“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.

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 is updating or adding equipment, sensors, or services to existing hardware so that it is able to make use of new technologies.
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 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 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 stands for Windows Management Instrumentation. Designed by Microsoft, it is an infrastructure for the standardized management of data and information that is device independent.
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 stands for Simple Network Monitoring Protocol. It is a protocol for management information transfer in networks, for use in LANs especially.
Active Directory (AD) is a directory service created by Microsoft for use in a Windows Server environment.
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 is the process of creating a virtual version of something like computer hardware. It allows to create multiple environments from a single system
An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network.
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 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 is a network monitoring protocol that allows a NetFlow enabled device to collect, aggregate, and export all passing traffic data...
