#usb type b

USB (Universal Serial Bus) is an interface with which you can connect different types of devices and peripherals to your PC such as: cameras, mice, smartphones, tablets, keyboards, external HD and more. In addition to the Plug & Play connection, literally connect and use, USB cables also provide power to the device; In the case of smartphones these are recharged when connected to the PC. USB Type A, type B and type C The smartphones have micro ports, of different types, with which the devices are recharged via PC, precisely, or with the direct connection to the electric current through a transformer. Over the years USB standards have changed from USB type A to type B, today, to USB type C. Those of type A and B have a micro version and those of type B also a mini version. The design of the USB is designed to allow a simple insertion and removal with a specific direction for insertion, excluding those of type C which, instead, can be inserted in any direction. USB type A Also known as USB Standard-A, the USB type A is the original design for the USB standard with a flat and rectangular shape. In a typical USB cable, the Type a connector, aka the A-male connector, is the end that goes into a host, such as a computer. And on a host, the USB port (or socket) where the A-male type is to be inserted, is the A-female port (valid for all types of USB). USB Type A is characterized by several versions including USB 1.1, USB 2.0, USB 3.0. A connector is always compatible with the different versions for example, an external USB 3.0 hard drive also works with a USB 2.0 port, and vice versa. USB type B Since peripheral devices vary greatly in shape and size, the type B connector and its port have many different designs. So far there are five designs for plugs and USB connectors of type B. The original standard (Standard-B): It is designed for USB 1.1 and is also used for USB 2.0. Especially for connecting large peripheral devices, such as printers or scanners to a computer.Mini-USB: Significantly smaller, mini-USB type B ports are found in older portable devices, such as digital cameras, smartphones and older portable drives. This design is becoming obsolete.Micro-USB: Slightly smaller than mini-USB, the micro-USB port type B is currently the most important USB design for smartphones and tablets.Micro-USB 3.0: This is the most used design for USB 3.0 that are on portable devices. Most of the time, type A has one end of the cable is blue.Standard-B USB 3.0: This design is very similar to the standard-B, however, it is designed to handle the speed of USB 3.0. Most of the time, both ends of the cable are blue.Maximum power Max speed inversion of power cable configuration availabilityUSB 1.1 12Mbps 2.5 V, 500ma device Host type-A and type B 1998USB 2.0 480Mbps 2.5 V, 1.8 a device Host type-A and type B 2000USB 3.0 5Gbps 5v, 1.8 a device Host type-A and type B 2008USB 3.1 10Gbps 20v, 5a bidirectional Type-C both ends, reversible plug 2015USB Type-C (or USB-C) Physically, the port and connector type C have about the same size as that of the Micro USB type B. This means that it is small enough to work even for multiple peripherals. With the Type-C, both ends of the cable are equal, allowing the plug to be reversible. There is no danger of wronging the direction of insertion. Available from 2015, USB Type-C supports USB 3.1 with a maximum speed of 10 Gbps and has a very high power, up to 20v (100w) and 5a. Considering that most of the 15-inch laptops require 60w of power, this means that in the future laptops could be equipped with power supplies as today happens with tablets and smartphones, via the small (compared to the power supplies) USB port. Actually the latest 12-inch MacBook is the first notebook that incorporates a USB type-C as a power port. The USB Type-C also allows bi-directional power, so apart from charging the device, a device may also load a host device. All this means that you can do without a series of proprietary power adapters and USB cables.
