Hard Disk...!!!!!

Some ten years ago, the cost of memory was very high. Earlier computers came with a hard disk capacity of 2.1 GB. This capacity was the normal capacity, but later computers came with 4.3 GB. But this small amount memory costs several thousand rupees. But nowadays, the pen drives are coming with 16 GB memory space. This drastic difference is due to the development in technology. In the current market, hard disk of 1Tb size is available which cost few thousand rupees. With one 1Tb of memory, one can store hundreds of movies and thousands of songs and many more.
