Question

what is the role mechanical concept in atm machine?

Answer 1

An ATM is simply a data terminal
with two input and four output
devices. Like any other data
terminal, the ATM has to connect to,
and communicate through, a host
processor. The host processor is
analogous to an Internet service
provider (ISP) in that it is the
gateway through which all the
various ATM networks become
available to the cardholder (the
person wanting the cash).
Most host processors can support
either leased-line or dial-up machines.
Leased-line machines connect
directly to the host processor through
a four-wire, point-to-point,
dedicated telephone line. Dial-up
ATMs connect to the host processor
through a normal phone line using a
modem and a toll-free number, or
through an Internet service provider
using a local access number dialed by
modem.
Leased-line ATMs are preferred for
very high-volume locations because
of their thru-put capability, and dial-
up ATMs are preferred for retail
merchant locations where cost is a
greater factor than thru-put. The
initial cost for a dial-up machine is
less than half that for a leased-line
machine. The monthly operating
costs for dial-up are only a fraction
of the costs for leased-line.
The host processor may be owned by
a bank or financial institution, or it
may be owned by an independent
service provider. Bank-owned
processors normally support only
bank-owned machines, whereas the
independent processors support
merchant-owned machines.
