Question

I am stuck on HEX(intel hex) format which I see in Hex Editor (Hex Editor Neo). Ok,I know hex,decimal,binary,their addition,multiplication,their conversion.

Ex. sample.jpg (this is a jpg file I open with Hex Editor Neo in hex format with 4 columns)


ff d8 ff e0
00 10 4a 46
49 46 00 01
01 01 00 48
00 48 00 00
ff db 00 43
00 05 03 04
04 04 03 05
04 04 04 05
05 05 06 07
0c 08 07 07
07 07 0f 0b 
0b 09 0c 11

I see this(these are just some of the rows from the whole file) type of hex code. I am interested in what they mean? I know ff d8 ff e0 tells you jpg. I know jpg ends with ff d9. I want to know about other codes..I mean why they are their?.They must be having some meaning or how the conversion takes place from picture to hex.

What do you mean by "4a 46 49 46 00" and many others present there?
