BCIS 2610 Exam 1 Study Guide

What is Moore’s Law?

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

What is Metcalfe’s Law?

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.

What is Kryder’s Law?

- 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

departments involved

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

RAM (memory): instant memory, always in use as a temporary location to execute  instructions from your computer

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
