First, the process is "created" by being loaded from a secondary storage device (hard disk drive, CD-ROM, etc.) into main memory. After that the process scheduler assigns it the "waiting" state. While the process is "waiting", it waits for the scheduler to do a so-called context switch. The context switch loads the process into the processor ...
A computer bus for attaching hardware devices in a computer. core The portion of the CPU which actually performs arithmetic and logical operations; nearly all CPUs produced since the late 2000s decade have multiple cores (e.g. "a quad-core processor"). core memory
The conversion process is referred to as assembly, as in assembling the source code. The computational step when an assembler is processing a program is called assembly time. Because assembly depends on the machine code instructions, each assembly language [nb 1] is specific to a particular computer architecture. [11] [12] [13]
A hardware interrupt occurs; for example, a key was pressed on the keyboard, or a timer runs out (used in preemptive multitasking). The stopping of one process and starting (or restarting) of another process is called a context switch or context change. In many modern operating systems, processes can consist of many sub-processes.
E-cycling, the recycling of computer hardware, refers to the donation, reuse, shredding and general collection of used electronics. Generically, the term refers to the process of collecting, brokering, disassembling, repairing and recycling the components or metals contained in used or discarded electronic equipment, otherwise known as ...
Processors based on different circuit technology have been developed. One example is quantum processors, which use quantum physics to enable algorithms that are impossible on classical computers (those using traditional circuitry). Another example is photonic processors, which use light to make computations instead of semiconducting electronics ...
An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
The software development process is noticeably different depending on the type of translator used by a developer, this of course differs from translator to translator. Stages of the development process that are influenced by a translator include the initial programming stage, the debugging stage, and most notably the execution process. Factors ...
