Everyone knows that our world cannot exist without computers. Ever tried to make a purchase at a convenience store when their computers are down, ever waited for someone to make change when their register computer is down, or have you ever tried to find a book in a library when the system is down? If you have ever experienced one of these inconveniences, you know that our world hinges on whether or not our computers are working.
Remember when you told your teacher that the dog ate your homework? Did she believe you? Probably not. Now the excuse is my computer crashed, my printer wouldn't print, or we were out of ink. Even kids rely on computers to do their schoolwork. The days of pen and pencils are almost over. In fact most students know more about computers than their teachers or parents. They don't even remember a time without computers.
As computers become more and more intuitive and powerful, we must proceed with them. If you are still among the population that resents the encroachment of the computer, think about this scenario. If Eve in the Garden of Eden had access to the Internet, she could have looked up information about snakes. She would have found out that they have forked tongues and an evil reputation. Instead of listening to the snake's lies, she would have thrashed him with a tree branch. Think how much better our world would be now.
The best present any graduate can get this June is a desktop computer or a laptop. In my day, girls were given matching luggage to take their clothes to school. Yes, I know I am dating myself, but I do have a point. Today buy your child a computer and let them take their clothes is a paper sack. They don't care; an old gym bag will do. I know; schools have computer labs, but they are always full. Wouldn't you rather your son or particularly your daughter not be out of the dorm or apartment working on projects or papers? Also, when your newly graduated senior has moved away to school, e-mail will become your best friend. Even if you hate computers, you will learn to love them because they will become your link to your child. The nest will never be empty as long as you have e-mail.
Computers are links to the outside world. The world has never been more accessible or smaller. You have to keep up or you will be left behind and who wants to be the last straggler on the planet? Not me!

Choosing A Video Card
A video card is that device ( a loaded circuit board ) that determines the screen output or video display of the computer. It is also known as the graphics card, graphics adapter, display adapter or video adapter.
The video card is either installed directly on the mother board or in an expansion slot. The intended use determines which type to use.
What To Check For When Choosing A Video Card
1. Determine how the computer will be used. Is it for computer games or just for ordinary encoding?
There are different types of video cards for different uses.
2. RAM is resolution required to meet the video output needed.
The memory of a video card is very important for speed because it holds the common operands for the images. Since the video card can access its own memory faster than that of the mother board, the images are displayed faster.
3.Mother board and Video card format compatibility.
A mother board doesn't support all kinds of video cards. Some mother boards only have the GPUs or graphics processing units which maybe adequate for an average business or home use but not applicable where more graphics capabilities are needed. A GPU is a video card's own processing unit.
Mother boards may have the following expansion slots: AGP slots, standard PCI slots, 1xPCI EXpress slots, 16xPCI Express slots. Make sure the video card and the slot where it will be installed are compatible
The 16XPCI Express slot has compatibility with the most video cards, so it is advisable to buy this card for a new computer. The next newest slot is the AGP slot which came before 16xPCIExpress.
The least recommended slot is the PCI slot because there are only a few video cards compatible with it and most of them are the slow , expensive type.
4. TV output capability
Not all video cards have this capability. Be sure to check this out.
5. The fan on the video card must be working to prevent over heating of parts which slows down its performance.
6. Price- how much can you afford to pay?
The compatibility of components determine how the equipment functions. In the case of video cards, there is more need to check for compatibility due to the various models developed to meet various needs.
Incompatibility is expensive, for how will you install a video if it doesn't fit in the expansion slot?
