How many bytes are there in 1 KB (MB,GB,TB,PB,EB,ZB,YB) and What is KiB, MiB, GiB etc in representing memory?

Bit is a unit of information expressed as either 0 or 1 in binary notation, and it is the smallest unit of data in the computer. Byte is unit of data that is 8 binary digits (bits) long. 

Most of the people know the terms up to GB(GigaByte),TB(TeraByte). What is the next symbol after TB? The symbols for representing memory(in binary notation) after TB are PB(PetaByte), EB(ExaByte), ZB(ZettaByte), YB(YottaByte).
And many people want to know how many bytes are there in 1 MB or GB or TB etc and how many zeros are there in these representations(MB,GB,TB,PB). 
Sometimes we see the symbols KiB,MiB,GiB etc while downloading or installing the softwares, All these details are given below ...Check it

• 1 KB = 1000 Bytes = 10³ Bytes = 1024 Bytes (In binary interpretation) = 2¹⁰ Bytes
  
• 1 MB = 1000 000 Bytes = 10⁶ Bytes = 1024 KiloBytes = 2²⁰ Bytes
  
• 1 GB = 1000 000 000 Bytes = 10⁹ Bytes = 1024 Mega Bytes = 2³⁰ Bytes
  
• 1 TB = 1000 000 000 000 Bytes = 10¹² Bytes = 1024 Giga Bytes = 2⁴⁰ Bytes
  
• 1 PB = 1000 000 000 000 000 Bytes = 1000⁵ Bytes = 10¹⁵ Bytes = 1 million gigabytes = 1024 Tera Bytes = 2⁵⁰ Bytes
  The prefix peta indicates the fifth power to 1000
  
• 1 EB = 1000 000 000 000 000 000 Bytes = 1000⁶ Bytes = 10¹⁸ Bytes = = 2⁶⁰ Bytes
  
• 1 ZB = 1000 000 000 000 000 000 000 Bytes = 1000⁷ Bytes = 10²¹ Bytes = = 2⁷⁰ Bytes
  
• 1 YB = 1000 000 000 000 000 000 000 000 Bytes = 1000⁸ Bytes = 10²⁴ Bytes = = 2⁸⁰ Bytes
  
  

The terms kibibyte(KiB), mebibyte(MiB), gibibyte(GiB), tebibyte(TiB), pebibyte(PiB), exbibyte(EiB), zebibyte(ZiB),yobibyte(YiB) which is used as multiples of 1024 (binary prefix notation) according to International Electrotechnical Commission(IEC) Standard. 

Ex: 1 gigabyte = 10⁹ bytes which is equal to 1000000000 bytes
     1 gibibyte =  2³⁰ Bytes which is equal to 1073741824 bytes
