The side effects that my digital life is having on my real life are very complicated in some ways, some people see me on a social network and get the wrong idea of me or something like that , then when they see me in person it's a problem or an attitude there. It's a very complicated thing to be involved in a social network and go to school with those people that are on the same network as you, or meeting up with new people because they'll either love everything about you on that network or hate everything about you and then when you finally meet them or see them in school their will be a lot of misunderstanding there.
No i don't find myself getting jealous nor left out when activities are going on , on facebook and im not involved. I really don't care to much for things like that in the first place so that wouldn't bother me one bit. My friends know how i are so they know that i don't get involved with an activity on a social network and i don't care to be left out.
Yes sometimes i do have trouble remembering certain material when i interrupt my studying to check my facebook because then i get tied up in that and i can't focus anymore, i become so caught up that when i go back to studying it's extremely hard for me to focus. Yes my mom and dad always worry about how much i text and be on the internet, they say if i spent that much time on my work and books i would be extremely focus & dedicated to school.

How can events be signaled?
In Scratch, blocks whose labels begin with "broadcast" signal events whereas blocks whose labels begin with "when" handle events, the latter of which, recall, effectively represent threads themselves.
Describe IN YOUR OWN WORDS how sprites use events to communicate.
Two sprites might want to play Marco Polo with each other, with one sprite's behavior defined by the leftmost thread below and the other sprite's behavior defined by the rightmost thread.
What happens when you use multiple threads? A program with multiple threads, then, can do multiple things at once.
What label begins a thread in Scratch? In Scratch, any block whose label begins with "when" essentially demarks the start of a thread; think of what Scratch calls a "script" as a thread.
Why do you think you should use separate threads?It's often helpful to use separate threads for conceptually distinct tasks.
A variable is a placeholder for some value, much like x and y are popular variables in algebra.
How are variable represented in Scratch?
In Scratch, variables are represented with blocks shaped like elongated circles, uniquely labeled by you.
What are the two types of variables and how can they be used?
Variables, generally speaking, can be local or global. In Scratch, a local variable can be used by just one sprite; a global variable can be used by all of your sprites.
What is a Boolean variable?A variable that only takes on a value of true (i.e., 1) or false (i.e., 0), incidentally, is called a Boolean variable.
What are the labels of the loops in Scratch?Any block whose label begins with "forever" or "repeat" is a looping construct.
How is a conditional statement used in a loop?Sometimes, you want execute some statement multiple times, each time varying your behavior ever so slightly. We thus turn our attention to variables.
A condition is something that must be true in order for something to happen.
What are some statements of a conditional construct?
A condition is thus said to "evaluate to true" or "evaluate to false."
What happens when you use the if construct?
With it can we instruct a sprite to say hello only if, say, the user has depressed the mouse button:
What happens when a construct is nested?With the above construct can we instruct a sprite to say hello or goodbye, depending on whether the user has depressed the mouse button:
Boolean expression is an expression that is either true or false.
What is the shape of the Scratch block that is a Boolean expression?
The shape of the Scratch Block is shaped like a elongated diamond.
When do you use Boolean expressions in programming?when constructing conditions, to which we turn our attention next.

I think modern technology reduces stress, i don't necessarily think it gives anyone stress it's more like to remove all the unnecessary stress that we have, because technology basically handles everything for us.

Some problems that "us" teenagers face as a result of social networking is not concentrating, when we're online for a project or something we get easily distracted by another site such as "Facebook. We don't know how to just concentrate on what's important at the time. We also seem to get on another site and do that and try to do our project at the same time.
Interacting all the time affects the way i think and communicate because im never really focus, it's like all i ever think about is getting on facebook, twitter or texting on my phone everything else doesnt really seem to matter to me at the time. When im in school i can't concentrate on my main focus which is work because im so caught up on facebook.
Social media affects my school work in a negative way because like i said before i can't concentrate on my school work, i get thrown off too easily by these websites.
I dont really agree with the article saying social networking affects your social manners , it doesn't affect mine at all. It might affect certain people who don't know how to control their mouth, but those who do have manners , it doesn't affect us at all. However i do think it affects our writing skills because once we're on facebook or something most of us talk in some type of slang and it when we do that we get to use to it, then we begin to use it when we're doing school work and that's messes us up a lot.

What do computer networks do? A network enables users to share files and resources, such as printers, as well as send messages electronically (e-mail) to each other.
What are the 3 types of networks?
LAN (local area network)
MAN (metropolitan area network)
WAN (wide area network)

Watson is a work-load optimized system that can answer questions posed in natural language over a nearly unlimited range of knowledge. Watson is also a computer consisting of a roomful of the company's Power7 processors. But the real genius in the system is that it can understand language well enough to figure out the wordplay that makes up a Jeopardy! question.
Its much harder for a computer to compete on jeopardy than to play chess because,a chess computer needs only to be able to do math. But a statement like "This president said he was a jelly donut," would stump most computers, who have a lot of trouble with the implied meaning of words. (The answer is "who is John F. Kennedy?"). It's not really a good thing for humans if they're really coming on jeopardy to win some money that they need. I don't think the computers would really like this help but i also don't think it would hurt people.
Computers can solve a certain amount of problems. Well from judging from the Watson it maybe a possibility that computers will take away more jobs. It's a strong possibility that computers may even take over the world later on in life, but we don't know for sure now.
