Examples of privileged instructions used by 8085 processor?
There is no protected mode in the 8085 microprocessor, therefore, there are no instructions that are considered privileged.
Which router mode is accessed by entering the enable mode?
privileged EXEC
Which command do you enter in privileged EXEC mode to list the command options?
In privileged EXEC mode, you can enter the command ? to display a list of available command options. This command will show you all the commands that can be executed in the current context. Additionally, you can type the first few letters of a command followed by ? to see the specific options or parameters available for that command.
Explain the difference between user EXEC and privileged EXEC modes?
Privileged mode has access to the entire router or switch configuration. User EXEC mode only has limited options. Specifically, to do any configuration changes, you need to enter privileged mode first.Privileged mode has access to the entire router or switch configuration.

Why privilege instruction are not executed by user mode?
Privilege instructions are not executed in user mode to maintain system security and stability. User mode is designed to restrict access to critical system resources and hardware to prevent accidental or malicious interference. If user applications could execute privilege instructions, it could lead to system crashes, data corruption, and security vulnerabilities. Thus, such instructions are only allowed in kernel mode, where the operating system has full control over the hardware and system resources.
What is the router prompt for the privileged EXEC mode?
# or Router#
Which keystrokes can be used to return to privileged mode from the interface configuration mode?
ctrl-p
What does privileged mode means in arm processor?
Privileged mode in an ARM processor refers to a state of operation where the CPU has access to all system resources and can execute sensitive instructions that control hardware and manage memory. This mode is typically used by the operating system's kernel to perform critical tasks, such as managing interrupts and accessing protected areas of memory. In contrast, user mode restricts access to certain instructions and resources to ensure system stability and security. Transitioning between these modes is essential for maintaining system integrity and enforcing security policies.
Does a privileged instruction involves a Context Switch in Unix?
In any environment, in order to execute a privileged instruction you have have to switch from user mode to kernel mode, hence a context switch.
Which prompt is associated with the privileged exec mode?
R1#
What is the difference between the kernel and the user?
Kernel mode is considered a 'privileged' mode, meaning that code executing in that mode can have access to any part of the system, memory, devices, etc. There are no limitations on what it can do. User mode only allows certain operations. Anything requiring any amount of privileged must request the kernel to do things on their behalf. User mode is not a privileged mode and is therefore restrictive in terms of accessing memory, devices, etc.
Which router mode is accessed by entering the enable command?
privileged EXEC
