Bits And Bytes

What is a digit?
A digit is a single place that can hold numerical values between 0 and 9. Digits are normally combined together in groups to create larger numbers
“normal” counting numbers used in everyday life a based on what sequence of numbers?
Digits are normally combined together in groups to create larger numbers. For example, 6,357 has four digits. It is understood that in the number 6,357, the 7 is filling the "1s place," while the 5 is filling the 10s place, the 3 is filling the 100s place and the 6 is filling the 1,000s place. So you could express things this way if you wanted to be explicit:



(6 * 1000) + (3 * 100) + (5 * 10) + (7 * 1) = 6000 + 300 + 50 + 7 = 6357

Where does the word bit originate from?

 The word BIT was first used in a 1948 Paper. Theword bit is a portmanteau word for binary digit or a possibly binary digit.

Binary numbers don’t use base 10. What base do they use? What digits are available in base 2?

It operates in BASE 2, the numbers that make up the base 2 system are 0 and 1.

 

 

( 4 * 1000) + ( 3* 100) + ( 2*10 ) = ( 1 *1) = 4000 + 300 + 20 + 1

A group of binary digits or bits (usually eight) operated on as a unit.

How many bytes in a kilo, mega,giga and tera  byte?

HOW MUCH IS:

1000MB = 1 GB
500 GB = approximately 500 000 megabytes
500 KB = approximately 0.5 megabytes
