Starvation (computer science) In computer science, resource starvation is a problem encountered in concurrent computing where a process is perpetually denied necessary resources to process its work. [ 1] Starvation may be caused by errors in a scheduling or mutual exclusion algorithm, but can also be caused by resource leaks, and can be ...
Execution of process creation system call by a running process. A user request to create a new process. Initiation of a batch job. When an operating system is booted, typically several processes are created. Some of these are foreground processes, that interact with a (human) user and perform work for them.
Windows 2000 is the first Windows to support hibernation at the operating system level (OS-controlled ACPI S4 sleep state) without special drivers from the hardware manufacturer. A hidden system file named "hiberfil.sys" in the root of the boot partition is used to store the contents of RAM when the computer hibernates. In Windows 2000, this ...
The Pick Operating System is an integrated computing platform with a database, query and procedural operation languages, peripheral and multi-user management, and BASIC programming capabilities. Its database utilizes a hash-file system, enabling efficient data storage and retrieval by organizing data into dynamic associative arrays managed by ...
Thread (computing) In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [ 1] In many cases, a thread is a component of a process. The multiple threads of a given process may be executed concurrently (via ...
Thrashing (computer science) In computer science, thrashing occurs in a system with virtual memory when a computer's real storage resources are overcommitted, leading to a constant state of paging and page faults, slowing most application -level processing. [ 1] This causes the performance of the computer to degrade or even collapse.
Microkernel. In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).
Multithreading (computer architecture) A process with two threads of execution, running on a single processor. In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution .
