The Five Generations of Computers Explained with Stage by Stages
   The Five Generations of Computers Explained with Stage by Stages..............         The term ‘computer generation’ is often used in relation to the  hardware of computers. Each phase of computer development is known as a  separate generation of computers. Each phase of development is  characterised by the type of switching circuits it utilized.Most  computers today use the idea of ‘stored program computer’, proposed by  Dr. John Von Neumann in 1945.   The architecture of a computer is based on three key concepts;    i. Data and instructions are stored in a single read-write memory.    ii. The memory contents are addressable by locations.   iii. Execution takesplace in a sequential fashion, from one instruction to the next unless modified  explicity.   First Generation Computers (1949-55)   The first generation used vaccum tubes, and machine laguage was used for  giving instructions. They used the concept of ‘stored program’. They  were very large in size and their programming...
