How do ATMS work?

When a cardholder wants to do an ATM transaction, the user provides necessary information through a card reader and keypad. Once the funds are transferred from the customer account to the host processor bank account, the processor sends the approval code to the ATM and the authorized machine to dispense the cash.

Where is ATM network used?

Asynchronous Transfer Mode (ATM) can be used as the underlying technology for Fiber Distributed Data Interface (FDDI), Synchronous Optical Network (SONET), and other high-speed networks. Plus, ATM can run on any media including coax, twisted-pair, or fiber-optic.

What design principles is the command pattern using?

In object-oriented programming, the command pattern is a behavioral design pattern in which an object is used to encapsulate all information needed to perform an action or trigger an event at a later time. This information includes the method name, the object that owns the method and values for the method parameters.

What are the design principles of OOP?

Object-Oriented Design Principles are the core of OOP programming. They include Abstraction, Encapsulation, Polymorphism, and Inheritance. They will help you create a clean and modular design, which would be easy to test, debug, and maintain in the future.

How does an ATM work in a network?

ATM technology is designed for improvement the quality of service and utilization on the high-traffic networks. ATM works on the data link layer over twisted-pair cable or fiber. ATMs use the asynchronous time-division multiplexing and encode the data into the cells (the small fixed-sized packets).

What to consider when designing a distribution network?

Many small sized businesses grow until they reach a point where they need to seriously consider how their distribution network can be better optimized to keep their customers satisfied without going to any unnecessary expense.
