Write a user dened matlab function that converts integers written in decimal form to binary form. name the function b = bina(d), where the input argument d is the integer to be converted and the output argument b is a vector with ones and zeros that represents the number in binary form. the largest number that could be converted with the function should be a binary number which 16 ones. if a large number is entered as d, the function should display an error message. use the function to convert the following numbers:

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).
