| Bit | A bit is a single unit of storage which acts as an electrical switch which detects electrical impulses. If there is one present then the switch is 'on', otherwise it is 'off'. A bit can hold either a 1 or a 0. |
| Nibble | 4 Bits |
| Byte | 8 Bits |
| Kilobyte | 8,000 Bits 1,000 Bytes |
| Megabyte | 8,000,000 Bits 1,000,000 Bytes 1,000 Kilobytes |
| Gigabyte | 8,000,000,000 Bits 1,000,000,000 Bytes 1,000,000 Kilobytes 1,000 Megabytes |
| Terabyte | 8,000,000,000,000 Bits 1,000,000,000,000 Bytes 1,000,000,000 Kilobytes 1,000,000 Megabytes 1,000 Gigabytes |
| Petabyte | 8,000,000,000,000,000 Bits 1,000,000,000,000,000 Bytes 1,000,000,000,000 Kilobytes 1,000,000,000 Megabytes 1,000,000 Gigabytes 1,000 Terabytes |
| Why does data need to be converted into binary to be processed by computers? | -Computers function by receiving electrical impulses. These impulses are stored in singular units called bits. A bit can store one of two values: 1s or 0s. -It can be thought of as a switch, it can either be on if an impulse is present or off if it is not. If this electrical switch is on then the bit holds the value of 1 and if it is off then a 0 (usually). -Computers specifically use binary as it only has two bases (1s and 0s). This is needed as the 'switch' can only exist in two states: on or off. -To conclude, binary is a way of representing text, numbers, images etc. and it is needed because computers can only understand binary. |
