This post describes about benefits of USB
- USB allows usage of one standard connector. No need of different types of connector like DB-9, Parallel connector. (I am talking about the older days such as 90's and still this holds good).
- USB reduces the size of connector drastically. Compared to DB-9 and parallel connector USB connector size reduced significantly.
- USB eliminates restarting the Host PC after installation of a driver when the connected device uses the standard drivers being used which are shipped as part Windows / Linux / Mac OS.
- Before USB invented, to install a new hardware onto a Windows PC, one need to restart it. USB can help the device to work without restarting it. We call it as plug and play. Buy any new USB based device such as pen drive, camera, mouse, keyboard and etc... just connect them to the USB port available on Host PC, it just works like that.
