ERP

Enterprise Resource Planning
ERP refers to the practice of using BPM software to organize and automate all aspects of an operation with a single platform.

ETL

Extract, Transform, Load
ETL is the process of taking data from one database and adding it to another database — retrieving and manipulating data so that the receiving database can successfully handle the data.

FTP

File Transfer Protocol
FTP is a protocol used to transmit files between computers. FTP was first introduced in 1971. FTP does not provide encryption and is considered unsecured.

IPA

Intelligent Process Automation
The use of automation for business and IT processes to improve performance, provide orchestration and reduce or eliminate manual work and errors.

IA

Intelligent Automation
IA refers to IT automation tools that use machine learning or artificial intelligence to manage processes and infrastructure. IA tools are used to monitor IT operations environments and to resolve issues without human intervention.

IaaS

Infrastructure-as-a-Service
IaaS vendors provide cloud-based infrastructure often through a pay-as-you-go subscription model. IaaS hardware and software are owned by the service provider and can be hosted by the service provider or on-premises.

I&O

Infrastructure And Operations
I&O is a term used by Gartner to distinguish infrastructure and operations as a singular unit that is distinct from the rest of IT. In this context, I&O is responsible for managing the resources that developers, help desks and business teams rely on.

IoT

Internet of Things
IoT refers to a network of real-world devices that can interact and share data and information with other endpoints and remote data centers.

IDS

Intrusion Detection System
Also known as Intrusion Prevention System (IPS), this is either an application or device used to look for malicious activity on a network. Reports are typically sent through to a security information and event management system (SIEM) where it is reviewed and prioritized for legitimacy and threat level.

ITPA
