1)ATM cash dispenser The ATM is the Machine abbreviation of the Automatic Teller, the meaning is an automatic cabinet member machine, because of greatly part of used for withdraw money, and then call a cash dispenser.It is the machine electricity integral whole disguise of a kind of height nicety to place, make use of the self-help service that card or intelligence card of the magnetism code carry out financial bargain and replace the bank cabinet noodles personnel's work.Can withdraw cash, search savings surplus amount, carry on an of account a funds to transfer funds, surplus amount search etc. work;Can also carry on cash deposit(solid hour enter in ledger), check savings(domestic have no), deposit book to repair to ascend, in the center business etc. work.The card holder can use credit card or save card and carry out an au to withdraw money, search surplus amount, transfer according to the password, cash deposit, the deposit book repairs to ascend, purchase a fund and change a password etc. business.
Invent ATM
In 1939, the Luther George Simjian invented a cash dispenser.But, the cash dispenser of modern meaning, its concept puts forward in 1968 and the prototype machine appears in 1969.The first set the cash dispenser be installed in the chemistry bank of New York.Now, ATM machine the speed of the development is very quick and come to a with the comparison of bank organization 4:1.The American navy even packed the ATM machine to warship up.
Main produce the manufacturer as NCR
(2)The ATM is that the Asynchronous Transfer Mode(ATM) different step delivers mode
The ATM is a data to deliver a technique.It is applicable to the bureau area net and wide area network , it has a high-speed data to deliver a rate and supports many category type like voice, data, fax, solid hour the correspondence of the video frequency, the CD quality audio frequency and picture.
The ATM is the breadth of transmission voice, video frequency picture and data to take a technique on the LAN or the WAN.It is in a letter dollar after the technique and the data cent set size fix.You can imagine a letter dollar a kind of conveyance equipments, can through data piece the ATM exchanges an equipments to deliver to another equipments from an equipments.All letter dollar has same size and be unlike frame relay and all of the not certain of the data cent set of the bureau area net systems.The letter dollar which uses same size can provide a kind of method and anticipate and promise an application the bandwidth need.Like car's crossing a street corner in the busyness have to wait for a long truck a turn and the data cent set of variable length is easily exchange an equipments to cause correspondence to delay.
The ATM is real to have the dual of electric circuit commutation and cent set commutation:
The ATM faces to a conjunction, it needs to be correspond by letter both parties to link toward the establishment, the correspondence end after again is make by the letter to tore down a conjunction.But it discarded electric circuit commutation in adoption of synchronous hour separately reply to use, change to use difference step hour separately reply to use, the clock which receives and dispatch both parties can be different, can more availably make use of a bandwidth.
The ATM transmission unit is the CELL(letter dollar) of the fixed-length 53 bytes, letter head cent included choice road from use of VPI/VCI information, as a result it has a switching characteristics.It is that a kind of high-speed cent set exchange, it correct on the agreement OSI the thirdly wrong, flow to control function to transfer smart terminal on the completion, postpone while lowering a network, raised to exchange speed.
Exchange an equipments is an ATM of the importance constitute part, it can used to organization inside of Hub, quickly deliver to the data cent set is from a node another node;Perhaps used to a wide rea correspondence an equipments, fast deliver an ATM letter dollar between the long range LAN.The ether net, fiber-optic distribute type data connects and lie quality the card wreath's net's etc.'s traditional LAN adoption share and any time only a node can carry on transmission, but the ATM provide arbitrarily the conjunction of node and the node can carry on transmission in the meantime.The information from different node is replied to use to become a letter dollar to flow by many roads.In that system, the ATM exchanger can be owned to perhaps organize an internal net by the promoter of public service of a part.
The ATM useds to a company main stem net, can simplify the management of network, remove many because of different plait address project and road from choice mechanism of the complicated problem that network cause when with each other connect.The ATM gathers a line machine and can provide to gather a line machine to take a post idea both ends the conjunction of, but has nothing to do with the equipments type link.The addresses of these equipmentses are all prepared transformation, for example very easy send out 1 to report a text from a node to another node, but need not consider the network type that the node connect.The ATM management software usage door and their physical work stations move a place very convenient.
The technique of pass the ATM can complete the bureau area of business enterprise headquarters and each office and the company cent department a net with each other allied, carry out a company an internal data transmission thus, business enterprise mail service, the words sound service etc., and pass to carry out electronic commerce up the allied INTERNET etc. application.In the meantime because of ATM adoption the covariance reply to use a technique, and connect into a bandwidth the breakthrough originally possessed of 2 Ms, attain a 2 Ms Ms-155ses, so in keeping with high bandwidth, low postpone hour or high data abrupt etc. application.
In the diagram:The UNI connects for the customer - networkThe NNI connects for the network - nodeThe GFC is a general discharge control areaThe VPI is falsely a path marking signThe VCI is falsely a passage marking signThe PT is a clean lotus type, namely behind 48 information types of the word stanza information areasThe RES is a reservation, can used to will expand definition in the future, now appointed its Heng is 0The CLP throws priority away for the letter dollar, while letter dollar happenning conflict, the CLP uses to explain whether that can throw away or notThe HEC checks code for the letter head school, examine polynomial and this word reduces expenses to exactitude of promise the whole letter head to deliver.
