ITEC 3100 – Introduction to Networks Professor: Dr. Binh Tran Lab 1b: (Use a different color font for your written answers) Q1. What are the speed ranges for the 3 types of harddrives? Mechanical: 50 MB/s – 150 MB/s SSD: 300 MB/S - 575 MB/S M.2 drives: 1500 MB/S -3800 MB/A Q2. If the M.2 NvME drive is so fast why is it not recommended on all systems? It’s new technology so not all motherboards have M.2 slots & support NVMe technology. Q3. Explain the difference between an IP address and a MAC address. MAC address and IP address are used to uniquely identify a machine on the internet. MAC address is provided by the chip maker. MAC address ensures the physical address of the computer. It identifies the devices on a network. MAC address can’t be changed or easily found by third party. IP address is provided by the internet service provider. IP address identifies the connection of network with that device take part in a network. 1

I.e. file sharing, printers, internet connection, email, video conference and etc. Cloud-based networking : gives user access to networking resources through a third-party provider operating interconnected servers. Using Wide Area Network (WAN) or other internet-based technology, it helps distribute content quickly and securely. Q8. Insert screenshot of your HDD test speed here:
