CommTech: My Website

This week we worked on making our own website.
Check mine out :)

CommTech: Networking Day 2

Today in CommTech we learned about devices and which belong to each step of the OSI Reference Model. In layer 1, which is Physical, the devices are Hub and Repeater Media. In layer 2, Data Link, there's a NIC and a Bridge, along with a switch. In Layer 3 Network, there's the router. And in the remaining layers there is only the software programs of a computer. We also learned the different types of media and how fast they travel.  Along with that, we learned how each device works and how many of them cause a collision domain, which is  a place where collisions of data occur. Tomorrow Ms. Rod won't be here, so although we get to catch a break from Networking, we'll probably be starting on getting ideas for our website!

CommTech: NETWORKING

      Today in Communications Technology, we started our lessons on networking and how it works. To begin, we learned the OSI (Open System Interconnect) Reference Model:
7. Application: browsers, any network application/ PDU: Data
6. Presentation: common data formal, encryption and compression/ PDU: Data
5. Session: end to end connections, virtual sessions (chatting, aim)/ PDU: Data
4. Transport: Quality of Service, flow control/ PDU: Segments
3. Network: Logical addressing, IP address, dynamic address, Routing/ PDU: Packets
2. Data Link: Media Access Control (MAC) Physical or MAC address/ PDU: Frames
1. Physical: binary, bits & voltage/ PDU: Bits
      PDU stands for protocol data units. Protocol is a set of rules. To send a message to another computer, it must pass through the 7 steps of the OSI Ref. Model, then through media, which is glass, water, or air. As it goes through these steps, the message is encapsulating (wrapping data). As it reaches its destination, it decapsulates, or unwraps.
      Next we learned about different units of data. First is bits, which is the smallest unit of data. A cookie is 4 bits, or 1/2 of a byte. A byte is 8 bits. A Kilobit is 1000 bits (Kb) and a Kilobyte is 8000 bits (KB), or 1000 bytes. A Megabite is 1,000,000 bits (Mb) and a Megabyte is 8,000,000 bits, or 1,000,000 bytes. The same pattern of times 8 repeats for Giga (1,000,000,000) and Tera (1,000,000,000,000).
      Lastly, RAM stands for Random Access Memory. HTTP stands for hyper text transfer protocol, and HTTS stand for hyper text transfer secure. URL means uniform resource locator, and FTP means file transfer protocol.

My Flash Movie

 

CommTech: Flash Part 3

Flash is really really hard. Today we tried to make our own mini animation movie...everything we had to do took me like twenty tries. I really miss Photoshop.

CommTech: Flash Part 2

Today was our first day back from winter break, even though the banks and post office aren't even open. Anyways, we took characters and a background in Flash and made a space scene with it. I think tomorrow we are going animate it and learn how to put in 3D text, or work with shape tweens.
