1. The amount of random access memory (RAM) that is installed in a computer.






2. A small circuit board that holds a series of random access memory (RAM) chips.






3. A port that can connect a wide variety of peripherial devices to the computer - including keyboards - printers - mice - smartphones - PDAs - flash drives - and digital cameras.






4. A device such as a monitor - printer - or keyboard that connects to the system unit through ports.

14. Comprises computing devices - softeare - or peripherals that use techniques - parts - and methods from an earlier time that are no longer popular.






15. A computer-controlled mannequin that simulates human body functions and reactions.Patient simulators are used in training doctors - nurses - and emergency services personnel by simulating dangerous situations that would put live patients at risk.






16. 'The computer's temporary storage space or short-term memory. It is located in a set of chips on the system unit's motherboard - and its capacity is measured in megabytes or gigabytes.'






17. 'A drive that uses the same kind of memory that flash drives use - but can reach data in only a tenth of the time a flash drive requires.'






18. 'A type of network design in which users are not responsible for creating their own data backups or providing security for their computers; instead - those tasks are handled by a centralized server - software - and a system administrator.'






19. Any part of the computer you can physically touch.






20. About a billion bytes






21. Programs for creating or editing two-dimensional line-based drawings.






22. Twisted pair cable that contains a layer of foil shielding to reduce interference.
