Byte System
Byte System¶
A computer processor is made up of multiple decisive circuits, each one of which may be either OFF or ON. These two states in terms of memory are represented by a 0 or 1. In order to count higher than 1, such bits (BInary digiTS) are suspended together. A group of eight bits is known as a byte. 1 byte can represent numbers between zero (00000000) and 255 ( 11111111), or 28 = 256 distinct positions.
These bytes may also be combined to represent larger numbers. The computer represents all characters and numbers internally in the same fashion.
Tabular Representation of various Memory Sizes¶
| Name | Equal To | Size(In Bytes) | Approximation in Power |
|---|---|---|---|
| Bit | 1 Bit | 1/8 | - |
| Nibble | 4 Bits | 1/2 (rare) | - |
| Byte | 8 Bits | 1 | 10^0 |
| Kilobyte | 1024 Bytes | 1024 / (2^10) | 10^3 |
| Megabyte | 1, 024 Kilobytes | 1, 048, 576 | 10^6 |
| Gigabyte | 1, 024 Megabytes | 1, 073, 741, 824 | 10^9 |
| Terrabyte | 1, 024 Gigabytes | 1, 099, 511, 627, 776 | 10^12 |
| Petabyte | 1, 024 Terabytes | 1, 125, 899, 906, 842, 624 | 10^15 |
| Exabyte | 1, 024 Petabytes | 1, 152, 921, 504, 606, 846, 976 | 10^18 |
| Zettabyte | 1, 024 Exabytes | 1, 180, 591, 620, 717, 411, 303, 424 | 10^21 |
| Yottabyte | 1, 024 Zettabytes | 1, 208, 925, 819, 614, 629, 174, 706, 176 | 10^24 |
Currency System¶
- 1 Thousand = 10^3
- 1 Million = 10^6
- 1 Billion = 10^9
- 1 Arab = 10^10
- 1 Kharab = 10^11
- 1 Trillion = 10 ^12
