2. content THE HISTORY OF COMPUTING GENERATIONS OF COMPUTERS FIRST GENERATION SECOND GENERATION THIRD GENERATION FOURTH GENERATION FIFTH GENERATION

3. The HISTORY OF COMPUTING The computer had its beginning in 19 th century when English mathematics professor named, Charles Babbage designed Analytical Engine.

4. GENERATIONS OF COMPUTERS

5. FIRST GENERATION (1940-1956) VACUUM TUBES Hardware Characteristics Software Characteristics Other Features Vacuum tubes Magnetic drums Input – Punched Cards & Paper Tape Output - Printout Machine Language Solved only one problem at a time Mostly Scientific Application Bulky in Size Highly unreliable Limited commercial Difficult to use

6. FIRST GENERATION (1940-1956) VACUUM TUBES A UNIVAC Computer A ENIAC Computer

7. second GENERATION (1956-1963) transistors Hardware Characteristics Software Characteristics Other Features Transistors Magnetic Core Memory Magnetic Tapes Disks for secondary storage Batch Processing system Assembly Language High level programming languages developed Faster, Smaller, more reliable. Easier to program than previous generation systems

8. THIRD GENERATION (1964-1971) integrated circuits Hardware Characteristics Software Characteristics Other Features IC’s with SSI and MSI technologies. Larger Magnetic Cores Memory Larger capacity disks and magnetic tapes secondary storage Timesharing operating system Standardization of high level programing languages Machine independent software Faster, Smaller, more reliable, easier and cheaper to produce. Scientific, commercial and interactive online applications. Integrated Circuit Third Generation PC

9. fourth GENERATION (1972-2010) microprocessors Hardware Characteristics Software Characteristics Other Features Microprocessors, semiconductor memory Personal Computer Super Computers based on multi processing technologies Internet GUI Based Operating Systems Multiprocessing OS Object Oriented Design and Programming Distributed OS Small, affordable, reliable and easy to use PC’s General Purpose Machine Easier to upgrade Portable computers MICROPROCESSOR FOURTH GENERATION PC

10. fifth GENERATION (present & beyond) artificial intelligence Hardware Characteristics Software Characteristics Other Features Superconductors Powerful servers, supercomputers Interspace Cluster computing Can understand natural human language Voice Recognition Capable of learning and self organization
