What is IPS?
• An intrusion prevention system (IPS - Intrusion prevention system) is a network security tool (can be a hardware device or software) that continuously monitors malicious activity on the network and takes measures to prevent it. In particular, it generates reports, blocks or disables malicious actions if they actually occur.
What is IDS?
• Intrusion Detection System (IDS) — intrusion detection system is a software product or device designed to detect unauthorized and malicious activity on a computer network or on a separate host.
What is IGMP Snooping?
The traditional mode of unicast transmission over the network does not meet modern data transmission requirements, because instead it increases the load on the network and significantly consumes network bandwidth. IGMP Snooping was developed to solve this problem.
What is an intranet?
• Intranet — an internal network of a company or government agency that operates on the principle of the Internet, but is closed to unauthorized users. Simply put, this is the Internet in miniature, or the private Internet.
What is MAN?
• An urban Network (MAN) is a network that covers a large geographical area, connecting various local networks to form a larger network.
Multicast clients.
• Hosts that want to receive certain multicast data are called multicast clients. Multicast clients use services initiated (started) by client programs to send multicast data to groups.
What is Multicast?
There are 3 main methods of data transmission in IP networks: Unicast, Broadcast, Multicast.
What is Broadcast?
There are 3 main methods of data transmission in IP networks: Unicast, Broadcast, Multicast.
What is Unicast?
There are 3 main methods of data transmission in IP networks: Unicast, Broadcast, Multicast.
What is a SAN?
• SAN (Storage Area Network) is designed to consolidate the disk space of servers on specially allocated disk storage.
What is PAN?
• A personal network (PAN) is a network built "around" a person. PAN is a computer network that is used to transfer data between devices, such as computers, phones, tablets, etc. Personal networks can be used both for information interaction of individual devices with each other, and for connecting them to higher-level networks, for example, the global Internet, where one "primary" device takes assume the role of an Internet router.
Class addressing of IP networks.
• To simplify the classification of networks on the Internet, class addressing was used in the period from 1981 to 1993: IP addresses of the fourth version were divided into five categories:
What is WebRTC?
• WebRTC is a standard that describes the transmission of streaming audio data, video data and content between browsers or other applications that support it in real time. This technology allows you to turn the browser into a videoconferencing terminal. To start a conversation, just open the conference web page.
What is RTSP?
Robot couriers, drones, self-driving cars and other achievements of modern science and technology no longer seem like something from the world of fiction. They have become a familiar phenomenon for us. Built-in IP cameras allow them to “see” what is happening, and we can see the world through their “eyes". And what if we tell you that the vision of IP cameras is based on technology that has been around for more than 20 years?
What is a subnet?
• In one sense, a network is a group of devices under one control that can communicate with each other. Network also means a range of IP addresses - allocated or received from the registrar — for a specific physical network. For example, the selected private range is 10.0.0.0/8 or the range of external addresses received from the registrar is 192.0.2.0/24.
