IT Trainer Questions

Dalvik serves as a virtual machine, and it is where every Android application runs. Through Dalvik, a device is able to execute multiple virtual machines efficiently through better memory management.

Economic resources include land, labour, capital and entrepreneurship. 

Entrepreneurship is also considered an economic resource because individuals are responsible for creating businesses and moving economic resources in the business environment.

These economic resources are also called as Factors of production.

For neutral atoms, the periodic trends in atomic size can be described like this

Atomic size decreases when going from left to right across a period,
Atomic size increases when going from top to bottom down a group.

Let's use these trends to try and figure out which atom would have the largest radius.

If you look at elements that are located in the same group, potassium will have a larger atomic radius when compared with sodium. Likewise, bromine will have a larger atomic radius when compared with chlorine.

Now focus on potassium and bromine. Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.

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. 

ITIL Availability Management aims to define, analyze, plan, measure and improve all aspects of the availability of IT services. It is is responsible for ensuring that all IT infrastructure, processes, tools, roles etc are appropriate for the agreed availability targets.

A project has a beginning and an end and passes through several phases of development known as life cycle phases. Every project has certain phases of development. A clear understanding of these phases allows managers and executives to maintain control of the project more efficiently.
These phases are varied depending upon the industry involved but all follow the same basic steps.

How Important is Project Life Cycle::

1. This is a tried and tested method for delivering projects on time, within budget and to the expected quality targets.

2. Aids communication and helps define roles within the project organisation as it provides a framework for the project that is visible and understood by all members of the project.

3. The project lifecycle will allow the project manager to link progress directly to each phase and recognise the completion of each phase

4. The phases within the project lifecycle provide an understanding of the evolution of the project, being able to identify areas that need greater attention at different times such as risk management in the early stages and more Project Evaluation Reviews during the Implementation stage.

5. At each stage, approval is generally required from outside the project team before proceeding to the next stage.

6. The project life cycle also allows for the gate procedure to be used.

7. At each stage, approval is generally required from outside the project team before proceeding to the next stage.

The second would employ a comma, or semi-colon, and not a colon so it is not properly punctuated.

The third sentence would not be correct because it uses 'like', usually used for comparison. Since you are not comparing two questions, it would not be appropriate.

The fourth sentence has 'is' before the colon, which is a implies declaration and not listing. So, again, it would not be appropriate.

Hence, the first sentence, however, is punctuated correctly.

A promise. 

The Promise made to somebody by you can be break but you cannot touch it.
