These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).

What is the difference between micro kernel and kernel?
Compared to a typical kernel, a microkernel is compact, performing only the basic functions universal to all computers. Designed to be integrated into different operating systems, a microkernel works with OS-specific servers that provide higher level functions.
What are the two modes of kernel?
User Mode is a restricted mode, which the application programs are executing and starts. Kernel Mode is the privileged mode, which the computer enters when accessing hardware resources. User Mode is considered as the slave mode or the restricted mode.
What is a DMA threat?
A DMA Attack, short for “direct memory access” attack, is when an attacker accesses a computer via ports on the computer which grant direct memory access to high-data-transfer-speed devices. Normally, memory access is strictly managed by the operating system.

What are user and kernel modes?
In kernel mode, the program has direct and unrestricted access to system resources. In user mode, the application program executes and starts out. In user mode, a single process fails if an interrupt occurs. Kernel mode is also known as the master mode, privileged mode, or system mode.

What is monolithic and micro kernel?
A microkernel is a kernel type that implements an operating system by providing methods, including low-level address space management, IPC, and thread management. On the other hand, a monolithic kernel is a type of kernel in which the complete OS runs in the kernel space.
Is Android a micro kernel?
Microkernels tend to have a smaller amount of a shared code and communicate between the components of the kernel using a fast message passing mechanism. Since the default android kernel is derived from the Linux kernel, it is safe to say that the Android kernel is also a monolithic kernel.
