Virtual Memory and Memory Paging
In the early days of computers, memory chips were small capacity, scarce, and expensive. Because of this a memory management scheme called paging was invented. More ...
How Computer Memory Works
Every program being executed and every piece of data being manipulated must be copied from a storage device, such as a magnetic disk, into main memory. It's important to understand the basic types of memory. More ...
The Evolution of Hard Disk Bit Recording
Hard drive technology has continuously improved over the decades, that includes higher storage capacity performance. Part of this improvement has been higher access speeds, but most of the higher storage capacity has been the result of changes in the bit recording methods. 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 ...
First-Come, First-Served 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 first-come, first-served scheduling. More ...
Simplified Windows Architecture Overview
A simplified overview of the Windows operating system architecture divides it into user-mode and kernel-mode components. More ...
The Microcontroller Interrupt System
Events related to peripheral interfaces are asynchronous to the program running on the CPU. The interrupt mechanism allows an external event to temporarily put the normal execution of the microcontroller on hold and force the execution of a specific subroutine. More ...
Using The I2C Bus
The I2C bus is used for communications between individual integrated circuits located on the same PCB. The I2C protocol supports multi-master, multi-slave communication, which means you can add a lot of functionality to your design. More ...
Microcontrollers
A microcontroller is an IC that contains a microprocessor as well as RAM, ROM and general I/O ports. Engineers design microcontrollers into specific-purpose devices such as microwave ovens, cars, washing machines, refridgerators, and even space probes. 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 ...
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 ...
