# System services and daemons Domain | Improvement ------------------- | ----------- Platform-Services-1 | SystemD ? Platform-Services-2 | Secure daemon ? ## Tools - **connman**: An internet connection manager designed to be slim and to use as few resources as possible. It is a fully modular system that can be extended, through plug-ins, to support all kinds of wired or wireless technologies. - **bluez** is a Bluetooth stack. Its goal is to program an implementation of the Bluetooth wireless standards specifications. In addition to the basic stack, the `bluez-utils` and `bluez-firmware` packages contain low level utilities such as `dfutool` which can interrogate the Bluetooth adapter chipset in order to determine whether its firmware can be upgraded. - **gstreamer** is a pipeline-based multimedia framework. It can be used to build a system that reads files in one format, processes them, and exports them in another format. - **alsa** is a software framework and part of the Linux kernel that provides an **API** for sound card device drivers.
