1. Really provides better cooling for your computer hardware
We all know that heat can really kill the motherboard, processor and other chips that are found in a computer case. If the temperature is too much it can fry the chips and leave your computer worthless. The more work you do, the longer you do it, the higher the workload on the pc. This causes heat to build up inside your computer. The traditional cooling fan that you can find on the back of the power supply of your computer is normally not enough to get it all the cooling it needs. Even with the other fan attached to the processor chip, your computer will most of the time not get all the cooling it needs.
If you were to use a rack, this would help to give your computer the cooling it needs, since it gives you a lot more space, unlike computers that don’t have racks.
2. You’ll have better air circulation
Without adequate space for your computer, there won't be good air circulation and this can damage many things in your computer. A rack mount computer therefore gets better air circulation than one without it. And this goes a long way in protecting your computer.
3. Prevents vibration when playing load music
Good computer racks out there have vibration-dampening tendencies to prevent the vibration of your computer- especially when listening to load music from your speakers. Without these vibration-dampening tendencies, your speakers and even compute can slowly slip off your desktop, thereby causing damage.
4. Give more space for your computer
Your rack mount computer has more space than others without one. You are able to do more work than if you didn't have a rack for your computer.
If you take all the above advantages into consideration you will come to find that using a rack mount computer instead of one without a rack is the way to go.

Building A PC
Many people simply go to the retail store and get sold to when it comes to computing equipment. You would be very surprised how easily you can pick up all the core components and assemble yourself or get a friend or family member in the know to do it for you. All the top brand PC manufacturers such as IBM, HP and Fujitsu Siemens offer you pre built PC’s, Dell on the other hand will take your order and build to your own style. Off them all Dell will come across more flexible with the specification, however, building your own will not only save you many dollars but make you aware of just how much profit these guys are making.
What are the core components of a PC?
Well let’s start with the basics you will need no matter how high or low spec you want the computer:
PC Case – Motherboard – Processor Chip – Fan – Power Supply – Hard Disk Drive – Memory (RAM) – Power Cord – Keyboard & Mouse – Graphics Card (may come on the motherboard) – Sound Card (if you require one). All these components will get you started. Remember build the PC to your own needs. Gaming PC’s generally need a good graphics card with 3d capabilities while general office PC’s do not need such powerful cards.
Processors:
Intel and AMD are the key players when it comes to processors, Intel offer the Pentium chip or Celeron while AMD have their range such as the AMD Athlon and Sempron. While both companies have their benefits Intel’s being that they are the largest selling globally but AMD seem to have the faster processing capabilities. When looking at the processors think sensibly and ask yourself do you really need the latest and greatest or would you notice the difference in point two of a processor e.g. 3GHz compared to 2.8GHz.
Remember keep the cost down, basic components such as the PC case comes in a number of different styles such as Mini Tower, Desktop. Choose what suits you. RAM (memory) will depend on what you plan to do, some games and simulators require large amounts of memory so check before you buy, and the graphics card will also depend on your PC plans. If you are generally using the PC for home and Internet browsing remember to purchase a modem or if you are planning broadband arrange with the installer and get yourself on the waiting list.
Building the PC
Building a PC is not as daunting as it seems. If you have not attempted to do this before it is a good idea to have supervision. Some of the components such as the memory need careful handling due to static electricity. Get an anti static wrist strap to protect the components, they cost very little and could save you a lot of money. There are plenty of cheap books out there to guide you in assembly but you will also find free articles online with diagrams for assembly.
Software:
Hardware is one thing but you also need the software such as the operating system and anti virus software for protection against viruses. Depending on what you want and what you are used to using before you can get free operating system such as Linux. Most of us are used to Microsoft Windows but you will require a licence to use this software. You may also need some office software such as Microsoft Office XP or 2003 standard or Professional edition. The anti virus software is essential and Norton’s or McAfee are some of the better known brands. There are also free downloads that will help protect your PC such as Stinger and Ad-Ware.
In Brief:
Building your very own PC gives you the flexibility that most manufacturers do not. The price is greatly reduced if you can assemble yourself and it will give you a great insight to all the components and key terms in computing. You will be surprised to find that not all is as technical as first seems.
Some quick notes: Do not forget the following: Modem – Make sure you also have enough USB ports for external devices such as a printer or digital camera. Always back your files up such externally on the off chance you have a problem with the Hard Disk Drive and your files are not transferable, something like a usb keyring would be ideal.

