The Linux Kernel is designed based on the UNIX kernel. It is highly versatile and can be deployed on both traditional computer systems such as personal computers and servers, as well as on devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs, PVRs and NAS appliances.
