Across
- 2. the data collected by an device used by the IoT device in order to make a decision
- 3. an input device that collects data on how warm or cold an area is
- 6. (IoT) a device of this type is a device that connects to the internet so that it can 'talk' to other devices; often referred to as 'smart' devices
- 7. that use computer hardware to run
- 8. provides the power to all the components in a computer that need it
- 14. an input device that collects data on how much illumination there is in an area
- 17. an input device that collects data on movements in an area
- 18. the output if the condition is met
- 19. a type of storage that uses a laser to write data to and read data from a disc; examples include CD drives/CDs, DVD drives/DVDS and Blu-ray Disc drives/Blu-ray Discs
- 21. the thing that stores the data for a device that cannot store it itself for example, CDs and DVDs, the plural is storage media
- 23. a device that allows information to be entered into or retrieved from a computer; these are normally divided into input devices, output devices and external storage devices
- 25. a device that allows the user to display the results after a computer has processed data, for example, monitor and speakers
- 27. an input device that collects data on the force being applied to a device
- 29. not accessed constantly by the computer; there are three types: optical, magnetic and Solid State
- 30. an additional component of a computer that plugs directly into the motherboard; used to output and display content on a screen
- 33. the permanent storage in a computer; there are two main types, magnetic and solid—state
- 34. unit of speed
- 35. how many fetch—decode—execute cycles a CPU can process per second; often referred to as just 'speed'
- 36. an input device that collects data on the location of a device
Down
- 1. a type of storage that uses motion of electric charge and a write/read head to write to and read from the disc; examples include hard drives and data tapes
- 4. each 1 and O in a binary number
- 5. is storage connected directly to the motherboard of a computer, data stored here can be accessed more quickly than data stored on the hard drive
- 9. hardware or computer peripheral that stores data or saves data, for example, magnetic hard drives and CD drives
- 10. a type of storage that uses miniature electronic switches to store data, has no moving parts and provides very fast access to data; examples include memory sticks, memory cards and SSDs
- 11. an input device that collects data when speech or other sounds are detected
- 12. use a laser to read from or write to optical discs
- 13. saves data, for example, a memory stick
- 15. the main circuit board found in a computer which connects all the components together so they can communicate
- 16. what the data has to be for an action to be performed; the condition in an if statement must be a question that can be answered with true or false
- 20. accessed directly by the CPU and normally the fastest memory in a computer; RAM is an example
- 22. the Central Processing Unit carries out all the processing in a computer by completing the fetch—decode-execute cycle
- 24. an input device that collects data when text or numbers are typed in
- 26. a device that allow the user to enter data into a computer, for example, keyboard and mouse
- 28. unit of storage
- 31. data is stored online and software is used via an internet browser, rather than being stored locally on a computer's hard drive (e.g. Google Drive, OneDrive)
- 32. the physical parts of a computer that you can touch
