What is a data communication system in the context of banking?
A data communication system is a set of hardware, software, and transmission media that enables electronic transfer of data between computers and devices across locations, forming the backbone of modern banking operations.
What is the role of a repeater in extending a banking network?
Repeater amplifies and regenerates weak signals over long distances.
What does the term 'bandwidth' refer to in data communication?
Bandwidth refers to the maximum rate of data transfer across a communication channel, typically measured in bits per second (bps), and determines how much data can be transmitted in a given time period.
What is half-duplex communication in a banking data network?
Data flows in only one direction at a time between two points.
What is the difference between analog and digital signals in data communication?
Analog signals are continuous waveforms that vary in amplitude and frequency, while digital signals represent data as discrete binary values (0s and 1s); most modern banking networks use digital transmission for accuracy and speed.
What is the function of a gateway in a bank's network?
Gateway connects networks using different protocols or architectures.
What is a modem and what role does it play in banking communication?
A modem (modulator-demodulator) converts digital signals from computers into analog signals for transmission over telephone lines and vice versa, enabling banks to connect legacy systems over PSTN networks.
What is a bridge and how does it differ from a router in banking networks?
Bridge connects two LAN segments; router connects different networks.
