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.
Establishing that a computer is frequently CPU-bound implies that upgrading the CPU or optimizing code will improve the overall computer performance. With the advent of multiple buses, parallel processing, multiprogramming , preemptive scheduling, advanced graphics cards , advanced sound cards and generally, more decentralized loads, it became ...
It was an accident of history [editorializing] that the IBM PC happened to have an Intel CPU (instead of the technically superior [3] Motorola 68000 that had been tipped for it, or an IBM in-house design), and that it shipped with IBM PC DOS (a licensed version of Microsoft's MS-DOS) rather than the CP/M-86 operating system, but these accidents ...
In order to ensure that one program cannot monopolize the computer's limited hardware resources, the operating system gives each application a share of the resource, either in time (CPU) or space (memory). [10] [11] The operating system also must isolate applications from each other to protect them from errors and security vulnerabilities in ...
Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]
Nehalem / n ə ˈ h eɪ l əm / [1] is the codename for Intel's 45 nm microarchitecture released in November 2008. [2] It was used in the first generation of the Intel Core i5 and i7 processors, and succeeds the older Core microarchitecture used on Core 2 processors. [3]

Task Manager, previously known as Windows Task Manager, is a task manager, system monitor, and startup manager included with Microsoft Windows systems. It provides information about computer performance and running software, including names of running processes, CPU and GPU load, commit charge, I/O details, logged-in users, and Windows services.
