Questions

a.) Testing and Debugging 

Testing is process of verifying if the application matches requirements and reporting bugs; Testing is usually done by an independent testing team while debugging is a process of finding and fixing bugs with the intention of reducing bugs; Debugging is usually done by the programmer.

b.) Two tier and Three tier architecture

In a two tier architecture there is a data server and a client application. Client application directly accesses the server data. In a three tier architecture there is a data server, a client application and a server application. Client application calls the server application which in turn fetches data from the data server and returns back to client application.

c.) Alpha testing and Beta testing

Alpha testing is conducting acceptance testing in the environment where the application was developed. It is done by the customer. Beta testing is conducting acceptance testing is the customer environment. It is done by the group of customers or users who will actually be using it.

d.) Static testing and dynamic testing

Static testing is checking the application without actually running the application whereas dynamic testing checks the application by running it.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance.

The given statement "All bones stop growing by the end of adolescence" is a FALSE statement.

The principle of dominance states that some alleles are dominant, while others are recessive.

District cooling system is a well known and energy efficient technology adopted across the world. India's 1st district cooling system will come up in the green city Amaravathi, the capital city of Andhra Pradesh state.

District cooling system (DCS) distributes thermal energy in the form of chilled water from a central source to multiple buildings through a network of underground pipes for use in space cooling. The cooling or heat rejection is usually provided from a central cooling plant, thus eliminating the need for separate systems in individual buildings.
