Since ADSL2 is an enhanced version of ADSL, or Asymmetrical Digital Subscriber Line, it has faster download rates and greater resistance to line noise. Line noise refers to the variation in a transmitted signal that typically occurs in electric connections.Know More
ADSL2 also has an improved range compared to its ADSL counterpart that uses the same copper wires. An improved range automatically translates to a greater coverage and better transmission rates. In order to save power, ADSL2 incorporates a stand-by-mode that also reduces the amount of time needed for initialization from 10 seconds in the traditional ADSL connection to about 3 seconds. Like other improved technologies, ADSL2 is reverse compatible with ADSL meaning ADLS2 equipment can be used at ADSL specs. This greatly simplifies the process of upgrading from ADSL to ADSL2.
Both ADLS2 and ADSL are broadband connections that are capable of concurrently transporting numerous traffic types and signals. They achieve this by properly managing the available bandwidth from a two-wire pair used by telephone systems. This allows them to receive and transmit data of varying types at faster speeds than a single channel connection. Apart from ADSL2 and ADSL, there is ADSL+, which is also an upgrade to ADSL that provides greater speeds compared to both ADSL2 and ADSL.Learn more about Internet & Networking
Wi-Fi is a brand name for short-distance wireless communication networking technology, based on 802.11 standards that Wi-Fi Alliance adopted from IEEE, while wireless stands for computer network that is not connected by cables and utilizes cellular towers for data transmission.Full Answer >
A repeater is a device that has single input and output ports, and makes it possible for signals to be transmitted across a network for long distances by conditioning the received signal and retransmitting the conditioned signal to the various segments while a hub is simply a repeater with multiple input and multiple output ports. Both hubs and repeaters strengthen an incoming data signal by regenerating it to reach its destination. Otherwise, the data signal will be subjected to attenuation.Full Answer >
A toolbar is part of the user interface of a specific program that allows the user access to certain program controls, while a taskbar allows for access to different programs. A taskbar is usually at the edge of the display for an operating system such as Windows and provides a way for the user to open, close or switch between programs.Full Answer >
The Internet is a broad public network that anyone can access through an Internet service provider while in contrast, an intranet is a private network maintained by an organization for the use of its own employees, members or others who are explicitly permitted access.The primary difference between the Internet and an intranet has to do with accessibility.Full Answer >
