FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Transistors transformed the world of electronics and had a huge impact on computer design. Transistors made of semiconductors replaced tubes in the construction of computers. By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space.

Detailed explanation-2: -In normal computers, bits are the smallest units of information.

Detailed explanation-3: -Recently, IBM made headlines by producing a prototype chip with transistors around 7 nanometers wide, about 1/10, 000th of the width of a human hair and half of the size of even the smallest transistors on the market today.

Detailed explanation-4: -Smaller takes up less space and requires less power, and in most cases it is faster because of the time required to propagate signals over large distances.
