instead they should create new and more efficient business processes that integrate activities from all
Know the activities in the value chain. Know what happens during each activity. Understand how business processes generate value.
Inbound logistics: receiving, storing, and disseminating inputs to the products Operations manufacturing: transforming inputs into the final products
Outbound logistics: collecting, storing, and physically distributing the products to buyers
Sales and marketing: inducing buyers to purchase the products and providing a means for them to do so
Customer service: assisting customers’ use of the products and thus maintaining and enhancing the products’ value
Know the parts of the computer.
House: part of your computer that holds all the parts that make the computer operate Motherboard: part of your computer that wires all of the other parts together Processor (CPU): responsible for interpreting every code it receives from the other computer components and making it usable to your operating system Hard drive: part of computer that stores your information
Display adapter: interprets video signal
RAM (memory): instant memory, always in use as a temporary location to execute instructions from your computer
Optical drive: uses light to read and write data, it’s the drive used to burn CDs and other disks. Can either be slot loading or tray loading
What language does an Android applications use? What language does a Mac use? What is the difference between a thin and thick client
- Android apps use Java
- MacOS uses Objective-C
Thick client application: a software application that requires programs other than just the browser on a user’s computer: that is, requires code on both client and server computers (aka native application)
Thin client application: designed to run within a computer browser such as firefox or chrome. Also known as a web application. Web applications run within the browser and can run on any type of computer and ideally runs on any type of browser (though this isn’t always the case)
Know the different operating systems. Know the benefits of self-driving cars.
- Three most common operating systems are Microsoft Windows, Mac OS X, and Linux
- Benefits of self-driving cars include… fewer accidents, decreased traffic congestion, increased highway capacity, lower fuel consumption, enhanced human productivity, hunting for parking is eliminated, improved mobility for those who aren’t currently allowed to drive, less traffic violations, higher speed limits, lighter and more versatile cars
Understand the difference between closed and open source software. How does a mobile network work?
Closed source: source code that is highly protected and only available to trusted employees and carefully vetted contractors
Open source: source code available for a community to access. A collaborative effort by which software developers create a product such as Linux: the developers often volunteer their time
- a mobile network is a communication network where the last link is wireless. The network is distributed over land areas called cells, each served by at least one fixed-location transceiver but more normally three cell sites or base transceiver stations. These base stations provide the cell with the network coverage which can be used for transmission of voice, data and others. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. Know the difference between a vertical and horizontal market application.
Horizontal- market application: software that provides capabilities common across all organizations and industries: examples include word processors, graphics programs, spreadsheets, and presentation programs
Vertical-market application: software that serves the needs of a specific industry. Examples of such programs are those used by dental offices to schedule appointments and bill patients, those used by auto mechanics to keep track of customer data and customers’ automobile repairs, and those used by parts warehouses to track inventory, purchases, and sales
