bits and bytes ;)
1. what is a digit ? a digit is a single place that can hold a numerical value between 0 and 9. Digits are normally combinded together in groups to create larger numbers.
2. you may be asking what is the base 1o system ? The base-10 number system is known as the decimal number system. but be warned, they are extremely expensive.
3.where does the word bit originate from? it's like a failed attempt at an acronym 'binary digit'
4.how would you write 4,321? well i'd write it as 4,321..but you could also write it as; (4 * 1000) + (3 * 100) + (2 * 10) + (1 * 1) = 4000 + 300 + 520 + 1
5.write the following numbers in binary (base 2)
21 = 10101 (base 2) = (1 x 16) + (1 x 4) + (1 x 1)= 21 (base 10)
24 = 11000 (base 2) = (1 x 16) + (1 x 8) = 24 (base 10)
30 = 11110 (base 2) = (1 x 16) + (1 x 8) + (1 x 4) + (1 x 2) = 30 (base 10)
6. what is a byte? a byte is a sequence of 8 bits processed as a single unit of information
7. How many bytes in a kilo, mega, giga and tera bytes.
1 kilo: 1024 bytes
1 mega: 1048576 bytes
1 giga: 1073741824 bytes
1 tera byte: 1099511627776 bytes
and there are some extra questions, which i attempted, but the numbers were too large and freaked me out, so i didn't do them :/
