Shortest-Job-First CPU Scheduling Algorithm
CPU Scheduling deals with the problem of deciding which of the processes in the ready queue is to be alocated the CPU. There are many different CPU scheduling algorithms. In this article we describe shortest-job-first scheduling. 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 ...
Program Flow Charting
Depending upon the language used, program code my be difficult for humans to read and understand. However, one type of programming that is very easy to understand is flow charting. More ...
The Use of SOI (Silicone on Insulator) Wafers in MEMS (Micro-Electro-Mechanical Systems) Production
The main advantage of Silicone on Insulator (SOI) technology is that they enable the manufacture of smaller devices. The manufacturing process optimizes the efficiency of transistors and allows chips to be packed close together, resulting in a greater yield per wafer. More ...
Simplified Windows Architecture Overview
A simplified overview of the Windows operating system architecture divides it into user-mode and kernel-mode components. 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 ...
Introduction to the Raspberry Pi
The Raspberry Pi is a tiny bare-bones computer motherboard. You can easily make it into a Linux PC by connecting your own keyboard, mouse, and display. More ...
Operating System Process Control Block
An Operating System Process is a program in execution. It includes the value in the program counter and in the processors registers. A process also includes a stack, data section, and a heap. Although two processes may be associated with the same program, they are considered two separate execution sequences. More ...
Difference between Stack, Heap, and Queue
Stack, heap, and queue are ways that elements are stored in memory. Stack elements are added to the top of the stack, and removed from the top of the stack. The mnemonic LIFO is used to describe a stack (Last-In-First-Out). With a queue, the first one in is the first one out. The mnemonic FIFO is used to describe a queue. A heap is an area of memory where elements can be stored and removed in any order. 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 ...
Intel's Sandy Bridge Micro-Architecture
"Sandy Bridge" is Intel's code name for a new cpu core microarchitecture. It introduces a few new or improved features. The memory controller, the PCI Express controller, and video circuitry are all located within the processor die and the new ring architecture uses a Last Level Cache between the CPU and graphics cores. More ...
The Computer's Chipset
A computers memory and peripheral ports connect through two highly integrated chips called simply the chipset. The chipset consists of a northbridge chip and a southbridge chip. More ...
