| 2 major things that affect the speed of a computer |
|
Definition
| The computer’s processing speed, that is how fast it “thinks”, is controlled by the size of the bit unit the silicon chip can handle, the speed of the clock on the motherboard, and the presence and type of any coprocessor chips. The memory the computer uses for processing is the random access memory (RAM). |

|
Definition
-size of processing unit (chip)
-speed of clock
-presence of coprocessors. |
