As one would expect, advanced IP addressing and routing protocol design encompasses a large amount of detail that has already filled a number of books on routing protocols and networking best practices. This section reviews the importance of IP address planning and selection and the importance of IP address summarization. It also discusses some applications of summary addressing. IP Address Planning as a Foundation Structured and modular cabling plant and network infrastructures are ideal for a good design with low maintenance and upgrade costs.
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.
Algorithm A set of rules and decision structures for actions in a specifically defined set of circumstances. Alias A file whose sole purpose is to represent another file. Alignment errors are usually caused by frame damage due to collisions.
All-rings Explorer Packet See all-routes explorer packet. All-routes Explorer Explorer Packet packet that traverses an entire SRB network, following all possible paths to a specific destination. Sometimes called all-rings explorer packet, See also explorer packet, local explorer packet, and spanning explorer packet.
AppleTalk Low Overhead Encapsulation. Alphanumeric Referring to a group of printable characters that includes the letters of the alphabet in both upper and lower case, the numerals plus a limited group of additional symbols and punctuation marks.
Modulation technique whereby information is conveyed through the amplitude of the carrier signal. Ambient Referring to a set of conditions that exist independently of the system of interest.
AMI Alternate mark inversion. Line-code type used on T1 and E1 circuits. In AMI, zeros are represented by 01 during each bit cell, and ones are represented by 11 or 00, alternately, during each bit cell. AMI requires that the sending device maintain ones density.
Ones density is not maintained independent of the data stream. Sometimes called binary coded alternate mark inversion. See also ones density. A standard unit of measurement for electrical current flow. Amplitude In the terminology of wave motion, the height of the wave.
Amplitude is usually measured from a reference point of 0. In electrical waves, amplitude is typically expressed in volts. Analog Referring to a system or component that uses a system of measurement, response or storage in which values are expressed a s a magnitude using a continuous scale of measurement.
Analog Transmission Signal transmission over wires or through the air in which information is conveyed through variation of some combination of signal amplitude, frequency, and phase.
Anomaly An unusual instance or circumstance. The principle group in the US. A system of higher- level protocols used for the transmission of data and authentication between applications.
APaRT recognizes specific data link layer encapsulation packet types and, when these packet types are transferred from one medium to another, translates them into the native format of the destination device.
A set of tools and procedures provided by the programmer of an application so that other programmers can control, exchange data with, or extend the functionality of an application.
Apollo Domain Proprietary network protocol suite developed by Apollo Computer for communication on proprietary Apollo networks. IBM SNA system software that allows high-speed communication between programs on different computers in a distributed computing environment.
APPC establishes and tears down connections between communicating programs, and consists of two interfaces, a programming interface and a data-exchange interface. The former replies to requests from programs requiring communication; the latter establishes sessions between programs.
See also LU 6. AppleScript A programming language that can call tasks within Macintosh applications.
Application An independently executable set of algorithms and data structures that perform a specific set of functions.Figure 1: RP3 interface of RF and baseband modules. There exists a maximum of K pairs of unidirectional links toward RP 18 Figure 2: Full mesh connecting two .
ACDI: Asynchronous Communications Device Interface: A software device that permits asynchronous transmission, a way of transmitting data in which one character is sent at a time, and there may be uneven amounts of time between characters.
Assignment 1 How Networks communicate. One of Networking’s primary functions is to be able to communicate to one and another and this would include a range of templates to work from which would do their own roles, these are called Topologies.
there are a few types of Topologies which would work differently from one and another such as the Star topology and the Bus Topology. Unit 3. Assignment 1: network topologies | June 30 | Unit 3 | | Star: In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection.
In Star topology every node (computer workstation or any other peripheral) is . Question 1.
Explanation. CSMA/CD stands for Carrier Sense Multiple Access with Collision lausannecongress2018.com an Ethernet LAN, before transmitting, a computer first listens to the network media. If the media is idle, the computer sends its data.
Layer 2 Domain. The access and distribution layers form the boundary for the Layer 2 domain of the building block network. This is an area where the Spanning Tree Protocol (STP) plays a critical role.
