A "USB extension 2.0" is a cable that extends the reach of a USB connection, typically used to connect USB devices to a computer or hub at a distance greater than the standard USB cable length allows.

A VGA (Video Graphics Array) cable is a type of connector primarily used to transmit video signals from a computer or other compatible device to a display, such as a monitor or projector. It typically consists of a cable with a 15-pin connector on each end, though there are variations depending on the specific device and its ports. VGA cables are commonly used for connecting desktop computers, laptops, and other devices to monitors, especially older models that may not have newer connection types like HDMI or DisplayPort. However, VGA is becoming less common as newer digital connection standards offer better quality and performance.

A USB male to male cable 2.0 is a cable with USB Type-A male connectors on both ends. These cables are designed to connect two USB Type-A ports, typically found on computers, hubs, or other USB devices. The "2.0" designation indicates that the cable follows the USB 2.0 specification, which supports data transfer rates of up to 480 megabits per second (Mbps). It's essential to note that male-to-male USB cables are not as common as other USB cable types because connecting two host devices directly can cause issues and is generally not recommended. However, they can be used in specific scenarios, such as connecting two computers for data transfer or connecting certain specialized devices. Always ensure you're using cables appropriately to avoid damaging devices or causing data loss.

An "8-pin male to 8-pin female power line" is a cable used to deliver power between components in a computer or electronic device. The male end typically plugs into a power supply unit (PSU) or motherboard connector, while the female end connects to a component such as a graphics card or CPU. These cables are commonly used for delivering power to high-performance components that require additional power beyond what the motherboard can provide.

The cable you're describing is commonly known as a "USB 3.0 Micro-B to USB-A cable." This cable is used to connect external hard drives or other devices with a USB 3.0 Micro-B port to a computer or other host device with a USB Type-A port. Alternatively, you might also hear it referred to as a "USB 3.0 Micro-B cable" or simply a "USB 3.0 Micro cable." These cables are designed for high-speed data transfer and are commonly used with portable external hard drives or certain smartphones and tablets.
