Contribution of Computers towards our Society and its Future Tends

Q3. What is the contribution of computers towards out society? What are the advantages and disadvantages of computer data processing over manual data processing? Can you anticipate future trends in computer data processing? What are they?

Ans. Computers have made great inroads in our everyday life and thinking. They are put to use for all sorts of applications ranging from complex calculations in the field or frontline research, engineering simulations down to teaching, printing books and recreational games. The ease with which computers can process data, store and retrieve it painlessly have made them inevitable in office and business environments. The areas of applications of computers are confined only by limitations on human creativity and imagination. In fact, any task that can be carried out systematically can be performed by a computer. Therefore, it is essential for every educated person today to know about a computer, its strengths, its weaknesses and its internal structure.

A computer is an electronic device that can perform a variety of operations in accordance with a set of instructions called program.

Following are the advantages of computer data processing over manual data processing:

  1. Speed

Computers are much faster as compared to human beings. A computer can perform task in minute that may take days if performed manually. A modern computer can execute millions of instructions in one second.

  1. High Storage Capacity

Computers can store a large amount of information in very small space. A CDROM of 4.7 inch diameter can store all the 33 volumes of Encyclopedia Britannica and will still have room to store more information. Bubble memories can store 6,250,000 bits per square centimeter of space.

  1. Accuracy

Computers can perform all the calculations and comparisons accurately provided the hardware does not malfunction.

  1. Reliability

Computers are immune to tiredness and boredom or fatigue. Thus they are more reliable than human beings.

  1. Versatility

Computer can perform repetitive jobs efficiently. They can solve labor problem or do hazardous jobs in hostile environment. They even can work in the areas where human brain can err for instance observing motion of very fast moving articles. Also they can work with different types of data and information like graphics, audio, visual, characters etc.

 

Following are the disadvantages of computer data processing over manual data processing:

  1. Lack of Decision Making Power

Computers cannot decide on their own. They do not possess this power which is a great asset of human beings.

  1. IQ Zero

Computers are dumb machines with zero IQ. They need to be told each and every step, however minute it may be.

These limitations of computers are characteristics of human beings. Thus, computers and human beings work in collaboration to make a perfect pair.

 

Future Trends in Computer Data Processing

Computing devices based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and supercomputers is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of future computers is to develop devices that respond to natural language input and are capable of learning and self-organization.

The most noticeable characteristics of these computers will be the ability to apply previously gained knowledge, draw conclusions and then execute a task. The computer will, in short, simulate the human ability to reason.

Computers will have to be able to classify information, search large databases rapidly, plan, apply the rules which humans regard as clear thinking, make decision and learn from their mistakes. Input devices for future computers could also include speech and visual recognition.
