| 85 | 01010101 in decimal |
| Mantissa | This part represents the actual number (in Floating Point Representation) |
| Exponent | This part represents the number of places to float/move the decimal place |
| increase the accuracy | Increasing the number of bits for the mantissa has what effect on the number |
| decrease the range | Decreasing the number of bits for the exponent will have what effect on the number |
| 1111 1111 | 255 in binary |
| 256 | How many different numbers we can represent with 8 bits |
| 11011101 | -35 in binary using Two's Compliment Notation (in 8 bits) |
| American Standard Code for Information Interchange | ASCII? |
| 7 | How many bits is ASCII? |
| Control Characters | These are the characters which are non-printable, they control the format of the text |
| Character Set | These are all the characters which can be represented |
| 16 | How many bits is UNICODE? |

| 1 Gigabyte | 1024 Megabytes is better known as |
| bitmap | type of graphics file in which it saves the colour of every individual pixel |
| vector | type of graphics file which saves the attributes of objects in the image i.e. size, colour, x and y co'ods is attributed to what graphics package? |
| bitmap | fixed resolution printing is attributed to what graphics package? |
| bitmap | saves the full screen - even if its blank is attributed to what graphics package? |
| bitmap | memory requirements remain the same if the complexity of the image is increased is attributed to what graphics package? |
| vector | resolution independance - prints at the highest resolution available on the printer is what graphics package? |
| compression | this reduces the file size of an image meaning we save on memory space |
| lossy | type of compression that loses some of the image quality on compression |
| lossless | type of compression which has no affect on image quality on compression |
