what is big-endian and signed integer representarion

 

• least significant byte in lowest address is called little-endian.

so big-endian means the most significant bytes will in the lowest address.

and usually,the byte in lower address will display first.

for example,0x0500000000(memory 05 is lowest),if in little-endian,as intel architecture,it means

00000005.

• negative or signed integer will most commonly present in a notaion known as "two-complication"

the formula is illutrated as B2T=-X_w-12^w-1+sigma(i=0 to w-2)X_i2ⁱ,

so if we want to say -16,it will be in hex 0xfffffff0.
