Which one of the following statements referring to mobile Internet access is FALSE?
3G stands for Third
Generation and 4G
for Fourth
Generation.
A USB modem or Internet
dongle is a device with
which you can connect to
a 3G/4G network to
access the Internet.
A 3G/4G network is a high
speed data network used by
suppliers of mobile
cellphones for broadband
services and Internet
connection.
A USB modem looks
like a flash disk and
operates without a
SIM card.

Technically, the last statement is false. All cellular devices operate using a SIM card, they are essentially how a network service provider (I.e. AT&T, Verizon, et. al.) identify their devices and know what level of service to provide to the device when it sends/receives signals from their tower. Some USB wireless broadband devices do look like USB thumb drives, however, they will either contain an integrated SIM card or have a spot for a replaceable SIM card.

One main difference is that a graphing calculator can graph out functions while a scientific calculator cannot. there are some scientific calculations that have built-in table functions, but generally (and obviously) scientific calculators are not built to be able to graph. graphing calculators have larger screens to accommodate for their eponymous use.furthermore, graphing calculators are usually more advanced. because of the specifications needed (like ram, processor) to be able to generate graphics, graphing calculators are able to support more sophisticated functions/features. some graphing calculators have a computer-algebra system, like the ti-89 titanium. some support spreadsheets. some even support programmable games. some allow for connectivity with a computer to install new programs.we have to consider another major difference: the price. graphing calculations are way more expensive than scientific calculators. i believe this has to do with the history behind graphing calculators. for example, texas instruments basically holds a monolopy over graphing calculators. school keep using tis because that is what they are familiar with.
