1、宽带是一种相对的描述方式。带宽,是一种单位。
2、带宽是量词,指的是网速的大小。 宽带是名词,说明网络的传输速率也很高 。
3、宽带是一种相对的描述方式,包含带宽的概念,频率的范围愈大,也就是带宽愈高时,能够发送的数据也相对增加。即:宽带是一种业务,带宽是传输速度。
宽带:在数字通信中通常指64kbit/s以上信号的带宽。
窄带:在数字通信中通常指64kbit/s以下信号的带宽。
1B=8b //1字节=8位1KB=1024B1MB=1024KB1GB=1024MB
通过电脑一些软件也是可以测网速的例如:360 电脑管家等
4、宽带是描述信号或者电子线路包含或能够同时处理较宽的频率范围,带宽是标识总线和内存性能的指标之一。
5、宽带是动态概念,带宽是固定的具体概念。
上行带宽:也就是上传速度,即指服务器上传文件的速度,理论上一般是带宽峰值的8/1左右,实际会因为网络因素会有一些相应的损耗。
下行带宽:即指服务器下载文件的速度,这个应该很好理解。
国内三大运营商电信、网通、移动,家用宽带100M和服务器带宽100M的区别在于:
用户体验家用宽带100M可能是一片区域公共使用(所以会出现用网高峰期),
服务器用的带宽是单独使用(等于一个人独享100M);服务器是直接通过运营商对接(所以网络速度会非常的快,可以持续性的输出100M),而家用是需要通过运营商到软件后服务器再到家用带宽,这速度就显而易见了。
家用带宽一般只有下行带宽,运营商基本不会为家用配置上行,某些专线家用宽带除外。
在带宽的选择上,我们只需要考虑到自身的程序或者网站的数据内容大小,访问流量的人数等原因来做选择。
