We'll begin our mission with the originator- the telephone. Since it's invention, the device has gotten smaller, portable, and even wireless. Accessories such as answering machines can attach to your phone or phone line for friends, family and/or clients and customers to leave you an important message when you're unavailable to take a call. All-in-one answering machine/telephone contraptions have gained substantial popularity in recent years as the price dropped with the advancement of technology.

Facsimile machines, also known as "fax" machines for short, take text or images from a piece of paper and transfer the data to another fax machine anywhere in the world via telephone lines. Much like the recent popularity of answering machine/telephone combinations and other telecommunication devices, technology has advanced to bring the price and size down and the convenience of all-in-one equipment for the average consumer. Phone/fax/copy/printer combinations are in a growing number of households across the country and around the globe. How are the new networks different?

As a result, both technology suppliers and service providers are increasingly in the business of providing telecommunications in all media simultaneously rather than specializing in a particular type such as voice, video, or data.
Second, the networks are built in layers, from the physical layer, which is concerned with the mechanical, electrical and optical, and functional and procedural means for managing network connections to the data, network, and transport layers, which are concerned with transferring data, routing data across networks between addresses, and ensuring end-to-end More info: ccent salary
