2G computers Transistors replaced vacuum tubes in the 2G computers. Transistors have become the key ingredient of all digital circuits. Including computers Today’s latest microprocessor contains tens of millions of microscopic transistors. Advantages and disadvantages of 2G computers; Advantages; 1. less expensive and smaller 2. fast in speed Disadvantages; 1. Those computers are not used as personal system 2.Preferably used for commercial purposes. 3. Maintenance of machine is still required.

Слайд 4


3G computers The development of the integrated circuit was the hallmark of the third generation computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which increased the speed and efficiency of computers. Third generation computers were interfaced with OS. This computers became accessible for audience. Advantages; 1. Smaller in size 2. Low cost 3. Multitasking 4. high reliability 5. OS Disadvantages; 1. Need complex technology 2. integrated chups are still difficult to maintain.
