Operating System Memory Page Sharing
In a paged environment sharing of memory among processes provides numerous benefits including sharing non-self-modifying reentrant code and interprocess communication. More ...
Operating System Memory Paging Hardware Support
Paging is a memory management scheme that involves breaking physical memory into fixed-sized blocks and breaking logical memory into blocks of the same size called pages. When a process is to be executed, its pages are loaded into any available memory blocks. More ...
Multithreaded Programming Process' and Threads
A process generally has a complete, set of private resources, each process has its own memory space. Threads exist within a process, every process has at least one. Threads share the process's resources, including memory and open files. More ...
Capacitors in AC Circuits
In an AC circuit capacitors exhibit a property similar to resistance called reactance and cause a phase shift between votage and current. The vector sum of resistance and reactance in an AC circuit is called impedance. More ...
Microcontroller's Parallel I/O System
The most common way for microcontrollers to interact with the outside world is the The digital I/O lines. More ...
Inductors in DC Circuits
An inductor is constructed with a coil of wire. When connected to a voltage source, an inductor resists a change in current flow as it stores energy in its magnetic field, and it can return that energy to the circuit if desired. More ...
Operating System Process Scheduling Queues
The objective of multiprogramming is to have some process running at all times, to maximize CPU utilization. To meet these objectives, the process scheduler selects a process from a queue for execution on the CPU. More ...
Windows Operating System Services, Functions, Routines, Processes, Threads, and Jobs
The Windows operating system uses many confusing terms. This article explains the meaning of the terms: Services, Functions, Routines, Processes, Threads, and Jobs. More ...
CPU Process Scheduling
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer more productive. More ...
AMD's Phenom Processor
AMD released the first Phenom processor in 2007. Unlike Intel's Core 2 Quad processors, which are a multi-chip module (MCM) design, AMD's Phenom processors had all cores on the same silicon die. More ...
Introduction to Computer System Main Memory Operation
The CPU can be shared by a set of processes. Using CPU scheduling, we can improve the utilization of the CPU and the speed of the computer's response. To realize this increase in performance, multiple processes must be kept in memory. More ...
Basic Computer Architecture
Computers today, even that PC on your desk are unbelievably complex. You can't understand computers without an understanding of the basics. In this article I explain basic computer architecture in simple, basic terms. More ...
