在购买电脑的时候经常会提到电脑的usb接口,什么USB3.0接口和USB2.0接口?到底他们有什么区别?很多新手们不是很理解这个,只是感觉usb就是用来插U盘和一些外接设备用的。那usb2.0和3.0之间有什么区别呢?下面,小编就来跟大家讲讲电脑usb2.0和3.0的区别。
我们在组装电脑选择主板的时候,通常会看看主板是不是支持usb接口是3.0还是2.0的,USB3.0是高速接口,只有上市时间不长的主板才支持,而电脑新用户就想知道usb2.0和3.0的区别,下面,小编给大家介绍usb2.0和3.0的区别。
电脑usb2.0和3.0的有什么区别
从USB外观上来看,USB2.0通常是白色或黑色,而USB3.0则改观为“高大上”的蓝色接口。

从USB公口的外观上来看,USB3.0接口部分标记有“SS”样式,而USB2.0则只标记普通的USB通用标识。

目前,部分笔记本电脑USB接口,已同时提供对USB2.0及USB3.0的支持,我们可以通过接口颜色来区别。
从传输速率上来看,理论值:USB 3.0的传输速度是4.8Gbps,是USB 2.0的10倍。即4.8Gbps=600MB/S。
对于U盘是否支持USB3.0,我们可以通常U盘外观来区分,通常情况下USB3.0U盘将会被识别
关于usb2.0和3.0的区别,小编先跟大伙讲到这里了。
