What is Active Directory? 

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.

 

 

 

What is SNMP?

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.

 

 

 What is 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. Since Windows 2000, WMI comes preinstalled with Windows operating systems.

WMI is the Microsoft implementation of the Web-Based Enterprise Management (WBEM), which is managed by the Distributed Management Task Force (DMTF). WBEM sets standards to allow access to data from non-uniform technologies and devices across a standardized architecture. WBEM uses the Common Information Model (CIM) as the schema for defining information about objects.hich both stores files and accepts print jobs from clients and then sends them on to a network-attached printer.

 

 

 

What is 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.

REST as a network architecture was first documented by Roy Fielding in his doctoral thesis titled Architectural Styles and the Design of Network-based Software Architectures, published in 2000. REST allows clients to interact with data stored on a server, without having any prior knowledge of the server or what exists on it.

 

 

What is VPN?

A virtual private network extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network

The VPN itself simply acts like a network interface to the client and is transparent the operating system, applications, and users accessing the VPN network. Therefore, applications, messages, and users can all use the connection normally without any need to understand how the VPN operates.

 

 

 

 

What is 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. It is primarily used for machine-to-machine (M2M) communication or Internet of Things types of connections.

 

 

 

 

 

 

What is packet sniffing?

Packet sniffing is the practice of gathering, collecting, and logging some or all packets that pass through a computer network, regardless of how the packet is addressed. In this way, every packet, or a defined subset of packets, may be gathered for further analysis. You as a network administrators can use the collected data for a wide variety of purposes like monitoring bandwidth and traffic.

A packet sniffer, sometimes called a packet analyzer, is composed of two main parts. First, a network adapter that connects the sniffer to the existing network. Second, software that provides a way to log, see, or analyze the data collected by the device.

 

 

What is CCTV?

closed-circuit television

CCTV stands for closed-circuit television and is commonly known as video surveillance. “Closed-circuit” means broadcasts are usually transmitted to a limited (closed) number of monitors, unlike “regular” TV, which is broadcast to the public at large. CCTV networks are commonly used to detect and deter criminal activities, and record traffic infractions, but they have other uses.

CCTV technology was first developed in 1942 by German scientists to monitor the launch of V2 rockets. It was later used by American scientists during the testing of the atomic bomb.

What is TLS?

TLS is short for Transport Layer Security. It is a form of security protocol that offers high levels of privacy, as well as data integrity when it comes to communication using networks and the internet. TLS is the standard for use in secure web applications and websites around the world since its introduction in 1999. It is the successor and replacement for the older SSL (Secure Socket Layer) system. It is often still referred to as SSL when it comes to businesses explaining the safety features they have in place for their websites and data security. While TLS is most commonly associated with browsing the web, it is also used for a range of other forms of applications where security is a requirement, such as instant messaging, email, VoIP networks, and similar functionalities. Its widespread use and development have provided additional security, privacy, and better performance – especially since the release of TLS 1.3, the most recent version of the TLS Protocol. TLS is used actively in the majority of browsers, as indicated by the padlock symbol, which suggests encryption of the sites you are viewing. HTTPS is designated as the more protected form of websites, thanks to its use of the TLS protocol to protect visitors whenever data is exchanged.

 

 What is IIoT?

I saw a recent magazine article outlining six steps to take to implement the Industrial Internet of Things (IIoT). It was mostly political – form a team, get buy-in from a C-level executive, etc. It’s not that I think the political approach is not valuable, but most of us live in a technical world. So here are the technical steps to the IIoT.

 

What is a server?

  Cloud Computing

What are some of the most effective ways to use cloud computing to achieve business goals?

IPv6

IPv6 is the newest version of internet protocol formulated by the IETF, which helps identify and local endpoint systems on a computer network and route online traffic while addressing the problem of IPv4 address depletion due to prolonged internet use worldwide
