Design the network for an organization granted the network ID 166.44.0.0/18 by determining: the subnet mask in binary and in decimal, number of subnets, number of hosts per subnet. Also, design all subnets of the network by determining for all subnets: subnet ID, the IP address of the first host, the IP address of the last host, and the broadcast address. Question 2 (30 marks) Differentiate between the following: 2.1. Logical Link Control (LLC) and Media Access Control (MAC) sublayers 2.2. Carrier sense multiple access with collision detection (CSMA/CD) and Carrier sense multiple access with collision avoidance (CSMA/CA) Question 3 (30 Marks): 3.1. Find the cyclic redundancy check (CRC) for the data block 101001101 using the divisor 11011. 3.2. Consider the data unit to be transmitted is: 10011001 00100011 00000101, find the checksum.
