Answers
A WIDE AREA NETWORK CONNECTION TYPE
Computer networking extending over a large geographical area established with leased telecommunication networks is known as Wide Area Network.
DIGITAL SUBSCRIBER LINE
DSL connection allows you to connect to the internet with the use of a modem through a dedicated pair of copper wires within your telephone lines.
It is the most common broadband connection in homes today.
Digital Subscriber Line is not a wide area network as it connects to a phone line having broadband connection and provides service within a small region.
HIGH-LEVEL DATA LINK CONTROL
It is a group of data-link protocols. Data that has to be transferred is arranged into addressable frames and then HDLC is used to transmit these synchronous data packets from point to point.
Hence, HDLC is a WAN because it works in a large geographical area.
ASYNCHRONOUS TRANSFER MODE
It is a switching technique that allows digital transmission of multiple traffic, including data, video signals, telephony over one network.
Yes. ATM is a wide area network because it uses fixed-length cells and travels a wide area.
