Carrier-sense multiple access with collision avoidance ( CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". [1] [2] When they do transmit, nodes transmit their packet data in its ...
Flooding (computer networking) Flooding is used in computer network routing algorithms in which every incoming packet is sent through every outgoing link except the one it arrived on. [1] Flooding is used in bridging and in systems such as Usenet and peer-to-peer file sharing and as part of some routing protocols, including OSPF, DVMRP, and ...
Delay-tolerant networking. Delay-tolerant networking ( DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.
Multiplexing. Multiple low data rate signals are multiplexed over a single high-data-rate link, then demultiplexed at the other end. In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
CCNA (Cisco Certified Network Associate) is an entry-level information technology (IT) certification offered by Cisco Systems. CCNA certification is widely recognized in the IT industry as the foundational step for careers in IT positions and networking roles. Cisco exams routinely change in response to evolving IT trends.
A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter and physical network interface) is a computer hardware component that connects a computer to a computer network. Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
A Boolean circuit can be seen as a computer network: each gate is a computer that runs an extremely simple computer program. Similarly, a sorting network can be seen as a computer network: each comparator is a computer. Distributed algorithms in message-passing model. The algorithm designer only chooses the computer program.
The National Science Foundation Network ( NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) from 1985 to 1995 to promote advanced research and education networking in the United States. [1] The program created several nationwide backbone computer networks in support of these initiatives.
