Faxes: Traditionally used for business use, these send images on paper from one location to another using Internet connections or a phone line. They are often relied upon for sending important documents like contracts or anything else that requires a hard signature.
Telephones: Telephones have been in use for over 100 years. These tried-and-true communication portals have certainly evolved over the years, but today's technology makes worldwide calling cheaper and easier than ever.
"Snail" Mail: This nickname for letters, postcards, and documents send through the Postal Service is still relied upon for many communication needs. When a document must be tracked or a hard copy obtained, this remains one of the most reliable sources of communication. It is also the only choice for communication with some remote parts of the globe.
Cellular Phones: Cell phones are becoming increasingly smaller and more complex. They offer the convenience of telephones with a wireless portability that makes them usable almost anywhere. They range from basic phones with limited range to more complex personal communication devices with music playing capabilities (MP3), Internet access, and even keyboards for typing. The higher-end devices (such as the Blackberry) are considered "wireless hand-held devices" rather than cell phones, even though they feature calling as part of the package.
Text Messaging: Most cell phones produced today offer text messaging capabilities. Popular among teens and many other youthful users, these allow written messages to be sent through hand-held devices in the same fashion as a phone call would be made.
