| define hardware | parts of a computer that can be touched or felt |
| define software | programs and data that make the computer hardware function |
| define microprocessor | computer's main processing unit; "brain" and carries out actions |
| define information processing | capturing, storing, and updating data and information |
| define random access memory (ram) | memory available on the computer for storing data and programs that are being processed |

| define hard drive | main device used to store information on a computer |
| define optical disks | used to store computer or media data |
| define removable media | portable device that stores computer data |
| define integrated circuit | a complete circuit on a chip, built by the computer's process |
| define embedded processors | a chip designed with a specific set of usable instructions |
| define download | to transfer files or data from one computer to another |
| define artificial intelligence | a part of computer science that tries to be like human intelligence |
| what kind of a processor does a coffee maker have? | embedded |
| how many bites are in a kilobyte? | 1000 |
| what are small dots on a computer screen called? | pixels |
| How many bits are in a byte? | 8 |
| What is the flow of electrons called? | current |
| what is it called when a microprocessor gets instructions from memory? | fetch |
| What is manipulation of data by a microprocessor called? | processing |
| name two materials that microprocessors are composed of. | quartz, metals, chemicals, and water |
| Name two conductors of electricity. | Anything metal |
| When a microprocessor determines what the instructions mean | decodes |
| Name the four main components of a computer | input, storage, processing, and output |
| What is the translation of this bianary code: 00000010 | 2 |
| Branch of computer science that simulates human intelligence | artificial intelligence |
| programs that make computer hardware function | software |
| What happens when you increase resistance? | The electrons move slower |
| What happens when you decrease resistance? | The electrons move faster |
| define power switch | supply of moving elecrons |
| define switch | device that enables you to turn the current on and off |
| define load | a part that consumes power supplied by the power source |
