OFDM
OFDMA (orthogonal frequency-division multiple access), a technology in Wi-Fi 6, improves wireless network performance by establishing independently modulating subcarriers within frequencies. This approach allows simultaneous transmissions to and from multiple clients.
split horizon
Split horizon is a method used by distance vector protocols to prevent network routing loops. The basic principle is simple: Never send routing information back in the direction from which it was received
Split Domain Name System
Split Domain Name System (DNS) is a network configuration that separates a domain’s DNS server into two subdomains, one for internal use and one for external use. This configuration is used to direct internal and external traffic to different servers for the same domain, which can improve security, load balance, and resource optimization
NAC
Network Access Control (NAC) is a security solution that prevents unauthorized devices and users from accessing a network. It controls who can access what parts of a network and when, and ensures that only authorized devices and users can enter the network. NAC is applicable to both wired and wireless networks.
IEEE 802.3
IEEE 802.3 is a combination of standards and protocols defined by the Institute of Electrical and Electronics Engineers (IEEE). IEEE 802.3 is also known as the Ethernet standard and defines the physical and media access control (MAC) of the data link layer for wired Ethernet networks.
IEEE 802.11
802.11 is a standard that was developed by the Institute of Electrical and Electronic Engineers (IEEE). It is the original wireless specification. Extensions of the 802.11 standard were given the same number with a letter suffix.
intranet
An intranet is a computer network for sharing information, easier communication, collaboration tools, operational systems, and other computing services within an organization, usually to the exclusion of access by outsiders.
single collision domain
A single collision domain is a segment of a computer network where two or more devices cannot transmit data simultaneously without causing a collision.
hub and spoke topology
Hub and spoke topology is a network configuration where all nodes are connected to a central server, known as the hub, for data exchange and communication. It’s a straightforward and cost-effective way of routing and managing data on a network, with the central hub serving as a mediator for all communication, making it easier to configure security settings and monitor traffic. Hub and spoke topology is highly regarded for its simplicity, scalability, and enhanced security capabilities, making it a valuable choice for organizations.
Hub and spoke topology is a network configuration where all nodes are connected to a central server for data exchange and communication.
FDDI
The standard FDDI network is set up in a ring topology with two rings that transmit signals in opposite directions to a series of nodes. FDDI accommodates up to 500 nodes per dual-ring network and allows up to 2 kilometers between adjacent nodes.
Infrastructure mode
Infrastructure mode is a network topology that allows wireless devices to communicate with each other and with a wired network through a central access point, such as a wireless router.
Ad hoc mode
Ad hoc mode is a wireless network mode that allows devices to connect directly to each other without a centralized access point like a router. In ad hoc mode, each device acts as both a client and an access point, allowing them to communicate with any other device in range.creates p2p connections
Wireless mesh topology
Wireless mesh topology is a network architecture that connects devices through a mesh of radio nodes that communicate directly and dynamically with each other. The nodes work together to route data efficiently to and from clients.
IoT
An IoT network, or Internet of Things network, is a network of devices that are connected and exchange data with the cloud and other devices. IoT devices can be everyday objects like toothbrushes and vacuums, or more complex industrial tools.
Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks. In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres
RFID
Radio Frequency Identification (RFID) is a wireless technology that uses radio waves to identify and track objects, people, or animals. RFID systems are made up of two main components: a tag and a reader. The tag stores information that can be read by the reader, which can be done from a distance without line of sight.
NFC
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres
IR
Infrared is electromagnetic radiation with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with waves that are just longer than those of red light, so IR is invisible to the human eye
Z-Wave
home automation Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device,[2] allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers.[3][4] The Z-Wave brand and technology are owned by Silicon Labs. Over 300 companies involved in this technology are gathered within the Z-Wave Alliance.
ANT+
ANT+, introduced in 2004 as “the first ultra low power wireless standard”,[2] is an interoperability function that can be added to the base ANT protocol. This standardization allows the networking of nearby ANT+ devices to facilitate the open collection and interpretation of sensor data. For example, ANT+ enabled fitness monitoring devices such as heart-rate monitors, pedometers, speed monitors, and weight scales can all work together to assemble and track performance metrics
