Packet internet groper (PING)
Packet internet groper (PING): A utility used to test the reachability and round-trip time of a network host. PING is commonly used by IT professionals to diagnose network connectivity issues and monitor the performance of a network. For example, a user may use PING to check if a website is online, measure the response time […]
Packet Switching
Packet Switching: A mode of data transmission where a message is broken into several packets. Each packet is then sent individually, possibly via different routes, and reassembled at the destination. This method is efficient and robust, allowing for rerouting of packets if a connection is lost or if there is a more efficient route. In […]
Packet
Packet: A unit of data routed between an origin and a destination in a network. Packets are the basic units that carry data in network communications, enabling information to be segmented, transmitted, routed, and received across diverse systems and devices. The security of packet transmission can be enhanced with various mechanisms like encryption to protect […]
Peer-to-peer (P2P)
Peer-to-peer (P2P): A type of network structure where each computer has the same capabilities and functions, allowing it to act as both a client and a server. It is used in networking to allow for decentralized communication and data sharing. Examples include BitTorrent and Skype.
OSI Reference Model
OSI Reference Model: An abstract description for layered network protocol design. It consists of seven separate but related layers, each defining a part of the process of moving information across a network. This layering concept allows for the separation of concerns, facilitating interoperability and standardization of network protocols within their respective layers.
Out-of-band (OOB)
Out-of-band (OOB): A method of transmitting information using a separate communication channel from the primary data channel. It is commonly used in networking and cybersecurity to provide alternative access to systems and networks in case of failures or other emergency situations. Examples of OOB communication include dial-up modems and satellite links.
