During normal system startup, a computer's basic input/output system, orBIOS, completes a hardware bootstrap or initialization. It then runs a bootloader which loads the kernel from a storage device -- such as a hard drive -- into a protected memory space. Once the kernel is loaded into ...
when an error or crash occurs, the os may display an error message or attempt to recover from the problem automatically. if recovery is not possible, the system may need to be restarted or shut down. what is kernel-level programming in an os? kernel-level programming involves writing ...

The .NET Framework is also not present in Server Core, which means there's no support for running managed code on a Server Core installation. Only native code—code written using Windows application programming interfaces (APIs)—can run on Server Core. In summary, any GUI applications that de...
The Oracle Solaris kernel is a program that manages system resources. The kernel insulates applications from the system hardware and provides them with essential...
2: Disallow kernel profiling To make the adjustedperf_event_paranoidsetting permanent, preserve it in/etc/sysctl.conf(e.g.,kernel.perf_event_paranoid = {SETTING}). perf_event_mlock_kb This controls the size of per-cpu ring buffer not counted against mlock limit. The default value is 512 ...
When a target user runs a vulnerable client program or uses a browser to open a file containing malicious code, the malicious code triggers the malware download and installation by exploiting the vulnerability. The malware is usually a small remote control tool, which is called a remote administr...
What is a Linux distribution? A Linux distribution (sometimes abbreviated as “Linux distro”) is a collection of key and optional components that combine to form a complete operating system. Generally, a Linux distribution includes core components including a bootloader, a Linux kernel, an init ...
A kernel-based virtual machine (KVM) is an example of a type 1 hypervisor. Type 2 hypervisors Type 2 hypervisors run as applications within a host OS and usually target single-user desktop or notebook platforms. With a type 2 hypervisor, you manually create a VM and install a guest OS ...
