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 ...

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 ...

Digital Logic Semiconductor Families
logic family refers to the way the semiconductors are designed to create gates. The first highly popular logic family, available in 1964, was TTL (Transistor-Transistor Logic). More ...

Introduction to Microprocessor Programming
Assembly language involves using instructions that are mnemonics called opcodes, along with values and/or addresses in hexadecimal notation. To make learning as easy as possible, we'll first learn how to program a simple microprocessor, the 6502. 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 ...

Introduction to Boolean Algebra
Boolean algebra is a system of mathematics in which the values of the variables can take on only one of two values, either 0 or 1. Similar to regular algebra, Boolean algebra can be used to simplify a mathematical expression. Since computer logic is also a system in which the values of the inputs and outputs can take on only one of two values, Boolean algebra can be used to simplify logic circuits. 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 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 ...

Oscilloscope Required for Serious Digital Electronics Work
The oscilloscope is an instrument that displays digital signals on a line graph with time on the horizontal axis and voltage on the vertical axis. It will be difficult to do digital logic design without the use of an oscilloscope. More ...

The Android Operating System
Android os is similar to Apple ios in that it is a layered stack of software that provides a rich set of frameworks for developing mobile applications. At the bottom of this software stack is the Linux kernal. More ...

Intel's Dual-Core Core i3 Processor
Core i3 is an entry-level 2-core processor using the 32nm Westmere micro-architecture. With a Thermal Design Power (TDP) of 73 watts, the i3-530 is a cool-running chip that doesn't gobble loads of electricity, so those looking for a power-efficient, quiet machine will be happy with it. More ...

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 ...
