Hi there,
Segments in 8086 are separated by 16 bytes which is called paragraph. What is the need of paragraph and why should it be divisible by 16
 
Never heard of a paragraph before....... segments in real mode are 64k because of the 16 bit pointer... I program mainly in C, so I never went into that much detail...

16bit pointer and 16bit offset register gave up to 4meg address space ( the first four LSB's aren't used in memory addressing.... maybe that's what you mean '16 bytes')

There are 20 address pins but the first 4 are used for peripheral id's and such.. so I suppose the segments are 16 bytes apart...
