Networking

Remote Direct Memory Access (RDMA) is a technology that enables two networked computers to exchange data in main memory without relying on the processor, cache or operating system of either computer.

A chatty protocol is an application or routing protocol requiring a client or server to wait for an acknowledgment before transmitting data again.

Email archiving is a systematic approach to saving and protecting the data contained in emails to enable fast retrieval.

On the Internet, @ (pronounced "at" or "at sign" or "address sign") is the symbol in an e-mail address that separates the name of the user from the user's Internet address, as in this hypothetical e-mail address example: [email protected]

MIME, or Multipurpose Internet Mail Extensions, is an extension of the original email protocol.

Internet metering is a service model in which an internet service provider (ISP) keeps track of bandwidth use and charges users accordingly.

Fifth-generation wireless (5G) is the latest iteration of cellular technology. Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances, 5G wireless signals are transmitted through large numbers of small cell stations located on places like light poles or building roofs.

Fog computing is a decentralized computing infrastructure in which data, compute, storage and applications are located somewhere between the data source and the cloud.

Ambient intelligence (AmI) is the element of a pervasive computing environment that enables it to interact with and respond appropriately to the humans in that environment.

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

A fixed-length subnet mask (FLSM) refers to a type of enterprise or provider networking where a block of IP addresses is divided into multiple subnets of equal length (i.e., an equal number of IP addresses).

A virtual network adapter is software that operates like a physical network adapter within the host operating system (OS) or through an application installed on the endpoint or server.

10BASE-T is an Ethernet standard for local area networks and one of several physical media specified in the Institute of Electrical and Electronics Engineers (IEEE) 802.3 standard.

A host bus adapter (HBA) is a circuit board or integrated circuit adapter that connects a host system, such as a server, to a storage or network device.

Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time.

The Seebeck effect is a phenomenon in which a temperature difference between two dissimilar electrical conductors or semiconductors produces a voltage difference between the two substances.

A HELLO packet is a special data packet (message) that is sent out periodically from a router to establish and confirm network adjacency relationships to other routers in the Open Shortest Path First (OSPF) communications protocol.

Remote Procedure Call (RPC) is a protocol that one program can use to request a service from a program located in another computer on a network without having to understand the network's details.

Non-broadcast multiple access (NBMA) is one of four network types in the Open Shortest Path First (OSPF) communications protocol.

Windows Server Update Services (WSUS) is a Windows server role that can plan, manage and deploy updates, patches and hotfixes for Windows servers, client operating systems and other Microsoft software.

A chatty protocol is an application or routing protocol requiring a client or server to wait for an acknowledgment before transmitting data again.

IDSL is a hybrid of a digital subscriber line (DSL) and integrated services digital network (ISDN) technology that transmits data slightly faster than ISDN but much slower than most DSL services.

A HELLO packet is a special data packet (message) that is sent out periodically from a router to establish and confirm network adjacency relationships to other routers in the Open Shortest Path First (OSPF) communications protocol.

Route summarization -- also known as route aggregation -- is a method to minimize the number of routing tables in an Internet Protocol (IP) network.

Variable Length Subnet Mask (VLSM) is a subnet -- a segmented piece of a larger network -- design strategy where all subnet masks can have varying sizes.

In physics, charge, also known as electric charge, electrical charge, or electrostatic charge and symbolized q, is a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons.

A carbon offset is a credit that a person or organization can buy to decrease its carbon footprint.

A charge-coupled device (CCD) is a light-sensitive integrated circuit that captures images by converting photons to electrons.

A call center is a centralized department that handles inbound and outbound calls from current and potential customers.

A satellite is any object that orbits something else, as, for example, the Earth orbits the sun.

VoIP caller ID (voice over Internet Protocol caller identification) is a caller ID application for VoIP phones that works in the same way as caller ID on a conventional telephone line.

VoIP caller ID (voice over Internet Protocol caller identification) is a caller ID application for VoIP phones that works in the same way as caller ID on a conventional telephone line.

Jitter is any deviation in, or displacement of, the signal pulses in a high-frequency digital signal.

VoIP (voice over Internet Protocol) is the transmission of voice and multimedia content over an internet connection.

Session Initiation Protocol trunking is a service offered by a communications service provider that uses the protocol to provision voice over IP connectivity between an on-premises phone system and the public switched telephone network.

A virtual private network (VPN) is a service that creates a safe, encrypted online connection.

Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b.

A harmonic is a wave or signal whose frequency is an integral (whole number) multiple of the frequency of the same reference signal or wave.

A satellite is any object that orbits something else, as, for example, the Earth orbits the sun.

The GPS (Global Positioning System) is a 'constellation' of approximately 30 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location.
