Job Shadow Report

Where did I go for my job shadowing? ARA, Applied Research Associates is a defense contractor employed by the Department of Defense and develops software for our government. When we arrived i needed to get a badge to show i was allowed to do the job shadow. The company has classified and top secret info so I am not allowed in certain areas, they have to watch out for spies and other governments trying to get their technology! The building was a simple office and each worker had their own room. I went to meet different people within the company, the first was the graphics designer. He is working on a computer modeling system meant to help design structures for the Department of Defense.  The designer showed me different models that they use for the program. Another thing is video editing software, it is used to put together videos and change them around. He showed me a video he put together showing US soldiers training underground as well as some of their tech used in the field. The next person i met was their security administrator and trainer, she is in charge of who gets access to the secure room and insures everyone is safe. She also has a system where if you get a suspicious email you can send it to her and she will find out what it contains and who sent it. Each employee I meet had a interesting story or job and I enjoyed my time there!

Communicating on the internet

Email Clients and Servers

       To send an email, you are using an email client, the email client helps you read, receive and sent emails or download things. The email client is the tool you are using, even if you don't know it, email clients communicate with email servers to get the data where it belongs. Sometimes you give the client data so it goes to the right place with little effort on the part of the user. The email servers take the email and all attached data and pass it around so that it reaches its destination in a timely manner. The email clients are designed to be easy to use, that way a user can  use all the features on the client.  

How Email is delivered

once an email is sent the message is connected to a Simple Mail Transfer Protocol, aka SMTP, this is a set of rules on how computers communicate with emails. Then the email client will tell the server all the information it needs to send the email. Next the SMTP will will use the domain to find the address and ultimately to send the email. Once that is done the SMTP will pass the message to the incoming mail server. This server is either a POP3 server, this makes you download it, or a IMAP, the email will stay on the server, now it is in the digital hands of the recipient. The email could also be handled by internet servers when using and online email client. This proves there are many possible ways to send and receive and email online.

Instant Messaging 

This form of communication has been around since the 1990s and is an easy way to communicate over long distances. To begin a user must download the correct software for your IM service. Once you are logged in, the client software sends the server your IP address so it can connect to other users. Then anybody on your contacts list can be connected through the server, this then allows you to communicate. Mot online IM service providers are free of charge and can be found and used easily. The IM servers help connect people via their IP addresses and let the computers do the messaging!  

VOIP

• Analog signals: Curvy wave(Sine wave), used by standard phones/land line
• Digital Signals: Square wave, on or off, binary 1,0
• VoIP calls use digital signals and the internet, turns into binary.
• Voice over internet protocol, can be hard/software

  

Unit 4, How Data travels.

IP address for each computer: stands for Internet Properties
All info send over internet contains packets/frames of info

• Header:Senders/Receiver IP, Packet #
• Payload:Data
• Trailer:Data at end of packet 

 Routers remove Frame, move info to computer destination, Routers search for easiest path to final destination
Data can "hop" between routers
                 "Ping" evaluates connection between the sender and receiver. Is it a good connection or not.

• Firewall is a protector for your computer, they are custom made/modified

Internet is a fast/efficient way to deliver data.

First 9 Weeks

What is your impression of the first 9-weeks of high school?

My impression of the first 9 weeks was not a bad one, the transition was not easy. I needed to memorize a new building and class schedule. Other than that it was an alright start. Thought the school itself needs a redo, the AOIT program has been great and very helpful.

What has been difficult about the transition from middle school? 

Getting up at 6:00
The most difficult thing to get used to was the new surroundings, people and layout of the school. I still have not seen most of the pods, upstairs area and the sports fields.

What has been easy about the transition? 

The easy parts of the move is the 4 class schedule, new classes every semester and a 40 minute lunch period.

What have you learned about yourself?

I have learned 3 things
1. I need my sleep
2. I have terrible time management skills (work in progress)
3. I will need a snack before 3rd period.
