Modify final. sh so that if you enter an argument on the command line called non_student_accounts you will display the number of accounts on the system that are not related to a student. Student accounts have a home directory in /home/student. Display the results with the following message. There are XX non-student accounts on YYY. Replace XX with the number of non-student accounts. Replace YYY with the hostname of the system. This information will come from a Unix/Linux command. Example: $ ./final. sh non_student_accounts Tim McGowen Mon May 20 09:58:28 PDT 2013 There are 17 non-student accounts on xyz. In the display above 17 and xyz are just examples. Not the correct answer. Test your script so that the non_student_accounts argument works correctly. When it does, continue.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
