Capacitors in DC Circuits
A capacitor is a component that can be used to store an electrical charge. A capacitor can be used to create a timer. This time delay can be used to smooth a changing current flow in a circuit, or it can be used to absorb spikes and prevent false triggering of other components. 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 ...
Binary Number Representation and Binary Math
Computers perform all of their amazing work with only two voltage levels, one representing binary 0, the other representing binary 1. This article describes how to perform binary addition and subtraction. More ...
CPU Chip Packaging
Over the development time of the computer, several different designs of packaging for the CPU chip die have been used. Each type of packaging has its advantages and disadvantages. This article reviews some common packages that might still be in use. 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 ...
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 ...
The Many Processes of Silicon Wafer Manufacturing
A silicon wafer is a thin, circular disc used in the manufacture of integrated circuits and semiconductors. The silicon wafer manufacturing process is interesting. More ...
Operating System File Management
The operating system abstracts from the physical properties of its storage devices to define a logical storage unit, the file. The operating system maps files onto physical media and accesses these files via the storage devices. More ...
Fundamental Digital Logic Gates
All the advanced features of the most powerful computers, such as mulicore and parallel processing are done with digital logic. In this article I explain the fundamental concept of digital logic in simple and clear language so that anyone can understand it. 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 ...
AMD's Microarchitectures
A microarchitecture describes the physical features, functions, and the technology level of the processes used to manufacture the core of a microprocessor. This article describes the microarchitectures used by AMD. More ...
