An application layer is the topmost layer in the TCP/IP model. It is responsible for handling high-level protocols, issues of representation. This layer allows the user to interact with the application. When one application layer protocol wants to communicate with another application layer, it for...
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 header that contains the address...
A sublayer of the Data Link Layer (Layer 2) in the OSI (Open Systems Interconnection) model of computer networking is called Medium Access Control (MAC). Its main duty is to control access to a network's shared communication medium, ensuring that various devices can transmit data effectively ...
A router is aphysical networking device, which forwards data packets between networks.Routers do the data analysis, perform the traffic directing functions on the network, and define the top route for the data packets to reach their destination node. Adata packetmay have to surpass multiple routers...
Single-Bit Error mainly occurs in Parallel Data Transmission. For example, if eight wires are used to send the eight bits of a byte, if one of the wire is noisy, then single-bit is corrupted per byte. Burst Error: The two or more bits are changed from 0 to 1 or from 1 to 0 is...
In Synchronous TDM, signals are sent in the form of frames. Time slots are organized in the form of frames. If a device does not have data for a particular time slot, then the empty slot will be transmitted. The most popular Synchronous TDM are T-1 multiplexing, ISDN multiplexing, and ...

A router is a networking device that forwards the packet based on the information available in the packet header and forwarding table. The routing algorithms are used for routing the packets. The routing algorithm is nothing but a software responsible for deciding the optimal path through which pac...
Point-to-point wiring:It has point-to-point wiring for individual segments. Disadvantages of Tree topology Difficult troubleshooting:If any fault occurs in the node, then it becomes difficult to troubleshoot the problem. High cost:Devices required for broadband transmission are very costly. ...
The internet is one of the biggest WAN in the world. A Wide Area Network is widely used in the field of Business, government, and education. Examples Of Wide Area Network: Mobile Broadband:A 4G network is widely used across a region or country. ...
