Watch L1.10 first User vs Kernel or read the lines below :
User Mode Vs Kernel
Example Bank : We are users (customer) over there, we make calls & the bank employee act as a Kernel which responds to our call and executes our request.

00:02 System calls shift from user mode to kernel mode.
01:26 System calls are used to access devices and resources through the kernel.
02:32 Operating systems use system calls indirectly through APIs and local libraries
03:57 Programs become processes in operating system when in running mode.
05:15 System calls are used for file and device related operations in operating systems.
06:39 System calls in operating system are used to access process-related information and system's time, date, and data.
07:55 System calls are used for process control and synchronization
09:06 System calls in operating system include inter-process communication and protection/security related calls
