• They were big and consumed a lot of power while producing a lot of heat.
• Their reliability was limited and the data processing time was very slow (in milliseconds).

Second Generation:

• Transistors were introduced to replace vacuum tubes.
• They were smaller in size, energy-efficient, and more reliable.
• They reached a higher speed and the data processing time was reduced to microseconds.
