Washington K-20 Network is a wide area network providing educational Internet access in the U.S. state of Washington for schools and educational service districts, colleges and community colleges, and libraries.
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.
The Washington Assessment of Student Learning ( WASL) was a standardized educational assessment system given as the primary assessment in the state of Washington from spring 1997 to summer 2009. The WASL was also used as a high school graduation examination beginning in the spring of 2006 and ending in 2009. It has been replaced by the High School Proficiency Exam (HSPE), the Measurements of ...
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface. Packet Tracer makes use of a drag and drop user ...
In telecommunications, packet switching is a method of grouping data into short messages in fixed format, i.e. packets, that are transmitted over a digital network. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an ...
OSI had two major components: an abstract model of networking, called the Basic Reference Model or seven-layer model, and a set of specific protocols. The OSI reference model was a major advance in the standardisation of network concepts.
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.
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 ...
