Plugs, Connectors, Ports, and Jacks: The Differences

Plugs, connectors, ports, and jacks all have a role to play within an electrical system. They are commonly used in conjunction with one another, and the intricacy of some electrical systems can make it difficult to fully understand the differences between these components. In this blog, we will discuss unique characteristics of each and hopefully clear up any confusion you may have about their differences.

The plug is part of a cable that connects into a port. Plugs always connect to something else; for example, the most common plug is the power plug that connects your computer and monitor to a power source, allowing it to turn on. When a plug is properly wired and secured in the wall, devices such as appliances, lamps, or other electronics can be plugged into the outlet. When the metal prongs of a plug are inserted into the plastic outlet, a conductive connection is created between the device and the source's electrical wiring. This connection subsequently permits the free flow of electrical wiring into the device, providing the required powered for the device to function.

A connector is the end of a plug, jack, or edge of a card that integrates into a port. For example, a PC development card features a connector that enables the card to be associated with an opening on the motherboard. In terms of links, the connector is the point of the cable that connects into a port, such as the endpoint of a USB cable that interfaces with a USB port. Connectors are sometimes referred to as physical interfaces. A connector has two ends, one of which connects to a port on the framework unit while the other connects to a port on the fringe. They are used to join two unique devices. Certain types of connectors have locking features to prevent accidental disconnection or poor ecological fixing. Locking systems include screw bolting, flip locking, and blade locking.

A port is a point at which a peripheral device is attached or communicates with a framework unit such that the peripheral device is able to send or receive data to and from the PC. An independent device, such as a console, screen, printer, mouse, or amplifier, is commonly joined to a frame work unit by a cable to the port. Ports are commonly confused for jacks and, though they are similar, the two are different things. On a PC, there are ports located on the front and back of the framework. On laptops, as well as netbooks and tablets, the ports are located on the back, front, and occasionally the sides. All ports will feature either gaps or a space that coordinates the plug or card that is to be attached into the port.

Lastly, a jack, similar to a port, is an opening or other connection that enables an excellent fitting to be affixed to the jack. A jack is one of the most reliable methods of connection. They are commonly viewed as the fixed portion, or the part that is housed on a gear that doesn’t move to that extent. Whether you need a plug, connector, port, or jack, it is important to get them from a trusted source like One Click Aviation.
