Wild Cobra Lily Plants: Internetity, Bandwidth, World University and School

"Internetity," refers to the internet age, and supersedes and includes modernity and postmodernity, as a 'condition' informing much of social life today. (See MacLeod, Scott Gordon K. 2001. Gazing at the Box: Tourism in the Context of the Internet and Globalization (Internetity). Accessed online March 17, 2009. http://scottmacleod.com/anth250v.htm.)

In thinking about wiring 'the' One Laptop per Child countries for video-capable handheld devices, as a kind of humanitarian project (handheld devices are much more in use in the developing countries than are laptops) to make World University and School Wiki and related video-communication learning and teaching possible, here are list of bandwidth speeds from Wikipedia.

List of device bandwidths

From Wikipedia, the free encyclopedia

Jump to: navigation, search

This is a list of device bandwidths: the net bit rate (or, more informally, digital bandwidth) of some computer devices employing methods of data transport is quantified in units of kilobits per second (kbit/s), megabits per second (Mbit/s), or gigabits per second (Gbit/s) as appropriate. They are grouped by similar functionality, and then listed in order from lowest bandwidth to highest.

In addition, a common scale is used to better convey the magnitude of change to a non-technical person (for example: a 1.2 kbit/s telephone modem versus a 10,000 kbit/s DSL modem). Whether to use bit/s (b/s) or byte/s (B/s) is often a matter of convention. The most commonly cited unit (bit/s or byte/s) is shown in emboldened type. In general, parallel interfaces are quoted in byte/s (B/s), serial in bit/s. On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes, such as Ethernet, Serial ATA and PCI Express, quoted speeds are for the decoded signal.

Many of these figures are theoretical maxima, and various real-world considerations will generally keep the actual effective throughput much lower. The actual throughput achievable on Ethernet networks, for example (especially when heavily loaded or when running over substandard media), is debatable. The figures are also simplex speeds, which may conflict with the duplex speeds vendors sometimes use in promotional materials.

  • 1 byte = 8 bits
Note: All of the figures listed here use metric (base-10) abbreviations:
  • 1 kbit = 1,000 bits
  • 1 kB = 1,000 bytes
  • 1 MB = 1,000,000 bytes
  • 1 GB = 1,000,000,000 bytes
  • 1 TB = 1,000,000,000,000 bytes
and so on.
(See binary prefixes for additional information on this convention.)

[edit] Modems/Broadband connections

Note that the values given are maximum values, and actual values may be slower under certain conditions (for example, noisy phone lines). [2] Where two values are listed, the first value is the downstream rate and the second value is the upstream rate.

300 baud modems operating at 30 characters per second, were often described as "reading speed" since the characters scrolled across the screen at the same rate as most people can read. All modems are assumed to be in serial operation with 1 start bit, 8 data bits, no parity, and 1 stop bit (2 stop bits for 110-baud modems). Therefore, a total of 10 bits (11 bits for 110-baud modems) are needed to transmit each 8-bit byte. The "bytes" column reflects the net data transfer rate after the protocol overhead has been removed.

[edit] Local area network

Note: Actual data throughput is much less than bandwidth of the data transmitted due to overhead and other factors, so do not mistake its speed as actual data transfer rate. "Typically one can expect about ⅓–⅔ of the actual speed based on several factors such as traffic. Also, if there are problems in your physical layer causing retransmissions, your throughput will suffer as well." [23]

[edit] Wireless networking

Note: 802.11 networks are half-duplex; all stations share the medium. In access point mode, all traffic has to pass through the AP (Access Point). Two stations on the same AP which are communicating with each other will have all traffic pass the medium twice: once sent by the sender to the AP, then from AP to receiver, thus approximately halving the effective bandwidth.

Let's combine 10 Gbit/s Ethernet
fast bandwidth speeds together with HDMI Type B 20.4 Gigabits per second (which is 2.5 Gigabytes per second - GB/s) fast device bandwidths in something like the iPhone or android and you have video-capability.

Start by making this available to disadvantaged groups in Birmingham, Alabama, vis-a-vis OLPC?
