However, some flash memory drives can use pin 20 as VCC_in to power the drive without requiring a special power cable; this feature can only be used if the equipment supports this use of pin 20. [32] Pin 28 Pin 28 of the gray (slave/middle) connector of an 80-conductor cable is not attached to any conductor of the cable.
Thus, USB cables have different ends: A and B, with different physical connectors for each. Each format has a plug and receptacle defined for each of the A and B ends. A USB cable, by definition, has a plug on each end—one A (or C) and one B (or C)—and the corresponding receptacle is usually on a computer or electronic device.
If the smaller side of this cable is plugged into a "powered" ESATA port, providing both 12 V and 5 V, then the wide end may be plugged into a 2.5" or 3.5" SATA hard drive, supplying the bare drive with both signal and power. The small 2.5" drive will get signal and power at 5 V, which is all that the smaller drive requires, and which the ...
eSATA does not supply power to external devices. This is an increasing disadvantage compared to USB. Even though USB 3.0's 4.5 W is sometimes insufficient to power external hard drives, technology is advancing, and external drives gradually need less power, diminishing the eSATA advantage.
Micro-A adapters allow for connection to standard-A plugs, as used on fixed or standard devices. An OTG product must have a single micro-AB receptacle and no other USB receptacles. [5] [6] An OTG cable has a micro-A plug on one end, and a micro-B plug on the other end (it cannot have two plugs of the same type).
Microarchitecture, also known as computer organization, refers to high-level hardware questions such as the design of the CPU, memory, and memory interconnect. [26] Memory hierarchy ensures that the memory quicker to access (and more expensive) is located closer to the CPU, while slower, cheaper memory for large-volume storage is located ...

USB-C plug USB-C (SuperSpeed USB 5Gbps) receptacle on an MSI laptop. USB-C, or USB Type-C, is a 24-pin connector (not a protocol) that supersedes previous USB connectors and can carry audio, video, and other data, to connect to monitors or external drives. It can also provide and receive power, to power, e.g., a laptop or a mobile phone.
