Question 1

Provide a high-level description of ATM.

Accepted Answer

Asynchronous Transfer Mode (ATM)is a high-speed network transport method for data,voice,video,and multimedia applications.ATM consists of an interface and a protocol that is able to switch both constant and variable bit rate traffic over a common transmission channel.ATM is also composed of hardware,software,and media that conform to ATM protocol standards.

A) circuit 
B) switching 
C) relay 
D) packet D

Question 3

What is the role of the frame relay assembler/disassembler (FRAD)in frame relay communications?

Accepted Answer

Frame relay uses a frame relay assembler/disassembler (FRAD)to convert packets.A FRAD is often a module in a router,switch,or chassis hub.A FRAD is a device that connects the customer's LAN to a frame relay network and is responsible for encapsulating (assembling)packets from the LAN so that they can be sent over the frame relay WAN.The FRAD also de-encapsulates (disassembles)frame relay-formatted data so that it can be read by the local network.
