Across
- 4. a finite set of instructions that accomplish a task.
- 5. a type of problem for which no algorithm can be constructed that is always capable of providing a correct yes-or-no answer
- 7. involves one key for both encryption and decryption.
- 9. a computing model in which programs run in order one command at a time.
- 11. a computing model in which programs are broken into small pieces some of which are run simultaneously
- 14. software intended to damage a computing system or to take partial control over its operation
- 15. a system that requires at least two steps to unlock protected information
- 16. a process of encoding messages to keep them secret so only "authorized" parties can read it.
- 17. a type of problem with a yes/no answer
- 20. the time used to complete a task sequentially divided by the time to complete a task in parallel
- 22. a search algorithm which checks each element of a list in order until the desired value is found
- 23. a measure of how many steps are needed to complete an algorithm
- 24. infects and spreads across computing devices
- 25. a technique that attempts to trick a user into providing personal information. That personal information can then be used to access sensitive online resources such as bank accounts and emails
- 27. provides a "good enough" solution to a problem when an actual solution is impractical or impossible
- 28. the use of a program to record every keystroke made by a computer user in order to gain fraudulent access to passwords and other confidential information
Down
- 1. putting steps in an order.
- 2. pairs a public key for encryption and a private key for decryption. The receiver’s private key is required to decrypt the message
- 3. a wireless access point that gives unauthorized access to secure networks.
- 6. algorithms with a polynomial efficiency or lower (constant linear square cube etc.) are said to run in a reasonable amount of time.
- 8. a search algorithm that starts at the middle of a sorted set of numbers and removes half of the data; this process repeats until the desired value is found
- 9. deciding which steps to do next.
- 10. includes a program as an integral part of its function. Can be physical or non-physical computing software or non-physical computing concepts
- 12. doing some steps over and over
- 13. a computing model in which programs are run by multiple devices
- 18. algorithms with exponential or factorial efficiencies are examples of algorithms that run in an unreasonable amount of time.
- 19. a type of problem with the goal of finding the "best" solution among many
- 21. a process that reverses encryption taking a secret message and reproducing the original plain text.
- 26. information about an individual that identifies links relates or describes them.
