Our Kernel, inside the OS consists of many things like...system tools,spreadsheets,email....etc..different types of applications....now when a user wants to access one of such application....then that signal is required to be sent to CPU..i.e at the hardware level...so that the respective application can be started.. so...in order to take that signal to CPU a system call is used..hence we can say a set of commands which are used to send signal to the kernel and then that kernel can indirectly connect the h/w and user...a system call is used....
Thanks...Hope i helped...
