simulators

** Simulators ** By: Raya Bitar 

__**Simulation: **__  Simulation is the process of designing a model of a real or imagined system and conducting experiments with that model.

__**Advantages: **__  - Able to test or experiment without harming the person or environment. - Can reach risky areas without it being dangerous - it can help a business or organization make decisions without a "huge" risk.

**__Disadvantages:__ **  - It can be expensive when buying the model - Processing power is needed to create complex models - sometimes is not accurate

Simulation was more of role-playing based activities. Games to do with the simulation would be SimCity, SimLife or The Sims.

The sims is a video game where people can build homes and create families.

The sims are models which act like normal people acting out there normal daily life, going to work, eating, running ECT.. ||

**__Digital Experimentation__ **

Digital experimentation is experimenting on a computer without ever physically touching the test subject. An example would be Photoshop, let’s say you want to dye your hair red you would experiment it first on the computer to see how it would look like.

The photos on the left are two pictures of the same girl however with a completely different hair color and different color highlights, on the bottom is a video tutorial of how to use photoshop. ||

__**__Environmental:__
 * __ Demographic and Environmental simulation:

 An urban simulator is a tool used by architectures to plan and design a city. They can design houses, roads, shops and much more.
 * An environmental simulator is a tool used by engineers to study and research the environment. They do this by using models and simulations of a certain area, professionals are able to study the area and predict how it is to look like in the future. These professionals are also able to study the effects of natural and human influences and be aware of what actions would taken to preserve it. **

Below is are three pictures of the same area however with trees added to it, this is an example of how the engineers test whether or not these plants will have an affect to the area or not.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">__Demographic:__ This refers to certain population characteristics such as age, gender, location and employment status. It is useful for the government of a country, coming up with marketing strategies and for economic research.

 * __-Security__**: Issues involved in military situations

Network traffic simulation is a process used in telecommunications engineering to measure the efficiency of a communications network. Telecommunications systems are complex real-world systems, containing many different components, which interact.
 * __Traffic Simulator__ **

<span style="font-family: Arial,Helvetica,sans-serif;">**Speed limit, Traffic control**
 * media type="youtube" key="1teqmryMngM" height="385" width="480" || This is a video showing how traffic simulators work, this is how engineers are able to know where the specific problems are in the traffic and how to resolve it. ||
 * __They measure:__**

-It is possible to test new traffic rules without putting any human in danger. __Disadvantages:__ ** <span style="font-family: Arial,Helvetica,sans-serif;">-Expensive, and data can be inputted incorrectly.
 * __Advantages:__ **<span style="font-family: Arial,Helvetica,sans-serif;">
 * <span style="font-family: Arial,Helvetica,sans-serif;">

__Social and Ethical issues:__ // **__**-Reliability**__**__:__ Data may be unreliable if it is entered incorrectly or if it becomes outdated. The machines may break down or a hacker may violate the whole design by changing the data needed for the simulation. **

__**-Integrity**__: Again, a hacker may break into the system and change the data or the data could be accidentally change
