information systems ch 13 quiz review

programming language

Provides the standards, syntax, statements, and instructions for writing computer software.

Packaged enterprise systems can:

all of the above

waterfall

A relatively linear sequential approach to software development (and other projects). Benefits include surfacing requirements up front and creating a blueprint to follow throughout a project. Often criticized for being too rigid, slow, and demanding project forethought that's tough to completely identify early on.

service-oriented

A robust set of Web services built around an organization's processes and procedures.

supply chain management (SCM)

Systems that can help a firm manage aspects of its value chain, from the flow of raw materials into the firm, through delivery of finished products and services at the point-of-consumption.

Feature creep can be defined as:

an expansion of the scope of a project.

A(n) _____ is an application for programmers, which includes a text editor, a debugger for sleuthing out errors, and other useful programming tools.

integrated development environment

capability maturity model

A process-improvement approach (useful for but not limited to software engineering projects) that can assist in assessing the maturity, quality, and development of certain organizational business processes, and suggest steps for their improvement.

server

A program that fulfills the requests of a client.

Java

A programming language, initially developed by Sun Microsystems, designed to provide true platform independence ("write once, run anywhere") for application developers. In most cases, Java apps are developed to be executed by a Java Virtual Machine—an interpreting layer that translates code as it executes, into the format required by the operating system and microprocessor. Without Java, application developers have to write and compile software to execute natively by a specific operating system / microprocessor combination (e.g., Windows/Intel, Linux PowerPC, Mac/Intel, Linux/Intel).

EDI (electronic data interchange)

A set of standards for exchanging messages containing formatted data between computer applications.

enterprise resource planning (ERP)

A software package that integrates the many functions (accounting, finance, inventory management, human resources, etc.) of a business.

software package

A software product offered commercially by a third party.

client

A software program that makes requests of a server program.

extensible markup

A tagging language that can be used to identify data fields made available for use by other applications. Most APIs and Web services send messages where the data exchanged is wrapped in identifying XML tags.

applications

Includes desktop applications, enterprise software, utilities, and other programs that perform specific tasks for users and organizations.

JSON

JavaScript Object Notation (JSON)—a popular data interchange format, JSON is a technology standard often used to format data when being sent or received via APIs.

interpreted

Languages where each line of written code is converted (by a software program, called an "interpreter") for execution at run-time. Most scripting languages are interpreted languages. Many programmers also write Java applications to be interpreted by the Java Virtual Machine.

platforms

Products and services that allow for the development and integration of software products and other complementary goods. Windows, iOS, Android, and the standards that allow users to create Facebook apps are all platforms.

platforms

Products and services that allow for the development and integration of software products and other complementary goods. Windows, the iPhone, the Wii, and the standards that allow users to create Facebook apps are all platforms.

Rails, Django, AngularJS, and ASP.NET are examples of ____________.

Programming frameworks

APIs

Programming hooks, or guidelines, published by firms that tell other programs how to get a service to perform a task such as send or receive data. For example, Amazon.com provides APIs to let developers write their own applications and websites that can send the firm orders.

scripting languages

Programming tool that executes within an application. Scripting languages are interpreted within their applications, rather than compiled to run directly by a microprocessor.

database management system (DBMS)

Sometimes referred to as database software; software for creating, maintaining, and manipulating data.

embedded systems

Special-purpose software designed and included inside physical products (often on firmware). Embedded systems help make devices "smarter," sharing usage information, helping diagnose problems, indicating maintenance schedules, providing alerts, or enabling devices to take orders from other systems.

computer hardware

The physical components of information technology, which can include the computer itself plus peripherals such as storage devices, input devices like the mouse and keyboard, output devices like monitors and printers, networking equipment, and so on.

operating system

The software that controls the computer hardware and establishes standards for developing and executing applications.

Firmware is used to refer to:

a device's control programs stored on nonvolatile memory chips.

A process-improvement approach that can assist in assessing the maturity, quality, and development of certain organizational business processes, and suggest steps for their improvement is known as:

capability maturity model integration.

An organization is said to be _____ if its systems operate within required legal constraints, and industry and organizational obligations.

compliant

Operating systems are designed to give programmers a common set of commands to consistently interact with the hardware. These commands make a programmer's job easier by:

making it faster to write software while minimizing the possibility of errors in code.

A(n) _____ is software that controls computer hardware and establishes standards for developing and executing applications.

operating system

Products and services that allow for the development and integration of software products and other complementary goods are known as _____.

platforms

The costs associated with the design, development, testing, implementation, documentation, training and maintenance of a software system are collectively referred to as:

total cost of ownership.

While the Health.gov failure was large and public, it was by no means an anomaly. Research firm the Standish Group estimates that in the past ten years, some ____ percent of large federal information technology projects were unsuccessful

94

distributed computing

A form of computing where systems in different locations communicate and collaborate to complete a task.

Which of the following has become a dominant software development methodology?

Agile development

integrated development

An application that includes an editor (a sort of programmer's word processor), debugger, and compiler, among other tools.

scrum

An approach to organizing and managing agile projects that breaks deliverables into "sprints" delivered in one to six week increments by teams of less than ten. Scrum defines functions (roles) for management and development, meetings (ceremonies), and how the process is documented and tracked (artifacts).

total cost of ownership

An economic measure of the full cost of owning a product (typically computing hardware and/or software). TCO includes direct costs such as purchase price, plus indirect costs such as training, support, and maintenance.

feature creep

An expansion of the scope of a project.

desktop software

Applications installed on a personal computer, typically supporting tasks performed by a single user.

enterprise software

Applications that address the needs of multiple users throughout an organization or work group.

_____ is the term used to represent the physical components of information technology.

Computer hardware

_______________ are methods to divide tasks related to software creation and deployment up into tasks targeted at building better products

Software development methodologies

firmware

Software stored on nonvolatile memory chips (as opposed to being stored on devices such as hard drives or removable discs). Despite the seemingly permanent nature of firmware, many products allow for firmware to be upgraded online or by connecting to another device.

application server

Software that houses and serves business logic for use (and reuse) by multiple applications.

software development

Sometimes also referred to as the SDLC or software development life cycle—methods to divide tasks related to software creation and deployment up into tasks targeted at building better products with stronger product management guidelines and techniques.

compile

Step in which program code written in a language that humans can more easily understand, is then converted into a form (expressed in patterns of ones and zeros) that can be understood and executed by a microprocessor. Programmers using conventional programming languages must compile their software before making it available for execution.

_____ systems help a firm manage aspects of its value chain, from the flow of raw materials into the firm through delivery of finished products, and services at the point-of-consumption.
