There are a lot of people who don't agree when the first computer was built; in fact many say that the first actual conception of the idea of a computer was by J. H. Smith in 1782. He however never built the computer. His concept was called a difference engine.
Difference engines were put on the backburner until 1822, when Charles Babbage picked up the concept. He created a machine that used a decimal number system, and was powered by the cranking of a handle. Babbage was financed in his research by the British government, but they later would cut that support off.
This did not stop Babbage though, he went on to design a more analytical machine, but later on he made it more improved and put out a difference engine #2, all this happened between 1834 and 1869. Babbage made leaps and bounds in his designs.
Still other people will argue that Babbage's machine was the first electronic computer. While an earlier concept was made called the Antikythera machine, which was a mechanic device that was used to calculate the position of astrological signs.
This "earliest computer" was discovered on a shipwreck in the Mediterranean Sea, and it dates back to 250 BC. It's not known who designed this early device but it has been guessed to be designed by Archimedes, because it is similar to some of his other mechanical devices.
However, there are still other people who will argue that the abacus was truly the first computer. These were invented in China somewhere between 2600 BC and 300 BC. These abacus were used by clerks and merchants in China, they are felt to be the first computer by many people.
Alan Turing who was from Cambridge UK, he was drafted to the Bletchley park secret base where the work was being done on the WW3 enigma codes that the Germans were using. It was kept top secret until recently the name of this computer was Colossus; it was smashed into pieces at the end of the war.
The first known "modern computer" was invented during WWII, done by a German engineer named Konrad Zuse in 1941. This computer was named the Z3. It was an analog computer that was designed to stimulate the guidance system for rockets.
With some research it was found that Babbage did not build a complete machine. Thus it would be Zuse who invented the first electronic computer.
Thus to truly answer who invented the computer it's not really simple. Really you have to say who all contributed to the make up of the computer. So many different people in history helped with these inventions, by their failures and successes.
So over all the first electronic computer was invented by John Vincent Ansoff. It was named the ABC, which stood for Anatasoff Berry Computer.
A lot of people would feel that IBM was the first in designing the PC, but really prior to them was the MITS Altair 8800, Apple II, TRS80, the Atari 800, and of course the Commodore 64. Still others say Altair was not first, but instead it was the Simon by Berkley Enterprises.
So as you can see who invented the first computer is really up for grabs, and will be forever. But let's thank all these people who came up with an incredible machine that is hard to live our lives without.

Computer Devices
By eHow Computers Editor
This article will walk you through how to use plug and play devices on your computer. Plug and play devices are as simple as a mouse or a keyboard, and can be as complex as a camcorder. The Plug and Play devices are great for easy set up and ease of use due to the quick set up and use with Universal Serial Bus ports.
How To Use Plug And Play Devices On Your Computer:
Step 1
To begin, plug in the Universal Serial Bus cable that came with your plug and play device, with your computer turned off.. On older models of computers, the Universal Serial Bus jacks also known as USB, will be in the rear of your Tower unit. USB ports look like a rectangle turned on its side. There will be a small white or sometimes metal colored bracket inside the USB port, so your cable will only fit in one way. On newer models, many come equipped with at least one on the front of your unit. Locate and plug in the USB cable into the USB port on your computer tower. Now you may turn on your computer.
Step 2
Once your computer has booted up, a small box will appear saying a new device has been detected on your computer. If you wish to use it at this time, it must be set up. Click on the box, and this will begin your Wise Installation Wizard. The window will generate stating that you are about to scan your system for new devices. Click on next in the bottom right area of the window to proceed.
Step 3
Once the system has generated all of the new devices that your system recognizes, you will be given a list to look at in this window. You will need to click on the box next to the device you wish for the system to use. If you are trying to use a new keyboard, click on keyboard. You will need to look for the brand name of your device in case there is more than one installed on your system. Now that you have chosen the plug and play device to use, click next in the bottom of your window to move on.
Step 4
The window will now ask if you would like to get updates for your new device. It is recommended that you always get updates for any new device, which will include drivers that are needed for it to work properly on your Operating System. You are given the choice of looking on the Internet for them, or using a disk that came with your device. It is suggested to use the disk that accompanied your device to get specific drivers. If you are using the disk, now is the time to place it in your disk drive and click next. Once you choose which option to use, click on next at the bottom of the window.
Step 5
The newly generated window will locate all the drivers needed from your disk at this time. If you chose to look on the Internet, your Internet Explorer would launch now and do the same, locate your drivers from the manufacturers website and begin the transfer for you. Now that your drivers are updated and installed, a new window will pop up for you. This is to tell you that your new device is ready to use. You may now click Close or Finish, depending on your Operating System. Some systems will require you to Restart for the changes to take effect. If this is the case, a window will pop up to alert you to this. Just hit Restart Now, and when your restart is complete you are finished. You have just used your Plug and Play device on your computer.
