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 ...
Digital Logic Levels and Transfer Characteristics
A digital system uses discrete logic levels, 0 and 1, while the real world is a continuous range such as a voltage from 0 to 5. To make design easier, engineers view the system in the abstract. 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 ...
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 Use of SOI (Silicone on Insulator) Wafers in MEMS (Micro-Electro-Mechanical Systems) Production
The main advantage of Silicone on Insulator (SOI) technology is that they enable the manufacture of smaller devices. The manufacturing process optimizes the efficiency of transistors and allows chips to be packed close together, resulting in a greater yield per wafer. 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 ...
Expanding the Resources of Microcontrollers
In some cases it is possible that the internal resources of a microcontroller are insufficient. The solution to these situations is to add external components by creating an expanded microcontroller structure. 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 ...
Intel Celeron D Processor
The Celeron processor is a budget processor offering moderate performance at an affordable price. The Celeron processor is suitable for use in notebook and desktop computers running home-office applications and providing access to the Internet. More ...
Factors in Choosing an Oscilloscope
An oscilloscope is an instrument used to display the waveform of electronic signals. It draws a graph of the voltage as a function of time. A digital oscilloscope can also store waveforms and perform mathematical analysis of the waveform. More ...
How Computer Chips are Made
The oxygen is removed from silica by heating it with carbon. A tiny seed of silicon is then dipped into molten silicon. As the tiny crystal is slowly lifted out of the crucible silicon crystallizes around it. More ...
Logical Versus Physical Memory Addresses
Computers use logical and physical addresses to access memory locatiuons. The CPU generates logical addresses. At run-time the Memory Management Unit (MMU) maps logical addresses to physical addresses. More ...
