One of your new laptop computers has a small interface that appears to support a modular connector with eight contacts. What type of connection is typically supported with this connector?
A) Printer
B) Video
C) Network
D) Modem
E) Octopus
The answer: C) Network
An RJ-45 port in a computer is used for wired Ethernet network connections. This connection is an 8P8C connection, which stands for 8 position 8 contact. This connection looks very similar to a modem connection, but a modem’s RJ-11 connector has a smaller 6P4C connector.
