One of the biggest advantages of using transistors is their small size. Even though vacuum tubes have continued to grow smaller over the years, transistors have decreased to literally microscopic proportions. The size difference between vacuum tubes and early transistors was the reason computers went ...
these devices are used in the place of vacuum tubes. The BJT is a current-controlled device where the o/p of the base terminal or emitter terminal is a function of the current in the base terminal. Fundamentally, the operation of a BJT transistor is determined by the current at the ...
and slow processing speeds. The first phase used a vast system of thousands of interconnected vacuum tubes to create a circuit. This not only took up an entire room but also required high amounts of energy and time-consuming maintenance. The second phase of computers usedtransistorsthat were no...
