These questions are designed to prepare you for the critical thinking required for the A+ exams and may use content from other chapters and the web. Your customer then asks you if it would be worth the investment for him to have Ethernet cabling installed to reach each of his workstations, instead of connecting them by Wi-Fi to his network. Specifically, he wants to know if that would speed up communications for the workstations. You examine his router and find that it’s using 802.11ac Wi-Fi. Would you advise him to upgrade to Ethernet? Why or why not?
a. Yes, because Ethernet is faster than 802.11ac.
b. Yes, because wired connections are always faster than wireless connections.
c. No, because installing Ethernet cabling is more expensive than the increased speed is worth.
d. No, because 802.11ac speeds are faster than Ethernet.

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)
