Often referred to as “male”, as they plug into a “female” port, it is important to understand that there are two elements of USB standard to consider; the physical connector shape and the underlying protocol (speed). USB Type A High-speed (HS) uses the same wire pair, but with different electrical conventions. Lower signal voltages of −10 to 10 mV for low and 360 to 440 mV for logical high level, and termination of 45Ω to ground or 90Ω differential to match the data cable impedance.
On-The-Go Supplement 1.3 USB On-The-Go makes it possible for two USB devices to communicate with each other without requiring a separate USB host All converters and transformers will have a maximum power rating (AMPS or WATTS) so make sure that any appliance you intend to use does not exceed this rating. Dual voltage rated appliance This is the current standard, and it marries power and data delivery with display connectivity. USB-C is what you'll see on most new devices like smartphones, game controllers, earbud cases, microphones, and laptops. Its form factor is small, oblong, and reversible, so it can be plugged in either way (take that, USB-A). The port's 100-watt connection makes it perfectly suited for fast charging and data transfers, even with larger devices. Includes new USB4 Gen2×2 (64b/66b encoding) and Gen3×2 (128b/132b encoding) modes and introduces USB4 routing for tunneling of USB3.2, DisplayPort1.4a and PCI Express traffic and host-to-host transfers, based on the Thunderbolt3 protocol; requires USB4 Fabric.

The USB interface is hot-swappable (devices can be exchanged without shutting the host computer down).
eSATA, like USB, supports hot plugging, although this might be limited by OS drivers and device firmware. USB, which stands for Universal Serial Bus, refers to the system that transfers data between computers or between components within a computer, such as a keyboard or a mouse. Consisting of a type of cable and connector, many electronic devices will have a USB connection available, including in vehicles and modern workstation power systems. a b "Cables and Long-Haul Solutions".

USB provides three isochronous (fixed-bandwidth) synchronization types, [76] all of which are used by audio devices: [77] A USB system consists of a host with one or more downstream facing ports (DFP), [52] and multiple peripherals, forming a tiered- star topology. Additional USB hubs may be included, allowing up to five tiers. A USB host may have multiple controllers, each with one or more ports. Up to 127 devices may be connected to a single host controller. [53] [30] :8–29 USB devices are linked in series through hubs. The hub built into the host controller is called the root hub.Though most personal computers since early 2005 can boot from USB mass storage devices, USB is not intended as a primary bus for a computer's internal storage. However, USB has the advantage of allowing hot-swapping, making it useful for mobile peripherals, including drives of various kinds. In most modern technology devices, there will be some form of USB connection available to connect equipment. Despite supposedly being universal, there are different variations of USB types and versions; including what connectors and cables each can use.

Neither USB 1.0 nor 1.1 specified a design for any connector smaller than the standard type A or type B. Though many designs for a miniaturized type B connector appeared on many peripherals, conformity to the USB1. x standard was hampered by treating peripherals that had miniature connectors as though they had a tethered connection (that is: no plug or receptacle at the peripheral end). There was no known miniature type A connector until USB2.0 (revision 1.01) introduced one.