Repairing a Damaged CD
Why compact discs get damaged. Compact discs are all plastic. Compact discs are even not sensitive to magnetic fields as in case floppy disks, which never used to retain data when even a slight magnetic field is crossed with floppies. Then what is the reason why CDs get corrupted?
CDs work on the principle of reflection of light. CD drives have a built in laser that is used to read data. When laser is focused on to the CD the beam get reflected to a point when there is some data on that are i.e. 0 or 1 the points where light beam lands back is different which symbolizes the bit value.
When something on the CD breaks the path of the laser light, something like dust particle or something else like a FINGER PRINT!!! Finger prints are nothing but natural oil from skin that sticks to the surface in contact with the skin in a pattern of skin cells. This oil or say fingerprint helps in refraction of light and loss of data to the reading source i.e. laser.
When CDs don't run the reason is because something is interrupting the laser to read the shinny side of the CD. But I have important data what should I do now?
Most of the times it is because of dust or fingerprints, you need to clean the CD.
You can clean your CDs with plain water or a bit soapy water. And it is better to clean the CDs after some time. But this doesn't mean you should start putting your CDs in dishwasher or washing machine every week.
All you need to do is to wipe the shinny side of the CD with a clean moist cloth and try running it again make sure the CD is dry before you run it.
People say about using all different sorts of things to clean CDs like toothpastes, wax polish etc but I would recommend you to buy some CD cleaning kit. But if you still want to go trying, do let me know the results.
And one thing I must add is that DVD work on the same principle and are bit more sensitive to dust and fingerprints. You can also use the above mentioned procedure for DVDs. But you still need to be careful with DVDs.

A Close Look at DVI Cables
We all have many times heard about DVI, but what does it really means and what it does? What is the main function of this tiny white port on a video card? How it can benefit you and your personal computer? Do you know which DVI is suitable to meet your requirements?
Digital Video Interface is created by Digital Display Working Group to solve the problem of accommodation analog and digital interfaces just by using single connector. It was developed because of insufficiency of standardization in digital interfacing.
Three types of standards can be seen in DVI cables. It is very important to know how each type looks like before buying to upgrade your DVI. So it is very important to know how DVI cable works and which one will be most beneficial for you.
However, DVI cables are still in the phase of development. Hence there is no specific standard for the DVI cable. In ideal circumstances, DVI home theater cable is capable to create ' digital to digital' connection between the data or video sources and home theater projectors.
The standard rule for DVI cables is that it should have maximum length of 5 m for trouble free operation. It is very typical to decide a DVI cable first time.
There are two types of DVI connector and each has its own characteristics. The flat pin denotes whether the cable is analog or digital. A flat pin with four surrounding pins denotes either DVI-A or DVI-1. A single flat pin denotes DVI-D. The pin sets depends upon whether the cable is single link or dual link or analog.
To choose a perfect Digital video interface cable you should remember these tips:
1. Check both female DVI plugs to make sure what type of signals they compatible with.
2. One or both connections should be DVI-D if you are choosing a DVI-D cable.
3. One or both connections should be DVI-A if you are choosing a DVI-a cable.
4. If one of the connections is DVI and other is VGA, and if the DVI is analog compatible, then you must buy a DVI/VGA adaptor or a DVI to VGA cable.
5. when both connections are DVI-1, you are advised to use any of DVI cable, but better if you use DVI-1 cable.
6. If one connection is digital and the other is analog then there is no possibility of connection between them.
