What Is Smartbyte and What Does It Do?
SmartByte is an application that comes preinstalled on many modern Dell machines, which prioritizes data packets to speed up entertainment and communication applications and services such as streaming video, web browsing, and video chat. SmartByte works by prioritizing outgoing data packets, ordering them so that data packets for latency-sensitive applications and services leave your machine first, causing packets for those applications and services also to return first, which results in a noticeable cumulative effect of reducing buffering when streaming video, as well as quicker web browsing and smoother video chat. SmartByte can only be installed on specific Dell machines on which it comes pre-installed. If you are experiencing problems with SmartByte on your Dell, the first step in troubleshooting is updating the software.
