1.1 Computer hardware, i.e.: • input devices • output devices • communications devices • benefits (e.g. integrated devices make portable devices simpler to use) • limitations (e.g. voice recognition performs poorly in noisy environments) • uses (e.g. membrane keyboard could be used in harsh physical environments)

1.2 Computer components, i.e.: • processors • motherboards • storage (i.e. hard drive, solid state, flash, internal, removable, SAS, SCSI, portable, Cloud) • ports (i.e. USB, Firewire, SATA, Network, Fibre Channel) • memory (i.e. RAM, ROM, cache) expansion cards (i.e. sound, network, graphics, storage controller, fibre channel) • power supplies • characteristics • purpose

1.3 Types of computer system, i.e.: • desktop/server • tablet/hybrid • smartphone • embedded system/Internet of Things (e.g. cars, home appliances, etc.) • mainframe • quantum • uses (e.g. tablet device can be used when travelling due to physical properties) • benefits (e.g. desktop computer can have a large screen which can improve productivity) • limitations (e.g. mainframe
