DSL Providers are companies and agencies that offer DSL technology, bringing high bandwidth information to businesses and homes through copper telephone lines. To receive a DSL service, a local telephone service through the incumbent local exchange carrier (ILEC) is necessary. There are several DSL providers offering high-speed Internet connections. Some of the major DSL providers include Pacific Bell, SNET, Verizon, Qwest, SBC, Ameritech, Southwestern Bell and Bell South.

Flash memory is a kind of electronic memory chip. It is rewritable and does not need a continuous power supply. It is an Electrically-Erasable Programmable Read-Only (EEPROM) and a Non-Volatile Read Write (NVRWM) kind of a memory. Flash memory is used in computers (BIOS chips), MP3 players, video game consoles (memory cards), USB flash drives, mobile phones, and digital cameras (memory chips, CompactFlash or SmartMedia).

In computers, 3D (three-dimensional) means an image that provides the perception of depth. If such images are made interactive and the users become involved with the scene, the experience is described as virtual reality. For viewing and interacting with 3D images, you normally require a special plug-in viewer for your web browser. To gain the experience of virtual reality, more equipment may also be necessary. The process of creating 3D images can be divided into three phases: tessellation, geometry, and rendering. In the first phase of tessellation, models are made of individual objects using linked points that are made into a number of individual polygons or tiles. In the second phase, the polygons are transformed in various ways and subjected to lighting effects. In the third and final stage, the transformed images are rendered into objects with intricate detail.

Flash memory cards are solid-state, non-volatile electronic devices used for storing data. They are much smaller in size than disk drives and thus occupy less space. They can also work without a continuous power supply. They have very good transfer speeds and operate at 3.3 volts or 5 volts. They are also very robust and can function in extreme industrial conditions.

Contact management is a modern way of managing your contacts. However, it's not just an electronic address book that lists out your contacts such as phone numbers and addresses and appointments for the day. All this personal information can be integrated with e-mails and saved at one place so that you don't have to waste time searching. You can store history of the interactions with contacts and keep track of all activities related to them. All this information can be kept absolutely confidential by using a password.
