For most people, computer components and the innards of a computer are something that rarely needs to be considered to up close. Everyone knows it has something to do with IBM and Bill Gates, but that’s about it. But the fact is, today’s computers parts are the result of massive technological innovations in microprocessors, semiconductors and programming. Here’s a brief guide for what makes up a computer.

Most of the circuitry and the brains of a computer are today built-into motherboards and processors. The rest of it is just so that these two can function properly and interface with the user. The ‘rest’ in this case includes keywords, monitors, the mouse, etc.

The biggest processor makers are Intel and AMD, and the choice is usually whatever happens to be the latest in the market. Choices for the motherboard and chipset are a lot more varied and depend on usage, budget, location, etc. It’s best to look it up on computer hardware review and benchmarking sites before buying anything.

The other major computer parts worth mentioning include the SMPS or power supply, hard disk drive (hdd), memory (RAM) and video cards (better known as a display or graphics card). Sound cards are these days built into the motherboard, and so are modems and LAN cards required to connect to the internet or join a network. But some people might still consider getting more powerful external cards and devices for these functions.

The power supply is worth mentioning because unlike other electronic gadgets, a computer’s power supply is a very important and delicate part. It provides power separately to the motherboard and each motorized part (hdd, cd/dvd-rom, cooling fans, led displays). Each of these power cables is critical to the operation of the computer, and needs a strong and stable power supply.

Also to be noted that laptop computers and desktop computers have various needs, as far as the department are concerned. In a laptop, most of the parts are factory built, and there’s not much room for customization by adding cards or a bigger monitor, etc. On the other hand, a desktop computer can be ripped apart, upgraded and customized with better video cards, faster LAN cards, a bigger hdd, more RAM and anything else that’s necessary.

As far as operating systems are concerned, Microsoft Windows is still the world’s most dominant OS. An OS, by the way, is what interfaces between all the hardware on one side, with all the software and the user on the other side. Alternative OS options include Unix, Linux, FreeBSD and various other Unix derivatives and clones.

Commonly used software selection for web browsers include Internet Explorer, Firefox and Chrome. Office software choices include MS-Office and OpenOffice. The rest is pretty much dependent on what the computer is to be used for.

In summary, the computer parts and software required basically depend on budget considerations and usage. For instance, a person who needs to run advanced multimedia software like Photoshop or play online video games might need a powerful desktop computer with add-on video cards, a larger screen and more cooling fans. Someone who simply wants to browse the web might find a factory built configurations for a laptop quite sufficient.

When it comes to the recovery of data from a hard disk, the best option for any firm is to use the Raid data recovery method. It is a very complex process that tries to repair the damage done by the client before sending the hard disk to the data recovery firm. It is never advisable for a user to try and recover the data himself. These clients may use certain system utilities tools in order to repair the array, but they may very often cause even more trouble. And, as when things go bad, they usually do when the data is critical, these hard disks should be directly taken to a firm that is specialized in data recovery.

Therefore, the best action you can take in the situation of a Raid data recovery problem is to immediately send the hard disk to a specialized firm. Should a serious system failure occur, the whole pressure is transferred to the hard disk data recovery professionals. As the users are in the habit of starting troubleshooting processes in order to solve the problem, the data recovery experts must also repair the damage done by these processes, as they can make the data impossible to recover. The information involved in such a situation can cost many hundreds of thousands, possibly millions of dollars in labor and resources to create. This is the reason why the executives are not at all interested in finding out the cause of the failure, they just care about the fact that the server has crashed and that the problem must be immediately solved.

The procedures that Raid data recovery consists of start by making sure all of the drives are properly functioning. This may mean taking the physically damaged drives into the clean room and try to make all the necessary repairs, in order for them to normally function again. The hard disk data recovery technician then initiates a very low-level process that allows him to work around bad sectors of the disk. It is in fact making complete sector-by-sector clones of every drive. The original source drive is being put in a “write protect” mode, in order to protect the existing data during the cloning process. The actual recovery process is performed on these cloned copies!
