They will be capable of reasoning, learning, making inferences and behaving in ways usually considered exclusive of humans. These computers will be equipped with massive primary storage capabilities and extremely east processing speeds. Software will proliferate and get much bigger. Hardware will continue to shrink in size but internal memory will increase dramatically. "TALKING MACHINES" will be common place. Voice recognition, the ability for a machine to understand and obey spoken words will be developed. Industrial and personal robots will roll and walk. Expert systems software will place the knowledge of experts and consultants at the disposal of general users. Huge number of computers will be linked in parallel offering computing power of an inconceivable magnitude. Artificial intelligence will be used extensively to enhance the system behavior in the future.

Computer Fourth Generation

1) Computer Fifth Genaration 

2) Computer Third Genaration

3) Computer Second Genaration 


4) Computer First Genaration

The fourth generation computers possess still greater input/output, storage, and processing capabilities. In the fourth generation computers, semiconductor storage processing capabilities. In the fourth generation computers, semiconductor storage devices were introduced. In the early 1970s IBM introduced the concept of virtual storage into their 5000 and 370 series of computers.



Machines previously limited to a maximum internal storage capability of approximately one million characters now possessed a virtual storage capability in billions and trillions of characters. With this capability a machine could execute a program many times the size of the machines actual memory. Microcomputers using microprocessors as the CPU proliferated in the fourth generation.

Now a days, the compact disk (CD) promises to become the data storage medium of choice. A compact disk read only memory (CD-ROM) is encoded with on and off bits. Bits are stored on the disks (3.5 inch diameter inch diameter) aluminum surface as tiny sits at varying depths. The average CD can store about 4,800 million bits or 600 million characters of data. This is approximately a quarter of a million pages of text.




The most impressive advancement has occurred in software. As a result of these changes, access to substantial computer power, previously only affordable by very large business concerns, is now economically feasible for small business and personal applications. Personal computers are examples of fourth generation microcomputers.

These computers were characterized by integrated circuits with components so small that in many cases they were hardly visible to the naked eye. Third generation computers were characterized by increased input/output, storage, and processing capabilities. Input/output devices could communicate with computers over distances via ordinary telephone lines or could scan a page and input the information directly into the computer, could display pictures on a television-like screen, could make musical sounds, and could even accept voice input.



Storage capabilities were increased and millions of characters could be stored and randomly accessed in fractions of a second. Third-generation computers could process instructions in nanoseconds. In addition, computers were able to process several programs or sets of instructions simultaneously. Programmers were able to make use of high-level problem oriented and procedure oriented languages that closely resembles the commonly used form of expressions. Examples of third generation computers are IBM 360, IBM 370, PDP-8, PDP-11, GE 600 etc.
