Pc to Phone Calls
To those who may not be familiar, the term Broadband is used to compare frequency bandwidth. These broadband frequencies are capable of transmitting large quantum of data at a higher speed than narrowband frequencies. Besides, broadband enables multiple voice, video or data channels simultaneously.
The Internet may be defined as a system of interconnected computer network worldwide that enables interchange data by packet switching using the standardized Internet Protocol Suite (TCP/IP). To put it briefly, Internet consists of millions of private and public, academic, business, and government networks ranging from local to global technologies.
Needless to say, the Internet holds a host of information resources and information services including electronic mail, online chat, file transfer and file sharing, online gaming, and the inter-linked hypertext documents and other resources of the World Wide Web (WWW).
Broadband Internet access, often referred to as broadband, is high-speed Internet access as compared to the standard dial-up access using a modem. It may be noted that dial-up modems are only capable of maximum bitrate of 56 kbit/s (kilobits per second) and require the full use of a telephone line. But broadband technologies provide double this speed without interfering with the telephone use.
Transfer speeds for Broadband are reported to be 50 times faster than dial-up modems, enabling users to download mp3s (compressed digital audio files) or films without having to wait indefinitely. Broadband connections are offered on a variety of platforms, including DSL (Digital Subscriber Line), cable, satellite, and wireless.
It is common knowledge that dial-up Internet uses a phone line to access the Internet. Your computer uses its modem to make a standard call to an Internet Service Provider, which then connects you to the WWW. The broadband, on the other hand, is provided in a number of ways - over a phone line, by cable, wirelessly, or by satellite, as is needed.
An Internet is a global network connecting millions of computers. More than 100 countries are linked into exchanges of data, news and information. It may not be incorrect to state that the Internet is today a public, cooperative, and self-sustaining facility accessible to hundreds of millions of people worldwide. One of the noteworthy aspects about the Internet is that nobody actually owns it. It is a global collection of networks of varying sizes - big, medium and small. These networks connect together in multiple ways.
Dial-up Internet connectivity is the widely used type of access promoted by Internet Service Providers (ISP). The connection is economical but slow. This connection t enables users to connect via a local serve that exhibits strength of a standard 56 Kilobits per second modem. Of course, broadband technology enables greater information-
The fundamental difference between dialup and broadband connections, it may be concluded, is the manner in which the connection is made from PC to the Internet. A dialup service connects to the Internet through a telephone line with a maximum speed of 56kbps. Broadband, on the other hand, denotes a connection that has capacity to transmit large amount of data at high speed. Presently a connection having download speeds of 256kbps or more is classified as broadband.
