Operating System Processes
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. More ...
Electronic Circuits
There are five types of circuits; open, short, series, parallel, and series-parallel. Using Ohm's law, along with the reciprocal formula to calculate the equivalent resistance of resistors in parallel, you can calculate the voltage or current in any part of a circuit. More ...
Online Color Coded Resistor Calculator
To determine the resistance value of a color-coded resistor, select the colors matching each band from the drop-down lists. 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 ...
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 ...
The Motherboard Chipset
Because the chipset dictates the bus speed, type and amount of memory, and the type and number of I/O ports, much of a computer's performance is determined by its chipset. More ...
Dynamic Loading of Program Routines and Dynamically linked libraries (DLLs)
In order to execute, it is not necessary for an entire program to be in physical memory. With dynamic loading, a routine is not loaded until it is called. More ...
Basic Decoder Circuitry
A microprocessors is a circuit that reads and execute program instructions called opcodes. A decoder is a circuit that converts an opcode into signals tused to control the circuitry of the microprocessor to enable it to perform the instruction. More ...
Integrated Circuit Design Flow
The process of integrated circuit design can be divided into stages: system design, logic design, circuit design, layout design, fabrication and testing. More ...
Pi-Top kit - Build Your Own Laptop
Computer hobbyists has been building their own desktop computers since the mid 1980's, but I know of no laptop kits, until now. The Pi-Top is a kit that lets you build your own laptop. More ...
Operating System Memory Paging
Paging is a memory management scheme that permits a process's physical address space to be noncontiguous. More ...
Data Structures - Linked List, Stack, Queue, and Tree
An array is a simple data structure in which each element can be accessed directly. But what about storing an item whose size may vary? And what about removing an item if the relative positions of the remaining items must be preserved? In such situations other data structures may be needed. More ...
