Activity 3: Learning Unit 1‐3: ADDRESSING Q.3.1 Explain why devices on a network need addresses. (5) Q.3.2 Explain the difference between a MAC address and an IP address. You should relate your answer to the OSI model. (6) Q.3.3 Explain how devices get their MAC or IP address. (4) Q.3.4 Explain how a packet gets from one network to another. Your explanation should relate this movement to the IP address format. (5) Q.3.5 As the Internet has expanded, we have run out of IP addresses. Outline TWO ways how this problem has been overcome.
Consider the following equations. 𝐴 = 2𝑥 𝐵 = 2 cos 𝑥 , 𝑤ℎ𝑒𝑟𝑒 𝑥 𝑖𝑠 10° , 20° , 30° … 180° 𝐶 = ∑ 𝑛 + 5 5 100 𝑛=0 Construct a C++ program to calculate and print out the value of A, B and C by considering the following conditions; 1- User must keyed-in “start” and “stop” to control the program. 2- Use function to display all the above equations. 3- If user keyed-in “function1”, calculate the value of A divided by C for the value of x from 1 to 100. 4- If user keyed-in “function1”, calculate the value of B divided by A for the value of x from 2 to 200.
