    This site provides Activity types for various content areas. If you click on each of the active content links you will see that a variety of activitie types are identified as well as types of technology that could be used to facilitate that activity. I found it very interesting and would be helpful for tech coaches or teachers.

    This is a good site, It would be very helpful for a person just getting started to look at their content area and see the types of activities listed (select the content area and then select the activity type link within the page). Each activity listed also has a list of technology that could be used to facilitate that activity.

Internetworking Technology Handbook - Internetworking Basics [Internetworking] - Cisco... - 0 views

  • The upper layers of the OSI model deal with application issues and generally are implemented only in software. The highest layer, the application layer, is closest to the end user. Both users and application layer processes interact with software applications that contain a communications component. The term upper layer is sometimes used to refer to any layer above another layer in the OSI model. The lower layers of the OSI model handle data transport issues. The physical layer and the data link layer are implemented in hardware and software. The lowest layer, the physical layer, is closest to the physical network medium (the network cabling, for example) and is responsible for actually placing information on the medium.
  • Internetwork addresses identify devices separately or as members of a group. Addressing schemes vary depending on the protocol family and the OSI layer. Three types of internetwork addresses are commonly used: data link layer addresses, Media Access Control (MAC) addresses, and network layer addresses.
  • A data link layer address uniquely identifies each physical network connection of a network device. Data-link addresses sometimes are referred to as physical or hardware addresses.

  • End systems generally have only one physical network connection and thus have only one data-link address. Routers and other internetworking devices typically have multiple physical network connections and therefore have multiple data-link addresses.
  • As with most data-link addresses, MAC addresses are unique for each LAN interface.
  • MAC addresses are 48 bits in length and are expressed as 12 hexadecimal digits.

    An internetwork is a collection of individual networks, connected by intermediate networking devices, that functions as a single large network. Internetworking refers to the industry, products, and procedures that meet the challenge of creating and administering internetworks.

Official Google Blog: From the height of this place - 0 views

  • More Internet-enabled phones will be sold and activated in 2009 than personal computers.
  • Today, the computer for the rest of us is a phone.
  • Our infrastructure has to keep up with this growth just to maintain our current level of quality, but to actually make search smarter, our index and infrastructure need to grow at a pace FASTER than the web.

      I find this to be an excellent sentence that can be applied to public education as well.

  • One thing that we have learned in our industry is that people have a lot to say. They are using the Internet to publish things at an astonishing pace. 120K blogs are created daily — most of them with an audience of one. Over half of them are created by people under the age of nineteen. In the US, nearly 40 percent of Internet users upload videos, and globally over fifteen hours of video are uploaded to YouTube every minute. The web is very social too: about one of every six minutes that people spend online is spent in a social network of some type.
  • No one argues the value of free speech, but the vast majority of stuff we find on the web is useless. The clamor of junk threatens to drown out voices of quality.
  • When data is abundant, intelligence will win
  • The real potential of cloud computing lies not in taking stuff that used to live on PCs and putting it online, but in doing things online that were previously simply impossible.
  • Oil fueled the Industrial Revolution, but data will fuel the next generation of growth.
  • Now, the best technology starts with consumers, where a Darwinian market drives innovation that far surpasses traditional enterprise tools, and migrates to the workplace only after thriving with consumers.
  • Cloud computing levels that playing field so that the small business has access to the same systems that large businesses do. Given that small businesses generate most of the jobs in the economy, this is no small trend.
  • With facts, negotiations can become less about who yells louder, but about who has the stronger data.
  • Similarly, we manage Google with a long-term focus.

Seeing No Progress, Some Schools Drop Laptops - New York Times - 0 views

  • “The art of thinking is being lost,” he said. “Because people can type in a word and find a source and think that’s the be all end all.”

      I think what this teacher is saying is that the art of recalling is being lost. The art of thinking takes too long for some teachers, IMHO.
