Message notifying an operator or administrator of a network problem. See also event and trap. A-law is used primarily in European telephone networks and is similar to the North American mu-law standard. See also companding and mu-law.
Adobe Flash CS 5. A computer network is mainly classified into three types: LAN connects nodes over a short distance. WAN connects nodes over large geographical areas.
Network topology defines the way to group computers to form a network. In bus topology, the nodes are connected to a single backbone cable by a transceiver. In ring topology, each node is connected to the other to form a circular ring.
In star topology, each node is connected to a central switch or hub. The tree topology integrates multiple star topologies onto a bus. In mesh topology, each computer is connected to every other computer. Communication media are the cables used to connect various devices.
The communication media is classified into two types: In guided media, the computers are connected with each other through cables. The guided media is used for short distance data transmission.
The cables used for guided communication are twisted pair cable, coaxial cable and fiber optic cable. In unguided media, the computers are connected with each other through waves.
It is used for long distance data transmission.
Examples of unguided communication are micro wave, radio and satellite. Network devices are the components used to connect various computers and other electronic devices together to share the information. Network devices include modem, hub, switch, repeater, router, and gateway.
Network security provides freedom from risk. Some commonly used network security measures are authorisation, authentication, firewall and intrusion detection.These release notes describe the new features, improvements, and fixed issues in Network Configuration Manager (NCM) New features include Network Insight for .
NAT Basics Overview. NAT basics, also known as network address translation is an important part of the CCENT and CCNA certification exams. When NAT is implemented it allows a router to translate the source IPv4 address in the packet header as it crosses the router, changing the source address in the packet from one address to another.
Neural Smithing: Supervised Learning in Feedforward Artificial Neural Networks (A Bradford Book) [Russell Reed, Robert J MarksII] on kaja-net.com *FREE* shipping on qualifying offers. Artificial neural networks are nonlinear mapping systems whose structure is loosely based on principles observed in the nervous systems of humans and animals.
R ing topology, also known as Ring network, is a type of network topology where each node is exactly connected to two other nodes, forward and backward, thus forming a single continuous path for.

The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) beginning in to promote advanced research and education networking in the United States.
NSFNET was also the name given to several nationwide backbone computer networks that were constructed to support NSF's networking initiatives from .
