When one application layer protocol wants to communicate with another application layer, it forwards its data to the transport layer. There is an ambiguity occurs in the application layer. Every application cannot be placed inside the application layer except those who interact with the communication ...
7. Computer Networks Computer network studies concentrate on analyzing, designing, and implementing interconnected computer systems. The internet, an illustrative network, links computers globally. Computer scientists explore diverse connection methods, such as light signals or radio waves, to forge these l...
Functions of Transport Layer: Service-point addressing:Computers run several programs simultaneously due to this reason, the transmission of data from source to the destination not only from one computer to another computer but also from one process to another process. The transport layer adds the h...
Single-Bit Errordoes not appear more likely in Serial Data Transmission. For example, Sender sends the data at 10 Mbps, this means that the bit lasts only for 1 ?s and for a single-bit error to occurred, a noise must be more than 1 ?s. Single-Bit Error mainly occurs in Parallel Da...
Computer Network tutorial provides basic and advanced concepts of Data Communication & Networks (DCN). Our Computer Networking Tutorial is designed for beginners and professionals. Our Computer Network tutorial includes all topics of Computer Network such as introduction, features, types of computer netwo...
There are some limitations of medium access control in computer networks: Restricted to Shared Medium:Shared network mediums are the only medium for many MAC protocols. MAC protocols might not be the most effective option when dedicated point-to-point connections are required (such as point-to-po...
FDM is commonly used in TV networks. It is used in FM and AM broadcasting. Each FM radio station has different frequencies, and they are multiplexed to form a composite signal. The multiplexed signal is transmitted in the air. Wavelength Division Multiplexing (WDM) ...
This topology delivers better fault tolerance because if any network device fails, it won't affect the network, as other devices can transfer information. The Mesh networks self-configure and self-organize, finding the quickest, most secure way to transmit the data. ...
