Expert Solution
Step 1
Integer variables, for example, can be represented in one of two ways: signed or unsigned.
Signed numbers can distinguish between negative and positive values using a sign flag.
Unsigned numbers, however, only store positive numbers and ignore negative numbers.
Lets Add the unsigned integer number pairs provided below to do the addition in binary, the word size is 8 bits.
5+6=?
These two numbers will be converted to binary values and then simply can be added . As we know, 0+1=1 and 1+1=10
Word size =8 bits , So, 8 bits are taken
| 27 =128 | 26 =64 | 25 =32 | 24 =16 | 23 =8 | 22 =4 | 21 =2 | 20 =1 | |
| 5 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 1 |

(00001011)2= (11)10
8-bits binary number of (5+6) is (00001011)2
