A brief history behind the invention of computer is as follows: It has rods to perform arithmetic calculations The device was widely used by accountants and bookkeepers Blaise Pascal: Each wheel displayed the digit 0 to 9 Only could do was add and subtract numbers Von Leibnitz: A French scientist who developed a machine which could perform addition, subtraction, multiplication and division Punched Board: Later on, the system was used computing devices Charles Babbage: He invented a analytical engine in that was automatic This engine could perform 60 additions per minute Herman Hollerith: In , Herman applied the idea of punchboards in computers He used punch cards for input and output Atanasoff: Different generation of computer is as follows: It contains millions of electronic circuits Examples are Apple Macintosh, and IBM PC Advantages More powerful and reliable than previous generations Very small size Less power consumption and less heat generated Fan for heat discharging No air conditioning is required Best speed to read instructions i.

Copying is only available for logged-in users. Binary denotes using only ones and zeros thus, lit lamps represented ones and unlit lamps represented zeros. The irony of this is that people needed to perform another mathematical function to translate binary to decimal to make it readable to the user. It was a huge, monstrous size nearly that of a standard railroad car.
It contained electronic tubes, heavy gauge wiring, angle-iron, and knife switches just to name a few of the components. It has become difficult to believe that computers have evolved into suitcase sized micro-computers of the 's.
Computers eventually evolved into less archaic looking devices near the end of the 's. Their size had been reduced to that of a small automobile and they were processing segments of information at faster rates than older models. Most computers at this time were termed "mainframes" due to the fact that many computers were linked together to perform a given function. Organizations such as these had the funds to afford such technologies.
However, operation of these computers required extensive intelligence and manpower resources. The average person could not have fathomed trying to operate and use these million dollar processors. The United States was attributed the title of pioneering the computer.
It was not until the early 's that nations such as Japan and the United Kingdom started utilizing technology of their own for the development of the computer. This resulted in newer components and smaller sized computers. The use and operation of computers had developed into a form that people of average intelligence could handle and manipulate without to much ado.
When the economies of other nations started to compete with the United States, the computer industry expanded at a great rate. Prices dropped dramatically and computers became more affordable to the average household. Like the invention of the wheel, the computer is here to stay.

Many people say that the predecessor to the computer was the typewriter. The typewriter definitely required training and experience in order to operate it at a usable and efficient level. Children are being taught basic computer skills in the classroom in order to prepare them for the future evolution of the computer age. The history of computers started out about years ago, at the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around, according to programming rules memorized by the user, all regular arithmetic problems can be done.
Another important invention around the same time was the Astrolabe, used for navigation. Blaise Pascal is usually credited for building the first digital computer in It added numbers entered with dials and was made to help his father, a tax collector. In , Gottfried Wilhelm von Leibniz invented a computer that was built in It could add, and, after changing some things around, multiply.
Leibnitz invented a special stopped gear mechanism for introducing the addend digits, and this is still being used. The prototypes made by Pascal and Leibnitz were not used in many places, and considered weird until a little more than a century later, when Thomas of Colmar A. Charles Xavier Thomas created the first successful mechanical calculator that could add, subtract, multiply, and divide. A lot of improved desktop calculators by many inventors followed, so that by about , the range of improvements included: Accumulation of partial results, storage and automatic reentry of past results A memory function , and printing of the results.
Each of these required manual installation. These improvements were mainly made for commercial users, and not for the needs of science. It was the first color portable computer. It was based on the MOS and it also had fast color graphics. The Commodore was a cheap computer for the features it had and people all around the world bought it.
Later in , Apple came out with a new computer called the Macintosh. It had Kb of RAM, it also had a 3. It was a bit processor and it also contained 60, transistors and had 16 registers. It came with a lot more ram or Kb and new floppy disks drives which could hold up to 1. It was first color computer by Macintosh. The color was 8 bit deep and it was also available in bit. The screen resolution went up to x and it had RAM of 64 Mb. It had a Motorola processor with FPU.
The Macintosh II was not a popular computer, customers complained about the price being too high. The NeXT had some faults to it. So it was so expensive for the consumers to by it and the use of wrong type of language.
In , Intel Pentium Processor began developing and went through the industry faster than any of the previous processors by Intel. In , Apple introduced a new computer known as the Power Macintosh. On August 24 , Microsoft came out with Windows Which became very popular and it was affordable for many of the families.
It had full networking support; it included tolls for accessing the Internet. The operating system was bit, which helped in improving the performance of the computer. Windows 95 were being advertised everywhere. They were being advertised on TV, radio, newspaper, magazines, billboards and many other places. The PC industry became very popular when Windows 95 was releases because it was affordable and easy to use.
The hard drive space also went up a lot to GB.
