List of computer size categories. From Wikipedia, the free encyclopedia. This illustration shows the development of computers, from huge room-sized computers in the 1940s and 1950s (left-most photo) to smaller personal computers over the 1980s to the 2010s.
New US DOT Hazmat Safety Rule to Place Lithium Battery Limits in Carry-on Baggage on Passenger Aircraft Effective January 1, 2008. Passengers will no longer be able to pack loose lithium batteries in checked luggage beginning January 1, 2008 once new federal safety rules take effect.
Unfortunately, services like APOBox also use the USPS as an intermediary, so they will be affected by the changes as well. The USPS restrictions define lithium-ion batteries as dangerous goods, under the ICAO (International Civil Aviation Organization) TechniÂ­cal Instructions. In April 2011, the U.S. House of Representatives passed a rule barring the Obama administration from imposing limits on shipments of lithium-ion batteries by air.
