HARDWARE DEVICES
Module 1.2
, COMBINING INPUT SOURCES AND OUTPUT DESTINATIONS
Most ICT systems use multiple input sources and output destinations to enhance productivity
Smartphone or tablet may have
Sensors to detect movement Onscreen controls
POS (Point Of Sale) system might use
Specialised till keyboard + barcode scanner + card reader + fingerprint scanner
Musicians might connect
MIDI piano keyboard + computer using USB + keyboard and mouse
PROCESSING
Relies on software
Only takes place if software and data are loaded into RAM
Uses a step-by-step solution (algorithm) to solve problems
Uses data that has been input, creates information that can be output
STORAGE
Choose correct storage media
Security ( Encryption and physical safe keeping )
Good backup policies
INPUT DEVICES
Allows the ICT device to receive data and instructions
First step in any information processing system
Usefulness of efficiency depends on skill of user
