Data Communication

Data Communication :
Data communication is the exchange of data between two devices via some form of transmission medium. Data communication is said to be local if communication devices are in the same building or a similar restricted geographical area.

The Components of Data Communication

Message : 
It is the information or data to be communicated. It consists of text, numbers, symbols, pictures, videos, sounds, and any other media formats
Sender : 
The device or person that sends the message.
Receiver: 
The device or person that receives the message.
Transmission Medium : 
The physical path through which the message travels from sender to receiver. Examples include cables, fiber optics, and wireless signals.
Protocol : 
A set of rules and conventions that determine how data is transmitted and received. Protocols ensure that the sender and receiver understand each other.

 ### Network Layer: Design Issues and Key Concepts **Network Layer** is responsible for data transfer between devices on different networks. It determines how data is routed from the source to the destination, ensuring it follows the best path. ### 1. **Design Issues in the Network Layer:**    - **Routing**: Deciding the best path for data to travel across the network.    - **Congestion Control**: Preventing network overload, ensuring smooth data flow.    - **Packet Forwarding**: Moving data packets from one network to another.    - **Error Handling**: Detecting and correcting errors that occur during data transmission. ### 2. **Routing Algorithms**: A Detailed Explanation Routing algorithms are methods used by network devices (like routers) to determine the best path for data to travel from its source to its destination. The goal of these algorithms is to ensure that data packets reach their destination efficiently, quickly, and with minimal...
