Information Systems Flashcards

Flashcards based on Information Systems lecture notes.

Hardware

Physical components of a computer system that can be seen and touched.

Software

Applications that run on hardware, such as Outlook and Word.

Data

Information collected and produced in the software and stored on the hardware.

Procedures

SAAS

Software as a Service, accessible via web browser and priced on a pay-per-use basis.

PAAS

Platform as a Service: Development and deployment environment.

IAAS

Infrastructure as a Service: Servers, storage, and networking, commonly used for business continuity and disaster recovery.

Qualitative Data: Nominal

Data that cannot be measured through numerical units (e.g., red, yellow, blue).

Qualitative Data: Ordinal

Quantitative Data: Discrete

Integers or whole numbers.

Quantitative Data: Continuous

Fractional numbers with a numeric value.

Application Programming Interface (API)

Software intermediary that allows two applications to communicate with each other.

Open APIs

APIs that any developer can access.

Partner APIs

APIs that only authorized developers may access.

Internal APIs

APIs that only internal teams can access.

Composite APIs

APIs that combine multiple APIs.

REST

Collection of guidelines for lightweight, scalable web APIs.

SOAP

A stricter protocol for more secure APIs.

RPC

A protocol for invoking processes.
