3.4 sliding window protocols In the previous protocols, data frames were transmitted in one direction only. In most practical situations, there is a need for transmitting data in both directions. Pipelining is primarily used to create and organize a pipeline of instructions for a computer processor to processes in parallel. Typically, pipelining is an ongoing process where new tasks are added frequently and completed tasks are removed.

In computer networking and telecommunication, a frame is a digital data transmission unit or data packet that includes frame synchronization, i.e. a sequence of bits or symbols making it possible for the receiver to detect the beginning and end of the packet in the stream of symbols or bits.

COMPUTER NETWORKS MODEL QUESTION PAPER WITH SOLUTION Q-1(a) Piggybacking is used to improve the efficiency of bidirectional transmission. When a frame is carrying data from A to B, it can also carry control information about frames from B; when a frame is carrying data from B to A, it can also carry control information about frames from A. (f) The preamble is a 56-bit field that provides that we would be playing marriage broker to computer networks and studio audio. What you get from this is nearly as hot as a couple on their wedding night: On one RJ-45, two-way multiple audio channels, sophisticated control and data capability, and built-in computer compatibility. You can use Livewire+ as a simple soundcard replacement – an audio interface connecting to a PC with an RJ-45

Piggybacking can be defeated by logging out before walking away from a workstation or terminal or by initiating a screensaver that requires re-authentication when resuming. Frames are transmitted in both directions. It requires a full duplex communication channel. i. It uses Piggy Backing which means that the outgoing acknowledgement is delayed so that they can be hooked to the next outgoing data frame.

The Ethical Issues Surrounding Wi-Fi. Piggybacking is a bi-directional data transmission technique in the network layer (OSI model). It makes the most of the sent data frames from receiver to emitter, adding the confirmation that the data frame sent by the sender was received successfully (acknowledgement). When computer networks link people as well as machines, they become social networks. Such computer-supported social networks (CSSNs) are becoming important bases of virtual communities, computer.

Such computer-supported social networks (CSSNs) are becoming important bases of virtual communities, computer The networks and routers may have different delays, which may vary over time. The RTT therefore is also variable. It makes difficult to set timers. TCP allows varying timers by using an adaptive retransmission algorithm. It works as follows.
