3QUESTION. 1A).If a tiny computer that has a word size of 8 bits is given, then the largest positive numberwill be (01111111) i.e. +127 and the smallest negative number will be (10000000) i.e. -127.1.One’s complementLargest positive number- (01111111) i.e. +127Smallest negative number- (10000000) i.e. -1282.Two’s complementLargest positive number-(01111111) i.e. +127Smallest negative number-(10000000) i.e. -1283.Signed magnitudeLargest positive number-(01111111) i.e. +127Smallest negative number-(10000000) i.e. -1284.Unsigned magnitudeLargest positive number-(01111111) i.e. +127Smallest negative number-(00000000) i.e. 0B.)i). 0X5AB into octal(0)16= (0000)2(5)16= (0101)2(A)16= (1010)2(B)16= (1011)2Hence, (05AB)16= (010110101011)2In octal,010=2, 110=6, 101=5, 011=3Hence, octal equivalent of 05AB is 2653.
