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 ...
Operating System Boot
The procedure of starting a computer by loading the kernel is known as booting the system. On most computer systems, a small piece of code known as the bootstrap program or bootstrap loader locates the kernel loads it into main memory, and starts its execution. More ...
Analog to Digital Convertion with a Microcontroller
Analog-to-digital conversion (or A/D conversion), is an electronic process that converts a continuously variable signal into a digital signal (expressed as a string of 1s and 0s). More ...
Operating System Memory Allocation Methods
Operating System Memory Allocation is the process of assigning blocks of main memory to various running processes and to move processes back and forward between the main memory and disk. More ...
AMD's Phenom Processor
Since 2005 AMD has used the Athlon name for their processors. This changed in 2007 when they released their new processor called Phenom. So we must ask the question; what is the difference between the Athlon and the Phenom? 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 ...
Operating System Memory Management
Computers must keep several programs in memory, creating a need for memory management. Many different memory-management schemes are used. The operating system Keeps track of which parts of memory are currently being used, and moves data into out of memory, and allocates and deallocates memory as required. 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 ...
Microprocessor Registers
To a large extent the operation of a microprocessor involves loading, transferring, and manipulating the contents of registers. In this article you learn about the functions, and purposes of the register set of the Intel 8086 microprocessor. More ...
Pentium P5 Processor
The Pentium P5 processor was introduced in 1993 was the first superscalar processor. It featured two integer pipelines and a pipelined floating-point unit. This article describes other innovations introduced in the P5. 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 ...
Change Raspberry Pi Default Configuration
If you are a US user of the Raspberry Pi, you will discover that when you type, the characters displayed do not match our keyboard. When you type [shift][#] instead you get the British pound symbol. This is because Raspbian (and NOOBS) defaults to UK keyboard settings. More ...
