Today's Topics
- The significance of the bit and powers of 2
- Data quantities (B, kB, MB, GB, etc)
- Number systems (decimal, binary)
And Firstly
What Do you think About the (bit) ??
Bit is the binary diget (1 OR 0) , (True OR False)
bit is unit of information
The Significance of the Bit
- A bit (Binary digIT) is merely 0 or 1
- It is a unit of information since you cannot communicate with anything less than two states
Decimal Number System
- This system of number is commonly used in accountting and other fields
- it's used (0123456789) shapes of ten numbers to create a new value
And as the image show the possition of number chang it's value but the base is 10
because the system is decimal
Binary
Binary is exactly the same, only instead of ten digits/states (0 to 9) we have just two (0 OR 1), so the base becomes 2:
so that number Equal
16+0+4+2+0 = 22 in decimal
22 = 10110 in binary
Larger Units of BIT
- Byte 8 BIT
- Strictly the SI units since 1998 are:
- Kibibyte (KiB)
- 1024 bytes (closest power of 2 to 1000)
- Mebibyte (MiB)
- 1,048,576 bytes
- Gibibyte (GiB) 1,073,741,824 bytes
