What is the difference between leased line connection and dial up connection?

Answer 1

Broadband

In general, broadband refers to telecommunication in which a wide band of frequencies is available to transmit information. Because a wide band of frequencies is available, information can be multiplexed and sent on many different frequencies or channels within the band concurrently, allowing more information to be transmitted in a given amount of time (much as more lanes on a highway allow more cars to travel on it at the same time). Related terms are wideband (a synonym), baseband (a one-channel band), and narrowband (sometimes meaning just wide enough to carry voice, or simply "not broadband," and sometimes meaning specifically between 50 cps and 64 Kpbs).

leased line

A permanent telephone connection between two points set up by a telecommunications common carrier. Typically, leased lines are used by businesses to connect geographically distant offices. Unlike normal dial-up connections, a leased line is always active. The fee for the connection is a fixed monthly rate. The primary factors affecting the monthly fee are distance between end points and the speed of the circuit. Because the connection doesn't carry anybody else's communications, the carrier can assure a given level of quality.

For example, a T-1 channel is a type of leased line that provides a maximum transmission speed of 1.544 Mbps. You can divide the connection into different lines for data and voice communication or use the channel for one high speed data circuit. Dividing the connection is called multiplexing.

Increasingly, leased lines are being used by companies, and even individuals, for internet access because they afford faster data transfer rates and are cost-effective if the Internet is used heavily.

Answer 2

The main difference between a DSL connection and a dial up connection is that the latter uses a phone line and a modem to connect to the Internet and you cannot use the phone while trying to make a connection. A DSL connection is much faster, you can talk on the phone while being connected to the Internet and the connection is always on.

Answer 3

A leased line, also called a T1 connection, by definition, is a permanent and dedicated high performance telecommunications network connection between two sites or locations. It's main purpose is to carry voice, data and internet traffic via a copper or fiber optic connection that guarantees a single open circuit at all times. This is usually used by businesses to connect their branch offices. Dial up connection on the other hand is a readily available, reliable and cheap method of connecting to the internet. Access to the internet is established by simply dialing to an internet service provider via public telephone lines. In a sense, it is just like a phone call except that the parties at both ends are computers, not people.

Answer 4

ADSL is a broadband or fast internet connection which runs above your telephone line making for much higher broadband speeds and download times are greatly reduced when using ADSL rather than a dialup connection which is typically much slower than ADSL and causes your computer to disconnect when your telephone rings as the connection to the internet is made through and along your telephone line so that you cannot use them both together .

Answer 5

A dedicated Internet connection usually refers to a connection that is "always on". In other words, the connection to the Internet Service Provider (ISP) is always established. Examples of this type include cable modems, fiber lines, or leased lines (e.g., T-1/OC-3).

In contrast, "dial-up" Internet usually refers to a connection provided by a telephone modem that only establishes a connection to the Internet Service Provider (ISP) when the user requests. This form of network connection is common in areas where dedicated connections are not possible, but telephone networks are available.

Telephone modems have a typical maximum speed of around 56kbps, while dedicated connections can range from 64kbps (DSL) to nearly 40Gbps (OC-768).
