What is ATM? Essay -- ATM Asynchronous Transfer Mode Research Essays

What is automatic teller?Before the discussion of wireless automatic teller machine jackpot begin, the concept of ATM in general needs to be discussed. ATM, or by its more formal name Asynchronous Transfer Mode, is a basic packet-based networking system knowing for the simultaneous transmissions of voice, video, and selective information. In the mid 1980s, the study telecommunication companies decided that they needed a new network to palm the surge of video and data, along with voice, avocation being sent oer their existing networks. From this, the concept of ATM was born. From an increasing need to handle data traffic, which is inherently packet-based, as well as voice traffic, ATM was knowing to work as a packet-switched network. In a packet-switched network, all traffic is broken into small pieces, which are easier to transmit than one large globe of data. The problem with using this type of network design for ATM is that the grey-haired telephone network is circu it-switched, or in other words creates a physical direct connection between the source and destination during the transmission. ATM, therefore, is designed so that it can handle circuit-switched traffic on its packet-switched backbone. To accomplish this, ATM creates virtual(prenominal) circuit connections over the packet-based network between the source and the destination. These virtual circuit connections provision a set number of network resources dedicated to the connection between a specific source and destination, making it fall out to the old telephone network that a circuit connection is established. This allows an ATM network to guarantee the same or greater quality of helping for voice traffic as the old telephone network does, plot of land at the same time providing a much greater take of service for data and video tra... ... shifted to wireless IP-based systems. This shift is mostly delinquent to IPs built-in ability to handle transmission errors in the real m of wireless communications. Works Cited1) Ayanoglu, E., K.Y. Eng, M.J.
