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.

Active Directory (AD) is a directory service for use in a Windows Server environment. It is a distributed, hierarchical database structure that shares infrastructure information for locating, securing, managing, and organizing computer and network resources including files, users, groups, peripherals and network devices.
Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps).
An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network.
LPWA stands for Low-Power Wide-Area. It does not refer to any one specific technology, but rather serves as a generic term for any network designed to communicate wirelessly with lower power than other networks such as cellular, satellite, or WiFi.
Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable.
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. There are many types of servers, including web servers, mail servers, and virtual servers.
SNMP stands for Simple Network Monitoring Protocol. It is a protocol for management information transfer in networks, for use in LANs especially, depending on the chosen version.
Syslog stands for System Logging Protocol and is a standard protocol used to send system log or event messages to a specific server, called a syslog server. It is primarily used to collect various device logs from several different machines in a central location for monitoring and review.
Virtualization is the process of creating a virtual version of something like computer hardware. It involves using specialized software to create a virtual or software-created version of a computing resource rather than the actual version of the same resource.
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. Since Windows 2000, WMI comes preinstalled with Windows operating systems.
