IT Explained

We at Paessler use IT-related terms constantly and we are very much aware of the “The Imposter Syndrome” in IT
when professionals continue using terminology they might not even understand themselves.

“IT explained” therefore isn’t a book review on Stephen King’s great novel, but the summary and explanation of tricky,
sometimes misinterpreted terms of information technology.

OPC UA

OPC UA stands for OPC Unified Architecture. It is an extensible, platform-independent standard that enables the secure exchange of information in industrial systems.

HCI

HCI stands for hyperconverged infrastructure. HCI is made up of virtual networking, administration, and storage and computing components that share resources.

IIoT

IIoT stands for the Industrial Internet of Things and refers to a network of connected devices in the industrial sector. It is a subset of the Internet of Things (IoT) .

TLS

TLS stands for Transport Layer Security. It is a cryptographic protocol used to secure data sent over a network, like internet traffic. TLS secures the transmission and delivery of data.

CCTV stands for closed-circuit television and is commonly known as video surveillance.CCTV networks are commonly used to detect and deter criminal activities, and record traffic infractions, but they have other uses.

Packet Sniffing

Packet sniffing is the practice of gathering, collecting, and logging some or all packets that pass through a computer network.

MQTT

MQTT stands for Message Queuing Telemetry Transport. It is a lightweight messaging protocol for use in cases where clients need a small code footprint and are connected to unreliable networks or networks with limited bandwidth resources.

Retrofitting

Retrofitting is updating or adding equipment, sensors, or services to existing hardware so that it is able to make use of new technologies.

VPN

VPN stands for Virtual Private Network. It is a method by which two end-points create a single, private connection, or tunnel, while using a larger network infrastructure such as the internet or WAN.

REST

REST is an architecture style definition applied to networked applications. It exists as a series of constraints applied to the implementation of network components, enabling uniform interface semantics, rather than application-specific implementations and syntax.

LPWA

LPWA stands for Low-Power Wide-Area and serves as a generic term for any network designed to communicate wirelessly with lower power than other networks such as cellular, satellite, or WiFi.

WMI

WMI stands for Windows Management Instrumentation. Designed by Microsoft, it is an infrastructure for the standardized management of data and information that is device independent.

Server

A server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In theory, whenever computers share resources with client machines they are considered servers.

SNMP

SNMP stands for Simple Network Monitoring Protocol. It is a protocol for management information transfer in networks, for use in LANs especially.

Active Directory

Active Directory (AD) is a directory service created by Microsoft for use in a Windows Server environment.

Bandwidth

Bandwidth is the amount of data that can be transferred from one point to another within a network in a specific amount of time. It is measured in bits per second.

Virtualization

Virtualization is the process of creating a virtual version of something like computer hardware. It allows to create multiple environments from a single system

IP address

An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network.

Ping

Ping is a command-line utility to test the reachability of a networked device. It sends a echo request and expects an echo reply from the target host.

Syslog

Syslog is a protocol used to send system log or event messages to a specific server. It is primarily used to collect device logs in a central location...

NetFlow

NetFlow is a network monitoring protocol that allows a NetFlow enabled device to collect, aggregate, and export all passing traffic data...
