What are kernel level threads?
KERNEL In computing, the kernel is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components).
What does the term kernel in computer software mean?
In computing, the kernel is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level.
What are the four types of Rootkit?
The four types of rootkits are: User-mode Rootkits: These operate at the application layer, modifying user-level applications and system calls to hide malicious activities. Kernel-mode Rootkits: These have deeper system access, modifying the operating system's kernel to hide their presence and manipulate system operations. Bootkits: These target the system's boot process, infecting the bootloader to gain control before the operating system loads. Firmware Rootkits: These reside in firmware, such as BIOS or UEFI, allowing them to maintain persistence and control over the hardware, even after the operating system is reinstalled.

A driver that has full access to all hardware and the memory of the computer has what type of security level?
Kernel mode By A Raju
Is user level threads are transparent to kernel level threads?
user level theads are not tranparent to kernel level threads.
What are the three layers of an operating system?
Operating systems are designed with a series of layers. The three main layers are the user level, the system level including administration, and the kernel level that includes hardware.
Why must a computer start in kernel mode when power is switched on?
Because a kernel is the main component of most computer operating system,it is bridge between application and the actual data processing done at hardware level .The kernel responsibility include managing the system resources. sanjjit------thank you
What is the Linux kernel?
The Linux kernel is the central component of the GNU/Linux operating system. The kernel is the lowest level of interaction between the hardware and the operating system. Individual applications are at a higher level. The kernel along with supporting applications make up the operating system.
Example for user level threads and kernel level threads?

How are rootkits different from other forms of malware?
Rootkits are a specific type of malware designed to gain unauthorized access to a computer system while remaining hidden from detection. Unlike other forms of malware, which may be overt in their actions (like viruses or ransomware), rootkits focus on stealth and persistence, often modifying the operating system or software to conceal their presence. This makes them particularly challenging to detect and remove, as they can operate at a low level, intercepting calls between the operating system and applications. Their primary goal is to maintain control over a system without alerting the user or security tools.
Kernal memory is what?
The kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components)
