An RJ45 (Registered Jack 45) adapter is a device that allows connections to be made between devices that use Ethernet ports. It can be used to convert an Ethernet port to a USB or HDMI port, or vice versa. RJ45 converters are commonly used in computers, laptops, and gaming consoles.
RJ11 connectors are commonly used for connecting telephone lines and are widely recognized for their small, modular design. They are standard for landline telephones in homes and offices, connecting the phone to the wall outlet or the telephone network. Additionally, RJ11 connectors can also be used in some low-speed data transmission applications, such as with fax machines or modems.
