Build Your Own ComputerWritten by George W. Cannata
Build Your Own ComputerIf I cand do it so can you Written by: George W. Cannata I’m eighty-one years old and I bought my first computer six years ago. When I bought it I hardly knew how to turn it on. I consider myself still a Newbie as I’ve barely scratched surface of computer technology. I have succesfully built about a dozen computers for family friends and myself. I even sold a couple of them. Building a computer doesn’t require a high degree of technical skill, however it does require a little mechanical aptitude. Building may not be proper term, assembling would be more appropriate. That’s actually what you do, you assemle right components then install an operating system which is only phase of project that requires any technical ability. Building your own has several advantages, for one you can save some money. But don’tget idea that you can sell them at a profit. There’s too much competition at low end. All major manufacturers have budget models, most of which you can buy with substantial rebates and good warrantees You have a number of options, you can build from scratch or you can build from a barebones kit. I recommend latter for your first attempt. You also have choice of using all new components or using some recycled parts. If you have a reasonably up to date PC that died ther are probably a number of parts that you can re-use, and you can buy a lot of good used components from eBay and other online sources. Refurbished parts are a good option. The first thing you have to do is determine your requirements. If you’re going to just surf Internet, do e-mail and a bit of printing, go for cheapest you can buy. You will still have plenty of capacity for simple tasks. Next you have to decide whether to go with a barebones kit or do a complete build. Kits are recommended because generally that’s most economical way to go, and it’s definitely easier. Installing a mother- board can get dicey for uninitiated. There are a lot of little wires to connect that can give you greif if they aren’t in right place. Barebones kits come in many iterations. The most basic consists of a case, motherboard and power unit. Some have on board video and audio cards, others include modems and cable connections and some even sport keyboards, mice and speakers. Read specs carefully because some of thes components are expensive to buy separately.
| | What is Data Recovery? - A brief IntroductionWritten by Simon Steggles - www.disklabs.com
What is Data Recovery? Data Recovery is process of retrieval of inaccessible or corrupt data from digital media that has become damaged in some way. Data Recovery can be used to recover data from devices as varied as Hard Disk Drives, Memory Cards, Tapes, Mobile Phones, Personal Digital Assistants, Floppy Disk’s, CD’s, DVD’s, Data Cartridges, Xbox’s and many more items. Data Recovery may be needed for reasons as diverse as hardware failure, (the tape has been ‘chewed’ up, hard disk drive has failed, user has maliciously damaged computer or digital device, or it could have suffered fire or flood damage). All of these instances will require services of a professional data recovery company if data was of such value (be it sentimental or financial) that cost of services are less than perceived value of data which is no longer accessible. It is not just businesses who are at risk from Data loss. Clients requiring data recovery come from all walks of life, including large corporates, smaller businesses, and self employed to “joe public” who, with introduction and subsequent boom in use of digital cameras etc to record holidays and special occasions may have lost anything from sentimental data to critical e-mails, and personal account details. Students are often grouped under this heading too. There are numerous ways that Data can be recovered from digital media which can vary greatly, simplest method can often involve running of basic software on storage medium in question. This is always a dangerous idea, because recovery data could overwrite very data that is being recovered. More complex commercial software tools are available which will do this job more professionally. No software fix should be attempted prior to original media being imaged, enabling recovering company to work on a ‘back-up’ of original software. The most professional companies will also take a second image should there be a problem with first image that is being worked on for recovery. The next problem
