How the components of technology systems work together

Computer hardware devices

● devices (PC, server, laptop, tablet, games console and other programmable digital devices)
● input – keyboard, mouse, sensors, touch screen, microphone, scanner, digital camera
● output – printers (inkjet, laser, impact), speakers, force feedback devices, actuators, screens, projectors, robot arms, other control devices
● storage devices – solid state, optical media, magnetic media
● that modern technology devices are often multifunctional (have both input and output functionality)
● how hardware components and software can be combined to form an automated technology system (self-service checkout, production line)
● the uses of devices that capture data for automated systems (barcode readers, magnetic strip readers, optical character readers (OCR), optical mark readers (OMR) and radio frequency identification systems (RFID))
● suitable devices to suit the requirements for a specific user and purpose, and justify their use.

Computer networking

● the purpose of different types of network (local area network (LAN), wide area network (WAN), personal area network (PAN), mobile broadband)
● the common uses of network systems (resource sharing, data sharing, entertainment, communication)
● the benefits of computer networking
● the need to synchronise data held on devices forming a PAN.

Data transfer

● physical methods of transferring data between devices using wireless or cabled topology to meet the requirements for a specific user and purpose
● wireless methods of transfer including the use of Wi-Fi and Bluetooth technologies
● cabled methods for transfer of data between devices, including the use of optical fibre, unshielded twisted pair (UTP) and coaxial cables
● the benefits and drawbacks of these physical methods.
