WAN Technologies - POINT–TO-POINT

WAN technologies are based on serial transmission at the physical layer. This means that the bits of a frame are transmitted one at a time over the physical medium. The bits that make up the Layer 2 frame are signaled one at a time by physical layer processes onto the physical medium. The signaling methods include Nonreturn to Zero Level (NRZ-L), High Density Binary 3, (HDB3), and Alternative Mark Inversion (AMI). These are examples of...

Router and Routing Basics - Routing and Routing protocols

Routing is the process that a router uses to forward packets toward the destination network. A router makes decisions based upon the destination IP address of a packet. All devices along the way use the destination IP address to point the packet in the correct direction so that the packet eventually arrives at its destination. In order to make the correct decisions, routers must learn the direction to remote networks. When routers use dynamic...

Networking basics - CABLING LANS AND WANS

Various symbols are used to represent media types. Token Ring is represented by a circle. Fiber Distributed Data Interface (FDDI) is represented by two concentric circles and the Ethernet symbol is represented by a straight line. Serial connections are represented by a lightning bolt. Each computer network can be built with many different media types. The function of media is to carry a flow of information through a LAN. Wireless LANs use...

Networking basics - Ethernet Fundamentals

Most of the traffic on the Internet originates and ends with Ethernet connections. From its beginning in the 1970s, Ethernet has evolved to meet the increasing demand for high speed LANs. When a new media was produced, such as optical fiber, Ethernet adapted to take advantage of the superior bandwidth and low error rate that fiber offers. Now, the same protocol that transported data at 3 Mbps in 1973 is carrying data at 10 Gbps. The success...
