Communication and the internet part 2

1.   Why is communication so important during an emergency?

Communication is so important during an emergency because if you were lost or stuck somewhere and you had a communicational device with you (such as e.g. mobile, walky talky, radio and etc.) you’ll be very lucky to have one so you can communicate to one another for help.

2.   What forms of communication have been used during the recent disaster you have chosen to discuss?

Many different techniques of communication were used during Hurricane Katrina, Sandy and tohoku. Ham operators were one of the ways that helped to communicate in hurricane Katrina using voice, computers, televisions and Morse codes. Some hams bounce their signals off the upper regions of the atmosphere, so they can talk with hams on the other side of the world; others use satellites. Many use short-range, handheld radios that fit in their pockets. Cellphones were a vital aid in communicating to get help. Families were able to text or call friends or other relatives in different parts of the world to get help. If they were to try to call 911 the system would probably be overloaded. There are still many other sorts of communication used in now day’s natural disasters.

3.   What essential information needs to be communicated during a disaster or emergency?

The essential information needs to be communicated during an emergency or a disaster is where are you and your location, how many people are with you, and the most wanted one is HELP ME!!!

Communication and Internet

What communication forms are synchronous?

Chatting, instant messenger, phone and many others are all synchronous communication forms. That is because data is transfered through a method in which data is sent (upstream) and received (downstream).  The data flows at the same speed, and is spaced by timing signals.Chatting, instant messenger, phone and many others are all synchronous communication forms. That is because data is transfered through a method in which data is sent (upstream) and received (downstream).  

Which ones are asynchronous?

Text messaging is is a form of asynchronous communication. E-mail is another form of asynchronous communication. That is because  data transfer method are signals sent and received in spurts and not in a continuous stream like synchronous forms of communication.

What is needed in hardware and software for each?

A web browser ( such as internet, safari, fire fox ) is a software that is needed for asynchronous communication.   A monitor, mouse, key board, and zip drive are the hardwares that is needed for asynchronous communication.

What type of information would be conveyed by each form?

Both types of information conveyed by asynchronous and synchronous are practically the same. Information such as the location and the affected population and areas would be the information conveyed.

Tech Fair evaluation

1.We made it through to the tech fair.

2.Yes, i would change my course and turn it into an arena. 

3. It is fun to play with.

My Reflection on GM Foods

Its difficult to decide weather GM foods are good or bad.

The bad things about GM foods are that you are manipulating with the natural environment. That can cause damages in the food chain and also threaten animals and plants. Also you can't be sure of the long term effects on life. For instance some people say that you can get cancer or become infertile by eating GM foods.

The good things are that the food can last for longer and also is much more resistant to weather/climate or bugs. All this makes food production much more cost efficient and maybe people in the world won't have to starve to death.

Over all, in my opinion, you have to be very careful when messing with nature. I believe there must be other ways to feed the poor around the world and also natural food tastes much better.

My planning of GM foods Power Point presentation

MYP Unit 1: Genetically Modified Foods Worksheet 2

a) What is the science behind genetically modified foods?

-The ability to transfer genes from organisms to other organisms 

-The ability to modify DNA and genes

-Inserting more calcium, protiens, etc... into your food

b) What foods are affected by this technology?

-Alfalfa

-Apple

-Cherry tomato

-Strawberry

-Banana

-Potato

And many more

c) What are the problems with this technology?

-GM foods can harm the environment and living things
-It kills some insects including butterflies and insect larvae
-The chemicals used to genetically modify food is known to cause lots of common allergens 
-It  also gives out many unknown effects on human health

d) What action has been taken to try and prevent the technology developing?  

-So far FDA (Food and drug Administration, USA) they have sent a message to all schools. The Ministry of Health and Ministry of education in dubai, has stopped public arab schools to sell  junk foods. 

e) what how can you find out information about these questions?
