Answer:
The Turing test is a test of a machine’s ability to exhibit intelligent behaviour equivalent to, or indistinguishable from, that of a human. The test involves a human judge engages in natural language conversations with a human and a machine designed to generate performance indistinguishable from that of a human being.

All participants are separated from one another. If the judge cannot reliably tell the machine from the human, the machine is said to have passed the test. The test does not check the ability to give the correct answer to questions; it checks how closely the answer resembles typical human answers. Turing predicted that by 2000 computer would pass the test.

2. Exploration of outer space:
Robots are very much useful in this field such as they are used to do all the tasks related to launch a satellite.

3. In intelligent homes:
Robots are used in home segments to safe guard the home, automatically open the gate, doors and windows, etc.

4. Exploration in difficult environments:
Human beings are not ready to work situations like too hot and too cold. Since it is a machine robots are used instead of human beings. Robots are used in oil filed etc.

5. Uses in military:
Unmanned air crafts and vehicles are controlled by robots. Drones and computer controlled cameras are used in Military service.

6. Uses in agriculture:
Nowadays in India, the agriculture field is also in mechanization trend. Hence increase productivity.

C. Computer vision:

D. Natural Language Processing:
It deals with how computers communicate just like a human being communicate naturally. Natural languages are languages spoken by the people. To achieve this ability to communicate like a human being is a laborious task. NLP is further be classified into two, Natural Language Understanding(NLU) and Natural Language Generation(NLG).

• NLU – The ability to understand languages like English, Malayalam, etc.
• NLG – It is deal with creation of output, i.e. generate words and giving reply.

E. Automatic Speech Recognition(ASR):
To login some computers, laptops .tabs, smartphones, etc, and to open some gates, doors, etc you have say the password orally. The computer recognizes the speech and opens the device to them.

Such devices are working based upon NLP technology and this system is called Automatic Speech Recognition(ASR) system. To implement this system the requirements, are mica or a telephone and convert the oral instruction into written text. Examples are Apple iOS, Google, etc.

F. Optical Character Recognition(OCR) and Handwritten Character Recognition Systems. (HCR):
It is used to read text from a paper as an image and translate this image into a form that computer can manipulate. For example, if we want to enter the text contents of a book by typing using a keyboard will take more time. Instead of this by using OCR and HCR we can easily do this. OCR is expensive. HCR system reads handwritten texts and converts it into computer-readable form

Geosynchronous satellite moves at the same Revolutions Per Minute(RPM) as that of the earth in the same direction. Thus both the earth and the satellite complete one revolution exactly in the same time and hence the relative position of the ground station with respect to the satellite never changes.

Geographic Information System(GIS) technology is developed from digital cartography and Computer-Aided Design(CAD) database management system. GIS as the name implies capturing, storing for future reference, checking and displaying data related to various positions on earth’s surface.

GIS can be applied in many areas such as soil mapping, agricultural mapping, forest mapping, e-Governance, etc. GIS is used in development planning like strategic rural and urban planning, infrastructure planning, precision agriculture planning, etc.
