Cable and DSL modem are typically external devices

Friday, January 22nd, 2010

Both cable and DSL connection are significantly faster then dial-up modem connection. However, there is often debate over which is the faster of two.

Cable and DSL modem are typically external devices that connect to your computer’s ethernet port. However, a cable modem connects to cable wiring while a DSL modem connects to a phone jack. While these are significantly different connection, they both provide the same “always – on” Internet access for your computer. Both cable and DSL Internet connections have increased in speed over the last few years. As of early 2005, a typical cable connection supports speeds of 2 to 3 mbps, while a typical DSL connection supports speeds of 768 Kbps to 1.5 Mbps. This means cable modem usually have the capability to be faster than DSL modems.

However, a cable modem shares bandwidth with other computer in the area that also have cable Internet connections. If there are many people in your neighborhood that use the same cable service, it is likely your data transfer speeds will be reduced. DSL, on the other hand, is a direct line to the phone company, and therefore is not affected by other users. So DSL generally offers a more consistent speed.

Touch To Operate – a new innovation

Friday, January 22nd, 2010

Finger touch on a touchscreen is detected by technologies embedded in in the handset, and the location of touches within the display area acts as an input device like any keyboard or mouse, to interact with menu of the phones. Successfully infusing a man’s first sense of touch to a machine requires a lot of technologies to be applied , including resistive principle,surface acoustic wave technology, capacitive technology,strain gauge, optical imaging, dispersive signal technology, etc.

Resistive touch panel contains many layers sandwiched by thin space that act as a medium to pass on the touch sense. sharp objects can damage the layers which are otherwise water and dust resistant. surface acoustic wave technology’s ultrasonic wave help pass the touch sense.

Telecom Device For The Deaf

Friday, January 22nd, 2010

Telecommunication devices for the deaf are widely known. These enable persons with no hearing to make or receive telephone calls. The device is attached to a telephone calls. The device is attached to a telephone and resembles a small keyboard with a screen to display the incoming or outgoing messages. Some TDDs have a paper printout to record a permanent copy of the conservation.

To use a TDD, the user types a message on the keyboard that is automatically converted into tones and transmitted over the phone line to another TDD , which converts the message back into text room. In this system, both the sender and the receiver of the message must have access to the technology.

Although these technologies are not typically used in the class room they enables student with disabilities to interact with each other outside of the school environment for both academic and social reasons, just their non-disabled peers do.
