Second generation computers were manufactured using transistors instead of vacuum tubes like first generation computers. They were faster, smaller in size, more reliable, and consumed less power than previous computers. Storage technology and programming languages also improved. Their usage increased in scientific computation, business, and industry. While they provided improvements over first generation computers, newer computers provided even greater capabilities like higher processing speeds, larger storage capacities, smaller sizes through integrated circuit technology, and advanced operating systems and applications.
