To build an ethernet, you need cables and the money to pay for them. A particularly popular type of ethernet cable is called Cat5. Search the Internet for the best prices for an ethernet Cat5 cable. Study the results, and select five that might be useful. Create a table with headers for columns containing the online page address, product name, cable length, price, and a reason for including each one in the table. Select cables that could be used in a network, not just around the home. Organize the table with your first choice at the top.
Give the table to your teacher.
