The process of combining the data streams is known as multiplexing and hardware used for multiplexing is known as a multiplexer. Multiplexing is achieved by using a device called Multiplexer ( MUX) that combines n input lines to generate a single output line. Multiplexing follows many-to-one, i.e., n input lines and one output line.
Sep 6, 2023 · Types of Framing. Framing can be of two types, fixed sized framing and variable sized framing. Fixed-sized Framing. Here the size of the frame is fixed and so the frame length acts as delimiter of the frame. Consequently, it does not require additional boundary bits to identify the start and end of the frame. Example − ATM cells.
In the OSI model, the data link layer is a 4 th layer from the top and 2 nd layer from the bottom. The communication channel that connects the adjacent nodes is known as links, and in order to move the datagram from source to the destination, the datagram must be moved across an individual link. The main responsibility of the Data Link Layer is ...
The main steps in circuit switching are as follows: 1. Call Establishment Phases: Request for Connection: The conversation starts with one device (the caller) asking the other (the callee) to connect. The user often initiates this request by picking up the phone and calling a number for example. Resource Reservation:
The way in which data is transmitted from one device to another device is known as transmission mode. The transmission mode is also known as the communication mode. Each communication channel has a direction associated with it, and transmission media provide the direction. Therefore, the transmission mode is also known as a directional mode.
PPP Protocol. The PPP stands for Point-to-Point protocol. It is the most commonly used protocol for point-to-point access. Suppose the user wants to access the internet from the home, the PPP protocol will be used. It is a data link layer protocol that resides in the layer 2 of the OSI model. It is used to encapsulate the layer 3 protocols and ...
