1.13 Convergence – In the telecommunications industry‚ convergence refers to the integration of voice‚ internet‚ broadcasting‚ and other telephony servers into one mega-industry from their traditionally separate industries. Companies such as Telstra are an excellent example of this‚ as Telstra now offers an abundance of products such as‚ Fixed Phone‚ Mobile Phone‚ Dialup Internet‚ Broadband Internet‚ Wireless Internet‚ TV‚ Music‚ Tickets‚ and more. Incentives are given to “bundle” services with the

ECS 152A Fall 2013: Assignment 1 - Solution Date Assigned: 10/2/2013 Date Due: 10/9/2013 Problem 1 Consider two hosts A and B connected by a single link of rate R bps. Suppose the two hosts are separated by m meters‚ and suppose the propagation speed along the link is s meters/sec. Suppose host A begins to transmit a packet of size L bits at time t = 0. 1. Let dtrans denote the time to transmit the packet. At time t = dtrans where is the last bit of the packet? 2. Let dprop denote the propagation

Computer Science Notes - Networking (3.1.6 -3.1.11) Protocol A protocol is basically a set of rules and regulations that govern how data is to be transmitted across a network. It defines the regulations regarding software as well as hardware. To enable two/more devices to communicate‚ they must follow the same protocol - an agreed format for transmission of data between devices. The protocol determines things such as: Type of error checking to be used‚ data compression methods‚ etc. Packet

Circuit Switching and Packet Switching IT 242 May 4‚ 2014 Circuit Switching and Packet Switching Circuit switching‚ although more reliable than packet-switching because it is able to get your message across without any hiccups‚ is old and expensive. Circuit switching is based on having a dedicated line or session between two stations and thus‚ you are able to get the full message across without congestion or interruptions. An example of circuit switching hardware is PBX. In addition

ARPANET grew during the 1970’s as more and more supercomputer stations were added. The users of ARPANET had changed the high speed network to an electronic post office. Scientists and researchers used ARPANET to collaborate on projects and to trade notes. Eventually‚ people used ARPANET for leisure activities such as

Defense issued a twenty thousand dollar contract on December 6‚ 1967 for the purpose of studying the design and specification of a computer network (Internet History from ARPANET to Broadband‚ 2007). It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 and was first known as the ARPANet (Computer history museum‚ 2006). The ARPA laid the groundwork which later became the internet. By 1992 the Internet has one million hosts (Ganna‚ 2006). Through the years

Through the next couple years there were talks of about how this network could come into the cooperate world and in 1969 researchers at four US campuses create the first hosts of the ARPANET‚ connecting Stanford Research Institute‚ UCLA‚ UC Santa Barbara‚ and the University of Utah. The ARPANET is a success from the very beginning. Although originally
