Mastering Computer Networks

Computer Networks

• Communication is the process of sending and receiving data between two or more devices over a network.

Network Components

• A set of devices connected by media link is called a network.
• A node can be a device that can send or receive data generated by other nodes on the network, such as a computer.
• The links connecting the devices are called links.

Data Transmission

• Full-duplex is the mode of data transmission in which data is transmitted in both directions simultaneously.
• Latency is the measure of the time it takes for a data packet to travel from one device to another in a network.
• Bandwidth is the maximum amount of data that can be transmitted over a network in a given time period.

Network Security

• Security measures are used to protect data transmitted over a network from unauthorized access.

Network Types

• A computer network is a telecommunication channel that allows us to share data with other computers or devices connected to the same network, also known as a network.
• The best example of a computer network is an internet connection.

Network Characteristics

• A network must be able to meet certain criteria, including:

• Criteria
