Why do we Defrag the Hard Disk?
What is Defragging? Defragging is process done to a hard disk in order to improve performance and recover some lost disk space. Defragging is an essential part of a PC's upkeep as it keeps all the data on your hard disk in an easily readable order. If a hard disk is left without defragging, then over time the disk will begin to lose performance and also slowly reduce the available capacity to data. As you will be aware if your hard disk is running slowly then this will ...
Types of Monitors
A cathode ray tube or CRT, is traditionally used in most computer monitors and the advent of plasma screens, LCD , DLP, OLED displays, and other technologies. As a result of CRT technology, computer monitors continue to be referred to as "The Tube".A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of ...
How to Upgrade Your CPU - Part 2
Now that we have talked about what CPU you should get, next is the removal and installation process of upgrading your CPU. First you need to shut down your computer completely, unplug all cables connected to it, and lay it out in an open workspace, preferably a wood table. You also will need a Philips and flathead screw driver and before you open your computer or anything, be sure to touch a metal surface to ground yourself and avoid any static electricity.
Video Card Purchases: The More You Play...The More You Pay
In case you haven't noticed, the high-end video cards are expensive with every release, and the same high-end video cards disappear from their pole position within 6 months or less due to another model replacing it. There are video card owners who feel betrayed after spending $700 on a graphics card, only to discover several months later the card can be purchased for half the amount. Are these consumers justified in being confused and at a loss for why their video card is outdated before ...

Visible Ops: Adding Realism to ITIL Process Improvement
While ITIL has provided a proven framework to assist with the increasing challenges associated with maintaining a more efficient, secure and compliant IT organization, only a handful of tools are publicly available to support the execution of ITIL-based improvement efforts. But a quick review of the Visible Ops handbook from the Information Technology Process Institute (ITPI), may give way to more tactical discussions on realistic service improvements for your ITO.
ASL ITIL for Enhanced Application Management
The emergence of ASL (Application Services Library) has spawned a potential compliment to the ITIL framework, and is catching the attention of ITSM professionals. Touted as another “standard” public domain framework sponsored by The ASL Foundation, it provides a collection of best practices for managing application development and maintenance. But how does it fit into the “big picture” of ITIL?
History of the Computer: Cooling, Part 1 of 2
We have mentioned the provisions made to provide back-up power systems involving generators and banks of batteries (see history of the computer - redundancy). You can probably tell from this that we are talking about a lot of power here.
History of the Computer: Cooling, Part 2 of 2
Computer manufacturers specified the heat load required to be handled, the required flow of conditioned air, and the temperature to be measured at the cabinet entry points. Most systems were installed on false floors, with a space of about 1 meter or 3ft below the floor. This allowed the air conditioning to be supplied under the floor, and exhausted through the false ceiling. This space was also used for cabling the systems. An air lock was often provided for entry and exit.
How to Manually Update any FireFox Extension XPI File
OpenSource is perhaps one of the greatest things about the web. Using OpenSource programs, however, can sometimes be frustrating because when some programs are updated, others are not. Usually, you will have to either wait for updates of your non-workable programs or delay the updating of other programs to retain functionality. With FireFox extensions, however, you can usually update yourself. Let me tell you how.
History of Hewlett Packard and Ink
Hewlett Packard’s tryst with ink took off when it acquired a company named F.L Mosley based in California in 1958. Mosley was manufacturing recorders and plotters for industrial applications such as continuous process monitoring systems, data loggers and the like in the 1950’s.
Getting Started With Your New Printer
If you have recently bought yourself a new printer, follow the directions in the manual for setting up cables. Put the installation CD into the CD drive and follow the set up instructions.
Compatible Cartridges and Remanufactured Cartridges
The sales of OEM cartridges have been major revenue for printer manufacturers for many years. This pattern is changing recently. Despite the steep drop of printer price, the price of OEM cartridges remains remarkably high. Many consumers are fed up with expensive OEM cartridges and look for cheap alternatives. As a result, compatible cartridges and remanufactured cartridges are becoming more popular than ever before.
What is HD DVD?
HD DVD stands for High Definition Digital Versatile Disc. It is a round and thin disc that looks almost exactly like a CD or DVD. It is actually very similar to CDs and DVDs in all aspects except one. The difference is that a HD DVD can hold much more information than the CD/DVDs of the past. The way they packed more information into the same space mainly comes from the color of the laser that is used to read the disc. HD DVDs are read by a blue-violet laser beam instead of the ...
Ad Hoc Definition
We have all heard the term ad hoc. What does this word actually mean? How do I use it properly? I have been asking these same questions for years. However, today I have decided to solve the mystery and find the ad hoc definition. I did what every inquisitive scholar does and looked it up on google. Here is what I found on the ad hoc definition. Directly translated from its Latin origin, ad hoc means "for this"—the term is generally used to imply that something is intended for a ...
New Apple Products 2006 - The Introduction of the Intel Macs
In the past two months Apple has released a number of completely new products, and more importantly has started their transition to the Intel processor. In this article I will detail the new product offerings and options available on each.
History of the Computer: Real time Systems, Part 1 of 2
We have mentioned before, in the history of the computer series, that digital computers have been developed as general purpose machines. You buy one of our systems, and you can use it to run a bank, operate the lottery, build a car, or control freight shipments for an airline.
What is Blu Ray?
Blu-Ray is the name of the technology that has been implemented for a Blu-Ray Disc. This technology is very similar to a CD or DVD, only it is far more accurate. Like a DVD, a Blu-Ray Disk is round and thin. When inserted into a Blu-Ray Player it is spun and a laser reads the information in a digital format. The difference with Blu-Ray is that it uses a more precise laser that is blue-violet in color, giving the technology its name. Using this color instead of red, gives the laser beam ...
Contrasting 802.11B and DHTs
Abstract Unified scalable algorithms have led to many confusing advances, including checksums and context-free grammar. In this position paper, we prove the study of courseware, which embodies the key principles of cryptoanalysis. We show that although the infamous collaborative algorithm for the improvement of fiber-optic cables by Raman and Thomas  runs in O( n ) time, interrupts and model checking are regularly incompatible.Table of Contents1) Introduction

Comparing Evolutionary Programming and Extreme Programming with Mum
Comparing Evolutionary Programming and Extreme Programming with Mum by Marshall Kanner AbstractThe implications of peer-to-peer modalities have been far-reaching and pervasive [36,13,37,7,37]. In fact, few system administrators would disagree with the emulation of IPv4 . Our focus in this work is not on whether cache coherence and 16 bit architectures are rarely incompatible, but rather on describing a novel heuristic for the study of DHCP (Mum).Table of Contents1) ...
History of the Computer - Memory Error Correction Codes Part 1 of 2
We have mentioned before, in the history of the computer series, that various forms of error correction are used, in cases where the medium is unreliable. This applies mainly to magnetic tape and disks. The magnetic coating on the recording surfaces is subject to wear, various codes such as CRC (Cyclic Redundancy Check) have been developed. Data transmission now also uses error correction, previously error detection would cause a re-transmission.
