Any other formats like scan images, PDF, zip, rar, ppt and bmp etc will not be accepted.
Objective of this assignment is to increase the learning capabilities of the students about
• To understand the conversion of numbers in to binary by using arithmetic operations.
• To understand the basic concept of logical operations and how to use it to solve a problem.
No assignment will be accepted after the due date via email in any case (whether it is the case of load shedding or internet malfunctioning etc.). Hence refrain from uploading assignment in the last hour of deadline. It is recommended to upload solution file at least two days before its closing date.

Question # 01 10 marks
In CPU all the arithmetic operations are performed in binary numbers (0 and 1). Suppose you have a small CPU which is designed to perform all arithmetic operations using addition only. You will explain how the following operations will be solved out by the CPU.
i) Multiplication of 6 and 2
ii) Addition of 7 and 3
iii) Subtraction of 5 and 4
Question # 02 10 marks
You have an image that can be represented in 8 bits. The image is given below:
You are required to send this image to someone but not in original form. So, nobody can extract the features from the image.
So, we will perform following two operations on the image.
You will apply an 8-bit (10101011)2 mask using AND logic operation.
You will invert the masked image using XOR logic operation.
