Ibm-pc meaning

A PC made by IBM. In 1981, the first IBM PC was introduced with a colossal 16KB of RAM. However, the company was not that optimistic, projecting that 250,000 IBM PCs would sell in the first five years. In fact, three million were sold in that period, and the PC industry, first DOS and later Windows, would become the world's largest computer base.Good Bye IBM PCIn 2004, IBM exited the desktop and laptop arena when it sold its personal computer division to Lenovo, a major Chinese PC manufacturer. IBM retained its x86-based server market with its System x series until 2014, when Lenovo also acquired the line.
