- Hi friends,
Technology had made us to the peak. Many of us are using Internet but we don't know some of the Concepts in it. Let me share with you the Basic Things to be known which we are using in our day to day life.
- Modem:
- A modem is a device that converts digital signals, from a computer, into analog signals for transmission over telephone lines. A modem also converts incoming analog signals into digital signals. 56K means that this type of modem has the ability to transmit at up to 56,600 bps.
- ADSL:
- ADSL is a type of high-speed Internet access for consumers. ADSL stands for Asymmetric Digital Subscriber Line. This is a technology that allows for digital transmission over existing telephone lines. The term 'asymmetric' refers to the fact that the speed that you send data can be different than the speed that you can receive data. Therefore, a typical user will have a faster download speed than upload speed through ADSL. ADSL service is typically many times faster than a 56k modem while allowing for regular phone/voice usage simultaneously on the same telephone line.
- Bandwidth:
- Bandwidth refers to how much data is transmitted over a given period of time. For digital devices, bandwidth is measured in bits per second (bps).
- Cable Modem:
- Cable modem service is a type of high-speed Internet access offered by local cable companies for consumers. Using the same coaxial cable used for TV signals, the speed of downloading data is typically many times faster than a 56K modem. Typically, upload speed is restricted to only 56Kbps, more than enough for normal, fast "surfing" of the Internet. Cable modem service is an "always-on" type of connection, which is especially vulnerable to hacker attacks. Users can prevent unauthorized access with a software firewall product.
- DSL:
- DSL is a type of high-speed Internet access for consumers. DSL stands for Digital Subscriber Line. This is a technology that allows for digital transmission over existing telephone lines. DSL service is typically many times faster than a 56K modem while allowing for regular phone/voice usage simultaneously on the same telephone line. Although DSL service does not exist in all areas, it is currently more available than cable modem service.
- ISDN:
- ISDN is a type of high-speed Internet access typically for businesses. ISDN stands for Integrated Services Digital Network. ISDN is conceptually the integration of both analog or voice data together with digital data over the same network.
- ISP:
- An ISP, or Internet Service Provider, is a company that provides users access to the Internet.
- LAN:
- A local area network, or LAN, is a group of computers and/or devices that share a common communications line within a small geographic area such as within an office building. A typical LAN can provide extremely high-speed Internet access with just one high-bandwidth connection to an ISP.
