Thread: Thumbnails of computers

The computer is the heart and brain of ICT not is that is used in this or that field is responsible for life itself. In recent decades all devices in the computer has evolved from the miniaturization their components new technologies of information are based on microelectronics the density of transistors in the circuit is integrated twice a year leading to the emergence of nanoelectronics and This on our PCs and whose future is concerned and occupy the U.S. Japan and European countries Why is it?

Microcomputers or personal computers had its origin with the creation of microprocessors. These PC are relatively cheap why are widespread in almost all sectors of society.

In terms of processing capacity this using the technology of multiprocessors, are known models Dual-Pentium II with two processors in the same plate basic variants exist until more than 16 microprocessors in a single computer.

In the early nineties, a hard drive stores 500 MB now being sold hard drives of 160 GB. As floppy disks almost no one remembers the discs 5 and a quarter inch that stored 360 Kb which became obsolete in short time. Today there Memories flash that can store the equivalent of thousands of records of 3 and a half inches. Not to mention the CD and DVD of large capacities and speeds increased access to information.

As is known for miniaturization has been a trend characteristic of the whole development of modern industrial, which has focused features in smaller devices. This is manifested in the most evident in the case of microelectronics. Since the sixties, the transistor density on integrated circuits has been doubling each year resulting in nanoelectronics.
