PtP

The acronym PtP (Point-to-Point) indicates point-to-point radio links realized with wireless technologies. Differently, PtMP links connects a single source to multiple receivers: Point-to-MultiPoint.

SOC

The acronym SoC (System on Chip) describes particular integrated circuit that contain a whole system inside a single physical chip: the central processor, controllers (for instance, for peripheral units) and computing and I/O secondary units.

Edge Computing

The term Edge Computing refers, when used in the cloud-based infrastructure sphere, the set of devices and technologies that allows the computing of data at the edges of the network, whus maintaining the information close to the point where it0s generated, rather than moving it in remote datacenters or centralized systems

YAML

YAML is a file format used to serialize data offering an understandable formatting system. It was introduced in 2001 and uses rows indentation to define the information contained in the file.

Agentless

In the computing world, the term agentless refers to an operation that requires no human presence or the execution of a software process (daemon or service) in background. Usually there's another machine on the same network that performs certain operation to the destination computer.

JSON

JSON -JavaScript Object Notation- is a data exchange format. It's a language that can be easily read by a human but still is clear and promptly computable for a computer. Its basic structure comes from JavaScript, hence the name.

VCS

VCS stands for Version Control System, a software that can manage in a chronological order the evolution of structured information. In the IT world it refers to solutions dedicated to software code development, which usually requires a precise and detailed map of its history.

The most used and famous is Git.

SNMP

SNMP (Simple Network Management Protocol) is a standard network protocol, operating on ports 161 and 162, that allow to configure, manage and monitor network devices that support it. Its architecture has a system manager, an agent on the device to control and a number of managed objects, ie a set of elemental control information.

SysLog

SysLog is a simple network protocol that allows to send log information through computer networks. Designed in 1980, it's very used in the Unix and Linux world, but it's not quite used in the Windows sphere.

MDADM

MDADM is a Linux tool used to create, manage and monitor sofware RAID arrays (RAID 0, 1, 4, 5, 6 and 10). It's a free tool that can also be used aside from Linux, like raidtools developed by SUSE.

It also enables particular non-raid situations like Multipath and Failover with different "voluems" on the same physical disk in order to simulate fault situations.

Kubernetes

Kubernetes is a container orchestration tool. Developed mostly by Google, it saw a quick spread thanks to its capabilities of optimizing, improving and automating a large amount of manual management operations (deployment, deletion, creation, etc..).

ALOHA

ALOHA is a network protocol developed by the University of Hawaii in 1971 as a first demonstration of the operation of wireless networks on UHF frequencies. This protocol has laid the groundwork for the definition of the following Ethernet and WiFi protocols.

LTSC

The acronym LTSC (Long Term Servicing Channel), referring to the Microsoft world, characterizes the server products that are accompanied by a policy of releasing updates "slower" and with a cadence of two to three years between each major release. Compared to the SAC policy, the nomenclature of server operating systems is of the YYYY type, rather than YYMM (with Y = year and M = month).

SAC

The acronym SAC (Semi Annual Channel), referring to the Microsoft world, characterizes the server products that are accompanied by a policy of issuing of the semi-annual, customer-oriented policy that regularly require the latest features available. The service model is the same that characterizes the Windows 10 client operating system, with about six-month macro-relase and a YYMM type nomenclature (Y = Year, M = month).

Project Honolulu

Project Honolulu is the new Web platform (based on HTML 5) for centralized management of hosts and clusters in a Microsoft Windows Server environment. After being made available as a technical preview, in the next release Windows Server 2019 will be integrated in all respects.

WSL

The acronym WSL (Windows Subsystem for Linux) indicates the technology (a set of software components) introduced by Microsoft that allows you to run Linux commands inside a Windows  Server 2016 or 10.
This is a limited Linux environment and exclusively on the command line, so not a real Linux machine.

RIP

The acronym RIP (Routing Information Protocol) indicates a distance vector routing protocol, which as a path calculation metric uses the number of hops (jumps), up to a maximum of 15 units and to avoid loops.

Serverless Computing

The term Serverless Computing describes a cloud computing model where the provider deals with the distribution of computational resources, while the processing cost is calculated only on the basis of the consumption of the application in use, or on pre-purchased computing capacity.

Of course the computational power is provided by physical servers, but the term Serverless emphasizes that this aspect is completely transparent to the developer.

IoE

The acronym IoE (Internet of Everything) describes a context in which commonly used devices and products are all connected to the Internet and equipped with digital capabilities. In this ideal, in the future everything will be connected to the global network.

Snippet

The term Snippet indicates an extract of code that is short, reusable and easily integrated into larger codes. For example, a snippet can be composed of some lines of code that implement a certain function through parameters that are independent of the surrounding code.

Zero Day Exploit

A Zero Day Exploit describes a situation in which specific and unknown vulnerabilities are disclosed to the public simultaneously with the discovery of the same. This is a potentially very risky situation, because in the immediate future there are no patches or solutions that can secure the exploit.

InfiniBand

InfiniBand is an input / output architecture for the transmission of data between high performance systems composed of CPUs, processors and storage and characterized by high working frequencies, very low latencies and wide scalability.
IB architectures are realized through networks composed of switches with throughput higher than those typical of broadcast architectures like Ethernet. The maximum data transfer rate is around 40 Gbps.

DPO

The acronym DPO (Data Protection Officer) indicates the person or persons who, within the company context, are responsible for the correct application and compliance of the regulation on data processing (GDPR).

GDPR

The acronym GDPR indicates the new General Data Protection Regulation, which will come into force on 25 May 2018. This is the single and mandatory regulation for the whole European Union and that replaces the previous law on Privacy. The purpose of this provision is to restore the control of personal data to users and to intervene more precisely in case of data breach.
