First Generation: -
The first generation computer used vacuum tubes for circuitry and magnetic drum for memory. Their size was huge and big, and generates lot of heat. These computers were very expensive to operate and in addition to using a great deal of electricity. The UNIVAC and ENIAC computers are
examples of first-generation computing devices. They relied on machine language. Any instruction in this language is given in the form of string of 1s and 0s. Where the symbol 1 stand for the presence of electrical pulse(or True) and 0 stands for the absence of electric pulse(or False).

Second Generation: -
These computers used transistors. Transistors allow computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Second generation computers used Assembly language or Symbolic Programming Languages.
