25 years of an IBM computer

On August 12, IBM in the US celebrated the 25th anniversary of the world's first computer build.

Although this IBM 5150 PC is noisy, running slow, very expensive, not more powerful than a pocket PC today, it marks an important milestone in human science and technology progress.

The machine was born on August 12, 1981, a product of a year of intense research by a group of engineers working in Florida state. The machine weighs 11.4kg, with a floppy drive and keyboard weighing 2.7kg, memory only 16 kilobytes, or 50,000 times less than the current computer.

However, if you want to add color graphics, two floppy drives and a printer, you have to pay three times the amount to buy the machine.

Because IBM did not emphasize the proprietary OS of Microsoft Software Company, Bill Gates and his colleagues sold the operating system to other firms, so they grew quickly in a short time.

Since then, computers have been continuously improved, more compact, more advanced and cheaper, becoming familiar with people all over the world today.
