Base 16 or Hexadecimal is a sequence of 16 sequential caricatures starting from Zero ( 0 ) to ( 16 ). The numbering system starts from 0-9 then A-F up to 16. (See Below for an example). The prefix (0x ) expresses that the value is a HEX value. A decimal value of 8 will be expressed in HEX as a 0x8 another example would be a decimal value of 10 will be expressed as 0xA. If you’ve been around computers long enough you probably overheard people talk about how much ram or memory their computer or cell phone has. it is always measured in a sequence of eight then doubled. 8, 16, 32, 64 and so on, most of the time the hardware will be grouped. In most computers there are two slots for RAM, if you wanted to add more RAM and it currently has 16 gigs of RAM you would have two chips of 8 gigs if it has two lots, an upgrade choice would be 32, 64, 128, 256. A choice of 32 would be two chips of 16 gigs each. The hardware would represent the number of bytes the chip can process or hold. One Byte is equal to 8 bits. So what’s a Mega Byte? A Mega Byte is 1 million bytes of data. 1 HEX value is 4 Bits or a half a Byte.
