Ethernet and ATM: Which Will Prevail? Abstract Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas
distant diagnosis, video conferences, and many other applications have popped up one after another in recent years. They all require that the same data be sent to multiple recipients. This operation is called multicasting. Introduction: Asynchronous Transfer Mode (ATM) is the mostly implemented in high speed networks. ATM is the transmission system for CCITT's next-generation ISDN, Broadband ISDN (B-ISDN). B-ISDN is designed to provide subscriber communication services over a wide range of bit
Frame Relay and Leased Lines In networking there are many options in having data transferred from one location to another. Two of which include frame relay and leased lines. Frame relay is a communication method that transfers data by dividing information into packets and sending them over a virtual network. Frame relay is a difficult process to understand and to accomplish. Leased lines, however, is the permanent connection between two stations. Leased lines are simpler to understand and
Introduction The purpose of this papers it to examine in detail the operation of one of the wide area network that we discussed in class. This paper discusses the difference between frame relay networks and other point to point networks, advantages, addressing schemes, and different protocols supported. The paper will explain virtual circuits briefly before moving to its other characteristics because they are the key to understanding frame relay concept in general. Other than virtual circuits, we
25 years later. After all, in how many businesses could you get away with charging money for a service you once gave away, without markedly improving the quality of the service (even the latest ATMs can do little more than the "accept deposits", "transfer money between accounts", and "withdraw up to $300" that the ATMs of the late 1970s could do) . . . and despite the price of the underlying technology having dropped to a fraction of its original cost? So much for making money the old-fashioned way
Many years’ people have been trying to figure out who actually invented the ATM ideas or machines. There are six developers’ that are being tossed around by past researchers of who was the originator of this exciting technology. The six developer’s names are as follows; Luther George Simjian, John Shepherd-Barron, James Goodfellow, Don Wetzel, John D. White and Jairus Larson. Luther George Simjian was famous for the earlier development creation of ATM science in the past1930’s that was not a solid
Introduction When electronic devices transfer information to another electronic device, the devices need to know when data flow is beginning and ending. This is done with signals for synchronization.i This report will describe the two forms of data communications in terms of the physical interfaces and modes of operation. It will describe the features of data communications equipment in relation to synchronous and asynchronous communication including modems, network terminating units and sending
parallel and synchronous or asynchronous. The bus lets the different components communicate with each other by allowing information to flow between units and devices. Address lines show the source and end-point of the data on the data lines. Control lines are used in starting the bus protocol. Normally there are lines
Synchronous and Asynchronous mode: In telecommunication signaling within a network or between networks, synchronous signals are those that occur at the same clock rate when all clocks are based on a single reference clock. Synchronous communication requires that each end of an exchange of communication respond in turn without initiating a new communication. An asynchronous signal is one that is transmitted at a different clock rate than another signal. Asynchronous operation also means that a process
Transmission The purpose of this report is to describe some common data transmission terminology. This paper will discuss various data transmission (communication) protocols and how they are used in data communication. Synchronous and Asynchronous: Asynchronous serial transmission is a technique used in serial RS232 communication. The data is framed by a series of control bits known as the start bit, stop bit(s), parity bits and error checking bits. A transmit clock signal is used to clock the
INTRODUCTION Bluetooth is a wireless LAN technology designed to connect devices of different functions such as telephones, notebooks, computers (desktop and laptop), cameras, printers, and coffee makers. A Bluetooth LAN is an ad hoc network, which means that the network is formed spontaneously but sometimes it called gadgets and make a network called a piconet. The cable-free, or wireless, technology was initially conceived by Ericson in 1994, when the company began a study to investigate the feasibility
Message Passing Interface (MPI). In present day computing, while writing a parallel program for multi-core systems in distributed environment may deploy an approach where both shared and distributed memory models are used. Moreover an interoperable, asynchronous, and reliable working environment is required for programmers and researchers to build the HPC applications. This paper reviews the existing MPI implementations in Java. Several assessment parameters are identified to analyze the Java based MPI
Data Storage A computer contains various components such as input devices, output devices and CPU etc. We also use a number of other things such as instructions, program etc. All these are of no use if you do not have data to work with. Data can be stored only in the data storage unit. A storage is the essential component of any digital computer. It is required in a computer to store programs and the data processed by programs. Modern computers have incredible speed of processing because of fast
state in the design of initialization FSM is two AUTO REFRESH commands. These commands will refresh the DRAM memory. After the two refresh cycles, the initialization FSM will shift to i_MRS state. In this state LOAD MODE REGISTER command is generated to configure the SDRAM to a specific mode of operation.
Switched Networks Networks are getting more and more popular, and because of this more people use them, which slows them down. Networks in the future will need to have enough bandwidth to support applications, like multimedia, witch require larger bandwidth. Switching will change the way networks are designed. These changes will maximize productivity. Switching technology is increasing the efficiency and speed of networks. This technology
demultiplexed at the end of the transmission back into the original source, different data formats being transmitted at different data rates can be transmitted together. Specifically, Internet (IP) data, Synchronous Optical Network data (SONET), and asynchronous transfer mode (ATM) data can all be traveling at the same time within the optical fiber. Multiplexing, by definition, is the process where multiple channels are combined for transmission over a common transmission path. In the early 1990s, fiber could
Concepts of Circuit Switching Systems A circuit switched system is one where a dedicated connection must be set up between two nodes before they may communicate. For the duration of the communication, that connection may only be used by the same two nodes, and when the communication has ceased, the connection must be explicitly cancelled. A good example of this is the early telephone exchange systems, where one caller would ask the operator to connect them to a receiver, where the end result
station on the network. Communication between the network facility equipment and the remote computer is accomplished through a data link. The only difference between a remote user and workstations connected directly to the network is slower data transfer speeds. Remote Access is also useful when you want to connect local office computers with corporate networks. This allows the business to share resources as if all computers are connected to the same LAN. Two common methods of providing this type

Increasing demand for fiber optic transmission systems like asynchronous transfer mode (ATM), synchronous optical networks (SONET) and most wireless communications systems, provide significant opportunities for ADCT. The company currently focuses on enabling communications service providers to deliver high-speed services to
