Kernel. In Windows NT operating systems, the System Idle Process contains one or more kernel threads which run when no other runnable thread can be scheduled on a CPU. In a multiprocessor system, there is one idle thread associated with each CPU core. For a system with hyperthreading enabled, there is an idle thread for each logical processor.
Uptime is a measure of system reliability, expressed as the period of time a machine, typically a computer, has been continuously working and available. Uptime is the opposite of downtime. Htop adds an exclamation mark when uptime is longer than 100 days. It is often used as a measure of computer operating system reliability or stability, in ...
CPU color time for program P1. CPU time (or process time) is the amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program or operating system, as opposed to elapsed time, which includes for example, waiting for input/output (I/O) operations or entering low-power (idle) mode.
High availability (HA) is a characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period. [1] Modernization has resulted in an increased reliance on these systems. For example, hospitals and data centers require high availability of their systems to perform routine ...
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other ...
The Sun Microsystems UltraSPARC processor is a type of RISC microprocessor. In electronics and computer science, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set computer ...
For smartphones and other mobile devices, Android leads with 70.87% market share, and Apple's iOS has 28.39%. [2] For desktop computers and laptops, Microsoft Windows is the most used at 72.22%, followed by Apple's macOS at 14.73%, desktop Linux at 3.88%, and Google's ChromeOS at 2.45%.
A translation lookaside buffer (TLB) is a memory cache that stores the recent translations of virtual memory to physical memory. It is used to reduce the time taken to access a user memory location. [1] It can be called an address-translation cache. It is a part of the chip's memory-management unit (MMU).
