| Question | Answer |
| Computer Science Stuff | I'm not sure what to put on here |
| What is binary | Binary is a counting system for computers. Why do computers use Binary? So they can store data with 0 - 1 |
| What are transistors? | A semiconductor device with three connections, capable of amplification in addition to rectification |
| what is binary made up of | Binary is made up of 8 bits: 128, 64, 32, 16, 8, 4, 2, 1 |
| How do you add and subtract in binary | 1111+0111 = 10110 Denary: 15+7= 22 |
| Hex | Hex is also another way people convert denary numbers since it is faster. |
| fun | To work these out you either work out the binary and convert it. But I think you can work out denary to hex straight away. Using the so good booklet we have to use to revise things with much information. |
