What You Need To Know About Server Memory
DDR is Double Data Rate which is what all memory is now. Since DDR came out it's gone through a few generations DDR, DDR2, DDR3 and now DDR4. These different generations of memory have different peak transfer rates. More ...
MPEG4, H.264, MJPEG Compression for DVR Recording - What's the Difference?
The main objective of Video compression is to have the smallest file size possible while still preserving good video and audio quality. MPEG4, H.264, and MJPEG are three DVR CODECs that aim to compress the videos for transferring purposes. Each of these formats have their own strengths and weaknesses. More ...
Understanding Computer Memory
Understanding computer memory is important because your computer's memory is where the action is. Sure your computer's central processing unit (CPU) may be the computer's brain, but what good is a brain without memory? More ...
How a laser Printer Works
Laser printers work by using a laser beam to transfer an image to an electrically charged, photo-sensitive drum. The charge on the drum attracts toner ink, which is transferred to the paper. The primary steps in the laser printing process are listed below. More ...
PC Sound Circuitry
Actual physical sound is an analog phenomenon while the computer is digital. To output a sound stored on a computer disk to a speaker the sound circuit uses a digital-to-analog converter. Sound input to the computer for recording uses an analog-to-digital converter. So PC sound circuitry is primarily an AD/DA-converter or a "coder/decoder", usually shortened to "codec". More ...

Power Supply Form Factors
The shape and physical layout of a power supply is called its 'form factor'. Power supplies come in several industry standard form factors. Power supplies with the same form factor are physically interchangeable. More ...
Rambus DRAM (RDRAM)
Rambus DRAM (RDRAM) is a proprietary memory technology, designed by the Rambus Corporation, that is found in some Pentium III and Pentium 4 systems built between 2000 and 2002. When it was introduced it run at faster speed than conventional SDRAM. When DDR SDRAM was released, RDRAM became obsolete. More ...
What is USB OTG?
USB is wonderful because it allows you to connect and disconnect devices from the computer without rebooting the computer. However, wouldn't it be even more wonderful if two USB devices, like a digital camera and a storage device could connect to each other directly? That's what USB On-The-Go (OTG) does. More ...
Hard Drives - ATA versus SATA
with data rates hitting the 133MB / sec mark the parallel ATA standard is maxing out, thus industry leaders got together and came up with a new standard known as Serial ATA (SATA). More ...
General Overview Of Motherboards
Everyone hears the term motherboard and wonders exactly what it is? The motherboard will contain connection points for your CPU (Central Processing Unit), Hard drive, RAM (Random Access Memory), Video Card, and Power Supply. More ...
The Master Boot Record (MBR)
The Master Boot Record, created when you create the first partition on the hard disk, is probably the most important data structure on the disk. It is the first sector on every disk. The location is always track (cylinder) 0, side (head) 0, and sector 1. More ...
