    4/2/12As of today, Tyler, Krystal, Harrison, Brandon, John, Priscilla, and Mailisa have passed Strata in the past week. I am very proud of my students because they have worked so hard to understand this complex information. I am hoping to have the other 6 pass this week!!!
    3/29/20123 Students have passed strata today. (4 Total)

    Handwriting Technology: Handwriting technology is something that manufacturers are trying to incorporate into notebooks. You would use a stylus to write on a pad and the software of the notebook would pick up your handwriting and convert it into typing.

    generally use small amounts of data. Facebook is a hard one because it seems as though it takes up small amounts of data but, while that is true, since it constantly updates it also takes that same amount of data each and every time it updates. all of this combined you should have guessed that the final available room would have to be the smallest room, due to the uneven amount of usage on the other users parts. this shows that the more demand there is the less space there is for the other users on the same network as you. those 4 people have used up 95% of the available bandwidth on the 1Mbps data connection. this leaves the last person to only have 5% of the network to use, hoping that the other 4 don't decide to do anything more data consuming than they already are. not only does this restrict the 5th person, but also the 3rd and 4th. the larger amount of data is being taken by YouTube and Facebook due to the way they go about using your data. I encourage you to use a Network monitor occasionally, to see just what is taking up all of your data and how much of it. this can help you show the users and yourself why its good to what i like to say "play fair" when using data. you don't want to use and abuse a connection, just because your allowed to, Think of the others on your network.
    Latency could be best described as how much traffic is being pushed through your network and how long it takes for you to send and receive data from a server. The best way i explain Latency is through the use of Online Video Games use of Ping trackers. What your ping is, is how long it takes your to respond to your hosts ping in ms (milliseconds). for example if you are on a type of network as listed above in my Bandwidth analogy, then you would have a high ping of something like 999 this may seem high, but in theory it is high. Because of the amount of network space that is being taken up, the gamer will likely be room 5 in the hotel getting the blunt side of the stick, meaning that he will Lag everywhere and not be able to even enjoy playing his game anymore. if you are on the network by yourself, depending on how fast your network is you should be in the 50-130 range. When looking at Ping something <50 (Less than 150) would be a network that is clear and very high in speed, something like a 25 Mbps network. But, something >150 (Greater than 150) would be a bad sign, meaning that your network is congested and you will likely not have an enjoyable experience.

    his room. eemail and the surfer room side by side in small compact rooms. Now, imagine that the party YouTube has, is actually all the data that has to be streamed to you to watch a single video (100 MB of data could be a 15 second YouTube video). Imagine that Facebook constantly entering and exiting his room, is actually how Facebook has to constantly update in order to notify you on updates, comments, replies, etc. Email is just your standard user who checks their email regularly and is not doing much. Considering emails only use large amounts of data when downloading attachments or loading a graphic heavy email. Email gets a small amount of space because it will only use close to about 5000 KB (which is roughly a quarter to 5 MB) for a heavy page. Finally, Imagine The surfer, is actually a basic web surfer (checks email frequently, browses on shopping sites, googles information, etc. Nothing heavy). a basic web surfer and a normal email user will take up the least amount of bandwidth because they generally use small amounts of data

    Bandwidth and Latency
    Bandwidth is the amount of data that can be transferred at any given time.
    I always use the analogy of the High Class hotel.
    Imagine there is a very classy hotel named 1 MeBits, the hotel can only hold a small amount of occupants at any given time, due to the sizing of the individual rooms. The hotel is just opening and there are only 5 rooms available. 4 of which the rooms are taken by YouTube, Facebook, email and a surfer. YouTube has the biggest room of them all because he stated he needs space for the large parties he hosts. Facebook has the room farthest away from anyone but needs a medium sized room because he says he constantly enters and exits his room. e

    IPv4 is a 32 bit address written in dot decimal form, for end user convenience (ex. 192.168.2.1). For visual comparison purposes, i will point out that IPv4 can be recognized by it being split into 4 octets while IPv6 is split into 8.
